A 16-year-old boy is brought to his primary care physician for evaluation of visual loss and is found to have lens subluxation. In addition, he is found to have mild scoliosis that is currently being monitored. Physical exam reveals a tall and thin boy with long extremities. Notably, his fingers and toes are extended and his thumb and little finger can easily encircle his wrist. On this visit, the boy asks his physician about a friend who has a very similar physical appearance because his friend was recently diagnosed with a pheochromocytoma. He is worried that he will also get a tumor but is reassured that he is not at increased risk for any endocrine tumors. Which of the following genetic principles most likely explains why this patient and his friend have a similar physical appearance and yet only one is at increased risk of tumors?
Q52
Last night you admitted a 72-year-old woman with severe COPD in respiratory distress. She is currently intubated and sedated and her family is at bedside. At the completion of morning rounds, the patient's adult son asks that you and the team take a minute to pray with him for his mother. What is the most appropriate response?
Q53
A 16-year-old female is brought to the primary care clinic by her mother. The mother is concerned about her daughter’s grades, which have been recently slipping. Per the mother, the patient usually earns a mix of As and Bs in her classes, but this past semester she has been getting Cs and a few Ds. Her mother is also frustrated because she feels like her daughter is acting out more and “hanging out with some no-good friends.” Upon questioning the patient with her mother in the room, the patient does not say much and makes no eye contact. The mother is asked to leave the room and the patient is questioned again about any stressors. After rapport is established, the patient breaks down and tearfully admits to trying various drugs in order to “fit in with her friends.” She says that she knows the drugs “are not good for me” but has been very stressed out about telling her friends she’s not interested. Detailed questioning reveals that the patient has been using alcohol, cocaine, and marijuana 2-3 times per week. The patient becomes agitated at the end of the interview and pleads for you to not tell her mother. She says that she knows they’re illegal but is very afraid of what her parents would say. What is the best action in response to the adolescent’s request?
Q54
A 16-year-old female presents to her pediatrician's office requesting to be started on an oral contraceptive pill. She has no significant past medical history and is not currently taking any medications. The physician is a devout member of the Roman Catholic church and is strongly opposed to the use of any type of artificial contraception. Which of the following is the most appropriate response to this patient's request?
Q55
A 15-year-old girl is brought into the clinic for a second opinion by her mother. She was recently evaluated for possible alopecia areata after having presented to her family doctor with a 2-month history of noticeable bald patches. The mother was concerned because the treatment involved topical steroids. The patient is noted to have started high school earlier this year and has an attention-deficit/hyperactivity disorder that is treated with methylphenidate. The patient is afebrile and her vital signs are within normal limits. Physical examination reveals a moderately distressed young female playing with her hair. She has very short nails on both hands and patches of hair loss on the scalp. Which of the following is the most appropriate initial management for this patient's condition?
Q56
A 47-year-old woman is upset with her neighbor for playing music too loudly late at night. Rather than confront her neighbor directly, the woman makes a habit of parking her car in a manner that makes it difficult for her neighbor to park in his spot. Which of the following defense mechanisms is this woman demonstrating?
Q57
A 52-year-old man with a 20+ year history of smoking comes in today to talk about quitting. His wife has recently been trying to quit, and she wants him to quit with her. He has been resistant in the past, but he is now very willing to talk with you about it. Today, he seems like he really wants to make a change. What stage of change does this behavior correspond to?
Q58
While playing the catcher position in baseball, a 27-year-old male sustained a blow to his left testes which required surgical removal.

Question 51: A 16-year-old boy is brought to his primary care physician for evaluation of visual loss and is found to have lens subluxation. In addition, he is found to have mild scoliosis that is currently being monitored. Physical exam reveals a tall and thin boy with long extremities. Notably, his fingers and toes are extended and his thumb and little finger can easily encircle his wrist. On this visit, the boy asks his physician about a friend who has a very similar physical appearance because his friend was recently diagnosed with a pheochromocytoma. He is worried that he will also get a tumor but is reassured that he is not at increased risk for any endocrine tumors. Which of the following genetic principles most likely explains why this patient and his friend have a similar physical appearance and yet only one is at increased risk of tumors?
A. Variable expression
B. Locus heterogeneity (Correct Answer)
C. Anticipation
D. Incomplete penetrance
E. Pleiotropy
Explanation: ***Locus heterogeneity***
- This principle explains that **similar phenotypes** (like the Marfanoid habitus) can result from mutations at **different genetic loci**. In this case, two distinct genetic conditions (Marfan syndrome and MEN 2B for the friend) can both cause tall stature and long limbs, but only one is associated with pheochromocytoma.
- The patient's presentation of **lens subluxation**, **scoliosis**, and **Marfanoid habitus** strongly suggests Marfan syndrome, typically caused by *FBN1* mutations, which does not predispose to pheochromocytomas. The friend's similar appearance coupled with pheochromocytoma suggests a different genetic condition, such as **Multiple Endocrine Neoplasia Type 2B (MEN 2B)**, which involves *RET* gene mutations.
*Variable expression*
- This describes the phenomenon where individuals with the **same genotype** exhibit **different degrees of severity** in their phenotype. It doesn't explain why two individuals with similar physical features have different underlying genetic causes and therefore different risks for specific complications like tumors.
- Variable expression would suggest that if both individuals had the same genetic mutation, they might show different levels of Marfanoid features or tumor development, but it wouldn't account for the complete absence of tumor risk in one.
*Anticipation*
- This refers to a genetic phenomenon where the **severity of a genetic disease increases** and/or the **age of onset decreases** in successive generations.
- Anticipation is typically seen in disorders caused by **trinucleotide repeat expansions** (e.g., Huntington's disease, myotonic dystrophy) and is not relevant to explaining different tumor risks with similar phenotypes across unrelated individuals.
*Incomplete penetrance*
- This occurs when individuals with a specific genotype **do not always express the associated phenotype**, meaning some individuals with the disease-causing mutation show no symptoms.
- Incomplete penetrance does not explain why two individuals with similar physical features have different genetic conditions leading to varied tumor risks; it focuses on whether a known mutation will manifest at all, not on different genetic causes for similar traits.
*Pleiotropy*
- This is when a **single gene mutation affects multiple seemingly unrelated phenotypic traits**. Marfan syndrome itself is an example of pleiotropy, as a mutation in *FBN1* affects the skeletal, ocular, and cardiovascular systems.
- While both conditions (Marfan syndrome and MEN 2B) exhibit pleiotropy, this principle doesn't explain why two different genetic conditions would cause similar Marfanoid features but distinct tumor risks. It describes the multiple effects of *one* mutation, not the possibility of *different* mutations leading to similar effects.
Question 52: Last night you admitted a 72-year-old woman with severe COPD in respiratory distress. She is currently intubated and sedated and her family is at bedside. At the completion of morning rounds, the patient's adult son asks that you and the team take a minute to pray with him for his mother. What is the most appropriate response?
A. "I understand what you are experiencing and am happy to take a minute." (Correct Answer)
B. "I'm sorry, but this is a public hospital, so we cannot allow any group prayers."
C. "I don't feel comfortable praying for patients, but I will happily refer you to pastoral care."
D. "While I cannot offer you my prayers, I will work very hard to take care of your mother."
E. "I also believe in the power of prayer, so I will pray with you and insist that the rest of team joins us."
Explanation: ***"I understand what you are experiencing and am happy to take a minute."***
- This response demonstrates **empathy** and **compassion**, acknowledging the family's emotional and spiritual needs during a difficult time.
- Participating in a brief prayer when invited by a patient's family, if comfortable, can build **trust** and strengthen the **patient-provider relationship**, showing respect for their beliefs.
*"I'm sorry, but this is a public hospital, so we cannot allow any group prayers."*
- This statement is **factually incorrect**; public hospitals generally permit and often support patients' and families' religious practices.
- It would be perceived as **insensitive** and disrespectful of the family's spiritual needs, potentially damaging the relationship.
*"I don't feel comfortable praying for patients, but I will happily refer you to pastoral care."*
- While referring to **pastoral care** is a good option when one is uncomfortable praying, directly refusing a simple, shared moment of prayer can still feel dismissive to a distressed family.
- The direct refusal, even with a follow-up referral, might not fully address the immediate emotional and spiritual support the family is seeking from the care team.
*"While I cannot offer you my prayers, I will work very hard to take care of your mother."*
- This response, while affirming commitment to medical care, explicitly denies the family's request for a shared moment of prayer, which can be perceived as **unempathetic** or cold.
- It prioritizes medical intervention over the holistic, spiritual needs of the family, potentially creating a distance in the provider-family relationship.
*"I also believe in the power of prayer, so I will pray with you and insist that the rest of team joins us."*
- While participating is appropriate, **insisting** that the entire team join can be coercive and infringe on the individual team members' **religious freedom** or comfort levels.
- Making assumptions about the entire team's beliefs and forcing participation is unprofessional and can lead to discomfort or resentment among staff.
Question 53: A 16-year-old female is brought to the primary care clinic by her mother. The mother is concerned about her daughter’s grades, which have been recently slipping. Per the mother, the patient usually earns a mix of As and Bs in her classes, but this past semester she has been getting Cs and a few Ds. Her mother is also frustrated because she feels like her daughter is acting out more and “hanging out with some no-good friends.” Upon questioning the patient with her mother in the room, the patient does not say much and makes no eye contact. The mother is asked to leave the room and the patient is questioned again about any stressors. After rapport is established, the patient breaks down and tearfully admits to trying various drugs in order to “fit in with her friends.” She says that she knows the drugs “are not good for me” but has been very stressed out about telling her friends she’s not interested. Detailed questioning reveals that the patient has been using alcohol, cocaine, and marijuana 2-3 times per week. The patient becomes agitated at the end of the interview and pleads for you to not tell her mother. She says that she knows they’re illegal but is very afraid of what her parents would say. What is the best action in response to the adolescent’s request?
A. Apologize and say that you must inform her mother because these drugs pose a danger to her health
B. Apologize and say that you must inform her mother because the use of these drugs is illegal
C. Apologize and say that you must inform legal authorities because the use of these drugs is illegal
D. Reassure the patient that there is confidentiality in this situation but encourage her to tell her mother (Correct Answer)
E. Agree to the patient’s request and do not inform the patient’s mother
Explanation: ***Reassure the patient that there is confidentiality in this situation but encourage her to tell her mother***
- It is crucial to maintain **confidentiality** with adolescent patients to build trust and encourage open communication, which is vital for effective care.
- While maintaining confidentiality, it is also important to **encourage the adolescent** to involve her parents, as parental support can be highly beneficial in addressing substance abuse issues and helping the patient navigate treatment.
*Apologize and say that you must inform her mother because these drugs pose a danger to her health*
- Breaching confidentiality, even for health concerns, can **damage the patient-provider relationship** and make the adolescent less likely to seek future medical help or disclose sensitive information.
- While the drugs do pose a danger, the **immediate step should be to build trust** and work with the patient, rather than immediately informing parents against their wishes unless there is an imminent threat to life.
*Apologize and say that you must inform her mother because the use of these drugs is illegal*
- The **illegality of drug use alone does not automatically override patient confidentiality** or mandate disclosure to parents in a medical setting for a minor.
- Focusing on the legal aspect without addressing the patient's immediate health and emotional needs can **alienate the patient** and deter them from engaging in treatment.
*Apologize and say that you must inform legal authorities because the use of these drugs is illegal*
- Healthcare providers generally are **not mandated to report drug use by minors to legal authorities**, especially when the patient is seeking help or making disclosures in a therapeutic context.
- Such an action would severely **breach trust** and discourage any minor from seeking medical help for substance use.
*Agree to the patient’s request and do not inform the patient’s mother*
- While confidentiality is important, completely agreeing to withhold information without encouraging parental involvement may **miss an opportunity for family support and intervention**.
- This approach might also **delay necessary family engagement** that could be beneficial for the patient's long-term health and recovery, especially given the severity and frequency of drug use.
Question 54: A 16-year-old female presents to her pediatrician's office requesting to be started on an oral contraceptive pill. She has no significant past medical history and is not currently taking any medications. The physician is a devout member of the Roman Catholic church and is strongly opposed to the use of any type of artificial contraception. Which of the following is the most appropriate response to this patient's request?
A. Suggest that the patient remain abstinent or, if necessary, use an alternative means of birth control
B. Explain that he will refer the patient to one of his partners who can fulfill this request (Correct Answer)
C. Refuse to prescribe the oral contraceptive
D. Tell the patient that he is unable to prescribe this medication without parental consent
E. The physician is obligated to prescribe the oral contraceptives regardless of his personal beliefs
Explanation: ***Explain that he will refer the patient to one of his partners who can fulfill this request***
- Physicians have a right to **conscientious objection** based on personal beliefs, but they also have an ethical obligation to ensure that patients receive appropriate medical care.
- Referring the patient to another qualified provider for the requested service fulfills both the physician's right to object and the patient's right to care, without imposing the physician's personal beliefs on the patient.
*Suggest that the patient remain abstinent or, if necessary, use an alternative means of birth control*
- While abstinence is a valid choice, suggesting it without offering the requested medical service is imposing the physician's personal beliefs on the patient, which is **unethical** in this context.
- Recommending only "alternative means" without directly addressing the patient's specific request for oral contraceptives does not adequately address her healthcare needs or autonomy.
*Refuse to prescribe the oral contraceptive*
- An outright refusal without providing an alternative option or referral **violates the ethical principle** of beneficence and the patient's right to access medical care.
- This action could be seen as abandoning the patient and is not consistent with professional medical ethics for handling conscientious objections.
*Tell the patient that he is unable to prescribe this medication without parental consent*
- In many jurisdictions, minors are legally allowed to obtain contraception **without parental consent** due to privacy and public health considerations (e.g., prevention of STIs and unintended pregnancies).
- This statement may be **legally incorrect** and serves as an excuse to avoid providing the requested service, rather than addressing the ethical dilemma of conscientious objection appropriately.
*The physician is obligated to prescribe the oral contraceptives regardless of his personal beliefs*
- While physicians have an obligation to provide care, they are generally **not obligated to perform services that violate their deeply held moral or religious beliefs**, provided they ensure the patient can access the service elsewhere.
- This option incorrectly states that personal beliefs must always be overridden for every medical service, ignoring the principle of conscientious objection while ensuring patient access to care.
Question 55: A 15-year-old girl is brought into the clinic for a second opinion by her mother. She was recently evaluated for possible alopecia areata after having presented to her family doctor with a 2-month history of noticeable bald patches. The mother was concerned because the treatment involved topical steroids. The patient is noted to have started high school earlier this year and has an attention-deficit/hyperactivity disorder that is treated with methylphenidate. The patient is afebrile and her vital signs are within normal limits. Physical examination reveals a moderately distressed young female playing with her hair. She has very short nails on both hands and patches of hair loss on the scalp. Which of the following is the most appropriate initial management for this patient's condition?
A. Antipsychotics
B. Lithium
C. Psychodynamic therapy
D. Selective serotonin reuptake inhibitors
E. Behavioral therapy (Correct Answer)
Explanation: ***Behavioral therapy***
- This patient's presentation with **patchy hair loss**, severely **short nails** (suggesting nail biting), and the act of playing with her hair points towards **trichotillomania**, a body-focused repetitive behavior (BFRB).
- **Behavioral therapy**, specifically **habit reversal training (HRT)**, is the first-line and most effective treatment for trichotillomania, focusing on awareness training, competing response training, and social support.
*Antipsychotics*
- Antipsychotics are generally reserved for conditions like **schizophrenia**, **bipolar disorder with psychotic features**, or severe **obsessive-compulsive disorder** (OCD) when other treatments have failed.
- While they can be used off-label for severe BFRBs, they are not the initial management for trichotillomania and carry significant side effects.
*Lithium*
- **Lithium** is primarily used as a **mood stabilizer** for **bipolar disorder** and is not indicated for trichotillomania or other BFRBs.
- It has a narrow therapeutic window and requires regular monitoring of blood levels.
*Psychodynamic therapy*
- **Psychodynamic therapy** focuses on exploring unconscious conflicts and past experiences to understand current behaviors.
- While it can be helpful for some mental health conditions, it is **not the primary or most effective initial treatment** for trichotillomania, where behavioral interventions are more directly targeted at the problematic habit.
*Selective serotonin reuptake inhibitors*
- **SSRIs** are effective for **depression**, **anxiety disorders**, and **obsessive-compulsive disorder (OCD)**.
- While trichotillomania shares some features with OCD, SSRIs are **not first-line** for trichotillomania and are generally considered as an augmentation strategy or for comorbid conditions, not as initial monotherapy.
Question 56: A 47-year-old woman is upset with her neighbor for playing music too loudly late at night. Rather than confront her neighbor directly, the woman makes a habit of parking her car in a manner that makes it difficult for her neighbor to park in his spot. Which of the following defense mechanisms is this woman demonstrating?
A. Displacement
B. Passive aggression (Correct Answer)
C. Regression
D. Sublimation
E. Acting out
Explanation: ***Passive aggression***
- This involves expressing **negative feelings indirectly** rather than openly addressing the conflict, which is exactly what the woman is doing by inconveniencing her neighbor with parking.
- She is avoiding direct confrontation but still demonstrating her anger and resentment through her actions.
*Displacement*
- This defense mechanism involves transferring an **emotional reaction from the original source** to a safer, less threatening one.
- While she is upset with her neighbor, she is not displacing her anger onto a different, unrelated target.
*Regression*
- This involves reverting to **earlier, more childish patterns of behavior** in response to stress or conflict.
- The woman's actions, while indirect, are not indicative of a return to immature behaviors.
*Sublimation*
- This defense mechanism involves channeling unacceptable impulses or emotions into **socially acceptable or productive activities**.
- Her actions are not productive or socially acceptable; instead, they are disruptive and aimed at annoying her neighbor.
*Acting out*
- This refers to expressing **unconscious emotional conflicts or impulses through behavior**, often in a destructive or self-destructive manner.
- While her actions are a form of behavior, "acting out" typically implies a more impulsive or self-harming nature than the deliberate, indirect aggression shown here.
Question 57: A 52-year-old man with a 20+ year history of smoking comes in today to talk about quitting. His wife has recently been trying to quit, and she wants him to quit with her. He has been resistant in the past, but he is now very willing to talk with you about it. Today, he seems like he really wants to make a change. What stage of change does this behavior correspond to?
A. Action
B. Preparation
C. Precontemplation
D. Maintenance
E. Contemplation (Correct Answer)
Explanation: ***Contemplation***
- The patient is **aware of the problem and willing to discuss quitting**, indicating he is seriously thinking about making a change.
- He "seems like he really wants to make a change" and is "very willing to talk" about it, which demonstrates **serious consideration** of behavior change.
- In contemplation stage, individuals intend to change **within the next 6 months** and are actively weighing pros and cons, but have not yet committed to concrete action plans.
- The patient has not mentioned setting a quit date or taking preparatory steps, which would be needed for the preparation stage.
*Preparation*
- This stage involves **commitment to action within 30 days** with concrete plans (e.g., setting a quit date, purchasing nicotine replacement therapy, joining a support group).
- The patient is only discussing and wanting to change, but has not yet made **specific plans or commitments** to quit.
- Simply being willing to talk does not indicate readiness for imminent action.
*Action*
- This stage involves **actively modifying behavior** or environment to overcome the addiction (e.g., has already stopped smoking).
- The patient is still actively smoking and has not yet initiated the quitting process.
*Maintenance*
- This stage is for individuals who have **successfully maintained behavior change for at least 6 months**.
- The patient has not yet quit smoking.
*Precontemplation*
- Individuals in this stage are **unaware or unwilling to acknowledge a problem** and have no intention of changing.
- The patient is clearly aware and willing to discuss the problem, moving well past this stage.
Question 58: While playing the catcher position in baseball, a 27-year-old male sustained a blow to his left testes which required surgical removal. Upon awakening from anesthesia, he jokes to his wife that he is now half the man that she once knew. Which of the following scenarios is a similar ego defense as the one above?
A. A cheating husband accuses his wife of doing the same
B. A husband angry at his wife takes out his anger on his employees
C. A religious woman with homosexual desires speaks out against gay marriage
D. A short-tempered male lifts weights to deal with his anger
E. A recently divorced man states he will finally be able to watch a football game without nagging (Correct Answer)
Explanation: ***A recently divorced man states he will finally be able to watch a football game without nagging***
- This scenario exemplifies **rationalization**, where an individual creates **plausible but false reasons** for their behavior or situation.
- The man is attempting to cope with the pain of divorce by focusing on a perceived "benefit," thereby **minimizing the negative emotional impact** of the loss.
*A cheating husband accuses his wife of doing the same*
- This is an example of **projection**, where an individual **attributes their own unacceptable thoughts or feelings to another person**.
- The husband avoids confronting his own guilt by displacing it onto his wife.
*A husband angry at his wife takes out his anger on his employees*
- This scenario demonstrates **displacement**, where emotions, particularly anger, are **redirected from the actual target to a less threatening one**.
- The husband cannot express his anger directly at his wife, so he expresses it towards his employees.
*A religious woman with homosexual desires speaks out against gay marriage*
- This is a classic example of **reaction formation**, where an individual **behaves in a way that is directly opposite to their true, unacceptable impulses or feelings**.
- The woman's outward opposition to gay marriage serves as a defense against her own unconscious homosexual desires.
*A short-tempered male lifts weights to deal with his anger*
- This scenario illustrates **sublimation**, an adaptive defense mechanism where **unacceptable impulses are channeled into socially acceptable activities**.
- The man's anger, an otherwise destructive impulse, is transformed into a productive activity like weightlifting.
Question 59: A 16-year-old boy is brought to the physician by his mother because she is worried about his behavior. Yesterday, he was expelled from school for repeatedly skipping classes. Over the past 2 months, he was suspended 3 times for bullying and aggressive behavior towards his peers and teachers. Once, his neighbor found him smoking cigarettes in his backyard. In the past, he consistently maintained an A grade average and had been a regular attendee of youth group events at their local church. The mother first noticed this change in behavior 3 months ago, around the time at which his father moved out after discovering his wife was having an affair. Which of the following defense mechanisms best describes the change in this patient's behavior?
A. Projection
B. Passive aggression
C. Regression
D. Suppression
E. Acting out (Correct Answer)
Explanation: ***Acting out***
- This defense mechanism involves **engaging in destructive or inappropriate behaviors** to cope with emotional distress, often
**unconsciously** expressing unmet needs or feelings.
- The patient's sudden and significant shift from a well-behaved, high-achieving student to one who skips classes, engages in bullying, and smokes cigarettes can be seen as an expression of his emotional turmoil following his parents' separation.
*Projection*
- **Projection** is an attributional defense mechanism in which a person **attributes their own unacceptable thoughts or feelings to
another person**.
- While the patient is exhibiting negative behaviors, he is not explicitly attributing his own internal conflicts or feelings onto others; rather, he is demonstrating them through his actions.
*Passive aggression*
- **Passive aggression** is characterized by expressing negative feelings indirectly, often through **procrastination, stubbornness, or
inefficiency**, rather than direct confrontation.
- The patient's behaviors, such as bullying and skipping classes, are more overt and direct expressions of anger and distress, not indirect resistance.
*Regression*
- **Regression** involves reverting to **earlier, less mature behaviors or coping mechanisms** in response to stress.
- While some of his behaviors could be seen as less mature, the primary mechanism at play here is the direct, behavioral expression of conflict, rather than a return to an earlier developmental stage of coping, such as thumb-sucking or bed-wetting.
*Suppression*
- **Suppression** is a **conscious, deliberate effort to push unwanted thoughts or feelings out of awareness**.
- The patient's behaviors are likely an unconscious or preconscious response to his distress; he is not actively trying to forget or ignore his problems but rather demonstrating his distress through his actions.
