A 57-year-old woman with type 2 diabetes mellitus comes to the physician for a follow-up examination. She previously had been compliant with her diet and medication but has had a 5-kg (11-lb) weight gain since the last visit 6 months ago. She reports that she often misses doses of her metformin. Her hemoglobin A1c is 9.8%. Which of the following is the most appropriate course of action?
Q2
A 34-year-old man presents to the local clinic with a 2 month history of midsternal chest pain following meals. He has a past medical history of hypertension. The patient takes lisinopril daily. He drinks 4–5 cans of 12 ounce beer daily, and chews 2 tins of smokeless tobacco every day. The vital signs are currently stable. Physical examination shows a patient who is alert and oriented to person, place, and time. Palpation of the epigastric region elicits mild tenderness. Percussion is normoresonant in all 4 quadrants. Murphy’s sign is negative. Electrocardiogram shows sinus rhythm with no acute ST segment or T wave changes. The physician decides to initiate a trial of omeprazole to treat the patient’s gastroesophageal reflux disease. How can the physician most effectively assure that this patient will adhere to the medication regimen?
Q3
A 56-year-old man presents to the family medicine office since he has been having difficulty keeping his blood pressure under control for the past month.

Question 1: A 57-year-old woman with type 2 diabetes mellitus comes to the physician for a follow-up examination. She previously had been compliant with her diet and medication but has had a 5-kg (11-lb) weight gain since the last visit 6 months ago. She reports that she often misses doses of her metformin. Her hemoglobin A1c is 9.8%. Which of the following is the most appropriate course of action?
A. Add glyburide to the medication regimen
B. Stop metformin and begin an insulin regimen
C. Schedule more frequent follow-up visits
D. Refer the patient to an endocrinologist
E. Refer the patient to a dietician (Correct Answer)
Explanation: ***Refer the patient to a dietician***
- The patient has **non-compliance with both diet and medication**, along with significant weight gain (5 kg) and severely uncontrolled diabetes (HbA1c 9.8%). A dietician can provide structured education on **nutrition management**, help address barriers to lifestyle adherence, and support weight management.
- Dietician referral is a **concrete, actionable intervention** that directly addresses multiple issues: the stated diet non-compliance, weight gain, and provides diabetes self-management education that can improve overall medication adherence.
- This intervention provides **professional support** beyond what can be achieved in brief physician visits and is appropriate before escalating to more complex medication regimens.
*Schedule more frequent follow-up visits*
- While increased monitoring may seem reasonable, this is a **passive approach** that doesn't provide the patient with concrete tools or resources to address her diet non-compliance and weight gain.
- With an HbA1c of 9.8%, simply watching and waiting with more frequent visits is insufficient; **active intervention** is needed to address the underlying behavioral and lifestyle issues.
- More frequent visits alone don't provide the structured education and support this patient needs.
*Add glyburide to the medication regimen*
- Adding a **sulfonylurea** like glyburide would likely worsen the patient's weight gain, as these drugs stimulate insulin release and commonly cause weight gain of 2-3 kg.
- Before adding medications, addressing the **underlying adherence issues** with current therapy is more appropriate, as medication intensification in a non-adherent patient is unlikely to be effective.
- Glyburide also carries a higher risk of **hypoglycemia** compared to metformin.
*Stop metformin and begin an insulin regimen*
- Starting insulin without first addressing **medication adherence** and lifestyle factors is premature, especially when the patient is already struggling with a simpler oral medication regimen.
- Insulin initiation requires intensive patient education, frequent glucose monitoring, and excellent self-management skills, making it particularly challenging for a patient with documented **adherence difficulties**.
- Before escalating to insulin, interventions targeting diet, lifestyle, and adherence should be attempted.
*Refer the patient to an endocrinologist*
- Endocrinology referral is typically reserved for **complex diabetes cases** with multiple complications, failure of optimal primary care management, or need for advanced therapies.
- The primary issue here is **non-compliance with basic management**, which can and should be addressed in primary care with appropriate support services (dietician, diabetes educator).
- Referral to an endocrinologist doesn't address the fundamental adherence and lifestyle issues this patient faces.
Question 2: A 34-year-old man presents to the local clinic with a 2 month history of midsternal chest pain following meals. He has a past medical history of hypertension. The patient takes lisinopril daily. He drinks 4–5 cans of 12 ounce beer daily, and chews 2 tins of smokeless tobacco every day. The vital signs are currently stable. Physical examination shows a patient who is alert and oriented to person, place, and time. Palpation of the epigastric region elicits mild tenderness. Percussion is normoresonant in all 4 quadrants. Murphy’s sign is negative. Electrocardiogram shows sinus rhythm with no acute ST segment or T wave changes. The physician decides to initiate a trial of omeprazole to treat the patient’s gastroesophageal reflux disease. How can the physician most effectively assure that this patient will adhere to the medication regimen?
A. Instruct the patient to purchase a weekly pill organizer
B. Have the patient repeat back to the physician the name of the medication, dosage, and frequency (Correct Answer)
C. Provide the patient with details of the medication on a print-out
D. Contact the pharmacist because they can explain the details more thoroughly
E. Tell the patient to write the medication name, dosage, and frequency on their calendar at home
Explanation: ***Have the patient repeat back to the physician the name of the medication, dosage, and frequency***
- The **"teach-back" method** is an effective way to confirm patient understanding and improve adherence by having the patient restate information in their own words.
- This method allows the physician to identify and clarify any misunderstandings immediately, ensuring the patient comprehends the **medication regimen**.
*Instruct the patient to purchase a weekly pill organizer*
- While a **pill organizer** can be helpful for medication organization, simply telling the patient to buy one does not guarantee they will understand or consistently use it.
- It does not address the fundamental issue of ensuring the patient fully comprehends the **medication instructions** and its importance.
*Provide the patient with details of the medication on a print-out*
- A print-out provides information, but merely giving a patient a **document** does not confirm they have read, understood, or retained the information.
- Many patients may not read or fully comprehend written materials, making it less effective than active engagement methods like **teach-back**.
*Contact the pharmacist because they can explain the details more thoroughly*
- Pharmacists play a crucial role in medication education, but delegating the primary explanation entirely removes the physician's opportunity to assess the patient's immediate understanding and address concerns directly.
- The **physician-patient interaction** is a key moment for establishing a shared understanding of the treatment plan.
*Tell the patient to write the medication name, dosage, and frequency on their calendar at home*
- This method relies on the patient's ability and willingness to *independently* record and recall information, which may not be sufficient for comprehensive understanding or adherence.
- It does not provide an immediate feedback loop for the physician to assess the patient's comprehension of the **treatment plan**.
Question 3: A 56-year-old man presents to the family medicine office since he has been having difficulty keeping his blood pressure under control for the past month. He has a significant medical history of hypertension, coronary artery disease, and diabetes mellitus. He has a prescription for losartan, atenolol, and metformin. The blood pressure is 178/100 mm Hg, the heart rate is 92/min, and the respiratory rate is 16/min. The physical examination is positive for a grade II holosystolic murmur at the left sternal border. He also has diminished sensation in his toes. Which of the following statements is the most effective means of communication between the doctor and the patient?
A. “What is causing your blood pressure to be elevated?” (Correct Answer)
B. “Have you been taking your medications as prescribed?”
C. “Would you like us to consider trying a different medication for your blood pressure?”
D. “You are taking your medications as prescribed, aren’t you?”
E. “Why are you not taking your medication?”
Explanation: ***“What is causing your blood pressure to be elevated?”***
- This is an **open-ended question** that encourages the patient to share their perspective, concerns, and potential reasons for the elevated blood pressure, fostering a **patient-centered approach**.
- It allows the physician to understand the patient's individual circumstances, medication adherence, lifestyle factors, or other contributing issues without being judgmental or leading.
*“Have you been taking your medications as prescribed?”*
- This is a **closed-ended question** that primarily elicits a "yes" or "no" answer, providing limited insight into the patient's actual adherence and the underlying reasons for non-adherence.
- While important, phrasing it this way might make the patient feel interrogated or judged, potentially hindering honest communication.
*“Would you like us to consider trying a different medication for your blood pressure?”*
- This question prematurely jumps to a solution without fully understanding the cause of the elevated blood pressure and the patient's perspective.
- It bypasses the crucial step of investigating potential reasons for poor blood pressure control, which could include non-adherence, lifestyle factors, or secondary hypertension, rather than necessarily a medication efficacy issue.
*“You are taking your medications as prescribed, aren’t you?”*
- This is a **leading question** that implies an expectation and can make the patient feel pressured to answer affirmatively, even if they are not consistently taking their medication.
- Such phrasing can create a defensive environment and discourage the patient from openly discussing adherence challenges.
*“Why are you not taking your medication?”*
- This is a **direct and accusatory question** that implies blame and can immediately put the patient on the defensive, making them less likely to be honest or forthcoming about their medication habits.
- It fails to create a supportive or collaborative atmosphere, which is essential for effective patient-physician communication.
Question 4: A 37-year-old man presents to his primary care physician because he has been experiencing episodes where he wakes up at night gasping for breath. His past medical history is significant for morbid obesity as well as hypertension for which he takes lisinopril. He is diagnosed with sleep apnea and prescribed a continuous positive airway pressure apparatus. In addition, the physician discusses making lifestyle and behavioral changes such as dietary modifications and exercise. The patient agrees to attempt these behavioral changes. Which of the following is most likely to result in improving patient adherence to this plan?
A. Refer the patient to a peer support group addressing lifestyle changes
B. Ask the patient to bring a family member to next appointment
C. Provide follow-up appointments to assess progress in attaining goals (Correct Answer)
D. Provide appropriate publications for the patient's educational level
E. Inform the patient of the health consequences of not intervening
Explanation: ***Provide follow-up appointments to assess progress in attaining goals***
- **Regular follow-up appointments** provide accountability and opportunities to discuss progress, troubleshoot challenges, and reinforce motivation for lifestyle changes
- This approach fosters a **patient-centered relationship** where the physician actively participates in the patient's journey, increasing adherence
- Evidence supports that scheduled follow-up is one of the most effective interventions for improving adherence to chronic disease management plans
*Refer the patient to a peer support group addressing lifestyle changes*
- While peer support can be beneficial for some patients, it is **not universally effective** and might not be suitable for all patients, especially as a primary strategy for adherence
- The effectiveness of such groups varies widely based on the patient's personality and group dynamics, potentially leading to **inconsistent adherence**
*Ask the patient to bring a family member to next appointment*
- Involving family can be supportive, but it may not always be appropriate or desired by the patient and doesn't directly address the patient's individual motivation or challenges
- While family support can enhance adherence, this approach is supplementary rather than primary in effectiveness
*Provide appropriate publications for the patient's educational level*
- Providing educational materials is a good initial step, but information alone is often **insufficient to sustain long-term behavioral changes**
- Without active follow-up and personalized guidance, written materials can be easily forgotten or not fully implemented into daily life
*Inform the patient of the health consequences of not intervening*
- While explaining risks is crucial for informed consent and awareness, relying solely on **fear-based motivation** often has limited long-term effectiveness in promoting sustained behavioral change
- Patients are often aware of potential negative consequences, but this knowledge alone does not provide the practical support or strategies needed for adherence
Question 5: In a randomized controlled trial studying a new treatment, the primary endpoint (mortality) occurred in 14.4% of the treatment group and 16.7% of the control group. Which of the following represents the number of patients needed to treat to save one life, based on the primary endpoint?
A. 1/(0.144 - 0.167)
B. 1/(0.167 - 0.144) (Correct Answer)
C. 1/(0.300 - 0.267)
D. 1/(0.267 - 0.300)
E. 1/(0.136 - 0.118)
Explanation: ***1/(0.167 - 0.144)***
- The **Number Needed to Treat (NNT)** is calculated as **1 / Absolute Risk Reduction (ARR)**.
- The **Absolute Risk Reduction (ARR)** is the difference between the event rate in the control group (16.7%) and the event rate in the treatment group (14.4%), which is **0.167 - 0.144**.
*1/(0.144 - 0.167)*
- This calculation represents 1 divided by the **Absolute Risk Increase**, which would be relevant if the treatment increased mortality.
- The **NNT should always be a positive value**, indicating the number of patients to treat to prevent one adverse event.
*1/(0.300 - 0.267)*
- This option uses arbitrary numbers (0.300 and 0.267) that do not correspond to the given **mortality rates** in the problem.
- It does not reflect the correct calculation for **absolute risk reduction** based on the provided data.
*1/(0.267 - 0.300)*
- This option also uses arbitrary numbers not derived from the problem's data, and it would result in a **negative value** for the denominator.
- The difference between event rates of 0.267 and 0.300 is not present in the given information for this study.
*1/(0.136 - 0.118)*
- This calculation uses arbitrary numbers (0.136 and 0.118) that are not consistent with the reported **mortality rates** of 14.4% and 16.7%.
- These values do not represent the **Absolute Risk Reduction** required for calculating NNT in this specific scenario.
Question 6: A 38-year-old woman comes to the physician for the first time because of a 2-year history of lower back pain and fatigue. She also says that she occasionally feels out of breath. Her symptoms are not associated with physical activity. She has seen multiple physicians over the past year. Extensive workup including blood and urine tests, abdominal ultrasound, MRI of the back, and cardiac stress testing have shown no abnormalities. The patient asks for a medication to alleviate her symptoms. Which of the following is the most appropriate response by the physician?
A. I would like to refer you to a psychiatric specialist to start behavioral psychotherapy.
B. Your symptoms are suggestive of a condition called somatic symptom disorder.
C. I would like to investigate your shortness of breath by performing coronary artery catheterization.
D. Your desire for pain medication is suggestive of a medication dependence disorder.
E. I would like to assess your symptoms causing you the most distress and schedule monthly follow-up appointments. (Correct Answer)
Explanation: ***"I would like to assess your symptoms causing you the most distress and schedule monthly follow-up appointments."***
- This response demonstrates **empathy** and a commitment to ongoing care, which is crucial for patients with **somatic symptoms** who often feel dismissed.
- Establishing a consistent relationship with a primary care physician can help manage chronic, unexplained symptoms and build **trust**, potentially reducing the need for extensive, often fruitless, investigations.
*"Your desire for pain medication is suggestive of a medication dependence disorder."*
- This statement is **judgmental** and incorrect, as the patient has not shown any signs of drug-seeking behavior beyond requesting medication for pain.
- It would likely damage the **doctor-patient relationship** and discourage the patient from seeking further help from this physician.
*"I would like to refer you to a psychiatric specialist to start behavioral psychotherapy."*
- While psychotherapy may be beneficial, immediately referring to a **psychologist** without first validating the patient's physical symptoms can make them feel dismissed.
- It's often more effective to integrate mental health support after a continued period of medical evaluation and relationship building.
*"Your symptoms are suggestive of a condition called somatic symptom disorder."*
- While the patient's symptoms are consistent with **somatic symptom disorder**, directly labeling the condition at the initial interaction might be perceived as diagnostic and **invalidating** to the patient, who believes their symptoms are purely physical.
- A more gradual approach, focusing on symptom management and observation, is usually preferred before introducing a psychiatric diagnosis.
*"I would like to investigate your shortness of breath by performing coronary artery catheterization."*
- The patient has already undergone an extensive cardiac stress test with **no abnormalities**, making an invasive procedure like catheterization unnecessary and potentially harmful.
- This approach ignores the previous negative workup and the chronic, unexplained nature of the symptoms, contributing to over-medicalization.
