Paraphimosis and phimosis US Medical PG Practice Questions and MCQs
Practice US Medical PG questions for Paraphimosis and phimosis. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Paraphimosis and phimosis US Medical PG Question 1: A 45-year-old man presents with a long history of ulcers on the bottom of his feet. He recalls having a similar looking ulcer on the side of his penis when he was 19 years old for which he never sought treatment. The patient denies any fever, chills, or constitutional symptoms. He reports multiple sexual partners and a very promiscuous sexual history. He has also traveled extensively as a writer since he was 19. The patient is afebrile, and his vital signs are within normal limits. A rapid plasma reagin (RPR) test is positive, and the result of a Treponema pallidum particle agglutination (TP-PA) is pending. Which of the following findings would most likely be present in this patient?
- A. Hyperreflexia
- B. Memory loss
- C. Wide-based gait with a low step
- D. Positive Romberg's sign (Correct Answer)
- E. Agraphesthesia
Paraphimosis and phimosis Explanation: ***Positive Romberg's sign***
- The patient's history of untreated penile ulcers at age 19, extensive sexual history, and positive RPR strongly suggest **late-stage syphilis** [3].
- A positive Romberg's sign indicates **sensory ataxia**, which is a classic finding in **tabes dorsalis**, a manifestation of neurosyphilis involving degeneration of the dorsal columns and dorsal roots of the spinal cord [1].
*Hyperreflexia*
- **Hyperreflexia** is typically seen in **upper motor neuron lesions**, while tabes dorsalis primarily affects the **sensory pathways** (dorsal columns), leading to sensory deficits rather than motor spasticity.
- In some neurosyphilis cases, **hyporeflexia or areflexia** may be observed due to damage to the dorsal roots.
*Memory loss*
- **Memory loss** can occur in neurosyphilis, particularly in conditions like **general paresis**, which is a form of neurosyphilis affecting the cerebral cortex [3].
- However, the symptom of **foot ulcers** points more directly to sensory neuropathy, making **ataxia** (and thus Romberg's sign) a more likely direct neurological finding.
*Wide-based gait with a low step*
- A **wide-based gait with a high stepping (steppage) gait** is characteristic of **foot drop** or **motor neuropathy**, which is less typical for tabes dorsalis.
- A **wide-based gait** can occur in tabes dorsalis due to **sensory ataxia** [2], but the "low step" component is less specific compared to the clear indication of sensory loss by Romberg's sign.
*Agraphesthesia*
- **Agraphesthesia** (inability to recognize writing on the skin) is a sign of **parietal lobe dysfunction** or severe sensory pathway damage.
- While neurosyphilis can affect various parts of the CNS, **tabes dorsalis** primarily causes problems with proprioception and vibratory sense, leading to ataxia and a positive Romberg's sign.
Paraphimosis and phimosis US Medical PG Question 2: A 17-year-old male, accompanied by his uncle, presents to a doctor with his arm in a sling. There is blood dripping down his shirt. He pleads with the physician to not report this injury to authorities, offering to pay extra for his visit, as he is afraid of retaliation from his rival gang. The physician examines the wound, which appears to be a stabbing injury to his left anterior deltoid. This case study in medical ethics asks: How should the physician best handle this patient's request?
- A. Maintain confidentiality, as reporting stab wounds is not required
- B. Breach confidentiality and discuss the injury with the uncle
- C. Breach confidentiality and report the stab wound to the police (Correct Answer)
- D. Maintain confidentiality and schedule a follow-up visit with the patient
- E. Maintain confidentiality, as retaliation may result in greater harm to the patient
Paraphimosis and phimosis Explanation: ***Breach confidentiality and report the stab wound to the police***
- Physicians in the United States have a **mandatory reporting obligation** for injuries resulting from violent crimes, including stab wounds, regardless of the patient's wishes.
- **State laws** require reporting of suspected criminal activity involving weapons, and physicians are **legally protected** from liability when making good-faith mandatory reports.
- While the principle of **non-maleficence** is important, **legal duties** take precedence, and physicians cannot selectively choose when to comply with mandatory reporting laws based on patient circumstances.
- The physician should explain to the patient that reporting is required by law, provide compassionate care, and potentially connect the patient with **social services** or **law enforcement victim support** to address safety concerns.
*Maintain confidentiality, as retaliation may result in greater harm to the patient*
- While concern for patient safety is understandable, **mandatory reporting laws do not have exceptions** for fear of retaliation.
- Physicians who fail to report may face **professional discipline**, **civil liability**, and potentially **criminal penalties** depending on jurisdiction.
- The proper approach is to report as required while simultaneously working to ensure patient safety through appropriate **social work intervention** and **victim protection resources**.
*Maintain confidentiality and schedule a follow-up visit with the patient*
- Simply scheduling follow-up care while failing to report violates **mandatory reporting statutes** for violent injuries.
- This approach ignores the physician's **legal obligation** and could result in professional consequences.
- Follow-up care should be provided **in addition to**, not instead of, mandatory reporting.
*Maintain confidentiality, as reporting stab wounds is not required*
- This is **factually incorrect**; virtually all U.S. jurisdictions require reporting of injuries from violent crimes, particularly those involving weapons.
- Failure to report based on this misunderstanding could lead to **licensure sanctions** and legal liability.
*Breach confidentiality and discuss the injury with the uncle*
- The 17-year-old patient is a **minor**, but discussing details with the uncle without explicit consent or confirmed guardianship status is inappropriate.
- The uncle's presence does not automatically grant him **HIPAA authorization** to receive protected health information.
- The correct action is to report to **appropriate authorities** (police), not to involve family members without proper consent or legal authority.
Paraphimosis and phimosis US Medical PG Question 3: A 23-year-old G1P0 female presents to her OB/GYN for her routine 36-week visit. Her current complaints include increased fatigue at the end of the day, and edema in her ankles. The patient’s physical examination is unremarkable except for inguinal adenopathy. Upon pelvic examination for cervical changes, the OB/GYN notices a vaginal chancre. The patient states that it is not painful when touched. Which of the following is the most likely diagnosis?
- A. Secondary syphilis
- B. Cardiovascular syphilis
- C. Primary syphilis (Correct Answer)
- D. Gummatous syphilis
- E. Neurosyphilis
Paraphimosis and phimosis Explanation: ***Primary syphilis***
- A **painless chancre** is the hallmark lesion of primary syphilis, which develops at the site of initial inoculation.
- While fatigue and edema are common in pregnancy, the presence of a **painless vaginal chancre** and **inguinal adenopathy** is highly indicative of primary syphilis.
*Secondary syphilis*
- This stage is characterized by a **disseminated skin rash** (often involving palms and soles), **condyloma lata**, and generalized lymphadenopathy, not a solitary chancre.
- Symptoms usually appear several weeks or months after the chancre of primary syphilis has healed.
*Cardiovascular syphilis*
- This is a form of **tertiary syphilis** that affects the heart and great vessels, typically resulting in **aortitis**, aneurysms, or aortic regurgitation.
- It develops years to decades after the initial infection and would not present with a chancre.
*Gummatous syphilis*
- This is another manifestation of **tertiary syphilis**, characterized by the formation of **gummas**—soft, non-cancerous granulomas that can affect any organ.
- Like cardiovascular syphilis, it occurs many years after initial infection and does not involve a primary chancre.
*Neurosyphilis*
- This involves the **central nervous system** and can occur at any stage of syphilis, but is usually a late complication.
- Symptoms vary widely but include **meningitis**, strokes, or psychiatric manifestations, none of which are consistent with a chancre or the acute presentation described.
Paraphimosis and phimosis US Medical PG Question 4: A 22-year-old man comes to the physician because of an ulcer on his penis for 12 days. The ulcer is painful and draining yellow purulent material. He returned from a study abroad trip to India 3 months ago. His immunizations are up-to-date. He is sexually active with one female partner and uses condoms inconsistently. He appears uncomfortable. His temperature is 37.2°C (99.0°F), pulse is 94/min, and blood pressure is 120/80 mm Hg. Examination shows tender inguinal lymphadenopathy. There is a 2-cm ulcer with a necrotic base proximal to the glans of the penis. Which of the following is the most likely causal organism?
- A. Klebsiella granulomatis
- B. Haemophilus ducreyi (Correct Answer)
- C. Herpes simplex virus 2
- D. Treponema pallidum
- E. Chlamydia trachomatis
Paraphimosis and phimosis Explanation: ***Haemophilus ducreyi***
- The presentation of a **single, painful penile ulcer** with a **necrotic base** and **tender inguinal lymphadenopathy** is classic for **chancroid**,
- This condition is caused by **Haemophilus ducreyi**, and the patient's recent travel to India, where chancroid is endemic, increases the likelihood of this diagnosis.
*Klebsiella granulomatis*
- This bacterium causes **granuloma inguinale (donovanosis)**, which typically presents with **painless, beefy-red ulcers** that bleed easily,
- The ulcer described in the patient is **painful** and has a **necrotic base**, which is inconsistent with donovanosis.
*Herpes simplex virus 2*
- **Herpes simplex virus (HSV-2)** typically causes **multiple, painful vesicular lesions** that rupture to form shallow ulcers, often accompanied by systemic symptoms like fever and malaise.
- The patient describes a **single, large ulcer** with a necrotic base, which is not characteristic of herpetic lesions.
*Treponema pallidum*
- **Treponema pallidum** causes **syphilis**, which presents as a **painless chancre** with a clean base and firm, non-tender lymphadenopathy in its primary stage.
- The patient's ulcer is explicitly described as **painful** and draining **purulent material**, ruling out a syphilitic chancre.
*Chlamydia trachomatis*
- Certain serovars of **Chlamydia trachomatis** cause **lymphogranuloma venereum (LGV)**, which initially presents as a transient, **painless papule or ulcer** that often goes unnoticed, followed by significant, painful inguinal lymphadenopathy (buboes).
- While LGV involves painful lymphadenopathy, the initial ulcer is typically small and unnoticed, and the described ulcer is large, painful, and has a necrotic base, which is not characteristic of LGV.
Paraphimosis and phimosis US Medical PG Question 5: A previously healthy 25-year-old male comes to his primary care physician with a painless solitary lesion on his penis that developed 4 days ago. He has not experienced anything like this before. He is currently sexually active with multiple partners and uses condoms inconsistently. His temperature is 37.0°C (98.7°F), pulse is 67/min, respirations are 17/min, and blood pressure is 110/70 mm Hg. Genitourinary examination shows a shallow, nontender, firm ulcer with a smooth base along the shaft of the penis. There is nontender inguinal adenopathy bilaterally. Which of the following is the most appropriate next step to confirm the diagnosis?
- A. Rapid plasma reagin
- B. Urine polymerase chain reaction
- C. Fluorescent treponemal antibody absorption test
- D. Swab culture
- E. Dark-field microscopy (Correct Answer)
Paraphimosis and phimosis Explanation: ***Dark-field microscopy***
- The patient's presentation with a **painless, firm, shallow ulcer** (chancre) on the penis and **bilateral nontender inguinal adenopathy**, in the context of high-risk sexual behavior, is highly suggestive of **primary syphilis**.
- **Dark-field microscopy** of exudate from the chancre allows for direct visualization of motile *Treponema pallidum* spirochetes and is the definitive method for confirming primary syphilis, especially before serological tests become positive.
*Rapid plasma reagin*
- **RPR is a nontreponemal serological test** used for screening syphilis. It typically becomes reactive 1-3 weeks after the appearance of a chancre.
- Given that the lesion developed only 4 days ago, the RPR might still be **negative due to the lag phase** before antibody production.
*Urine polymerase chain reaction*
- A **urine PCR** is primarily used to detect nucleic acids of infectious agents, commonly for conditions like chlamydia or gonorrhea.
- It is **not the standard or most accurate method** for diagnosing syphilis, which is caused by a spirochete and typically diagnosed by direct visualization or serology.
*Fluorescent treponemal antibody absorption test*
- The **FTA-ABS is a treponemal-specific serological test** that usually becomes reactive earlier than non-treponemal tests (like RPR), but still typically weeks after infection.
- While sensitive, it is generally used as a **confirmatory test** for positive nontreponemal results or when clinical suspicion is high and nontreponemal tests are initially negative. It is not a direct detection method.
*Swab culture*
- **Swab culture** is used to grow bacteria for identification and susceptibility testing.
- *Treponema pallidum*, the causative agent of syphilis, **cannot be cultured on artificial media**, making swab culture an inappropriate diagnostic method for syphilis.
Paraphimosis and phimosis US Medical PG Question 6: A 54-year-old male carpenter accidentally amputated his right thumb while working in his workshop 30 minutes ago. He reports that he was cutting a piece of wood, and his hand became caught up in the machinery. He is calling the emergency physician for advice on how to transport his thumb and if it is necessary. Which of the following is the best information for this patient?
- A. Place thumb in cup of cold milk
- B. Wrap thumb in saline-moistened, sterile gauze and place in sterile bag (Correct Answer)
- C. Wrap thumb in sterile gauze and submerge in a cup of saline
- D. There is no need to save the thumb
- E. Place thumb directly into cooler of ice
Paraphimosis and phimosis Explanation: ***Wrap thumb in saline-moistened, sterile gauze and place in sterile bag***
- This method provides a **moist, sterile environment** for the amputated part, which is crucial for preserving tissue viability.
- The use of a sterile bag helps prevent contamination and allows the part to be placed inside a cooler without direct ice contact, preventing **frostbite**.
*Place thumb in cup of cold milk*
- While cold milk might offer some cooling, it is **not sterile** and could introduce bacteria, increasing the risk of infection.
- Milk's composition is **not ideal for cell preservation** compared to saline, which is more isotonic.
*Wrap thumb in sterile gauze and submerge in a cup of saline*
- Submerging the amputated part directly in saline, even with sterile gauze, can lead to **tissue maceration** due to overhydration.
- This method also makes it more difficult to prevent contamination during transportation if the cup is not sealed.
*There is no need to save the thumb*
- **Replantation surgery** is often possible and highly desirable for thumb amputations due to its critical functional role.
- Dismissing the amputated part would deprive the patient of a chance to restore function, especially given the short time since amputation.
*Place thumb directly into cooler of ice*
- Direct contact with ice can cause **frostbite** and **tissue damage**, compromising the viability of the amputated part.
- The preferred method is to keep the amputated part cool, but not frozen, usually by placing it in a sealed bag within an ice-filled container.
Paraphimosis and phimosis US Medical PG Question 7: A 40-year-old sailor is brought to a military treatment facility 20 minutes after being involved in a navy ship collision. He appears ill. He reports a sensation that he needs to urinate but is unable to void. His pulse is 140/min, respirations are 28/min, and blood pressure is 104/70 mm Hg. Pelvic examination shows ecchymoses over the scrotum and perineum. There is tenderness over the suprapubic region and blood at the urethral meatus. Digital rectal examination shows a high-riding prostate. Abdominal ultrasound shows a moderately distended bladder. X-rays of the pelvis show fractures of all four pubic rami. Which of the following is the most likely cause of this patient's symptoms?
- A. Tearing of the anterior urethra
- B. Rupture of the corpus cavernosum
- C. Tearing of the posterior urethra (Correct Answer)
- D. Tearing of the ureter
- E. Rupture of the bladder
Paraphimosis and phimosis Explanation: ***Tearing of the posterior urethra***
- The combination of **pelvic fractures**, **blood at the urethral meatus**, inability to void despite a sensation to do so, and a **high-riding prostate** are classic signs of posterior urethral injury.
- The posterior urethra, particularly the membranous portion, is vulnerable to shear forces and tearing during severe pelvic trauma.
*Tearing of the anterior urethra*
- Anterior urethral injuries are typically associated with a **straddle injury** or direct trauma to the perineum, not necessarily pelvic fractures.
- While blood at the meatus can occur, the **high-riding prostate** and extensive pelvic fractures point away from an isolated anterior injury.
*Rupture of the corpus cavernosum*
- This is usually a result of "penile fracture" during sexual intercourse and presents with sudden pain, detumescence, and a characteristic "eggplant" deformity, which are not described here.
- It does not explain the inability to void, high-riding prostate, or association with pelvic fractures.
*Tearing of the ureter*
- Ureteral injuries are typically associated with penetrating trauma or iatrogenic injury during surgery; they rarely occur with blunt pelvic trauma of this nature.
- Symptoms would include flank pain, hematuria, or urine leakage into the retroperitoneum, not significant urethral bleeding or a high-riding prostate.
*Rupture of the bladder*
- Bladder rupture can be intra- or extraperitoneal and is often associated with pelvic fractures. However, it typically causes gross hematuria and often free fluid in the peritoneum (intraperitoneal rupture) or extravasation into the space of Retzius (extraperitoneal rupture).
- While a distended bladder is noted, the presence of **blood at the urethral meatus** and a **high-riding prostate** strongly implicate urethral injury rather than primarily bladder rupture.
Paraphimosis and phimosis US Medical PG Question 8: A 28-year-old male presents to his primary care physician with complaints of intermittent abdominal pain and alternating bouts of constipation and diarrhea. His medical chart is not significant for any past medical problems or prior surgeries. He is not prescribed any current medications. Which of the following questions would be the most useful next question in eliciting further history from this patient?
- A. "Does the diarrhea typically precede the constipation, or vice-versa?"
- B. "Is the diarrhea foul-smelling?"
- C. "Please rate your abdominal pain on a scale of 1-10, with 10 being the worst pain of your life"
- D. "Are the symptoms worse in the morning or at night?"
- E. "Can you tell me more about the symptoms you have been experiencing?" (Correct Answer)
Paraphimosis and phimosis Explanation: ***Can you tell me more about the symptoms you have been experiencing?***
- This **open-ended question** encourages the patient to provide a **comprehensive narrative** of their symptoms, including details about onset, frequency, duration, alleviating/aggravating factors, and associated symptoms, which is crucial for diagnosis.
- In a patient presenting with vague, intermittent symptoms like alternating constipation and diarrhea, allowing them to elaborate freely can reveal important clues that might not be captured by more targeted questions.
*Does the diarrhea typically precede the constipation, or vice-versa?*
- While knowing the sequence of symptoms can be helpful in understanding the **pattern of bowel dysfunction**, it is a very specific question that might overlook other important aspects of the patient's experience.
- It prematurely narrows the focus without first obtaining a broad understanding of the patient's overall symptomatic picture.
*Is the diarrhea foul-smelling?*
- Foul-smelling diarrhea can indicate **malabsorption** or **bacterial overgrowth**, which are important to consider in some gastrointestinal conditions.
- However, this is a **specific symptom inquiry** that should follow a more general exploration of the patient's symptoms, as it may not be relevant if other crucial details are missed.
*Please rate your abdominal pain on a scale of 1-10, with 10 being the worst pain of your life*
- Quantifying pain intensity is useful for assessing the **severity of discomfort** and monitoring changes over time.
- However, for a patient with intermittent rather than acute, severe pain, understanding the **character, location, and triggers** of the pain is often more diagnostically valuable than just a numerical rating initially.
*Are the symptoms worse in the morning or at night?*
- Diurnal variation can be relevant in certain conditions, such as inflammatory bowel diseases where nocturnal symptoms might be more concerning, or functional disorders whose symptoms might be stress-related.
- This is another **specific question** that should come after gathering a more complete initial picture of the patient's symptoms to ensure no key information is overlooked.
Paraphimosis and phimosis US Medical PG Question 9: Three hours later, the patient is reassessed. Her right arm is put in an elevated position and physical examination of the extremity is performed. The examination reveals reduced capillary return and peripheral pallor. Pulse oximetry of her right index finger on room air shows an oxygen saturation of 84%. Which of the following is the most appropriate next step in management?
- A. Perform fasciotomy
- B. Obtain split-thickness skin graft
- C. Decrease rate of IV fluids
- D. Perform right upper extremity amputation
- E. Perform escharotomy (Correct Answer)
Paraphimosis and phimosis Explanation: ***Perform escharotomy***
- The patient's symptoms of **reduced capillary return**, **peripheral pallor**, and **low oxygen saturation** in the setting of an elevated arm indicate **compartment syndrome** due to circumferential burn-related edema.
- **Escharotomy** is the appropriate immediate intervention to relieve pressure and restore circulation in deep circumferential burns.
*Perform fasciotomy*
- **Fasciotomy** is indicated for compartment syndrome due to **non-burn-related trauma** or other causes, where the tight fascia is the primary constricting factor.
- In burns, the **tough, inelastic eschar** itself is usually the constricting element, requiring escharotomy.
*Obtain split-thickness skin graft*
- A **split-thickness skin graft** is a reconstructive procedure performed after the burn wound has been adequately debrided and the patient is stable.
- It is not an emergent intervention to address acute limb ischemia from compartment syndrome.
*Decrease rate of IV fluids*
- While excessive fluid resuscitation can contribute to edema, the immediate and critical issue is the **compromised circulation** due to the constricting eschar, not solely fluid overload.
- Reducing IV fluids would not rapidly reverse the existing limb ischemia and could potentially lead to **hypoperfusion** if the patient is already under-resuscitated.
*Perform right upper extremity amputation*
- **Amputation** is a last resort, considered only after all attempts to salvage the limb, including escharotomy, have failed and there is irreversible tissue necrosis.
- It is not the appropriate first-line response to acute compartment syndrome from burns.
Paraphimosis and phimosis US Medical PG Question 10: A 70-year-old man with metastatic castration-resistant prostate cancer presents to the emergency department with severe back pain, bilateral lower extremity weakness (3/5 strength), and urinary retention that started 8 hours ago. He has known bone metastases and his PSA has been rising despite androgen deprivation therapy. MRI spine shows an epidural mass at T10 with severe spinal cord compression and near-complete canal obliteration. He is neurologically intact above T10. Radiation oncology, neurosurgery, and medical oncology are consulted. Evaluate the optimal management approach.
- A. Corticosteroids, radiation therapy, and switch to next-line systemic therapy
- B. Stereotactic radiosurgery as single-modality treatment
- C. Emergent surgical decompression followed by radiation therapy (Correct Answer)
- D. Palliative care consultation and comfort measures only given metastatic disease
- E. High-dose corticosteroids and emergent radiation therapy alone
Paraphimosis and phimosis Explanation: ***Emergent surgical decompression followed by radiation therapy***
- For patients with **malignant spinal cord compression (MSCC)** and acute neurologic deficits lasting <48 hours, **decompressive surgery** followed by radiotherapy results in better ambulatory outcomes than radiation alone.
- This patient has a **single level of compression** (T10) and a reasonable functional status above the lesion, making him an ideal candidate for surgery to preserve **quality of life**.
*Corticosteroids, radiation therapy, and switch to next-line systemic therapy*
- While **systemic therapy** is important for managing metastatic disease, it does not address the acute **mechanical compression** currently threatening spinal cord viability.
- Postponing definitive mechanical decompression in favor of systemic treatment would likely result in **permanent paraplegia** given the severe canal obliteration.
*Stereotactic radiosurgery as single-modality treatment*
- **Stereotactic radiosurgery (SRS)** is effective for spinal metastases but is generally not the primary choice when there is **high-grade spinal cord compression** with an associated neurologic deficit.
- Surgery is needed first to provide immediate **mechanical decompression** and create a "separation" distance between the cord and the tumor for safer high-dose radiation.
*Palliative care consultation and comfort measures only given metastatic disease*
- Although the cancer is metastatic, preserving **ambulatory function** and bladder control is a priority for maintaining dignity and independence.
- **MSCC** is an oncologic emergency where intervention is indicated unless the patient's **life expectancy** is very short (typically <3 months), which is not clearly the case here.
*High-dose corticosteroids and emergent radiation therapy alone*
- Radiation therapy alone is typically reserved for patients who are not **surgical candidates**, have multisegmental disease, or have complete paralysis for >48 hours.
- **Direct decompressive surgery** is superior for restoring and maintaining the ability to walk in patients with acute, unstable neurologic symptoms from a **single-level mass**.
