An elderly woman with dementia is brought in by her daughter for a "rectal mass." On examination you notice a moist pink mass protruding from the anus, which is nontender. It is soft and does not have any associated bleeding. Which of the following is most likely?

Correct Answer: A

Rationale: Rectal prolapse occurs when the rectum protrudes through the anus. It typically appears as a moist, pink mass that protrudes outside the body. The prolapse is usually painless and can be seen and felt by the patient or the examiner. It is commonly seen in elderly individuals, especially women, and those with conditions like chronic constipation, pelvic floor weakness, or dementia. On the other hand, external hemorrhoids are swollen veins located around the anus, usually painful and may cause bleeding. Perianal fistula is an abnormal tunnel-like connection between the skin near the anus and the rectum, which can cause pain and discharge. Prolapsed internal hemorrhoids are internal hemorrhoids that have descended outside the anal canal and may require manual reduction. Given the symptoms described in the scenario - a moist pink mass protruding from the anus that is nontender and soft without bleeding - the most likely diagnosis is rectal prol

Correct Answer: B

Rationale: Tympany is the percussion note you would obtain over the gastric bubble. Tympany is a drum-like sound and is typically heard over air-filled structures in the body, such as the stomach, intestines, and lungs. When percussing over the gastric bubble (air-filled stomach), you would expect to hear a tympanic note due to the presence of air in the stomach creating resonance. Resonance (choice A) is a low-pitched, hollow sound heard over normal lung tissue. Hyperresonance (choice C) is an abnormally loud, booming sound heard over hyperinflated lungs, as in conditions like emphysema. Flatness (choice D) is a dull sound heard over solid organs or areas of tissue consolidation, such as over the liver or a pleural effusion.

Correct Answer: D

Rationale: Following a severe rotator cuff tear, it typically takes around 2-3 months for muscular atrophy to develop with increased prominence of the scapular spine. This is due to disuse of the affected shoulder muscles leading to muscle wasting and changes in the bony structures around the shoulder blade. Over time, the lack of muscle activity causes the shoulder blade to become more prominent and noticeable, which can result in altered sensations during activities like hugging. The gradual onset of these changes aligns with the timeline provided in the question, where the wife started to feel discomfort in her husband's left shoulder blade after the recent severe rotator cuff tear.

Correct Answer: C

Rationale: Shortness of breath is commonly associated with issues related to the heart and cardiovascular system. Conditions such as heart failure, coronary artery disease, or arrhythmias can lead to symptoms like shortness of breath. Therefore, the symptom of shortness of breath would be assigned to the cardiac anatomic region.

Correct Answer: B

Rationale: A sudden, painful unilateral loss of vision is a medical emergency that may be caused by central retinal artery occlusion. This condition occurs when the main artery supplying blood to the retina becomes blocked, leading to a sudden and severe reduction in blood flow to the eye. The lack of blood flow can cause irreversible damage to the retina, resulting in a significant loss of vision. Patients with central retinal artery occlusion typically present with sudden, painless, and severe vision loss in one eye. Immediate medical attention is crucial to try to restore blood flow and minimize potential permanent vision loss in these cases. Vitreous hemorrhage, macular degeneration, and optic neuritis do not typically present with sudden, painful unilateral loss of vision as seen in central retinal artery occlusion.

Correct Answer: B

Rationale: A varicocele is a common cause of a "bag of worms" feeling in the scrotum. It occurs due to the dilation of the veins within the spermatic cord, leading to a palpable mass above the testicle. Varicoceles are more commonly found on the left side due to the anatomy of the left testicular vein, which drains into the left renal vein at a right angle, making it more susceptible to increased pressure and dilation.

Correct Answer: C

Rationale: For a new patient with the chief complaint of "I am here to establish care," a comprehensive health history would be appropriate. In this scenario, since the patient is new to the healthcare provider, it is important to gather detailed information about the patient's past medical history, family history, social history, medications, allergies, and specific health concerns. This comprehensive health history will help the healthcare provider establish a baseline of the patient's overall health and identify any potential risk factors or underlying conditions that may impact future care and treatment decisions. Additionally, obtaining a thorough health history is essential in building a strong patient-provider relationship and providing patient-centered care.

Correct Answer: A

Rationale: The description provided fits the criteria for tension-type headache. Tension-type headaches are typically described as a mild to moderate, dull, band-like pressure or tightness around the head. They can last from minutes to days and are often triggered by stress, anxiety, poor posture, or prolonged computer use. The absence of symptoms like photophobia and nausea, along with the response to over-the-counter medication, further support the diagnosis of tension-type headache in this case. Other headache types such as migraines or cluster headaches usually present with additional symptoms like nausea, photophobia, or tearing of the eye, which are not mentioned in this scenario. Analgesic rebound headaches typically occur in individuals who overuse pain medications, leading to worsening headaches when the medication wears off, but this patient's history does not suggest such misuse.

Correct Answer: A

Rationale: Intermittent claudication is a common symptom of peripheral vascular disease. It is characterized by muscle pain or cramping in the legs, usually in the calves, thighs, or buttocks, that occurs during physical activity such as walking and is relieved by rest. This symptom is due to inadequate blood flow to the muscles during exercise. It is important to assess for intermittent claudication in patients with risk factors such as smoking, diabetes, and hypertension, as it may indicate underlying peripheral arterial disease. The other symptoms listed (chest pressure with exertion, shortness of breath, knee pain) are not typically associated with peripheral vascular disease.
