Correct Answer: A

Rationale: Anisocoria refers to a condition where the pupils are of unequal size. Pathologic causes of anisocoria can include conditions such as Horner's syndrome. Horner's syndrome is a rare disorder caused by damage to the sympathetic nerves of the face and eye. Symptoms can include a constricted pupil (miosis), drooping of the upper eyelid (ptosis), and decreased sweating in the affected area. This results in anisocoria, where the affected pupil is smaller than the unaffected pupil. Other options listed (B-D) do not typically lead to pathologic anisocoria.

Correct Answer: D

Rationale: Since the patient, Susanne, has been experiencing headaches, muscle aches, and fatigue for the last 2 months, and a thorough history, examination, and laboratory workup have not revealed a definitive cause, the next step would be to screen for depression. Depression can present with physical symptoms such as headaches, muscle aches, and fatigue. It is important to consider mental health factors that could be contributing to Susanne's symptoms before proceeding with further referrals to specialists. Screening for depression would help in determining if psychological factors are playing a role in her physical symptoms.

Correct Answer: D

Rationale: The correct order of priority for the problem list in this case would be chest pain, headaches, arthritis, and war injury pain. Chest pain should always be a priority as it could indicate a serious or life-threatening condition such as a heart attack. Headaches, while important, are less urgent than chest pain. Arthritis can generally be managed without immediate intervention, making it a lower priority. Finally, the pain from the old war injury, while significant, is not as urgent as the other complaints.

Correct Answer: C

Rationale: The presentation of multiple small, blood-red, raised lesions over the anterior chest and abdomen in a middle-aged man raises concern for a condition known as cherry angiomas. Cherry angiomas are common benign vascular growths often seen in middle-aged and older individuals. They are typically asymptomatic and do not require treatment unless they are bothersome to the patient cosmetically.

Correct Answer: D

Rationale: Finding a bounding carotid pulse suggests a wide pulse pressure, which can be associated with aortic insufficiency. Aortic insufficiency (also known as aortic regurgitation) is characterized by the backflow of blood from the aorta into the left ventricle during diastole due to incomplete closure of the aortic valve. This results in increased stroke volume and left ventricular pressure, leading to widened pulse pressure and a bounding arterial pulse. Therefore, when a bounding carotid pulse is detected in a patient, it is important to search for signs and symptoms of aortic insufficiency, such as a diastolic murmur heard best at the left sternal border and radiating to the neck.
