Correct Answer: D

Rationale: The patient's presentation of tenderness in the left upper quadrant and epigastric area, along with normal bowel sounds, is suggestive of acute pancreatitis. This condition typically presents with severe, steady epigastric pain that may radiate to the back or left upper quadrant. Patients may also have tenderness on physical examination in these areas. Acute pancreatitis is commonly associated with risk factors such as gallstones or excessive alcohol consumption.

Correct Answer: B

Rationale: The scenario described suggests that Ray experiences pain only when actively lifting his arm over his head, which indicates the issue is likely originating from structures outside of the joint itself. When the shoulder is moved passively (moved by an external force), there is full range of motion without pain, suggesting that the limitation and pain occur due to muscles, tendons, or ligaments surrounding the joint rather than within the joint itself. In this case, the joint disease is likely to be extra-articular, involving structures such as muscles or tendons rather than being articular in nature.

Correct Answer: D

Rationale: The most likely abnormality of the scrotum that the patient has is a varicocele. This is indicated by the presence of a "bag of worms" feeling upon palpation of the right scrotum through the inguinal ring. Varicoceles are enlarged, twisted veins in the scrotum, similar to varicose veins that occur in the legs. They are more common on the left side, but can occur on the right side as well.

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: 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.
