Correct Answer: C

Rationale: The young violinist is experiencing symptoms of anxiety specifically related to performing in front of others, which is characteristic of social phobia (also known as social anxiety disorder). The symptoms occur only during performances, indicating the anxiety is triggered by social situations where he is the center of attention. His ability to perform without symptoms during rehearsals or practice sessions further supports the diagnosis of social phobia, as the anxiety is specifically related to public performance. In contrast, panic disorder is characterized by recurrent, unexpected panic attacks that are not situation-specific, and specific phobia involves an intense fear of a specific object or situation, neither of which fully match this patient's presentation. Generalized anxiety disorder involves excessive worry and anxiety about various aspects of life, which is not the main feature of this case.

Correct Answer: B

Rationale: Based on the description provided, the skin lesions are most consistent with seborrheic keratosis. Seborrheic keratoses are common non-cancerous (benign) growths of the skin that often appear as brown, black, or light tan growths with a waxy, stuck-on appearance. They can vary in color and may be round or oval, with a well-defined border. Seborrheic keratoses are typically asymptomatic and can be found on various parts of the body including the face, arms, and legs. The dry, hard scale covering the lesion is typical for seborrheic keratoses.

Correct Answer: B

Rationale: The information provided - "The patient had a stent placed in the left anterior descending artery (LAD)" - is related to a medical procedure, specifically a surgical intervention involving the placement of a stent in a coronary artery. This information falls under the category of surgeries because it describes a surgical treatment to address a cardiovascular issue. It does not pertain to adult illnesses, obstetrics/gynecology, or psychiatric conditions, making option B the most appropriate category for this information.

Correct Answer: C

Rationale: Family history of osteoporosis is a significant risk factor, as genetics play a key role in determining a person's risk for developing osteoporosis. Having a close relative, such as an aunt, with severe osteoporosis increases this woman's risk as there is a strong genetic component to the disease. Factors such as obesity (choice A), late menopause (choice B), and delayed menarche (choice D) do not directly increase the risk of osteoporosis, unlike having a familial history of the condition.

Correct Answer: C

Rationale: The most likely explanation for Mrs. Lenzo noticing a 4-pound weight gain over just 2 days is fluctuations in body fluid. Our body weight can fluctuate throughout the day due to factors such as hydration levels, sodium intake, and hormonal changes. It is not physically possible to gain 4 pounds of actual body mass (e.g., fat or muscle) in such a short period of time by overeating or wearing different clothing. Additionally, if Mrs. Lenzo's scale is very accurate as mentioned, it is less likely that the weight gain is due to instrument inaccuracy. Therefore, the most plausible reason for the sudden weight gain is fluctuations in body fluid retention.
