A 26-year-old violinist comes to your clinic, complaining of anxiety. He is a first chair violinist in the local symphony orchestra and has started having symptoms during performances, such as sweating, shaking, and hyperventilating. It has gotten so bad that he has thought about giving up his first chair status so he does not have to play the solo during one of the movements. He says that he never has these symptoms during rehearsals or when he is practicing. He denies having any of these symptoms at any other time. His past medical history is unremarkable. He denies any tobacco use, drug use, or alcohol abuse. His parents are both healthy. On examination you see a young man who appears worried. His vital signs and physical examination are unremarkable. What type of anxiety disorder best describes his situation?

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: C

Rationale: The presence of new flat red and purple lesions that are tender on the ulnar aspect of Ms. Whiting's forearms raises concerns and warrants further investigation. Since she did not mention them, it is important to ask how she acquired them to gather more information. This will help determine the cause of the lesions and provide clues to potential underlying conditions or recent activities that could be related to their development. It is important not to dismiss these lesions as old without proper evaluation, as they could indicate a recent injury, infection, or other medical issues that may require attention.

Correct Answer: D

Rationale: The described findings of a triangular thickening of the bulbar conjunctiva across the outer surface of the cornea are characteristic of a pterygium. A pterygium is a benign growth of conjunctival tissue that extends onto the cornea. It is often associated with chronic exposure to ultraviolet light and typically occurs on the nasal side of the eye. Pterygiums are usually asymptomatic but can cause irritation, redness, and foreign body sensation in some cases. Surgical removal may be considered if the pterygium causes significant symptoms or affects vision.

Correct Answer: C

Rationale: A right homonymous hemianopsia refers to a visual field defect in which the patient is unable to see objects in the right half of the visual field in both eyes. In the case described, the stroke patient is unable to see your fingers on his entire right side with either eye covered, which is consistent with a right homonymous hemianopsia. This type of visual field defect typically occurs as a result of damage to the optic tract or optic radiation on one side of the brain, which affects the processing of visual information from the opposite visual field. It is important to note that bitemporal hemianopsia, right temporal hemianopsia, and binasal hemianopsia involve different patterns of visual field loss and are not fitting descriptions for the presented scenario.

Correct Answer: D

Rationale: The patient's symptoms point towards pneumonia. Pneumonia is characterized by infection and inflammation in the lung tissue, leading to symptoms such as decreased air movement, crackles on auscultation, dullness on percussion, increased fremitus on palpation, and abnormal breath sounds like egophony and whispered pectoriloquy. These findings are consistent with consolidation of the lung, which occurs in pneumonia as a result of fluid, inflammatory cells, and tissue debris filling the alveoli. The presence of nasal turbinates edema indicates a possible upper respiratory tract infection that may have preceded the development of pneumonia. Spontaneous pneumothorax would typically present with sudden-onset chest pain and dyspnea but would not typically cause findings of lung consolidation. Chronic obstructive pulmonary disease (COPD) and asthma are characterized by different patterns of lung damage and symptoms, such as chronic inflammation, airflow obstruction, and hyper
