Correct Answer: D

Rationale: The correct answer is D: migraine headaches. The patient's symptoms of severe throbbing headache in the frontotemporal area, triggered by stress (studying for an exam), partially relieved by lying down, and family history of similar headaches are indicative of migraines. Migraines commonly present with these characteristics, often exacerbated by stress and have a genetic component. A: Hypertension does not typically present with throbbing headaches in a specific area or relief with lying down. B: Cluster headaches are characterized by severe, unilateral headaches around the eye area, not frontotemporal. C: Tension headaches usually present as dull, constant pressure-type headaches, not throbbing, and do not have the familial pattern described by the patient.

Correct Answer: A

Rationale: The correct answer is A: Weber. The Weber test has been found to yield unreliable data recently due to its subjectivity and inconsistency in interpretation. The test involves placing a vibrating tuning fork on the midline of the head to assess lateralization of sound. However, factors like bone conduction and individual perception can influence the results, leading to inaccuracies. Romberg test (B) evaluates balance, Whisper test (C) assesses hearing sensitivity, and Audiometer (D) measures hearing thresholds objectively. These tests are more reliable in providing accurate data compared to the Weber test.

Correct Answer: C

Rationale: The correct answer is C because shining a light across the pupil from the side allows for both direct (ipsilateral) and consensual (contralateral) pupillary constriction to be observed. This technique helps to assess the integrity of the cranial nerves involved in the pupillary light reflex (CN II and III). Direct constriction occurs in the eye exposed to the light, while consensual constriction occurs in the opposite eye. This comprehensive assessment ensures that both pupils are responding appropriately to light stimulation, providing a more accurate evaluation of the reflex. Choice A is incorrect because inspecting for pupillary constriction from directly in front may not adequately assess for consensual constriction in the opposite eye. Choice B is incorrect as asking the patient to follow the penlight in eight directions does not specifically target the pupillary light reflex. Choice D is incorrect as it focuses on accommodation rather than the pupillary light reflex.

Correct Answer: C

Rationale: The correct answer is C: Erythematous scaly patch with sharp margins in the sacral area. In patients with AIDS, this presentation is most likely indicative of a common opportunistic infection called tinea corporis. This fungal infection often presents as erythematous scaly patches with well-defined borders. The location in the sacral area is also common due to the warm and moist environment. Choice A, tinea capitis, is a fungal infection of the scalp and is not typically associated with AIDS. Choice B describes a presentation more indicative of a condition like seborrheic dermatitis rather than an AIDS-related skin manifestation. Choice D describes a presentation more typical of tinea corporis, which is not commonly seen in the axilla region in patients with AIDS.

Correct Answer: C

Rationale: The correct answer is C: Pull the pinna up and back before inserting the speculum. This is because pulling the pinna up and back straightens the auditory canal, allowing for easier and more accurate insertion of the speculum without causing discomfort or injury. Option A is incorrect as tilting the head forward may obstruct the view. Option B is incorrect as maintaining traction is essential for stability. Option D is incorrect as using the smallest speculum may not provide a clear view or proper insertion depth.
