Correct Answer: B

Rationale: The bright cherry-red coloring in a semiconscious woman found on the floor in her kitchen indicates carbon monoxide poisoning. Carbon monoxide binds to hemoglobin with a higher affinity than oxygen, leading to tissue hypoxia and the characteristic cherry-red coloration. Polycythemia would result in a purplish-red color, carotenemia in a yellow-orange hue, and uremia in a pale or yellowish complexion. Therefore, the correct answer is B, as it aligns with the clinical presentation and pathophysiology of carbon monoxide poisoning.

Correct Answer: C

Rationale: Step 1: Dark skin may not show cyanosis well, making choice A less reliable. Step 2: Erythema refers to redness, which may not be easily visible in dark skin, making choice B less suitable. Step 3: Palpating for edema and increased warmth allows for a more reliable assessment of inflammation in dark skin, making choice C the correct answer. Step 4: Palpating for tenderness and ecchymosis may be useful but not specific to inflammation assessment in dark skin, making choice D less relevant.

Correct Answer: C

Rationale: Step-by-step rationale for why choice C (CN VII) is correct: 1. Palpebral fissures are controlled by muscles innervated by CN VII (facial nerve). 2. Damage to CN VII can result in facial asymmetry, affecting palpebral fissures. 3. CN III (choice A) controls eye movement, not palpebral fissures. 4. CN V (choice B) controls facial sensation, not palpebral fissures. 5. CN VIII (choice D) controls hearing and balance, not palpebral fissures. Summary: Choice C is correct as damage to CN VII affects palpebral fissures due to facial muscle innervation. Choices A, B, and D are incorrect as they do not control the muscles responsible for palpebral fissures.

Correct Answer: D

Rationale: The correct answer is D: lichenification. Lichenification is the thickening and hardening of the skin due to chronic scratching or rubbing. In this case, the patient's continuous scratching has led to lichenification. The term "terrible itch" indicates a persistent and severe itching sensation, which aligns with the chronic scratching behavior. Choices A, B, and C are not correct because a keloid is an overgrowth of scar tissue, a fissure is a small cut or crack in the skin, and keratosis is the thickening of the outer layer of the skin. These conditions are not directly related to chronic scratching behavior.

Correct Answer: C

Rationale: The correct answer is C: "This is a fungal infection caused by all the antibiotics you've received." The black, hairy tongue is a known side effect of prolonged antibiotic use, which disrupts the balance of normal oral flora and predisposes to fungal overgrowth, specifically of the yeast Candida. Antibiotics can eliminate the competing bacteria that normally keep Candida in check. Therefore, the patient's symptoms are most likely due to a fungal infection related to antibiotic therapy, rather than a bacterial issue or temporary overgrowth of hair. Biopsy is not necessary as the condition is commonly seen in this context and can be managed with appropriate treatment for fungal overgrowth.
