Correct Answer: C

Rationale: The correct answer is C: turbinates. Turbinates are bony projections in the nasal cavity that increase the surface area for the warming, humidifying, and filtering of inhaled air. Meatus (A) refers to the passages in the nasal cavity, not the projections. Septum (B) is the partition between the nostrils, not the projections. Kiesselbach's plexus (D) is a collection of blood vessels in the nasal septum, not the projections that increase surface area.

Correct Answer: B

Rationale: The correct answer is B: Lyme disease. The presentation of a red circular rash with central clearing, known as erythema migrans, following a hiking trip in the summer is highly indicative of Lyme disease. The specific distribution of the rash across the midriff and behind the knees aligns with typical areas where the rash appears in Lyme disease cases. This rash is a hallmark sign of early Lyme disease caused by the bacterium Borrelia burgdorferi transmitted through the bite of an infected tick. Other answer choices are incorrect because rubeola presents with a different rash pattern, an allergy to mosquito bites would not typically present in this manner, and Rocky Mountain spotted fever typically presents with a different rash appearance and distribution.

Correct Answer: B

Rationale: The correct answer is B because people of African descent commonly have a pigmented layer near the outer canthus of the lower lid called the "plica semilunaris." This is a normal anatomical variation in this population. Yellow fatty deposits over the cornea (choice A) are not typical findings in this demographic. Yellow color of the sclera extending up to the iris (choice C) is not a characteristic feature. The presence of small brown macules on the sclera (choice D) is also not a common finding in individuals of African descent.

Correct Answer: A

Rationale: The correct answer is A: acquired immunodeficiency syndrome (AIDS). The dark red confluent macule on the hard palate is known as Kaposi's sarcoma, a common manifestation of AIDS. This lesion is caused by Human Herpesvirus 8 and is often seen in patients with compromised immune systems. Measles (B) typically presents with a rash, not a dark red macule. Leukemia (C) does not typically manifest as a dark red macule in the mouth. Carcinoma (D) refers to cancer and would present differently than Kaposi's sarcoma. In summary, the presence of a dark red confluent macule on the hard palate in a patient with a history of intravenous drug abuse is highly suggestive of AIDS, specifically Kaposi's sarcoma.
