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: A dark retinal background. This is because individuals of African descent typically have a higher concentration of melanin in their eyes, resulting in a darker retinal background. This can affect the appearance of the fundus during eye examinations. Incorrect choices: A: Increased night vision - Night vision is not directly influenced by melanin levels in the eyes and is more related to the function of rods and cones in the retina. C: Increased photosensitivity - Melanin provides some protection against UV light, so individuals with darker retinas may have lower photosensitivity. D: Narrowed palpebral fissures - Palpebral fissures refer to the opening between the eyelids and are not typically influenced by melanin levels in the eyes.

Correct Answer: B

Rationale: The correct answer is B: acute otitis media. In this case, the presentation of a bright red tympanic membrane and absence of the light reflex are indicative of inflammation and fluid accumulation in the middle ear, which are classic signs of acute otitis media. This condition commonly occurs in young children, especially after a recent upper respiratory infection. Incorrect choices: A: Fungal infection is less likely in this case as the symptoms are more consistent with acute bacterial infection seen in otitis media. C: Rupture of the drum would typically present with sudden relief of pain and discharge from the ear, which is not described in the scenario. D: Blood behind the drum (hemotympanum) is uncommon in children with acute otitis media and would usually be associated with trauma or barotrauma.

Correct Answer: A

Rationale: The correct answer is A because one pinch of smokeless tobacco (SLT) in the mouth for 30 minutes can indeed deliver a similar amount of nicotine as smoking one cigarette. This is because the nicotine in SLT is absorbed through the oral mucosa directly into the bloodstream, providing a quick effect. This statement is accurate and reflects the pharmacokinetics of SLT use. Option B is incorrect because smoking carries a higher risk of oral cancer compared to SLT use. Option C is incorrect as pain is not always an early sign of oral cancer, and other symptoms such as non-healing sores or lumps may indicate oral cancer. Option D is incorrect as pain can sometimes be an early sign of oral cancer, especially in advanced stages.

Correct Answer: A

Rationale: The correct answer is A: she may have macular degeneration. Macular degeneration is characterized by loss of central vision while peripheral vision remains intact. In this case, the woman's difficulty with tasks that require central vision, such as reading and recognizing faces, points towards macular degeneration. The other choices are incorrect because: B: Her symptoms indicate a specific vision problem, not just age-related changes. C: Cataracts typically cause blurred vision, not loss of central vision. D: Glaucoma typically affects peripheral vision first before progressing to central vision loss.
