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.

Correct Answer: B

Rationale: The correct answer is B: pearly grey and slightly concave. This is because a healthy tympanic membrane should appear pearly grey in color and slightly concave in shape. The pearly grey color indicates normal transparency and reflection of light, while the slightly concave shape is indicative of a normal eardrum. Choice A is incorrect as a light pink color and slight bulge are not characteristic of a healthy tympanic membrane. Choice C is incorrect because a pulled-in appearance at the base of the cone of light suggests retraction, which is abnormal. Choice D is incorrect as a whitish color with a small fleck of light is not a typical presentation of a healthy tympanic membrane.

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.

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: D

Rationale: The signs and symptoms - severe headache, high fever, and neck stiffness - in a young adult point towards meningeal inflammation. The combination of these symptoms is indicative of a potential infection or inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. The presence of fever and neck stiffness, in addition to the severe headache, raises concern for meningitis, an infection of the meninges. This is a medical emergency that requires prompt evaluation and treatment. Other choices are incorrect because: A: Head injury usually presents with a history of trauma, which is not mentioned in the scenario. B: Cluster headaches typically do not present with fever and neck stiffness. C: Migraine headaches do not typically cause such high fever and neck stiffness.
