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: 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: C

Rationale: The correct answer is C: the presence of shadows, which may indicate glaucoma. When a light is directed across the iris from the temporal side, it helps in evaluating the presence of shadows in the anterior chamber angle, which can suggest a narrow or closed angle glaucoma. This technique is known as transillumination test and is important in detecting potential glaucoma cases. A: Drainage from dacryocystitis is incorrect as it is typically assessed by pressing on the lacrimal sac area to observe for discharge. B: Conjunctivitis over the iris is incorrect as conjunctivitis is an inflammation of the conjunctiva, not the iris. D: A scattered light reflex indicative of cataracts is incorrect as cataracts cause clouding of the lens, not scattering of light across the iris.

Correct Answer: C

Rationale: The correct answer is C because the trigeminal (CN V) and the trochlear (CN IV) nerves are indeed stimulated when the outer surface of the eye is stimulated. The trigeminal nerve is responsible for the sensation of touch in the face and controls the muscles involved in chewing. The trochlear nerve controls the superior oblique muscle of the eye, which helps with downward and inward eye movements. Therefore, when the outer layer of the eye is touched or stimulated, these nerves are activated to convey the sensation to the brain. Choices A, B, and D are incorrect: A: The outer layer of the eye is not particularly sensitive to touch compared to other areas like the cornea or conjunctiva. B: The outer layer of the eye is not darkly pigmented; the pigmented layer is actually the uvea inside the eye. D: The visual receptive layer of the eye, known as the retina, is located deeper within the eye, not

Correct Answer: D

Rationale: The correct answer is D because over-the-counter nasal sprays, especially those containing decongestants, can lead to rebound swelling when used for an extended period. Rebound swelling occurs when the nasal passages become more congested after the effects of the medication wear off. This can result in a cycle of dependency on the nasal spray to alleviate symptoms, leading to worsening congestion over time. It is important for the nurse to educate the patient about this potential risk and suggest alternative treatment options to address her allergies effectively without causing rebound swelling. Choices A, B, and C are incorrect because: A: Incorrect, as not all over-the-counter nasal sprays carry a risk of addiction. B: Incorrect, as switching to another brand may not address the underlying issue of rebound swelling. C: Incorrect, as continuous use of the nasal spray without addressing rebound swelling can exacerbate the problem.
