Correct Answer: A

Rationale: The correct answer is A: Utilize a pressure-reducing mattress. This intervention is crucial for preventing pressure ulcers in patients at risk for impaired skin integrity, such as those with HIV. By redistributing pressure, a pressure-reducing mattress helps to alleviate pressure on vulnerable areas, reducing the risk of skin breakdown. Limiting physical activity (B) can lead to muscle atrophy and worsen skin integrity. Applying antibiotic ointment (C) may not address the root cause of skin breakdown. Avoiding synthetic fabrics (D) may be helpful in some cases, but it is not as effective as using a pressure-reducing mattress.

Correct Answer: D

Rationale: The correct answer is D: Leiomyoma. A leiomyoma is the medical term for a fibroid, which is a benign tumor of the uterus composed of smooth muscle tissue. This term is more appropriate as it specifically refers to fibroids. A: Bartholins cyst is a fluid-filled swelling in the Bartholin's gland, not related to fibroids. B: Dermoid cyst is a type of ovarian cyst containing tissues like hair, teeth, and skin, not related to fibroids. C: Hydatidiform mole is an abnormal growth of tissue in the uterus that forms during pregnancy, not related to fibroids.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Clear, watery fluid draining from the ear post-accident indicates a possible cerebrospinal fluid (CSF) leak, a serious condition requiring immediate medical attention to prevent complications such as meningitis. 2. CSF leak can result from a basilar skull fracture, common in head injuries like motorcycle accidents. 3. Prompt reporting of this finding by the nurse is crucial for timely intervention and prevention of potential life-threatening complications. Summary: A: Visualizing the malleus during otoscopic examination is normal and not an immediate concern in this scenario. B: A pearly gray tympanic membrane is a normal finding and does not indicate a serious issue post-accident. C: Tenderness in the mastoid area may suggest injury but is not as urgent as clear, watery fluid drainage indicative of a CSF leak.

Correct Answer: C

Rationale: The correct answer is C because it accurately explains the physiological change in the eye that leads to the need for bifocals. As individuals age, there is a gradual thickening of the lens of the eye, which affects the eye's ability to accommodate for near vision. This thickening makes it harder for the eye to focus on close objects, necessitating the use of bifocals to correct this near vision issue. Choices A, B, and D are incorrect because they do not provide a scientifically accurate explanation for the need for bifocals in older individuals. Option A is dismissive and does not address the specific change in the eye that leads to the need for bifocals. Option B implies aging as a general concept without specifying the relevant change in the eye. Option D incorrectly states that the eye gets shorter as we age, which is not the reason for needing bifocals.

Correct Answer: A

Rationale: The correct answer is A because floaters are commonly caused by age-related changes in the vitreous humor of the eye, such as the formation of tiny fibers or clumps. These floaters are typically harmless and not a cause for concern. Choice B is incorrect because glasses do not affect floaters in the eye. Choice C is incorrect because floaters are not a primary symptom of glaucoma. Choice D is incorrect because weakened ciliary muscles are not typically associated with floaters. Therefore, the most appropriate interpretation is that seeing floaters is a normal aging process of the eye.
