Correct Answer: A

Rationale: The correct answer is A: Serum albumin level. Serum albumin is an important indicator of nutritional status, as low levels may indicate malnutrition or inflammation commonly seen in AIDS patients. Weight history (B) is also relevant as weight changes can reflect nutritional status. White blood cell count (C) is not directly related to nutritional status. Body mass index (D) is a calculation based on weight and height, not a direct measure of nutritional status. Blood urea nitrogen (E) is a measure of kidney function, not a specific indicator of nutritional status. Therefore, the nurse should primarily focus on assessing the patient's serum albumin level for nutritional status evaluation in this case.

Correct Answer: B

Rationale: The correct answer is B: Total placenta previa. In this condition, the placenta completely covers the cervix, posing a risk of severe bleeding during vaginal delivery. Cesarean birth is necessary to avoid potential life-threatening complications for both the mother and the baby. Partial abruptio placentae (choice A) involves premature separation of the placenta, but it doesn't always require a cesarean birth. Ectopic pregnancy (choice C) occurs when the fertilized egg implants outside the uterus, typically requiring surgical intervention but not always a cesarean birth. Eclampsia (choice D) is a serious condition characterized by high blood pressure and seizures, but it doesn't always necessitate cesarean birth unless there are other complications that require it.

Correct Answer: A

Rationale: The correct answer is A: Application of topical antibiotic ointment. After enucleation, there is a risk of infection at the surgical site. By applying topical antibiotic ointment as directed, the patient can help prevent infection and promote healing. This is a crucial aspect of postoperative care. B: Maintenance of a supine position for the first 48 hours postoperative is incorrect. Patients may be advised to avoid lying flat on their back to prevent complications such as pressure on the surgical site. C: Fluid restriction to prevent orbital edema is incorrect. Fluid restriction is not typically necessary post-enucleation unless specifically advised by the healthcare provider. D: Administration of loop diuretics to prevent orbital edema is incorrect. Loop diuretics are not typically used for preventing orbital edema post-enucleation. E: Use of an ocular pressure dressing is incorrect. While dressings may be used postoperatively, the application of topical antibiotic ointment is more

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.

Correct Answer: D

Rationale: The correct answer is D: Labyrinthitis. This condition presents with sudden onset vertigo, nausea, vomiting, tinnitus, and hearing loss, which are all symptoms described by the patient. Labyrinthitis is commonly caused by a viral infection affecting the inner ear, leading to inflammation of the labyrinth. This inflammation disrupts the balance and hearing functions of the inner ear, resulting in the symptoms mentioned. A: Ossiculitis involves inflammation of the middle ear bones, typically causing conductive hearing loss, not the sudden onset of vertigo and other symptoms described. B: Mnire's disease is characterized by recurrent episodes of vertigo, tinnitus, and hearing loss, but it typically does not present with sudden onset incapacitating vertigo. C: Ototoxicity is caused by exposure to certain medications or chemicals that damage the inner ear structures, leading to hearing loss. While hearing loss is a symptom, the sudden onset of vertigo is not typically associated with ototoxicity.
