Correct Answer: A

Rationale: The correct answer is A: Acyclovir. The rationale is that sudden sensorineural hearing loss (SSHL) can sometimes be associated with viral infections, such as herpes simplex virus. Acyclovir is an antiviral medication that can potentially help treat the underlying viral infection causing SSHL. It is important to address the potential viral etiology before considering other treatments. Summary of other choices: B: Furosemide is a diuretic used to treat conditions like high blood pressure and edema, not SSHL. C: Warfarin is an anticoagulant used to prevent blood clots, not indicated for SSHL. D: Hyperbaric oxygen therapy is sometimes used for SSHL, but addressing any potential viral infection with Acyclovir would be a more appropriate initial step.

Correct Answer: C

Rationale: The correct answer is C: Couvelaire uterus. This condition refers to the bruised and edematous appearance of the uterus associated with placental abruption. Placental abruption occurs when the placenta separates from the uterine wall prematurely, leading to bleeding and a compromised blood supply to the uterus. The bruised appearance is due to blood infiltrating the myometrium. Explanation for other choices: A: Wernicke’s encephalopathy - This is a neurological disorder caused by thiamine deficiency, not related to uterine issues. B: Uterine prolapse - This is the descent or herniation of the uterus into or beyond the vaginal canal, not related to placental abruption. D: Asherman’s syndrome - This is characterized by intrauterine adhesions or scar tissue, typically a result of uterine surgery, not associated with placental abruption.

Correct Answer: B

Rationale: The correct answer is B: Hyperextension casting. The AGACNP knows that this treatment is appropriate for a condition that requires immobilization and support while allowing controlled movement. Hyperextension casting provides stability and support while promoting healing. Observation (A) would not provide adequate treatment for a condition requiring immobilization. Jewett brace (C) is typically used for spinal fractures, not for conditions that require hyperextension casting. Surgical intervention (D) would be considered if conservative measures like casting have failed.

Correct Answer: B

Rationale: Step 1: Post-splenectomy, platelet count typically drops temporarily, leading to a risk of bleeding. Step 2: To compensate, the body increases hemoglobin (Hgb) levels to maintain oxygen-carrying capacity. Step 3: Therefore, on postoperative day 2, an increased Hgb level is expected. Summary: A is incorrect because MCV is not typically affected in this scenario. C is incorrect because platelet count usually decreases post-splenectomy. D is incorrect as albumin levels are not directly impacted by splenectomy for ITP.

Correct Answer: A

Rationale: The correct answer is A because secondary postpartum hemorrhage typically occurs between the 8th-14th day postpartum and can extend up to 6 weeks after delivery. This timeframe aligns with the physiological changes and healing process after childbirth. Choice B is incorrect because it contradicts the established timeframe for secondary postpartum hemorrhage. Choice C is incorrect as secondary postpartum hemorrhage is not rare but rather a recognized complication that can occur after childbirth. Choice D is incorrect as secondary postpartum hemorrhage does not happen sporadically, but rather follows a defined timeframe based on postpartum physiological changes.
