Correct Answer: B

Rationale: The correct answer is B. Altered consciousness within the first 24 hours after a temporal injury is a classic sign of epidural hematoma, which is a neurosurgical emergency. This finding occurs due to the rapid expansion of the hematoma, causing compression of the brain. Nausea and vomiting (choice A) are more commonly associated with other types of head injuries, such as concussion. Severe headache and blurred vision (choice C) are symptoms seen in various head injuries but are not specific to epidural hematomas. Loss of motor function on the affected side (choice D) is more indicative of a different type of head injury, such as a contusion or intracerebral hematoma.

Correct Answer: D

Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.

Correct Answer: C

Rationale: The correct answer is to advise the client to apply ice to the breasts for comfort. Applying ice can help reduce swelling and discomfort associated with engorgement in a woman who is not breastfeeding. Expressing milk manually would stimulate further milk production, which is not desired in this case. Wearing a tight bra could increase discomfort by putting pressure on the engorged breasts. Warm showers may actually increase swelling due to the vasodilation effect of heat.

Correct Answer: C

Rationale: The correct answer is to avoid alcohol consumption while taking metformin. Alcohol can increase the risk of lactic acidosis when combined with metformin. Choice A is incorrect because metformin is usually recommended to be taken with meals to reduce GI upset. Choice B is important but not the priority; muscle pain is more commonly associated with other diabetes medications. Choice D is incorrect because metformin typically does not cause hypoglycemia but rather helps control blood sugar levels in type 2 diabetes.

Correct Answer: A

Rationale: Corrected Rationale: In clients with cirrhosis, elevated ammonia levels can lead to hepatic encephalopathy, which is a serious complication. Monitoring ammonia levels is crucial to assess for changes in mental status and initiate treatment if needed. White blood cell count (choice B) is not the most important parameter to monitor in this scenario as it does not directly relate to the complications of cirrhosis. Albumin level (choice C) and hemoglobin level (choice D) are also important in cirrhosis, but in this case, monitoring ammonia level takes precedence due to its direct association with hepatic encephalopathy.
