A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?

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: 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: B

Rationale: The most important instruction for the nurse to provide to a client following a cystectomy and urinary diversion is to report any signs of cloudy urine output. Cloudy urine may indicate infection, which is a serious concern in clients with a urinary diversion. Instructing the client to report any signs of infection immediately is crucial to prevent complications. Avoiding heavy lifting is important for postoperative recovery but not as critical as identifying a potential infection. Drinking an adequate amount of water is generally beneficial for health but not the most crucial instruction in this scenario. While monitoring for signs of infection at the surgical site is essential, cloudy urine is a more specific and immediate indicator of a potential problem in clients with urinary diversions.

Correct Answer: B

Rationale: The correct answer is B: Assess for signs of hypocalcemia. After a thyroidectomy, monitoring for hypocalcemia is crucial because damage to the parathyroid glands during surgery can result in low calcium levels, which may cause life-threatening complications. Monitoring respiratory rate and rhythm (choice A) is important but not the most critical in this situation. Monitoring for elevated body temperature (choice C) is less of a priority post-thyroidectomy. Checking blood pressure every 30 minutes (choice D) is not as vital as monitoring for hypocalcemia in this context.

Correct Answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.
