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: In sepsis with multi-organ failure, monitoring intake and output is critical to assess renal function and fluid balance, as organ failure can cause fluid shifts and decreased kidney function. Antibiotics are essential to treat the infection, but monitoring intake and output provides real-time insight into the client's status, helping to detect early signs of worsening organ function. Early ambulation and blood glucose monitoring are important aspects of care but are not as crucial as maintaining strict intake and output in this situation.

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: D

Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.

Correct Answer: B

Rationale: For a client with severe neutropenia, it is crucial to recommend a snack that is low in bacteria to reduce the risk of infection. Yogurt with fresh berries is an excellent choice as it is not only low in bacteria but also provides nutritional value. Baked apples with raisins (choice A) may not be ideal as the preparation process could introduce bacteria. Avocados and cheese (choice C) may not be the best option due to their potential bacterial content. Fresh fruit salad (choice D) may have a higher risk of bacterial contamination compared to yogurt with fresh berries.
