Correct Answer: D

Rationale: The correct answer is D. Avoiding processed foods and canned soups is crucial for a client with hypertension on a low-sodium diet because these foods are typically high in sodium content. Fresh fruits and vegetables are generally healthy choices but may still contain some natural sodium. While limiting sodium intake to 2 grams per day is important, specifically avoiding processed foods and canned soups is more critical in this situation. Drinking water is essential for overall health but is not the most important instruction when focusing on reducing sodium intake.

Correct Answer: B

Rationale: In clients with hyperthyroidism experiencing palpitations, administering a beta-blocker is the appropriate intervention. Beta-blockers help reduce heart rate and control symptoms in hyperthyroidism. Encouraging rest (Choice A) may be helpful but does not directly address the palpitations. Drinking cool fluids (Choice C) and providing a cool environment (Choice D) are more focused on temperature regulation and comfort, which are not the primary interventions for palpitations in hyperthyroidism.

Correct Answer: D

Rationale: The correct first action for the nurse to take when a client receiving TPN is experiencing nausea and vomiting is to check the client's TPN bag for solution accuracy. This is crucial to ensure that the correct solution is being administered and to address any potential errors. Checking the blood glucose level or administering an antiemetic may be necessary interventions but addressing the TPN bag's accuracy should be the priority to prevent any complications related to incorrect TPN solution.

Correct Answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.

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.
