The nurse is preparing to administer a blood transfusion to a client. Which action is most important for the nurse to take before starting the transfusion?

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: C

Rationale: The correct answer is C: Pasta with marinara sauce. Clients with renal disease following a low-protein diet should opt for lower-protein options. Pasta with marinara sauce is a suitable choice as it is lower in protein compared to grilled chicken, tofu, or salmon. Grilled chicken, tofu, and salmon are higher in protein content and are not ideal for individuals following a low-protein diet for renal disease as they may strain the kidneys.

Correct Answer: B

Rationale: Clients with peripheral artery disease often experience claudication (leg pain during walking) due to decreased blood flow. Encouraging rest breaks during walking helps to manage pain and improve circulation. Rest breaks allow the muscles to recover from ischemia caused by inadequate blood supply. Increasing physical activity without breaks may worsen the symptoms. Applying warm compresses can potentially lead to burns or skin damage in individuals with compromised circulation. Massaging the affected leg is contraindicated in peripheral artery disease as it can further compromise blood flow.

Correct Answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

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.

Correct Answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

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: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

Correct Answer: A

Rationale: All of these tasks fall within the PN's scope of practice, which includes performing surgical dressing changes, taking postoperative vital signs, and administering insulin under supervision. The RN can delegate these tasks to the PN safely. Choice A is the correct answer because all the tasks mentioned are appropriate for delegation to a PN. Choice B should not be assigned to a PN as only RNs should administer insulin. Choice C is suitable for delegation to a PN as obtaining vital signs falls within their scope of practice. Choice D is also appropriate for delegation to a PN as performing surgical dressing changes is within their scope of practice.
