Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client receiving total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. This practice helps reduce the risk of infection in clients receiving parenteral nutrition. Measuring the client's blood glucose level every 6 hours is important for clients on insulin therapy or with diabetes, but it is not directly related to TPN administration. Weighing the client weekly is essential for monitoring fluid status and nutritional progress, but it is not specific to TPN care. Administering TPN through a peripheral IV line is incorrect because TPN solutions are hypertonic and can cause phlebitis or thrombosis if administered through a peripheral line; a central venous access is typically used for TPN administration.

Correct Answer: B

Rationale: The correct answer is to 'Use a 7th-grade reading level.' This ensures that the material is accessible to most clients by keeping the language simple and easy to understand. Emphasizing important information using bold lettering (Choice A) can be helpful but may not enhance overall readability. Avoiding cartoons (Choice C) is not a universal rule and can sometimes make the material more engaging. Using words with three or four syllables (Choice D) can make the material difficult to comprehend for many clients.

Correct Answer: A

Rationale: In this scenario, postoperative chest pain is a critical finding that must be reported promptly. Chest pain after an arterial thrombectomy could indicate serious complications such as myocardial infarction or pulmonary embolism. Muscle spasms and cool, moist skin are not the priority assessments in this situation. Incisional pain is common after surgery and is not typically a cause for immediate concern unless it is severe and accompanied by other symptoms.

Correct Answer: C

Rationale: The correct action the nurse should take when administering potassium chloride IV to a client with hypokalemia is to infuse the medication at a rate of 10 mEq/hr. This slow infusion rate is crucial to prevent the development of hyperkalemia, a potentially dangerous condition. Option A is incorrect because giving the medication as a bolus over 10 minutes can lead to adverse effects. Option B is incorrect as potassium chloride does not necessarily need to be diluted before administration in this scenario. Option D is incorrect as administering the medication undiluted can also increase the risk of hyperkalemia.

Correct Answer: D

Rationale: Corrected Rationale: Blurred vision is a classic sign of digoxin toxicity, indicating a potential overdose. It is crucial to recognize this symptom promptly and report it to the healthcare provider for immediate intervention. Bradycardia and nausea are common side effects of digoxin but not specific indicators of toxicity. Tachycardia is unlikely in digoxin toxicity since it usually causes a decrease in heart rate.
