Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client receiving nitroprusside for severe hypertension is to limit light exposure to the IV infusion. Nitroprusside is light-sensitive, and exposure to light can lead to degradation of the medication, reducing its effectiveness. Administering oxygen (Choice A) may be necessary for some clients but is not directly related to the administration of nitroprusside. Monitoring blood pressure every 2 hours (Choice B) is a general nursing intervention for clients with hypertension but does not specifically address the administration of nitroprusside. Attaching an inline filter to the IV tubing (Choice D) is not necessary to address the specific concern of light exposure related to nitroprusside administration.

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.

Correct Answer: A

Rationale: The correct action for the nurse to take is to flush the tube with 30 mL of sterile water before each feeding. This helps maintain tube patency and prevents clogs. Choice B is incorrect because enteral feedings should be administered using a gravity drip method or a pump, not through a large-bore syringe. Choice C is incorrect because the head of the bed should be elevated to at least 30 degrees to reduce the risk of aspiration. Choice D is incorrect because the feeding bag should be replaced every 24 hours to prevent bacterial contamination.

Correct Answer: C

Rationale: The correct action to reduce the risk of aspiration in clients receiving enteral feedings is to elevate the head of the bed during feedings. This position helps prevent regurgitation and aspiration of the feeding. Positioning the client supine (Choice A) increases the risk of aspiration as it promotes reflux. Administering feedings over 10 minutes (Choice B) does not directly reduce the risk of aspiration. Placing the client in a lateral position after feedings (Choice D) does not address the risk of aspiration during the feeding process.

Correct Answer: C

Rationale: Continuous bubbling in the water seal chamber should be reported to the provider as it can indicate an air leak. This finding suggests that air is escaping from the pleural space, which can lead to lung collapse or pneumothorax. Drainage of 75 mL in the past 24 hours is within the expected range for a client with a chest tube and is not a cause for concern. Intermittent bubbling in the water seal chamber is a normal finding that indicates the system is functioning properly. Tidaling in the water seal chamber is also an expected finding that shows the fluctuation of fluid with the client's breathing and is not alarming.
