Correct Answer: C

Rationale: The correct action for the nurse to take when caring for a client with a chest tube connected to a water-seal drainage system is to add sterile water to the water-seal chamber. This is necessary to maintain the correct water level for proper chest tube function. Clamping the chest tube during ambulation (Choice A) is incorrect as it can lead to complications by obstructing drainage. Keeping the collection chamber below the level of the chest (Choice B) is incorrect because it should be kept below the chest to facilitate drainage. Emptying the collection chamber every 12 hours (Choice D) is incorrect as it should be emptied whenever it reaches the fill line or as per facility policy, not on a fixed time schedule.

Correct Answer: D

Rationale: The correct answer is D, dark-colored urine. Dark-colored urine can indicate various issues such as dehydration, liver problems, or blood in the urine, which could be concerning and require further evaluation by the provider. Choices A, B, and C are not necessarily findings that would need immediate reporting to the provider. A urine output of 50 mL in 2 hours might be low but could be influenced by various factors and might not always require immediate action. The presence of an indwelling urinary catheter is a known history and not a new finding. Frequent urination at night could be a symptom related to various conditions but may not be an urgent concern unless accompanied by other significant symptoms.

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.

Correct Answer: C

Rationale: The correct answer is C: 'Use a Z-track technique to administer the injection.' When administering IM injections, using a Z-track technique helps prevent medication from leaking into subcutaneous tissues. This technique involves pulling the skin laterally, injecting the medication deeply into the muscle, and then releasing the skin. Choice A is incorrect because massaging the injection site after administering the medication can lead to increased blood flow and potential leakage of the medication. Choice B is incorrect as the needle should typically be inserted at a 90° angle for IM injections to ensure proper delivery into the muscle. Choice D is incorrect as aspirating for blood before injecting the medication is not routinely recommended for IM injections.

Correct Answer: C

Rationale: The correct action for the nurse to take is to limit IV exposure to light. Nitroprusside is light-sensitive, and exposure to light can lead to its degradation, potentially reducing its efficacy in treating severe hypertension. Keeping calcium gluconate at the bedside (Choice A) is not directly related to managing nitroprusside infusion. While monitoring blood pressure every 2 hours (Choice B) is important in managing hypertension, it is not the immediate action required to ensure medication efficacy. Attaching an inline filter to the IV tubing (Choice D) may help filter particles but does not address the critical concern of light sensitivity associated with nitroprusside administration.
