Pharmacology for LPN

Correct Answer: A

Rationale: The correct preoperative instruction that the LPN/LVN should reinforce to a client scheduled for a carotid endarterectomy is being NPO after midnight before the surgery. This instruction is essential to prevent aspiration and ensure a safe procedure. Avoiding oral intake helps reduce the risk of complications during anesthesia induction and the surgical process. Choices B, C, and D are incorrect because avoiding deep breathing and coughing, resuming normal eating and drinking, and taking all prescribed medications the morning of surgery are not recommended preoperative instructions for a carotid endarterectomy.

Correct Answer: C

Rationale: The correct instruction for the nurse to reinforce to the client regarding furosemide (Lasix) is to report any muscle cramps or weakness to the healthcare provider. Muscle cramps or weakness may indicate hypokalemia, a potential side effect of furosemide. Monitoring and reporting these symptoms promptly can help in preventing complications related to electrolyte imbalances. Choice A is incorrect because furosemide should be taken on an empty stomach. Choice B is not directly related to furosemide use; in fact, foods high in potassium may be beneficial for clients taking furosemide to prevent hypokalemia. Choice D is a common expected side effect of furosemide due to its diuretic action but is not as crucial to report as potential signs of electrolyte imbalances.

Correct Answer: D

Rationale: A productive cough can indicate pulmonary toxicity, a serious side effect of amiodarone, and should be reported. Dry skin is not typically associated with amiodarone use. Weight loss is a common side effect of amiodarone but not generally a cause for concern unless severe. Bradycardia is a known side effect of amiodarone and may not necessarily require immediate reporting unless symptomatic.

Correct Answer: D

Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.

Correct Answer: A

Rationale: When administering potassium chloride to a client with hypokalemia, the nurse should monitor for hyperkalemia. Potassium chloride supplementation aims to increase potassium levels in individuals with hypokalemia. However, excessive administration can lead to hyperkalemia, which can be a serious and potentially life-threatening complication. Monitoring potassium levels is crucial to prevent this adverse outcome. Hypokalemia (Choice B) is the condition being treated, so it is not a complication of treatment. Hypernatremia (Choice C) refers to high sodium levels and is not directly related to the administration of potassium chloride. Hypercalcemia (Choice D) is an elevated calcium level and is not a common complication associated with potassium chloride administration in hypokalemia.
