LPN Pharmacology Practice Questions

Correct Answer: B

Rationale: The correct next priority action after administering nitroglycerin to a client with CAD experiencing chest pain is to monitor the client's blood pressure. Nitroglycerin can cause hypotension, so it is crucial to assess and monitor the client's blood pressure for any signs of decreased perfusion or adverse effects. Obtaining a 12-lead ECG may be important but is not the immediate priority. Notifying the healthcare provider and administering a second dose of nitroglycerin should only be considered after ensuring the client's blood pressure is stable.

Correct Answer: B

Rationale: Furosemide is a loop diuretic that can lead to significant potassium loss, making it crucial to monitor the client's serum potassium levels. Hypokalemia (low potassium levels) can result from furosemide use, potentially leading to adverse effects such as cardiac dysrhythmias. Therefore, close monitoring of serum potassium levels is essential to prevent complications in clients receiving furosemide. Monitoring serum calcium, sodium, or glucose levels is not the priority when administering furosemide.

Correct Answer: D

Rationale: Elevated serum amylase and lipase levels are indicative of pancreatitis, a serious condition that can manifest with jaundice. Timely follow-up is crucial to manage pancreatitis and its complications effectively in a jaundiced client. Choices A, B, and C are less critical in this scenario. Urine specific gravity within normal range, frothy tea-colored urine, and clay-colored stools can be associated with various conditions but are not directly indicative of pancreatitis, which is the most concerning condition associated with jaundice.

Correct Answer: A

Rationale: The client's cracked tongue and sunken eyes indicate dehydration. Therefore, the priority nursing intervention is to help the client determine ways to increase his fluid intake. Dehydration can exacerbate the client's emphysema symptoms and lead to further complications. Monitoring and addressing the client's fluid intake is crucial for maintaining his health and well-being. Options B, C, and D are not the immediate priorities in this situation. While an eye examination, oxygen use, and sensitivity tests are relevant aspects of care, addressing dehydration through increased fluid intake takes precedence in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Hypokalemia. Furosemide, a loop diuretic, commonly causes potassium loss, leading to hypokalemia. The nurse should closely monitor for decreased potassium levels in a client receiving furosemide to prevent complications such as cardiac arrhythmias or muscle weakness. Hyperkalemia (Choice A) is not typically associated with furosemide use. Hypernatremia (Choice B) refers to high sodium levels and is not the primary concern with furosemide. Hyponatremia (Choice D) is low sodium levels, which can occur but is less common than hypokalemia in clients taking furosemide.
