LPN Pharmacology Assessment A Questions

Question 1 of 5

A client with chronic heart failure is being discharged with a prescription for digoxin (Lanoxin). Which instruction should the nurse reinforce?

Correct Answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm.

Question 2 of 5

A client with a diagnosis of angina pectoris is prescribed nitroglycerin tablets. How should the nurse instruct the client to take the medication?

Correct Answer: B

Rationale: Nitroglycerin is most effective when administered sublingually (under the tongue) as it is rapidly absorbed into the bloodstream. Placing the tablet under the tongue allows for quick absorption and faster relief of angina symptoms. Chewing the tablet, swallowing it, or placing it between the cheek and gum would not provide the same rapid onset of action needed during an angina episode.

Question 3 of 5

The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

Correct Answer: C

Rationale: When a client is receiving furosemide, which is a loop diuretic, it can lead to potassium loss. Therefore, monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias.

Question 4 of 5

The LPN/LVN is assisting in the care of a client with a diagnosis of heart failure who is receiving digoxin (Lanoxin). Which laboratory result should the nurse monitor closely?

Correct Answer: B

Rationale: The correct answer is serum potassium. Monitoring serum potassium levels is crucial when a client is receiving digoxin (Lanoxin) because low potassium levels can increase the risk of digoxin toxicity. Digoxin and low potassium levels can lead to serious cardiac complications, such as arrhythmias. Therefore, close monitoring of serum potassium is essential to prevent adverse effects and ensure the safe administration of digoxin in clients with heart failure.

Question 5 of 5

A client has a new prescription for rifampin. Which of the following instructions should the nurse include?

Correct Answer: B

Rationale: The correct answer is to inform the client to expect red-orange discoloration of body fluids when taking rifampin. This side effect is harmless but can be surprising to patients. It is important for the nurse to educate the client about this expected change to prevent unnecessary concern or alarm. Monitoring for hyperglycemia is not directly related to rifampin, and taking the medication with food or avoiding dairy products are not specific instructions for this medication.
