LPN Pharmacology Questions
Question 1 of 5
The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?
Correct Answer: A
Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications.
Question 2 of 5
While preparing a client for a cardiac catheterization, the client expresses a preference to speak with their doctor rather than the nurse. Which response by the nurse should be therapeutic?
Correct Answer: C
Rationale: The therapeutic response by the nurse in this situation involves reflecting the client's feelings back to them, which demonstrates active listening and empathy. By restating the client's preference to talk to their doctor, the nurse acknowledges and validates the client's feelings, thereby fostering a positive therapeutic relationship and promoting open communication.
Question 3 of 5
The client at risk for thrombophlebitis receives reinforcement from the LPN/LVN regarding measures to minimize its occurrence. Which statement by the client indicates an understanding of this information?
Correct Answer: B
Rationale: The correct answer is B. Taking frequent walks and avoiding prolonged bed rest are essential measures to promote circulation and reduce the risk of thrombophlebitis. Physical activity helps prevent blood from pooling and clotting in the veins, thus decreasing the likelihood of thrombophlebitis development.
Question 4 of 5
Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?
Correct Answer: A
Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.
Question 5 of 5
An ambulatory clinic nurse is interviewing a client who is complaining of flu-like symptoms. The client suddenly develops chest pain. Which question best assists the nurse in discriminating pain caused by a non-cardiac problem?
