LPN Pharmacology Questions
Question 1 of 5
The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?
Correct Answer: B
Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG.
Question 2 of 5
A client receives discharge teaching for a new prescription of lithium. Which instruction should be included?
Correct Answer: B
Rationale: Increasing sodium intake is essential when taking lithium to counteract the risk of developing hyponatremia. Lithium can lead to decreased sodium levels, so increasing sodium intake can help maintain an adequate balance and prevent complications.
Question 3 of 5
A client with known coronary artery disease (CAD) begins to experience chest pain while getting out of bed. What action should the nurse take?
Correct Answer: B
Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain.
Question 4 of 5
The LPN/LVN is reinforcing instructions to a client on the use of a metered-dose inhaler. The nurse should recognize that the client is using the inhaler correctly if the client takes which action?
Correct Answer: A
Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects.
Question 5 of 5
The client is being ambulated due to activity intolerance caused by bacterial endocarditis. How can the nurse determine that the client is best tolerating ambulation?
Correct Answer: D
Rationale: A slight increase in blood pressure without significant symptoms indicates that the client is tolerating the activity. In this scenario, a mild increase in blood pressure without other symptoms is a positive sign of tolerance to ambulation despite the underlying condition of bacterial endocarditis.
