LPN Pharmacology Questions

Question 1 of 5

A client is admitted to the hospital with a venous stasis leg ulcer. The nurse inspects the ulcer expecting to note which observation?

Correct Answer: D

Rationale: When assessing a venous stasis leg ulcer, the nurse should expect to note a brownish or 'brawny' appearance. This discoloration is often due to hemosiderin deposits. This characteristic finding helps differentiate venous stasis ulcers from other types of ulcers, making it crucial for accurate diagnosis and appropriate treatment.

Question 2 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 3 of 5

A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?

Correct Answer: B

Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest.

Question 4 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 5 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.
