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 with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. What is the next appropriate nursing action?
Correct Answer: A
Rationale: If chest pain persists after the first dose of nitroglycerin, it is appropriate to administer a second dose while continuing to monitor the client's response. Nitroglycerin is a vasodilator commonly used to relieve angina symptoms by dilating blood vessels and increasing blood flow to the heart. Reassessing the client's response and providing a second dose may be necessary to achieve adequate pain relief and improve blood flow to the heart.
Question 3 of 5
Before administering digoxin (Lanoxin) to a client diagnosed with heart failure, the nurse should perform which assessment?
Correct Answer: C
Rationale: Assessing the apical pulse is crucial before administering digoxin because the medication can lead to bradycardia. Monitoring the apical pulse helps determine the heart rate, and digoxin is typically withheld if the pulse is below 60 beats per minute. This assessment is essential to prevent potential adverse effects associated with digoxin administration.
Question 4 of 5
The client will wear a Holter monitor for continuous cardiac monitoring over the next 24 hours. What action should the nurse take to assist the client?
Correct Answer: B
Rationale: Providing the client with a device holder to wear around the waist allows them to comfortably carry the Holter monitor while engaging in normal activities throughout the 24-hour monitoring period. This approach supports the client's mobility and ensures the monitor is securely in place for accurate readings.
Question 5 of 5
After returning the client to bed following a cardiac catheterization procedure with the left femoral vessel as the access site, the nurse places a sign above the bed instructing the client to remain on bed rest and in which position?
Correct Answer: C
Rationale: After cardiac catheterization via the femoral vessel, it is crucial to keep the head of the bed elevated no more than 15 degrees to prevent bleeding at the access site. This position helps maintain pressure on the femoral artery, reducing the risk of bleeding and complications post-procedure.
