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 is scheduled for an exercise electrocardiography (ECG) test. The nurse should explain that the purpose of this test is to evaluate which factor?

Correct Answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions.

Question 3 of 5

A client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. The nurse should reinforce with the client the importance of reporting which potential side effect?

Correct Answer: C

Rationale: Gingival bleeding is a common side effect of anticoagulant therapy. Anticoagulants work by prolonging the time it takes for blood to clot, which can lead to bleeding issues, including gingival bleeding. Since bleeding, including gingival bleeding, can be a serious side effect that requires medical attention, the client should be educated on reporting it promptly to their healthcare provider.

Question 4 of 5

A client is admitted to the hospital with a diagnosis of pericarditis. The nurse reviews the client's record for which sign or symptom that differentiates pericarditis from other cardiopulmonary problems?

Correct Answer: B

Rationale: Pericardial friction rub is a distinctive sign of pericarditis, characterized by a scraping or grating sound heard on auscultation, which helps differentiate pericarditis from other cardiopulmonary conditions. Anterior chest pain may be present in various cardiopulmonary issues. Weakness and irritability are nonspecific symptoms, and chest pain worsening with inspiration is more indicative of pleuritic conditions.

Question 5 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.
