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 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 3 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 4 of 5

A client has a history of left-sided heart failure. The nurse should look for the presence of which finding to determine whether the problem is currently active?

Correct Answer: B

Rationale: When assessing a client with a history of left-sided heart failure, the presence of bilateral lung crackles is a key finding to determine if the condition is currently active. Crackles in the lungs indicate fluid accumulation, a common sign of left-sided heart failure due to pulmonary congestion.

Question 5 of 5

The nurse is planning measures to decrease the incidence of chest pain for a client with angina pectoris. The nurse should do which intervention to effectively accomplish this goal?

Correct Answer: A

Rationale: A calm and quiet environment helps reduce stress and prevents the occurrence of chest pain in clients with angina.
