LPN Pharmacology Practice Questions

1. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.

2. A client with a history of congestive heart failure (CHF) is receiving digoxin (Lanoxin). The nurse should monitor the client for which sign of digoxin toxicity?

Correct answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. The nurse should closely monitor the client's heart rate for any signs of slowing down, as it can indicate toxicity and potentially lead to serious complications. Hypertension, hyperglycemia, and insomnia are not typically associated with digoxin toxicity. Hypertension is more commonly associated with other conditions or medications, hyperglycemia can be seen in conditions like diabetes or certain medications, and insomnia is not a typical sign of digoxin toxicity.

3. While assessing a client taking propranolol, which finding should the nurse report to the provider?

Correct answer: A

Rationale: Bradycardia is a significant side effect of propranolol, a beta-blocker that slows the heart rate. It indicates potential cardiovascular complications and should be reported promptly to the healthcare provider for further evaluation and management. Dry mouth, constipation, and increased appetite are common side effects of various medications but are not directly associated with propranolol's mechanism of action.

4. A client diagnosed with thrombophlebitis 1 day ago suddenly complains of chest pain and shortness of breath. The LPN/LVN understands that a life-threatening complication of this condition is which?

Correct answer: C

Rationale: The correct answer is C, Pulmonary embolism. Pulmonary embolism is a critical complication of thrombophlebitis where a blood clot dislodges and travels to the lungs, obstructing blood flow. This obstruction can lead to chest pain, shortness of breath, and potentially fatal consequences, making it a life-threatening emergency that requires prompt intervention. Choices A, B, and D are incorrect because pneumonia, pulmonary edema, and myocardial infarction are not directly associated with thrombophlebitis and would not present with the sudden onset of chest pain and shortness of breath in this context.

5. A client with a history of angina pectoris reports chest pain after climbing stairs. What should be the nurse's first action?

Correct answer: C

Rationale: The correct action for a client experiencing anginal pain, like chest pain after climbing stairs, is to sit the client down and have them rest. Resting reduces myocardial oxygen demand, which can help relieve anginal pain. Administering oxygen or nitroglycerin may be appropriate interventions after the client has been seated and rested. Checking the client's blood pressure is important but not the immediate priority when a client is experiencing anginal pain. Therefore, the first action should be to sit the client down and allow them to rest.
