LPN Pharmacology Practice Questions
1. The healthcare provider is monitoring a client following cardioversion. Which observation should be of the highest priority to the healthcare provider?
- A. Blood pressure
- B. Status of airway
- C. Oxygen flow rate
- D. Level of consciousness
Correct answer: B
Rationale: The status of the airway is the highest priority following cardioversion as it ensures proper oxygenation and helps prevent complications such as airway obstruction and respiratory distress. Maintaining a patent airway is crucial for the client's respiratory function and overall well-being immediately after cardioversion. Monitoring the airway ensures that the client can breathe effectively and minimizes the risk of hypoxia and other serious respiratory issues. While blood pressure, oxygen flow rate, and level of consciousness are also important parameters to monitor, they are secondary to ensuring a clear and patent airway for adequate oxygenation.
2. A client with a diagnosis of deep vein thrombosis (DVT) has been placed on bed rest. The LPN/LVN should reinforce which instruction to the client to prevent complications?
- A. Perform ankle pumps and circles every 1 to 2 hours.
- B. Use a heating pad to relieve pain in the affected leg.
- C. Keep the affected leg flat and avoid elevation.
- D. Wear tight compression stockings to prevent swelling.
Correct answer: A
Rationale: Performing ankle pumps and circles every 1 to 2 hours is crucial for a client with DVT on bed rest. These exercises promote venous return, preventing stasis and reducing the risk of complications such as pulmonary embolism. Ankle pumps help activate the calf muscle pump, assisting in propelling blood back to the heart and preventing blood clots from forming or worsening. Choice B is incorrect because using a heating pad can increase blood flow to the area, potentially dislodging a clot. Choice C is incorrect because elevation helps reduce swelling and improve venous return. Choice D is incorrect because although compression stockings can be beneficial, they are not the most important instruction for preventing complications in this scenario.
3. When providing teaching to a client with a new prescription for atorvastatin, which of the following instructions should the nurse include?
- A. Take the medication in the evening.
- B. Take the medication with food.
- C. Increase your intake of grapefruit juice.
- D. Avoid consuming dairy products.
Correct answer: A
Rationale: The correct instruction for a client with a new prescription for atorvastatin is to take the medication in the evening. Atorvastatin is more effective when taken at night because cholesterol synthesis is higher during this time. This timing helps optimize the drug's cholesterol-lowering effects and enhances its overall efficacy in managing lipid levels. Choices B, C, and D are incorrect. Taking atorvastatin with food can decrease its absorption, grapefruit juice can interact with atorvastatin leading to increased side effects, and there is no specific need to avoid dairy products while on atorvastatin unless instructed otherwise by the healthcare provider.
4. A client has a new prescription for amlodipine. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor blood pressure daily.
- C. Increase intake of potassium-rich foods.
- D. Avoid consuming grapefruit juice.
Correct answer: B
Rationale: The correct answer is B: 'Monitor blood pressure daily.' When a client is prescribed amlodipine, it is essential to monitor their blood pressure regularly. Amlodipine is known to cause hypotension, so monitoring blood pressure helps ensure it stays within the desired range to prevent complications associated with low blood pressure. Choice A is incorrect because amlodipine can be taken with or without food. Choice C is incorrect as increasing potassium intake is not a specific instruction related to amlodipine. Choice D is incorrect as grapefruit juice interactions are not typically a concern with amlodipine.
5. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?
- A. Tall, peaked T waves
- B. ST segment depressions
- C. Shortened P-R intervals
- D. Shortening of the QRS complex
Correct answer: A
Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.
