LPN Pharmacology Practice Test
1. A client has a new prescription for prednisone. Which of the following statements should the nurse include in teaching the client?
- A. You may experience weight gain.
- B. Increase your intake of vitamin K.
- C. Expect increased urinary output.
- D. You may have dark, tarry stools.
Correct answer: A
Rationale: The correct answer is A. Weight gain is a common side effect of prednisone. The nurse should educate the client about the possibility of weight gain and the need to monitor it closely during treatment with prednisone. Choice B is incorrect because increasing vitamin K intake is not specifically related to prednisone therapy. Choice C is incorrect as prednisone is more likely to cause fluid retention rather than increased urinary output. Choice D is incorrect as dark, tarry stools are not a common side effect of prednisone.
2. A client has a new prescription for nitroglycerin. Which of the following instructions should the nurse include?
- A. Store the medication in a cool, dry place.
- B. Take the medication as directed by the healthcare provider.
- C. Take the medication 30 minutes before meals.
- D. Take the medication at the first sign of chest pain.
Correct answer: D
Rationale: Instructing the client to take nitroglycerin at the first sign of chest pain is crucial for immediate relief of angina symptoms. Nitroglycerin is a fast-acting medication that helps dilate blood vessels, improving blood flow to the heart muscle. Therefore, prompt administration at the onset of chest pain is essential to alleviate anginal episodes effectively. Choices A, B, and C are incorrect because storing the medication properly, taking it as directed, or before meals are not specific instructions for managing acute anginal episodes, which require immediate action for symptom relief.
3. The healthcare provider assesses a client who has been prescribed furosemide (Lasix) for cardiac disease. Which electrocardiographic change would be a concern for a client taking a diuretic?
- A. Tall, spiked T waves
- B. A prolonged QT interval
- C. A widening QRS complex
- D. Presence of a U wave
Correct answer: D
Rationale: The presence of a U wave is often associated with hypokalemia, a possible side effect of diuretic therapy like furosemide. Hypokalemia can lead to U wave formation on an electrocardiogram, making the presence of U waves a concerning finding in clients taking diuretics. Tall, spiked T waves are typically seen in hyperkalemia, not hypokalemia. A prolonged QT interval is more commonly associated with conditions like Long QT syndrome or certain medications, not specifically with diuretics. A widening QRS complex is usually seen in conditions affecting the conduction system of the heart, such as bundle branch blocks, rather than being directly related to diuretic use.
4. The LPN/LVN is reinforcing instructions to a client on the use of a metered-dose inhaler. The nurse should recognize that the client is using the inhaler correctly if the client takes which action?
- A. Takes a deep breath and then exhales just before administration
- B. Holds the mouthpiece 1 to 2 inches from the mouth
- C. Inhales the medication and then exhales immediately after administration
- D. Performs 3 short inhalations and then exhales deeply after administration
Correct answer: A
Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects. Choice B is incorrect because holding the mouthpiece 1 to 2 inches from the mouth is not a crucial step for using a metered-dose inhaler correctly. Choice C is incorrect because inhaling the medication and then exhaling immediately after administration would not allow the medication to be adequately absorbed into the lungs. Choice D is incorrect because performing 3 short inhalations and then exhaling deeply after administration is not the correct technique for using a metered-dose inhaler.
5. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?
- A. Aspirin
- B. Nitroglycerin
- C. Atenolol
- D. Simvastatin
Correct answer: B
Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.
