1. The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse’s priority action?
- A. Hold the spironolactone and notify the healthcare provider.
- B. Administer potassium supplements.
- C. Continue the spironolactone as ordered.
- D. Increase the dose of spironolactone.
Correct answer: A
Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.
2. What is a severe and often sudden allergic reaction that can lead to breathing difficulties and anaphylactic shock?
- A. Anaphylaxis
- B. Allergic rhinitis
- C. Bronchospasm
- D. Asthma attack
Correct answer: A
Rationale: Anaphylaxis is the correct answer. It is a severe allergic reaction that can result in difficulty breathing, a drop in blood pressure, and even anaphylactic shock if not treated promptly. Choice B, allergic rhinitis, is characterized by symptoms such as a runny or stuffy nose, sneezing, and itching. Choice C, bronchospasm, refers to the sudden constriction of the muscles in the walls of the bronchioles, leading to breathing difficulties. Choice D, asthma attack, involves the inflammation and narrowing of the airways, resulting in symptoms like wheezing, coughing, and chest tightness.
3. What test measures the electrical activity of the heart over a 24- or 48-hour period?
- A. Holter monitor
- B. Electrocardiogram
- C. Stress test
- D. Chest X-ray
Correct answer: A
Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that continuously records the heart's electrical activity over 24 to 48 hours, aiding in the diagnosis of arrhythmias and other heart conditions. Choice B, an Electrocardiogram, provides a snapshot of the heart's electrical activity at a specific point in time, not over an extended period like a Holter monitor. Choice C, a Stress test, measures how the heart responds to physical activity and is not used for continuous monitoring of electrical activity. Choice D, a Chest X-ray, is used to visualize the structures of the chest, not to measure the heart's electrical activity.
4. For what reason might the nurse be given an order to administer milrinone (Primacor)?
- A. For congestive heart failure
- B. For hypertension
- C. For cardiac arrhythmias
- D. For bradycardia
Correct answer: A
Rationale: Milrinone is commonly prescribed for congestive heart failure to help improve cardiac function and alleviate symptoms. Choices B, C, and D are incorrect as milrinone is not typically used for hypertension, cardiac arrhythmias, or bradycardia. It is specifically indicated for congestive heart failure for short-term management.
5. The client is prescribed warfarin. What should the client be taught about this medication?
- A. Avoid foods high in vitamin K.
- B. Take the medication with food to prevent stomach upset.
- C. Take the medication at the same time every day.
- D. Increase the dose if a dose is missed.
Correct answer: A
Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is an anticoagulant medication, and vitamin K can counteract its effects. Therefore, it is important for clients taking warfarin to avoid foods high in vitamin K to maintain the medication's effectiveness. Choice B is incorrect because warfarin should be taken consistently as prescribed, regardless of food intake. Choice C is incorrect because while consistency in timing is important, it is not specific to the effectiveness of warfarin. Choice D is incorrect because clients should never increase the dose of warfarin on their own, especially to make up for a missed dose, as it can lead to serious bleeding risks.
