1. A client with atrial fibrillation is prescribed warfarin (Coumadin). The nurse should reinforce which dietary instruction?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of foods high in fiber.
- D. Increase protein intake.
Correct answer: A
Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.
2. A client with a diagnosis of heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). The LPN/LVN should closely monitor the client for which potential complication?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that promotes the loss of potassium in the urine, potentially leading to hypokalemia. Hypokalemia increases the risk of digoxin toxicity, as digoxin's effects can be potentiated in the presence of low potassium levels. Monitoring for hypokalemia is crucial to prevent adverse effects and maintain the therapeutic effectiveness of digoxin in clients with heart failure. Choices A, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hyponatremia. Instead, it commonly leads to hypokalemia due to increased potassium excretion.
3. A client has a new prescription for amitriptyline. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with a full glass of water.
- D. Monitor for signs of weight gain.
Correct answer: C
Rationale: When a client is prescribed amitriptyline, it is important to instruct them to take the medication with a full glass of water. This instruction helps prevent esophageal irritation, as amitriptyline can be harsh on the esophagus. Option C is the correct choice. Option A, taking the medication in the morning, is not specific to amitriptyline and can vary depending on the individual's condition. Option B, avoiding grapefruit juice, is a general precaution for many medications but not specifically related to amitriptyline. Option D, monitoring for signs of weight gain, is not a direct instruction for taking the medication itself and may not be a common side effect of amitriptyline.
4. A client is wearing a continuous cardiac monitor, which begins to alarm at the nurse's station. The nurse sees no electrocardiographic complexes on the screen. What should the nurse do first?
- A. Call a code blue.
- B. Call the healthcare provider.
- C. Check the client's status and lead placement.
- D. Press the recorder button on the ECG console.
Correct answer: C
Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.
5. The healthcare provider is reinforcing instructions to a client with heart failure who is prescribed a low-sodium diet. The provider should advise the client to choose which food item?
- A. Canned soup
- B. Fresh vegetables
- C. Processed cheese
- D. Pickled vegetables
Correct answer: B
Rationale: Fresh vegetables are a suitable choice for clients on a low-sodium diet as they are naturally low in sodium and provide essential nutrients. In contrast, canned soup, processed cheese, and pickled vegetables tend to be high in sodium, which is not recommended for individuals with heart failure and on a low-sodium diet. Fresh vegetables are also rich in fiber, vitamins, and minerals, making them a healthier option compared to the other choices provided.
