1. The provider orders Lanoxin (digoxin) 0.125 mg PO and furosemide 40 mg every day. Which of these foods would the nurse reinforce for the client to eat at least daily?
- A. Spaghetti
- B. Watermelon
- C. Chicken
- D. Tomatoes
Correct answer: B
Rationale: The correct answer is B: Watermelon. Watermelon is high in potassium, which is important to eat daily when taking furosemide to prevent hypokalemia. Furosemide is a diuretic that can lead to potassium loss, so consuming potassium-rich foods like watermelon helps maintain adequate potassium levels. Spaghetti, chicken, and tomatoes are not as high in potassium and therefore not as beneficial in preventing hypokalemia related to furosemide use.
2. A client with heart failure is being taught by a nurse on reducing daily sodium intake. Which factor is most crucial in determining the client’s ability to learn new dietary habits?
- A. The client's involvement in planning the change
- B. The cost of the dietary changes
- C. The availability of low-sodium foods
- D. The client’s previous dietary knowledge
Correct answer: D
Rationale: The client’s previous dietary knowledge is the most critical factor in determining the ability to learn new dietary habits. Understanding the client's existing dietary knowledge helps tailor the teaching to build upon what they already know. While client involvement in planning changes can increase adherence and motivation, the foundational knowledge is essential for effective learning. The cost of dietary changes and the availability of low-sodium foods are important considerations but not as crucial as the client's existing knowledge.
3. The nurse is caring for a client diagnosed with hypothyroidism. Which finding should the nurse expect to observe?
- A. Weight gain
- B. Heat intolerance
- C. Increased appetite
- D. Frequent diarrhea
Correct answer: A
Rationale: The correct answer is weight gain. In hypothyroidism, there is a decrease in metabolic rate, which can lead to weight gain. Heat intolerance (choice B) is more commonly associated with hyperthyroidism. Increased appetite (choice C) and frequent diarrhea (choice D) are not typical findings in hypothyroidism. Therefore, choices B, C, and D are incorrect.
4. What intervention should be implemented by the LPN to reduce the risk of aspiration in a client with a nasogastric tube receiving continuous enteral feedings?
- A. Elevate the head of the bed to 30-45 degrees.
- B. Check residual volumes every 4 hours.
- C. Verify tube placement every shift.
- D. Flush the tube with water every 4 hours.
Correct answer: A
Rationale: Elevating the head of the bed to 30-45 degrees is crucial in reducing the risk of aspiration because it helps keep the gastric contents lower than the esophagus, thereby promoting proper digestion and preventing reflux. This position also aids in reducing the likelihood of regurgitation and aspiration of gastric contents. Checking residual volumes every 4 hours is important for monitoring feeding tolerance but does not directly address the risk of aspiration. Verifying tube placement every shift is essential for ensuring the tube is correctly positioned within the gastrointestinal tract but does not directly reduce the risk of aspiration. Flushing the tube with water every 4 hours may help maintain tube patency and prevent clogging, but it does not specifically address the risk of aspiration associated with nasogastric tube feedings.
5. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Increased serum hemoglobin levels
- D. Decreased serum potassium levels
Correct answer: B
Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.
