1. While caring for a client receiving parenteral fluid therapy via a peripheral IV catheter, after which of the following observations should the nurse remove the IV catheter?
- A. Swelling and coolness are observed at the IV site.
- B. The client reports mild discomfort at the insertion site.
- C. The infusion rate is slower than expected.
- D. The IV catheter is no longer needed for treatment.
Correct answer: A
Rationale: Swelling and coolness at the IV site can indicate complications such as infiltration, which can lead to tissue damage or fluid leakage into the surrounding tissues. Prompt removal of the IV catheter is essential to prevent further complications. The client reporting mild discomfort at the insertion site is common during IV therapy and does not necessarily warrant catheter removal unless there are signs of infiltration. A slower than expected infusion rate may not always necessitate IV catheter removal; the nurse should troubleshoot potential causes such as kinks in the tubing or pump malfunctions first. Just because the IV catheter is no longer needed for treatment does not automatically mean it should be removed; proper assessment and monitoring for complications are still essential.
2. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Magnesium
Correct answer: A
Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.
3. To use proper body mechanics while making an occupied bed for a client on bed rest, the nurse should:
- A. Place the bed in a high horizontal position
- B. Use a low bed position
- C. Bend at the waist
- D. Keep the bed flat and at a comfortable working height
Correct answer: A
Rationale: When making an occupied bed for a client on bed rest, the nurse should place the bed in a high horizontal position to promote better body mechanics. This positioning helps reduce strain on the nurse's back and promotes proper alignment while working. Using a low bed position can lead to awkward bending and increased risk of musculoskeletal injuries. Bending at the waist is discouraged as it can strain the back. Keeping the bed flat and at a comfortable working height may not provide the optimal ergonomic setup needed to prevent injury.
4. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?
- A. Ventrogluteal site
- B. Dorsogluteal site
- C. Deltoid site
- D. Abdomen
Correct answer: D
Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.
5. Postoperative client with fluid volume deficit. Which change indicates successful treatment?
- A. Decrease in heart rate
- B. Increase in blood pressure
- C. Decrease in respiratory rate
- D. Increase in urine output
Correct answer: A
Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.
