Nursing Elites

1. What is the most important action for preventing infection in a client with a central venous catheter?

• A. Changing the catheter dressing every 72 hours.
• B. Flushing the catheter with heparin solution daily.
• C. Ensuring the catheter is clamped when not in use.
• D. Maintaining sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.

2. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?

• A. Serum albumin 3 g/dL
• B. Total lymphocyte count 2400/mm3
• C. HCT 42%
• D. HGB 16 g/dL

Correct answer: A

Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.

3. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 0.5 mL
• B. 1 mL
• C. 1.5 mL
• D. 2 mL

Correct answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

4. A 3-year-old child has had multiple tooth extractions while under general anesthesia. The client returns from the post-anesthesia care unit crying but awake. Which approach is likely to be successful?

• A. Examine the mouth first
• B. Reassure the child
• C. Examine the mouth last
• D. Offer a pacifier

Correct answer: C

Rationale: In this scenario, it is crucial to prioritize the comfort of the child. By examining the mouth last, discomfort is minimized, and the child is given the opportunity to settle down. Choosing to examine the mouth first may escalate the distress of the child further. While reassuring the child is important, in this case, addressing the physical discomfort before providing emotional reassurance is more effective. Offering a pacifier may provide some comfort, but addressing the immediate physical discomfort by examining the mouth last is the most appropriate action to help the child settle down after the procedure.

5. A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?

• A. Daily weight
• B. Intake and output
• C. Urine specific gravity
• D. Peripheral edema

Correct answer: A

Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
