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 client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

3. The nurse is planning care for a 12-year-old child with sickle cell disease in a vaso-occlusive crisis affecting the elbow. Which one of the following should be the priority?

• A. Limiting fluids
• B. Client-controlled analgesia
• C. Applying cold compresses to the elbow
• D. Performing passive range of motion exercises

Correct answer: B

Rationale: During a vaso-occlusive crisis in sickle cell disease, the priority intervention is effective pain management. Client-controlled analgesia allows the child to self-administer pain relief as needed, promoting comfort and reducing stress. Limiting fluids (choice A) is not appropriate in this scenario as hydration is essential to prevent complications. Cold compresses (choice C) may provide some comfort but do not address the underlying pain. Passive range of motion exercises (choice D) are contraindicated during a vaso-occlusive crisis due to the risk of further pain and tissue damage.

4. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?

• A. Change the catheter dressing every 72 hours.
• B. Flush the catheter with heparin solution daily.
• C. Ensure the catheter is clamped when not in use.
• D. Maintain sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.

5. A parent asks a nurse about his infant's expected physical development during the first year of life. Which of the following information should the nurse include?

• A. A 10-month-old infant can pull up to a standing position.
• B. A 6-month-old infant can walk with assistance.
• C. A 12-month-old infant can jump with both feet.
• D. An 8-month-old infant can crawl on hands and knees.

Correct answer: A

Rationale: The correct answer is A. By 10 months, infants can typically pull up to a standing position as part of their physical development. Walking with assistance usually begins around 9-12 months, not at 6 months (choice B). Jumping with both feet is a skill that usually develops around 24 months, not at 12 months (choice C). Crawling on hands and knees typically starts around 6-9 months, not at 8 months (choice D). Therefore, the most accurate information to include for an infant's expected physical development at 10 months is the ability to pull up to a standing position.
