Nursing Elites

1. When teaching a group of school-aged children how to reduce the risk for Lyme disease, which instruction should the camp nurse include?

• A. Wash hands frequently.
• B. Avoid drinking lake water.
• C. Do not share personal products.
• D. Wear long sleeves and pants.

Correct answer: D

Rationale: The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.

2. Which nonfood item is the most common cause of respiratory arrest in young children?

• A. Broken rattles
• B. Buttons
• C. Pacifiers
• D. Latex balloons

Correct answer: D

Rationale: The correct answer is D, Latex balloons. Latex balloons can pose a significant choking hazard to young children if inhaled, potentially leading to respiratory arrest. Broken rattles, buttons, and pacifiers are not typically known to cause respiratory arrest in young children. While these items can present choking hazards as well, the most common cause of respiratory arrest among young children is due to inhaling latex balloons.

3. After placement of a left subclavian central venous catheter (CVC), the nurse receives a report of the X-ray findings indicating that the CVC tip is in the client's superior vena cava. Which action should the nurse implement?

• A. Remove the catheter and apply direct pressure for 5 minutes.
• B. Initiate intravenous fluids as prescribed.
• C. Secure the catheter using aseptic technique.
• D. Notify the healthcare provider of the need to reposition the catheter.

Correct answer: B

Rationale: Initiating intravenous fluids as prescribed is the appropriate action when the CVC tip is correctly placed in the superior vena cava. Intravenous fluids can now be administered effectively through the central line. Removing the catheter and applying direct pressure is unnecessary and not indicated as the tip is in the correct position. Securing the catheter using aseptic technique is important for preventing infections but is not the immediate action needed in this situation. Notifying the healthcare provider of the need to reposition the catheter may delay necessary fluid administration, which is the priority at this time.

4. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

5. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
