Nursing Elites

1. A client with a history of chronic heart failure is admitted with symptoms of dyspnea and fatigue. What initial intervention should the nurse prepare to implement?

• A. Administration of IV diuretics
• B. Oxygen therapy
• C. Bed rest
• D. Dietary consultation

Correct answer: B

Rationale: The correct initial intervention for a client with chronic heart failure presenting with dyspnea and fatigue is oxygen therapy. Oxygen therapy can help relieve dyspnea and improve oxygen saturation levels, which are crucial in managing heart failure exacerbations. Administering IV diuretics may be necessary later to address fluid overload, but oxygen therapy takes precedence in addressing the immediate respiratory distress. Bed rest and dietary consultation are important aspects of care for heart failure patients, but in this scenario, oxygen therapy is the priority to improve the client's respiratory status.

2. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?

• A. 50
• B. 67
• C. 57
• D. 70

Correct answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL ÷ 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.

3. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

4. The client with a new colostomy is being taught about colostomy care. Which statement by the client indicates effective learning?

• A. I will change my colostomy bag every day.
• B. I should eat a low-fiber diet.
• C. I need to inspect the stoma daily for color and swelling.
• D. I can skip my colostomy care if I feel well.

Correct answer: C

Rationale: The correct answer is C because inspecting the stoma daily is crucial in identifying any early signs of complications or infections. Choice A is incorrect because changing the colostomy bag daily is not necessary unless there is a specific reason to do so. Choice B is incorrect as a low-fiber diet is not usually recommended for colostomy care. Choice D is incorrect because colostomy care should be performed regularly regardless of how the client feels.

5. 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.
