Nursing Elites

1. 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.

2. During a bed bath, the nurse observes that a client's IV site is red and swollen. What should the nurse do first?

• A. Discontinue the IV under physician's guidance
• B. Apply a warm compress to the site
• C. Notify the physician
• D. Document the appearance of the site and continue the bath

Correct answer: C

Rationale: The correct first action when a nurse observes a red and swollen IV site during a bed bath is to notify the physician. This is crucial because prompt reporting allows for immediate intervention to prevent further complications. Discontinuing the IV (Choice A) should only be done under the physician's guidance to avoid any adverse effects and ensure proper care. Applying a warm compress (Choice B) may not address the underlying issue and could potentially worsen the situation if the cause is an infection or infiltration. Documenting the site's appearance and continuing the bath (Choice D) without immediate action might delay necessary treatment, leading to potential complications.

3. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?

• A. Ensure the IV is flowing freely
• B. Mix the medication thoroughly
• C. Check the client’s electrolyte levels
• D. Obtain a baseline ECG

Correct answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

4. The healthcare provider is providing discharge instructions to a client with chronic heart failure. Which dietary recommendation is most appropriate?

• A. Increase fluid intake.
• B. Follow a low-sodium diet.
• C. Follow a high-protein diet.
• D. Increase sodium intake.

Correct answer: B

Rationale: The most appropriate dietary recommendation for a client with chronic heart failure is to follow a low-sodium diet. This helps manage the condition by reducing fluid retention and the workload on the heart. High fluid intake can lead to fluid overload and exacerbate heart failure symptoms. While protein is important for overall health, a high-protein diet is not specifically indicated for chronic heart failure. Increasing sodium intake is contraindicated in heart failure as it can worsen fluid retention and increase the workload on the heart.

5. A client with heart failure is prescribed a low-sodium diet. The nurse notices the client's meal tray contains high-sodium foods. What action should the nurse take?

• A. Educate the client about the importance of a low-sodium diet
• B. Replace the meal with a low-sodium option
• C. Report the error to the dietary department
• D. Encourage the client to avoid eating the high-sodium foods

Correct answer: B

Rationale: The correct action for the nurse to take in this situation is to replace the high-sodium meal with a low-sodium option. This immediate intervention ensures that the client adheres to the prescribed low-sodium diet, crucial for managing heart failure and preventing fluid retention. Educating the client (Choice A) about the diet is important but not as urgent as ensuring they receive the correct meal. Reporting the error to the dietary department (Choice C) can be done after addressing the immediate issue. Encouraging the client to avoid high-sodium foods (Choice D) is not as effective as replacing the current meal with a suitable alternative.
