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. The nurse is caring for a client who has just undergone a total hip replacement. Which intervention is most important to prevent postoperative complications?

• A. Encourage early ambulation
• B. Apply ice to the surgical site
• C. Monitor the surgical site for signs of infection
• D. Administer pain medication as prescribed

Correct answer: A

Rationale: Encouraging early ambulation is crucial following a total hip replacement surgery as it helps prevent complications such as deep vein thrombosis (DVT) by promoting circulation. Early ambulation also aids in preventing pneumonia, muscle atrophy, and pressure ulcers. Applying ice to the surgical site may help with pain and swelling, but it is not as critical in preventing complications as early ambulation. While monitoring the surgical site for signs of infection is important, it is not as crucial in preventing postoperative complications compared to early ambulation. Administering pain medication as prescribed is essential for comfort and pain management but does not directly prevent postoperative complications like early ambulation does.

3. 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.

4. 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.

5. The nurse is assessing a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT levels
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct answer: D

Rationale: In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This finding indicates impaired liver function affecting the synthesis of clotting factors, leading to an increased risk of bleeding. Elevated AST and ALT levels (Choice A) indicate liver cell damage but do not directly correlate with the risk of bleeding. A decreased albumin level (Choice B) is common in liver disease but is not the most concerning in terms of bleeding risk. Elevated bilirubin levels (Choice C) are seen in liver disease but do not directly reflect the risk of bleeding as PT/INR values do.
