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. 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.

3. A client is admitted to the hospital with a diagnosis of Pneumonia. Which intervention should the nurse implement to prevent complications associated with Pneumonia?

• A. Encourage mobilization and ambulation
• B. Encourage energy conservation with complete bed rest
• C. Provide humidified oxygen via nasal cannula
• D. Restrict oral (PO) and intravenous fluids

Correct answer: A

Rationale: The correct intervention to prevent complications associated with pneumonia is to encourage mobilization and ambulation. These activities help prevent complications such as atelectasis by promoting lung expansion. Encouraging energy conservation with complete bed rest (Choice B) is not ideal as it can lead to complications like muscle weakness and decreased lung expansion. Providing humidified oxygen via nasal cannula (Choice C) is important in pneumonia treatment but does not directly prevent complications associated with pneumonia itself. Restricting oral (PO) and intravenous fluids (Choice D) is not recommended as adequate hydration is crucial for pneumonia patients to maintain respiratory function and overall health.

4. The client with hypertension is being taught about lifestyle changes. Which recommendation is most important to include?

• A. Increase sodium intake
• B. Engage in regular physical activity
• C. Consume a diet high in saturated fats
• D. Limit fluid intake

Correct answer: B

Rationale: Engaging in regular physical activity is crucial for managing hypertension as it helps lower blood pressure. Regular exercise can improve heart health, increase circulation, and contribute to overall well-being, all of which are beneficial for individuals with hypertension. Choice A, increasing sodium intake, is incorrect as reducing sodium is recommended for hypertension to help lower blood pressure. Choice C, consuming a diet high in saturated fats, is incorrect as a diet high in saturated fats can negatively impact blood pressure and cardiovascular health. Choice D, limiting fluid intake, is incorrect as maintaining adequate hydration is important for overall health and not directly related to hypertension management.

5. 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.
