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 requires application of an eye shield to the right eye. What should the nurse do in order to apply tape to anchor the shield most effectively?

• A. Place tape from the cheek to the forehead
• B. Secure tape from the nose to the ear
• C. Attach tape from the lower eyelid to the upper forehead
• D. Use circular bandaging around the head

Correct answer: C

Rationale: The correct way to apply tape to anchor an eye shield effectively is to attach the tape from the lower eyelid to the upper forehead. This method provides stability for the shield without putting pressure on the eye itself, thus helping to protect the eye. Choices A, B, and D are incorrect because taping from the cheek to the forehead, securing tape from the nose to the ear, or using circular bandaging around the head may not provide the necessary stability and protection required for the eye shield.

3. A client is admitted with a diagnosis of pneumonia. Which intervention should the nurse implement to promote airway clearance?

• A. Administer bronchodilators as prescribed.
• B. Encourage increased fluid intake.
• C. Perform chest physiotherapy.
• D. Provide humidified oxygen.

Correct answer: B

Rationale: Encouraging increased fluid intake is the most appropriate intervention to promote airway clearance in a client with pneumonia. Adequate hydration helps to thin respiratory secretions, making it easier for the client to cough up and clear the airways. Administering bronchodilators (Choice A) may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy (Choice C) can be beneficial in certain cases but may not be the initial intervention for promoting airway clearance. Providing humidified oxygen (Choice D) can help improve oxygenation but does not specifically target airway clearance in pneumonia.

4. The client has chronic renal failure. What dietary modification is most important for this client?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase sodium intake
• D. Encourage dairy products

Correct answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.

5. During a routine prenatal visit, a nurse measures a client’s fundal height. The client is 26 weeks pregnant. What should the fundal height be?

• A. Approximately 26 cm
• B. Between 24 to 28 cm
• C. Above the umbilicus by two finger widths
• D. Below the xiphoid process

Correct answer: B

Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.
