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. Following an open reduction of the tibia, the nurse notes fresh bleeding on the client's cast. What intervention should the nurse implement?

• A. Assess the client's hemoglobin levels to determine if the client is in shock
• B. Call the surgeon and prepare to take the client back to the operating room
• C. Outline the area with ink and check it every 15 minutes to monitor for changes in bleeding
• D. No action is required as postoperative bleeding can be expected

Correct answer: C

Rationale: In this scenario, the correct intervention is to outline the area with ink and check it every 15 minutes to monitor for changes in bleeding. This approach helps in assessing the extent and progression of the bleeding. Option A is incorrect because assessing hemoglobin levels would not provide immediate information on the ongoing bleeding. Option B is premature without first monitoring the bleeding site. Option D is incorrect because although some postoperative bleeding can be expected, fresh bleeding on the cast warrants immediate monitoring and evaluation.

3. When caring for a client with a urinary catheter, what is the most important intervention to prevent infection?

• A. Use sterile technique for catheter care
• B. Ensure the catheter bag is below the level of the bladder
• C. Provide perineal care daily
• D. Change the catheter only when necessary

Correct answer: B

Rationale: The most important intervention to prevent infection when caring for a client with a urinary catheter is to ensure that the catheter bag is below the level of the bladder. This positioning helps prevent urine backflow, reducing the risk of infection. While using sterile technique for catheter care (Choice A) is important, ensuring proper drainage by keeping the catheter bag below the bladder is crucial to prevent infection. Providing perineal care daily (Choice C) is essential for hygiene but not directly related to preventing catheter-related infections. Changing the catheter only when necessary (Choice D) is important for maintenance, but correct positioning of the catheter bag is more critical in preventing immediate infection.

4. The client with hypertension is being taught about lifestyle modifications. What topic is most important?

• A. Stress management
• B. Salt intake reduction
• C. Regular physical activity
• D. Weight loss

Correct answer: B

Rationale: Reducing salt intake is crucial for managing hypertension. Excessive salt consumption can lead to fluid retention, increasing blood pressure. While stress management, regular physical activity, and weight loss are beneficial for overall health, reducing salt intake is the most important lifestyle modification for controlling hypertension. Stress management may help reduce overall stress levels but does not directly impact blood pressure as salt intake does. Regular physical activity and weight loss can also benefit blood pressure control, but the immediate impact of reducing salt intake is more significant.

5. When inserting an indwelling urinary catheter in a female client and urine flows into the tubing, what is the next action?

• A. Document the color and clarity of the urine
• B. Insert the catheter an additional inch
• C. Ask the client to breathe deeply and slowly exhale
• D. Inflate the balloon with 5 mL of sterile water

Correct answer: D

Rationale: When urine flows into the tubing during the insertion of an indwelling urinary catheter, it confirms proper catheter placement. The next step should be to inflate the balloon with the specified amount of sterile water to secure the catheter in place. Documenting the color and clarity of the urine (choice A) is important for assessment but not the immediate next action. Inserting the catheter further (choice B) without securing it could cause harm. Asking the client to breathe deeply (choice C) is not relevant to this situation.
