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 with an indwelling urinary catheter. What is the most important action to prevent catheter-associated urinary tract infections (CAUTI)?

• A. Perform hand hygiene before and after handling the catheter
• B. Change the catheter every 72 hours
• C. Apply antibiotic ointment at the insertion site
• D. Irrigate the catheter daily

Correct answer: A

Rationale: Performing hand hygiene before and after handling the catheter is crucial in preventing catheter-associated urinary tract infections (CAUTI). This practice helps minimize the risk of introducing harmful microorganisms into the urinary tract. Changing the catheter every 72 hours is not recommended unless clinically indicated as it can increase the risk of infection. Applying antibiotic ointment at the insertion site is not a standard practice and may contribute to antibiotic resistance. Irrigating the catheter daily is unnecessary and can introduce pathogens into the urinary tract, increasing the risk of infection.

3. A client is admitted with a diagnosis of congestive heart failure (CHF). Which intervention is most important to include in the plan of care?

• A. Restrict fluid intake
• B. Provide a high-sodium diet
• C. Encourage vigorous exercise
• D. Administer bronchodilators as prescribed

Correct answer: A

Rationale: The correct answer is A: Restrict fluid intake. Fluid restriction is crucial in the management of congestive heart failure (CHF) as it helps prevent fluid overload, which can exacerbate CHF symptoms. Choices B, C, and D are incorrect. Providing a high-sodium diet would worsen fluid retention and increase the workload of the heart. Encouraging vigorous exercise can strain the heart further in CHF patients. Administering bronchodilators is not the priority intervention for CHF.

4. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.

5. The nurse is preparing a client for discharge following a myocardial infarction. What should the nurse prioritize in the discharge instructions?

• A. Warning signs of a potential heart attack
• B. Importance of medication adherence
• C. Follow-up appointment details
• D. All of the above

Correct answer: D

Rationale: When preparing a client for discharge after a myocardial infarction, the nurse should prioritize providing comprehensive instructions. This includes educating the client about warning signs of a potential heart attack to recognize symptoms early, stressing the importance of medication adherence for optimal recovery and prevention of further cardiac events, and ensuring understanding of follow-up appointment details for ongoing monitoring and care. All these aspects are crucial in preventing complications and promoting the client's well-being. Therefore, selecting 'All of the above' as the correct answer is the most appropriate choice. Choices A, B, and C are all essential components of a holistic discharge plan for a client post-myocardial infarction.
