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.

The nurse is preparing a client for discharge after a major surgical procedure. What is the priority instruction to include in the discharge teaching?
- A. Signs of infection to monitor for
- B. Pain management techniques
- C. Activity restrictions and safety measures
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. Providing comprehensive discharge instructions covering signs of infection to monitor for, pain management techniques, activity restrictions, and safety measures is crucial after a major surgical procedure. Each of these components plays a vital role in the client's recovery and well-being. It is important for the client to understand how to identify signs of infection, manage pain effectively, and adhere to activity restrictions to prevent complications and ensure a smooth recovery process. While each instruction is important on its own, combining all aspects into the discharge teaching ensures that the client has a holistic understanding of their post-operative care, empowering them to take charge of their health and know when to seek further assistance if needed. Choices A, B, and C are essential components of discharge teaching and should all be included to provide the client with comprehensive care instructions.
The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
- A. Bed rest with bathroom privileges only
- B. Frequent, short walks with assistance
- C. Range of motion exercises to the knee every four hours
- D. Leg elevation to reduce swelling
Correct Answer: B
Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
The nurse is assessing an older resident with a history of Benign Prostatic Hypertrophy and identifies a distended bladder. What should the nurse do?
- A. Stand the client to void and run tap water within hearing distance before catheterizing
- B. Straight catheterize and if the residual urine volume is greater than 100 mL, clamp catheter
- C. Catheterize q2h and place in an indwelling catheter at the end of the prescribed 24hr period
- D. Catheterize with an indwelling catheter and if the residual volume is greater than 100 mL, inflate the balloon
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
A client with a urinary tract infection is prescribed antibiotics. What should the nurse inform the client about antibiotic therapy?
- A. It may interfere with oral contraceptive effectiveness
- B. It can cause drowsiness
- C. It should be taken with meals
- D. Completing the full course is crucial
Correct Answer: D
Rationale: Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. Informing the client about the importance of finishing the prescribed course helps in ensuring the effectiveness of the treatment and reduces the risk of recurrence. Choice A is incorrect because antibiotics do not generally interfere with oral contraceptive effectiveness. Choice B is incorrect because drowsiness is not a common side effect of antibiotics. Choice C is incorrect because while some antibiotics may need to be taken with meals, it is not a universal rule for all antibiotics.
The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?
- A. Restrict sodium intake
- B. Encourage high-protein meals
- C. Increase fluid intake
- D. Administer diuretics as prescribed
Correct Answer: D
Rationale: The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.
