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 caring for a client with a diagnosis of major depressive disorder who has been prescribed a selective serotonin reuptake inhibitor (SSRI). What is the most important teaching point?
- A. Take the medication with food.
- B. Expect to see improvement within 24 hours.
- C. Avoid drinking grapefruit juice.
- D. Report any thoughts of self-harm immediately.
Correct Answer: D
Rationale: The correct answer is D: 'Report any thoughts of self-harm immediately.' Clients prescribed SSRIs should be educated to report any thoughts of self-harm promptly, as these medications can initially increase suicidal ideation. Choice A is incorrect because SSRIs are usually taken on an empty stomach. Choice B is incorrect as it takes several weeks for SSRIs to reach their full effectiveness. Choice C is irrelevant to SSRI therapy.
The nurse is caring for a client with an intravenous infusion of normal saline. The client reports pain and swelling at the IV site. What is the nurse's priority action?
- A. Slow the rate of infusion
- B. Apply a warm compress to the site
- C. Discontinue the IV infusion
- D. Elevate the affected arm
Correct Answer: C
Rationale: The correct answer is to discontinue the IV infusion (Choice C). Pain and swelling at the IV site can indicate infiltration or phlebitis, which are serious complications that require immediate action. Slowing the rate of infusion (Choice A) may not address the underlying issue and can potentially worsen the condition. Applying a warm compress (Choice B) may provide temporary relief but does not address the need to discontinue the infusion. Elevating the affected arm (Choice D) is not the priority in this situation; discontinuing the infusion takes precedence to prevent further harm.
The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?
- A. The solution's rate is too rapid
- B. The client has phlebitis
- C. The infusion site is infected
- D. The infusion is infiltrated
Correct Answer: D
Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.
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.
What is the most important information for the nurse to provide to a client with a diagnosis of major depressive disorder who is started on a selective serotonin reuptake inhibitor (SSRI)?
- A. Take the medication with food
- B. Avoid foods high in tyramine
- C. Report any thoughts of self-harm immediately
- D. Expect to see improvement within 24 hours
Correct Answer: C
Rationale: The correct answer is C: 'Report any thoughts of self-harm immediately.' When starting an SSRI, clients should be informed to report any thoughts of self-harm promptly. SSRIs can initially increase suicidal ideation, especially in the early stages of treatment. This information is crucial for the client's safety and well-being. Choices A, B, and D are incorrect because taking the medication with food, avoiding foods high in tyramine, and expecting immediate improvement within 24 hours are not the most critical pieces of information for a client starting on an SSRI.
