A charge nurse is teaching a newly licensed nurse about fluid shifts. The newly licensed nurse asks why sodium levels are high during dehydration. Which of the following responses should the charge nurse provide?

Water moves from areas where the concentration of sodium is higher to areas where the concentration is lower.

Water moves from areas where the concentration of sodium is lower to areas where the concentration is higher.

Sodium moves from areas where the concentration of solute is lower to areas where the concentration is higher.

Water and sodium particles move together to areas where sodium particles are higher.

Answer and Explanation

The Correct Answer is B

Choice A reason: This statement is incorrect because, during dehydration, water does not move towards areas of lower sodium concentration.

Choice B reason: This is correct because, during dehydration, the body retains sodium, and water follows by osmosis to areas where sodium concentration is higher, which can result in elevated sodium levels.

Choice C reason: Sodium does not typically move across membranes in response to solute concentration gradients; water does.

Choice D reason: Water moves independently of sodium particles, not necessarily together, and it moves towards areas of higher solute concentration.

Correct Answer is A

Explanation

Choice A reason: General anesthesia can impair the autonomic nervous system, which controls bladder function, leading to urinary retention. This risk is particularly high shortly after surgery.

Choice B reason: While liver failure can lead to multiple organ dysfunction, it is not directly associated with urinary retention unless there are concurrent issues affecting the urinary system.

Choice C reason: A diet high in calcium oxalate can contribute to kidney stones, which could potentially cause urinary obstruction, but it is not a direct cause of urinary retention.

Choice D reason: Antibiotics for a skin infection would not typically lead to urinary retention unless there were an allergic reaction or other rare side effects that affect the urinary system.

A. Increased urinary output B. Bradycardia C. Nausea and vomiting D. Hyperactive bowel sounds

Correct Answer is C

Explanation

Choice A reason: Increased urinary output is not typically associated with peritonitis, especially during peritoneal

dialysis.

Choice B reason: Bradycardia, or a slow heart rate, is not a common manifestation of peritonitis.

Choice C reason: Nausea and vomiting are common symptoms of peritonitis and should be monitored in clients

receiving peritoneal dialysis.

Choice D reason: Hyperactive bowel sounds are not specifically indicative of peritonitis; they can be associated with a variety of gastrointestinal conditions.
