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.
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 C
Explanation
Choice A reason: The output solution is typically the same or slightly less than the input solution due to fluid removal during dialysis.
Choice B reason: The fluid from the abdomen should be clear or slightly yellow; any other color may indicate infection or bleeding.
Choice C reason: Using a microwave to warm the solution is not recommended as it can unevenly heat the solution and damage its composition.
Choice D reason: While sterile precautions are taken, there is still a risk of infection with any catheter.
Correct Answer is B
Explanation
Choice A reason: Diagnosis is the identification of a disease or condition, which is not directly related to reviewing kidney function test data.
Choice B reason: Assessment involves collecting and analyzing data, which is what the nurse is doing when reviewing kidney function test results.
Choice C reason: Implementation refers to carrying out interventions, not reviewing test data.
Choice D reason: Outcomes identification involves setting goals and expected outcomes, not reviewing test data.
