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.
