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 ["B","D","E"]

Explanation

Choice A reason: Driving restrictions are not typically necessary for clients on hemodialysis unless there are other underlying conditions affecting their ability to drive safely.

Choice B reason: Clients on hemodialysis need to restrict foods high in potassium, sodium, and phosphorus to manage their electrolyte levels and prevent complications.

Choice C reason: Airplane travel is not generally restricted for hemodialysis clients, but they may need to arrange for dialysis at their destination.

Choice D reason: Time constraints are a significant factor as hemodialysis requires several hours per session, multiple times a week.

Choice E reason: Fluid intake often needs to be restricted in clients on hemodialysis to prevent fluid overload, as the kidneys are not able to remove excess fluid effectively.

Choice F reason: Limiting social activities is not a necessary restriction unless it is related to the client's overall health status.

A. "A low-protein diet will reduce the risk for hyperkalemia." B. "A low-protein diet reduces the risk for uremia." C. "A low-protein diet reduces the risk for edema." D. "A low-protein diet will decrease the nitrogenous waste in the blood."

Correct Answer is B

Explanation

Choice A reason: While a low-protein diet can help manage electrolyte imbalances, it is not specifically targeted at reducing the risk for hyperkalemia. Hyperkalemia is more directly managed by restricting foods high in potassium.

Choice B reason: A low-protein diet helps reduce the risk for uremia, which is the accumulation of waste products in the blood due to impaired kidney function. By consuming less protein, there is less urea and other nitrogenous wastes for the kidneys to filter, which can help delay the progression of kidney disease.

Choice C reason: Edema is related to ﬂuid retention and not directly to protein intake. A low-protein diet does not specifically reduce the risk for edema unless it is associated with kidney dysfunction aﬀecting ﬂuid balance.

Choice D reason: A low-protein diet will indeed decrease the amount of nitrogenous waste in the blood because less protein breakdown means less waste for the kidneys to remove. However, this choice is less specific than Choice B, which directly addresses the condition of uremia that is a concern for patients with chronic kidney failure.
