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

Explanation

Choice A reason: The pH of urine can vary, but having a more alkalotic urine does not necessarily promote the growth of bacteria. Urine is typically slightly acidic, which helps to prevent bacterial growth.

Choice B reason: The primary anatomical reason for the higher rates of UTIs in clients who have vaginas is the shorter length of the urethra compared to those who do not have vaginas. This shorter distance makes it easier for bacteria from the skin or rectal area to enter the bladder.

Choice C reason: The strength of the detrusor muscle, which controls the emptying of the bladder, does not have a direct correlation with the frequency of UTIs. UTIs are more related to bacterial invasion rather than muscle strength.

Choice D reason: Bladder capacity is generally not a factor in the frequency of UTIs. While residual urine can increase the risk of UTIs, this is not typically related to overall bladder capacity.

A. "The kidney infection has caused narrowing of the ureters, and your abdomen has filled with fluid." B. "The kidneys continue to enlarge due to the cysts growing, which increases the girth of your abdomen." C. "The stones might descend into the ureters, blocking the flow of urine and causing an increase in the girth of your abdomen." D. "The in?ammation in your kidneys damages the filtration system, which causes fluid retention in your abdomen."

Correct Answer is B

Explanation

Choice A reason: While kidney infections can cause swelling, they typically do not lead to a significant increase in abdominal girth unless associated with severe obstruction or advanced kidney disease.

Choice B reason: In PKD, the kidneys can become significantly enlarged due to the growth of numerous cysts, which

can indeed lead to an increase in abdominal girth.

Choice C reason: While stones can cause blockage and swelling, they would not typically result in a generalized increase in abdominal girth unless there is an associated infection or severe obstruction.

Choice D reason: Inflammation can lead to fluid retention, but in the context of PKD, it is the cysts' growth that primarily contributes to increased kidney size and abdominal girth.
