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: In the oliguric phase of acute kidney injury, the creatinine level is expected to increase, not decrease, due to impaired kidney function and decreased filtration.
Choice B reason: The GFR is expected to decrease in acute kidney injury, not increase, as the kidneys' ability to filter
blood is compromised.
Choice C reason: Hyperkalemia, or high potassium levels in the blood, is a common finding in the oliguric phase of acute kidney injury due to decreased excretion of potassium by the kidneys.
Choice D reason: Hypomagnesemia, or low magnesium levels, is not typically associated with the oliguric phase of acute kidney injury. Instead, hypermagnesemia may occur due to decreased excretion of magnesium.
Correct Answer is B
Explanation
Choice A reason: The bladder is not where renal calculi typically begin to form; it is where they may end up if they travel down from the kidneys.
Choice B reason: Renal calculi commonly begin forming at the renal papilla, which is part of the kidney where urine collects before it flows into the ureter.
Choice C reason: The ureter is not the typical starting point for the formation of renal calculi, though stones can travel through it.
Choice D reason: The urethra is not a common site for the formation of renal calculi; it is the duct through which urine is discharged.
