A nurse in the emergency department is caring for a client who collapsed after playing football on a hot day. After reviewing the admission laboratory findings, the nurse recognizes that these findings are consistent with which of the following conditions?

Renal failure

Low-protein diet

Dehydration

Syndrome of inappropriate antidiuretic hormone (SIADH)

Answer and Explanation

The Correct Answer is C

Choice A reason: Renal failure is typically associated with abnormal creatinine and BUN levels, which are not

indicated in the given lab values.

Choice B reason: A low-protein diet is not directly indicated by the lab values provided and does not typically result in

collapse after exertion.

Choice C reason: Dehydration is consistent with the client's history of collapsing after playing football on a hot day

and is supported by the elevated sodium level.

Choice D reason: SIADH usually presents with low sodium levels due to dilution, which is not the case here.

Correct Answer is A

Explanation

Choice A reason: Acute tubular necrosis (ATN) is a condition where there is damage to the renal tubular cells, which can lead to a decrease in GFR. This is because the tubular cells are responsible for reabsorbing substances from the filtrate back into the blood. When these cells are injured, they cannot function properly, leading to a buildup of waste products and a decrease in GFR.

Choice B reason: While obstruction can lead to a decrease in GFR, it is not the primary cause in the context of acute tubular necrosis. Obstruction typically occurs in postrenal causes of acute kidney injury.

Choice C reason: In?ammatory cells do invade damaged kidneys, but this is more characteristic of conditions such as acute interstitial nephritis rather than ATN. In ATN, the primary issue is the injury to the tubular cells themselves.

Choice D reason: A reduction of blood flow to the kidneys, or prerenal azotemia, can indeed lead to a decrease in GFR. However, in the context of ATN, the primary issue is not the blood flow but the damage to the renal tubules.

A. "The volume of the output solution should be greater than the input solution." B. "The fluid from my abdomen will be clear or slightly yellow." C. "The microwave in my kitchen can warm the solution before I use it." D. "The catheter can become infected even with sterile precautions."

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.
