A nurse is monitoring an older adult female client who had a myocardial infarction (MI) for the development of acute kidney injury (AKI). Which of the following findings should the nurse identify as indicating an increased risk of AKI?

Serum creatinine 1.8 mg/dL

Blood urea nitrogen (BUN) 200 mg/dL

Serum osmolality 290 mOsm/kg H2O

Magnesium 2.0 mEq/L

Answer and Explanation

Correct Answer : A,B

Choice A reason: The normal range for serum creatinine in adult females is approximately 0.6–1.1 mg/dL. A level of 1.8 mg/dL is elevated and indicates impaired kidney function, which is a risk factor for AKI.

Choice B reason: Normal BUN levels are generally between 6 to 24 mg/dL⁸. A BUN level of 200 mg/dL is significantly elevated and suggests kidney dysfunction, which can lead to AKI.

Choice C reason: Serum osmolality in the normal range, which is typically between 275 to 295 mOsm/kg H2O for adults⁹[13][^10^][14][16], does not indicate an increased risk of AKI.

Choice D reason: The normal range for serum magnesium is typically 1.7 to 2.2 mg/dL or 0.85 to 1.10 mmol/L. A level of 2.0 mEq/L (which is equivalent to 2.0 mg/dL) is within the normal range and does not indicate an increased risk for AKI.

Correct Answer is A

Explanation

Choice A reason: Clients with nephrotic syndrome are usually advised to decrease sodium intake to manage edema, not increase it.

Choice B reason: A kidney biopsy may be prescribed to determine the cause of nephrotic syndrome, so this statement does not indicate a need for further teaching.

Choice C reason: Swelling, particularly in the face, is a common symptom of nephrotic syndrome due to fluid retention.

Choice D reason: Losing protein in the urine is a hallmark of nephrotic syndrome, so this statement is accurate.

A. The glomerular filtration rate decreases because there is injury to the renal tubular cells. B. The glomerular filtration rate decreases because there is obstruction leading to the filtration system backing up and eventually shutting the kidneys down. C. The glomerular filtration rate decreases because in?ammatory cells invade the already damaged kidneys. D. The glomerular filtration rate decreases because there is a reduction of blood flow to the kidneys.

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.
