A nurse is reviewing the laboratory reports of a client who is undergoing nutritional screening due to a risk for chronic kidney disease. The nurse should identify that which of the following results indicates the need for further assessment?
Serum creatinine 3.5 mg/dL
Hematocrit 45%
Blood urea nitrogen 18 mg/dL
Sodium 140 mEq/L
The Correct Answer is A
Choice A reason: Serum creatinine 3.5 mg/dL is high and indicates the need for further assessment. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.
Choice B reason: Hematocrit 45% is within the normal range (37-47% for women, 40-50% for men), and it does not indicate the need for further assessment. Hematocrit is the percentage of red blood cells in the blood. Low hematocrit levels can indicate anemia, bleeding, or hemolysis.
Choice C reason: Blood urea nitrogen 18 mg/dL is within the normal range (7-20), and it does not indicate the need for further assessment. Blood urea nitrogen is a waste product of protein metabolism that is filtered by the kidneys. High blood urea nitrogen levels can indicate dehydration, kidney damage, or high protein intake.
Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate the need for further assessment. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. Low or high sodium levels can cause confusion, seizures, or coma.

Correct Answer is A
Explanation
Choice A reason: Flushing the tubing with water every 4 hours can prevent the tubing from clogging by clearing any residual formula or medication from the lumen.
Choice B reason: Replacing the bag and tubing every 24 hours can prevent bacterial contamination, but it does not prevent the tubing from clogging.
Choice C reason: Administering the feeding by gravity drip can cause overfeeding, aspiration, or diarrhea, but it does not prevent the tubing from clogging.
Choice D reason: Heating the formula prior to infusion can cause bacterial growth, nutrient loss, or burns, but it does not prevent the tubing from clogging.
Correct Answer is D
Explanation
Choice A reason: The client's creatinine level of 1.0 mg/dL is within the normal range (0.6-1.2), but it does not indicate the effectiveness of the treatment for benign prostatic hyperplasia. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.
Choice B reason: The client's urine output of 35 mL/hr is below the normal range (40-60), and it indicates the need for further assessment. Low urine output can indicate dehydration, urinary retention, or kidney failure.
Choice C reason: The client's stool consistency and color are not related to the treatment for benign prostatic hyperplasia. Soft, brown stool is normal and does not indicate any problem with the digestive system.
Choice D reason: The client's ability to urinate without straining indicates that the treatment for benign prostatic hyperplasia has been effective. Benign prostatic hyperplasia is a condition in which the prostate gland enlarges and compresses the urethra, causing difficulty in urination. Treatment options include medication, surgery, or minimally invasive procedures to reduce the size of the prostate and relieve urinary obstruction.
