A nurse is providing dietary teaching to a client about sources of protein. The nurse should identify which of the following foods are complete proteins?

Choice A reason: The client's creatinine level of 1.0 mg/dL is within the normal range, but it does not indicate that the treatment for benign prostatic hyperplasia has been effective. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys and excreted in urine. It reflects the kidney function, not the prostate condition.

Choice B reason: The client's urine output of 35 mL/hr is below the normal range, which is 40 to 60 mL/hr. This indicates that the client may have dehydration, kidney impairment, or urinary retention, which are complications of benign prostatic hyperplasia. A low urine output does not indicate that the treatment has been effective.

Choice C reason: The client's stool color and consistency are not related to the treatment for benign prostatic hyperplasia. Stool characteristics depend on various factors, such as diet, medication, and bowel function. A soft, brown stool does not indicate that the treatment has been effective.

Choice D reason: The client's ability to urinate without straining is a sign 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. A treatment that reduces the size of the prostate or relaxes the bladder neck muscles can improve the urine flow and reduce the straining.

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.
