A nurse is reviewing the laboratory values of a client who has chronic glomerulonephritis. Which of the following is an expected finding for this client?

RBC 4.9 mm3

Serum potassium 4.0 mEq/L

Serum creatinine 0.8 mg/dL

BUN 100 mg/dL

Answer and Explanation

The Correct Answer is D

A. RBC 4.9 mm³: Chronic glomerulonephritis often leads to anemia due to decreased erythropoietin production, so a normal RBC count is unexpected.

B. Serum potassium 4.0 mEq/L : Kidney disease often leads to hyperkalemia (K⁺ >5.0 mEq/L) due to impaired potassium excretion.

C. Serum creatinine 0.8 mg/Dl: Chronic kidney disease results in increased creatinine levels (>1.3 mg/dL) due to reduced glomerular filtration.

D. BUN 100 mg/dL: BUN (Blood Urea Nitrogen) is elevated in kidney dysfunction. Normal BUN is 6–20 mg/dL, and a BUN of 100 mg/dL suggests severe renal impairment.

Correct Answer is D

Explanation

A. A 5-year-old child who ignores the urge to defecate owing to embarrassment. Ignoring the urge to defecate slows peristalsis, leading to constipation.

B. A 40-year-old female with major depressive disorder. Depression is more likely to cause decreased peristalsis and constipation.

C. An 80-year-old male in an assisted-living environment. Aging typically slows peristalsis, leading to constipation.

D. A 21-year-old female with three final examinations on the same day. Stress and anxiety stimulate the sympathetic nervous system, increasing peristalsis and leading to diarrhea.

A. Abdominal distention B. Request for a cup of tea and some toast C. Hypoactive bowel sounds in two quadrants D. Passage of flatus

Correct Answer is D

Explanation

A. Abdominal distention. Distention is more indicative of a paralytic ileus or gas buildup, not return of peristalsis.

B. Request for a cup of tea and some toast. While appetite may return as peristalsis resumes, it is not a definitive sign.

C. Hypoactive bowel sounds in two quadrants. Hypoactive sounds suggest minimal bowel activity, not full peristalsis.

D. Passage of flatus. Passing gas is a key sign that peristalsis is returning postoperatively.
