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

Correct Answer is A

Explanation

A. Grapes and walnut chicken salad sandwich on whole wheat bread. Whole wheat bread and grapes are rich in fiber, which promotes regular bowel movements and prevents constipation.

B. Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing. This meal lacks sufficient fiber. Cheese and eggs can contribute to constipation.

C. Broccoli and cheese soup with potato bread. While broccoli has fiber, the cheese and potato bread are low in fiber and may contribute to constipation.

D. Turkey and mashed potatoes with brown gravy. This meal is low in fiber, and gravy can be high in fat, which may slow digestion.

A. RBC 4.9 mm3 B. Serum potassium 4.0 mEq/L C. Serum creatinine 0.8 mg/dL D. BUN 100 mg/dL

Correct Answer is D

Explanation

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.
