A nurse is reinforcing teaching with a client who is to collect stool at home for a fecal occult blood test (FOBT). Which of the following should the nurse instruct the client to avoid for at least 3 days before the test?
Magnesium hydroxide
Orange juice
Whole grain cereal
Acetaminophen
The Correct Answer is C
A. Magnesium hydroxide: Although it is a laxative, it doesn't directly interfere with the chemical detection of blood in the stool.
B. Orange juice: Not known to interfere with guaiac-based FOBT results.
C. Whole grain cereal: High-fiber foods, including whole grains, may irritate the GI tract and cause minor bleeding, leading to a false-positive FOBT.
D. Acetaminophen: Unlike NSAIDs, acetaminophen does not increase the risk of GI bleeding, so it's generally safe.

Correct Answer is ["1","140"]
Explanation
4 oz soda = 120 mL
12 oz water = 360 mL
8 oz gelatin = 240 mL
4 oz broth = 120 mL
IV fluid = 300 mL
Toast is solid and does not count.
Total: 120 + 360 + 240 + 120 + 300 = 1,140 mL
Final intake = 1,140 mL
Correct Answer is B
Explanation
A. Promote active range-of-motion activities: Although helpful, active walking or aerobic activity is more effective than ROM exercises for bowel stimulation.
B. Add fluid and fiber to the diet: Adequate hydration and dietary fiber soften stool and promote regular bowel movements.
C. Avoid gas-producing foods: This might reduce discomfort but does not treat constipation directly.
D. Request that the provider prescribe a stool softener: Non-pharmacological interventions (like diet changes) are first-line unless ineffective.
