A nurse is teaching a client about foods to avoid before having an occult blood test of the stool. Which of the following foods should the nurse instruct the client to avoid?
Potatoes
Red meat
Yogurt
Apples
The Correct Answer is B
Choice A reason: Potatoes do not contain substances that cause false-positive occult blood tests. They are low in heme and do not mimic blood in stool, making them safe to consume before testing.
Choice B reason: Red meat contains heme, which can cause false-positive results in occult blood tests by mimicking blood. Avoiding red meat for 48–72 hours ensures test accuracy, making this the correct choice.
Choice C reason: Yogurt lacks heme or oxidizing agents that interfere with occult blood tests. It is a safe food choice before testing, as it does not affect results, making this incorrect.
Choice D reason: Apples do not typically cause false positives, though some fruits with peroxidase (e.g., turnips) might. Apples are generally safe, making this less critical to avoid than red meat.

Correct Answer is B
Explanation
Choice A reason: 2 mL provides 2 mg (5 mg/5 mL = 1 mg/mL, so 2 mL = 2 mg), which is half the ordered 4 mg. This underdoses the patient, making it incorrect for the prescribed dosage.
Choice B reason: Diazepam 5 mg/5 mL means 1 mg/mL. For 4 mg, 4 mL is needed (4 mg ÷ 1 mg/mL = 4 mL). This delivers the correct dose, making 4 mL the correct answer.
Choice C reason: 5 mL delivers 5 mg (5 mg/5 mL), exceeding the ordered 4 mg. This overdoses the patient, risking sedation, making 5 mL incorrect for the prescribed dosage.
Choice D reason: 6 mL delivers 6 mg, significantly exceeding the 4 mg order. This overdose increases side effects like respiratory depression, making 6 mL incorrect for the correct dosage.
Correct Answer is C
Explanation
Choice A reason: Clear drainage may be serous and normal post-laminectomy, but cerebrospinal fluid leakage is a complication. Numbness is more urgent, indicating a neurological issue, making this less immediate.
Choice B reason: Muscle spasms are common post-laminectomy due to surgical irritation but are less critical than neurological deficits. Numbness suggests nerve compromise, making spasms a lower priority.
Choice C reason: Numbness in the lower extremities indicates potential nerve compression or injury, a serious complication requiring immediate reporting. This could signal hematoma or misalignment, making this the priority finding.
Choice D reason: Incision pain is expected post-laminectomy and manageable with analgesics. Numbness is a neurological red emergency flag, making pain less urgent for immediate reporting.
