Opioids such as morphine are used to relieve moderate to severe pain in cancer patients.
Choice A is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that may be used to relieve mild pain, not moderate pain.
Choice C is wrong because acetaminophen may be used to relieve mild pain, not moderate pain.
Choice D is wrong because aspirin is an NSAID that may be used to relieve mild pain, not moderate pain.
Correct Answer is B
Explanation
Step 1: Convert weight from lb to kg.
88 lb ÷ 2.2 = 40 kg
Step 2: Calculate total daily dose in mg.
150 mg/kg × 40 kg = 6000 mg
Step 3: Calculate dose per administration (every 6 hr).
6000 mg ÷ 4 = 1500 mg
Step 4: Calculate number of tablets per dose.
1500 mg ÷ 500 mg/tab = 3 tablets
Answer:
3 tablets per dose.
