The physician orders acetaminophen (Tylenol) for a client with a fever. The nurse would plan to validate which other order with the physician?
1. Heparin 5,000 units subcutaneously every 8 hours
2. Warfarin (Coumadin) 2 mg orally every day
3. Penicillin G benzathine (Bicillin LA) 2.4 million units IM one time
4. Paroxetine (Paxil) 37.5 mg orally every day
Correct Answer: 2
Rationale 1: There is no contraindication to the use of heparin and acetaminophen (Tylenol).
Rationale 2: Acetaminophen (Tylenol) inhibits warfarin (Coumadin) metabolism. Concomitant use of these two medications could result in a toxic accumulation of warfarin (Coumadin).
Rationale 3: There is no contraindication to the use of penicillin G benzathine (Bicillin LA) and acetaminophen (Tylenol).
Rationale 4: There is no contraindication to the use of paroxetine (Paxil) and acetaminophen (Tylenol).
