Correct Answer is B
Explanation
A. Administer the medication subcutaneously – Diazepam should be given orally or intravenously in severe cases, not subcutaneously.
B. Initiate seizure precautions – This is the correct answer. Alcohol withdrawal can lead to seizures due to central nervous system hyperactivity. Diazepam, a benzodiazepine, is used to prevent seizures and manage withdrawal symptoms.
C. Administer the medication with an antacid – There is no need to administer diazepam with an antacid; doing so can interfere with absorption.
D. Initiate contact precautions – Alcohol withdrawal is not an infectious condition, so contact precautions are unnecessary.
Correct Answer is A
Explanation
A. This is the correct answer. Older adults are at risk for fluid overload, so infusing blood over 4-5 hours (instead of the usual 2-4 hours) is safer.
B. Blood products must be infused with 0.9% sodium chloride (normal saline) only. Dextrose-containing solutions cause hemolysis.
C. A 20-gauge catheter is acceptable, but a larger bore (18-gauge) is preferred for faster infusion.
D. Vital signs should be monitored before the transfusion, 15 minutes after starting, then every 30-60 minutes, and at completion.
