A nurse counsels a patient with a new prescription for interferon beta-1a, 30 mcg, given intramuscularly once a week. What time of day would be best for the patient to administer the drug?
a. 0730
b. 1200
c. 1800
d. 2200
D
Injections of interferon beta-1a should be given late in the day so that flulike symptoms occur during sleep.
Administering the medication at 0730 would be a poor choice, because the patient may expe-rience flulike symptoms throughout the day.
Administering the medication at either 1200 or 1800 so that it can be given with food is irrele-vant, because the drug is administered intramuscularly.
