A provider prescribes phenobarbital for a client who has a seizure disorder. The
medication has a long half-life of 4 days. How many times per day should the
nurse expect to administer this medication?
A. One
B. Two
C. Three
D. Four
Answer: A. One
Rationale: Medications with long half-lives remain at therapeutic levels for
longer periods. Phenobarbital should therefore be administered once daily.
A staff educator is reviewing medication dosages and factors that influence
medication metabolism. Which factors should the educator include as reasons
to administer lower medication dosages? (Select all that apply.)
,A. Increased renal secretion
B. Increased medication-metabolizing enzymes
C. Liver failure
D. Peripheral vascular disease
E. Concurrent use of medication the same pathway metabolizes
Answer: C, E
Rationale: Liver failure decreases medication metabolism, increasing drug
concentration. When two medications use the same metabolic pathway, they
compete for metabolism, which can increase the concentration of one or both
medications.
A nurse is preparing to administer eye drops to a client. Which actions should
the nurse take? (Select all that apply.)
A. Have the client lie on her side.
B. Ask the client to look up at the ceiling.
