Medication Administration & IV Therapy
63. Phenobarbital Half-Life
Question: 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
CORRECT ANSWER: A. One
Rationale: Medications with long half-lives remain at therapeutic levels for extended periods.
Therefore, phenobarbital with a half-life of 4 days can be administered once daily.
64. Factors Requiring Lower Medication Dosages
Question: A staff educator is reviewing medication dosages and factors that influence
medication metabolism with a group of nurses at an in-service presentation. Which of the
following factors should the educator include as a reason 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
, CORRECT ANSWERS:
C. Liver failure
E. Concurrent use of medication the same pathway metabolizes
Rationale: Liver failure decreases medication metabolism, which can increase drug
concentrations and require a lower dose. When two medications use the same metabolic
pathway, they can compete for metabolism and increase medication concentrations.
65. Administration of Eye Drops
Question: A nurse is preparing to administer eye drops to a client. Which of the following
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.
C. Tell the client to blink when the drops enter her eye.
D. Drop the medication into the center of the client's conjunctival sac.
E. Instruct the client to close her eye gently after instillation.
CORRECT ANSWERS:
B. Ask the client to look up at the ceiling.
D. Drop the medication into the center of the client's conjunctival sac.
E. Instruct the client to close her eye gently after instillation.
Rationale: Looking upward helps keep the medication from falling directly onto the cornea. The
medication should be placed in the conjunctival sac, and the client should gently close the eye
to distribute the medication.
66. Transdermal Patches
Question: A nurse is completing discharge teaching for a client who has a new prescription for
transdermal patches. Which of the following statements should the nurse identify as an
indication that the client understands the instructions?
A. "I will clean the site with an alcohol swab before I apply the patch."
B. "I will rotate the application sites weekly."
C. "I will apply the patch to an area of skin with no hair."
D. "I will place the new patch on the site of the old patch."
CORRECT ANSWER: C. "I will apply the patch to an area of skin with no hair."
, Rationale: A transdermal patch should be applied to a hairless area to promote appropriate
medication absorption.
67. Trough Medication Level
Question: A nurse reviewing a client's medical record notes a new prescription for verifying the
trough level of the client's medication. Which of the following actions should the nurse take?
A. Obtain a blood specimen immediately prior to administering the next dose of medication.
B. Verify that the client has been taking the medication for 24 hr before obtaining a blood
specimen.
C. Ask the client to provide a urine specimen after the next dose of medication.
D. Administer the medication, and obtain a blood specimen 30 min late.
CORRECT ANSWER: A. Obtain a blood specimen immediately prior to administering the
next dose of medication.
Rationale: A trough level represents the lowest concentration of medication in the bloodstream
and is obtained immediately before the next scheduled dose.
68. Legal Responsibilities When Preparing Medications
Question: A nurse is preparing a client's medications. Which of the following actions should the
nurse take in following legal practice guidelines? (Select all that apply.)
A. Maintain skill competency.
B. Determine the dosage.
C. Monitor for adverse effects.
D. Safeguard medications.
E. Identify the client's diagnosis.
CORRECT ANSWERS:
A. Maintain skill competency.
C. Monitor for adverse effects.
D. Safeguard medications.
Rationale: Nurses have legal responsibilities to maintain competency, monitor clients for
adverse medication effects, and safeguard medications, including controlled substances.
