Question 1: A nurse is preparing to administer a medication that 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 between doses
for extended periods. A drug with a half-life of 4 days would sustain therapeutic plasma
concentration with once-daily dosing .
Question 2: A nurse is reviewing factors that influence medication metabolism.
Which factor should the nurse identify as a reason to administer a lower
medication dosage?
A. Increased renal secretion
B. Increased medication-metabolizing enzymes
C. Liver failure
D. Peripheral vascular disease
CORRECT ANSWER: C. Liver failure
Rationale: Liver failure decreases metabolism, leading to increased medication
concentration in the body and requiring dosage reduction to prevent toxicity .
Question 3: A nurse is preparing to administer eye drops to a client. Which
action should the nurse take?
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 drops enter the eye
D. Drop medication into the center of the conjunctival sac
CORRECT ANSWER: B. Ask the client to look up at the ceiling
Rationale: Looking upward prevents drops from falling directly onto the cornea and
promotes proper distribution of the medication into the conjunctival sac .
Question 4: A nurse is completing discharge teaching for a client with a new
prescription for transdermal patches. Which statement indicates 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: Hairless areas promote optimal medication absorption. Sites should be
rotated to prevent skin irritation and the new patch should not be placed on the same
site as the old patch .
Question 5: A nurse is reviewing a client's medical record and notes a
prescription for verifying a trough level. Which action should the nurse take?
A. Obtain a blood specimen immediately prior to administering the next dose
B. Verify the client has been taking the medication for 24 hours before obtaining
specimen
C. Ask the client to provide a urine specimen after the next dose
D. Administer the medication and obtain a blood specimen 30 minutes later
CORRECT ANSWER: A. Obtain a blood specimen immediately prior to
administering the next dose
Rationale: Trough levels are obtained immediately before the next scheduled dose to
measure the lowest concentration of the medication in the bloodstream .
Question 6: A nurse is preparing a client's medications. Which action should
the nurse take to verify the client's identity?
A. Ask the client to state their name and date of birth
B. Check the client's room number
C. Verify the client's name on the medication administration record
D. Ask the client's family member to confirm identity
CORRECT ANSWER: A. Ask the client to state their name and date of birth
Rationale: The nurse should use two patient identifiers, typically name and date of birth,
as stated by the patient to ensure medication safety .
,Question 7: A nurse is administering a medication via nasogastric tube. Which
action should the nurse take first?
A. Flush the tube with 30 mL of water
B. Verify tube placement
C. Crush the medication
D. Administer the medication in divided doses
CORRECT ANSWER: B. Verify tube placement
Rationale: The nurse must first verify the NG tube placement by aspiration or x-ray
confirmation before administering any medication through the tube .
Question 8: The client has begun medication therapy with pancrelipase
(Pancrease MT). The nurse evaluates that the medication is having the optimal
intended benefit if which effect is observed?
A. Weight loss
B. Relief of heartburn
C. Reduction of steatorrhea
D. Absence of abdominal pain
CORRECT ANSWER: C. Reduction of steatorrhea
Rationale: Pancrelipase is a pancreatic enzyme used in clients with pancreatitis as a
digestive aid. The medication should reduce the amount of fatty stools (steatorrhea) by
improving fat digestion .
Question 9: An older client recently has been taking cimetidine (Tagamet). The
nurse monitors the client for which most frequent central nervous system side
effect of this medication?
A. Tremors
B. Dizziness
C. Confusion
D. Hallucinations
CORRECT ANSWER: C. Confusion
Rationale: Cimetidine is an H2-receptor antagonist. Older clients are especially
susceptible to central nervous system side effects, with confusion being the most
frequent manifestation .
Question 10: The client with a gastric ulcer has a prescription for sucralfate
(Carafate), 1 g by mouth four times daily. The nurse schedules the medication
for which times?
A. With meals and at bedtime
B. Every 6 hours around the clock
C. One hour after meals and at bedtime
D. One hour before meals and at bedtime
, CORRECT ANSWER: D. One hour before meals and at bedtime
Rationale: Sucralfate should be administered one hour before meals and at bedtime to
allow the medication to form a protective barrier over the ulcer before food intake .
Question 11: A nurse is preparing to administer a medication that 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 between doses
for extended periods. The nurse should expect to administer this medication once daily .
Question 12: A staff educator is reviewing factors that influence medication
metabolism. Which factor should the educator include as a reason to
administer lower medication dosages?
A. Increased renal secretion
B. Increased medication-metabolizing enzymes
C. Liver failure
D. Peripheral vascular disease
CORRECT ANSWER: C. Liver failure
Rationale: Liver failure decreases metabolism, increasing medication concentration and
requiring dosage reduction to prevent toxicity .
Question 13: A nurse is preparing to administer eye drops to a client. Which
actions should the nurse take?
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 drops enter the eye
D. Drop medication into the center of the conjunctival sac
CORRECT ANSWER: B. Ask the client to look up at the ceiling
Rationale: Looking upward prevents drops from falling onto the cornea. The center of
the conjunctival sac promotes distribution of the medication .
Question 14: A nurse is completing discharge teaching for a client with a new
prescription for transdermal patches. Which statement indicates 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."
