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. The nurse should expect to administer this medication once daily.
Question 2: A nurse is reviewing factors that influence medication metabolism.
Which factor should the nurse include 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, increasing medication concentration and
requiring dosage reduction. When two medications compete for the same metabolic
pathway, concentrations also increase, requiring dosage adjustment.
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: D. Drop medication into the center of the conjunctival sac
Rationale: The center of the conjunctival sac promotes distribution. Looking upward
prevents drops from falling onto the cornea, and gentle closure after instillation
promotes distribution without squeezing medication out.
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 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. Room numbers and family confirmation are not acceptable
identifiers.
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: A nurse is caring for a client who has a new prescription for
ergotamine. The nurse should recognize that ergotamine is administered to
treat which condition?
A. Hypertension
B. Migraine headaches
C. Angina pectoris
D. Asthma
CORRECT ANSWER: B. Migraine headaches
Rationale: Ergotamine prevents or stops migraine headaches by blocking alpha-
adrenergic receptors in the cranial peripheral vascular smooth muscle, causing
vasoconstriction of dilated cerebral blood vessels.
Question 9: A nurse is caring for a client who has a new prescription for
amphotericin B. The nurse should plan to monitor the client for which adverse
effect?
A. Hepatotoxicity
B. Nephrotoxicity
C. Cardiotoxicity
D. Neurotoxicity
CORRECT ANSWER: B. Nephrotoxicity
Rationale: Amphotericin B is an antifungal medication used to treat severe fungal
infections; however, it can cause nephrotoxicity. The nurse should monitor the client's
creatinine every 3-4 days and increase fluid intake.
Question 10: A nurse is preparing to administer heparin 8,000 units
subcutaneously every 8 hours. Available is heparin 10,000 units/1 mL. How
many mL should the nurse administer per dose?
, A. 0.5 mL
B. 0.8 mL
C. 1.0 mL
D. 1.2 mL
CORRECT ANSWER: B. 0.8 mL
Rationale: Calculation: (1 mL / 10,000 units) × 8,000 units = 0.8 mL. The nurse should
round to the nearest tenth and use a leading zero.
Question 11: A nurse is providing teaching to a client who has chronic kidney
failure with an AV fistula for hemodialysis and a new prescription for epoetin
alfa. Which therapeutic effect should the nurse include in the teaching?
A. Reduces blood pressure
B. Inhibits clotting of fistula
C. Promotes RBC production
D. Stimulates growth of neutrophils
CORRECT ANSWER: C. Promotes RBC production
Rationale: Epoetin alfa stimulates erythropoiesis in the bone marrow to increase RBC
production and reduce anemia. Anemia is common in clients with chronic kidney failure
because erythropoietin is produced by the kidney.
Question 12: A nurse is caring for a client who has a new prescription for
enalapril. The nurse should monitor the client for which adverse effect?
A. Hypertension
B. Hypotension
C. Hyperkalemia
D. Bradycardia
CORRECT ANSWER: B. Hypotension
Rationale: Enalapril, an angiotensin-converting enzyme (ACE) inhibitor, can cause
hypotension and postural hypotension, especially during the first 3 hours following the
initial dosage.
Question 13: A nurse is caring for a client who has a prescription for
clopidogrel. The nurse should monitor the client for which adverse effect?
A. Insomnia
B. Hypotension
C. Bleeding
D. Hypertension
CORRECT ANSWER: C. Bleeding
