Introduction
*The purpose of this assessment is to evaluate the student's mastery of pharmacological
principles essential for safe and effective nursing practice. This exam measures the ability to
synthesize knowledge regarding drug actions, interactions, and the complexities of
medication administration across diverse clinical populations. Through a series of multiple-
choice and scenario-based questions, candidates must demonstrate high-level critical
thinking, clinical judgment, and adherence to safety protocols. Emphasis is placed on the
application of pharmacological theory to real-world patient care, ensuring practitioners can
effectively manage medications, anticipate adverse outcomes, and promote optimal
therapeutic results in accordance with professional nursing standards.*

bradycardia.
Question 2 A nurse is caring for a client who is receiving intravenous heparin. Which of the
following laboratory values should the nurse monitor to evaluate the effectiveness of the
,therapy? A. Prothrombin time (PT) B. International normalized ratio (INR) C. Activated partial
thromboplastin time (aPTT) D. Platelet count
C. Activated partial thromboplastin time (aPTT) Explanation: The aPTT is the

Question 3 A client is prescribed lisinopril for the treatment of hypertension. Which of the
following side effects should the nurse instruct the client to report immediately? A. Dry
cough B. Angioedema C. Headache D. Fatigue
B. Angioedema Explanation: Angioedema is a serious, life-threatening adverse effect
of ACE inhibitors like lisinopril that involves swelling of the face, lips, and tongue, potentially
leading to airway obstruction.
Question 4 A nurse is administering morphine sulfate to a client with severe pain. Which of
the following findings is the priority assessment? A. Respiratory rate B. Blood pressure C.
Urine output D. Level of consciousness
A. Respiratory rate Explanation: Morphine is an opioid analgesic that causes central
nervous system depression, making respiratory depression the most significant and
potentially fatal adverse effect.
Question 5 A client is prescribed levothyroxine for hypothyroidism. Which of the following
statements by the client indicates an understanding of the medication teaching? A. I should
take this medication with breakfast. B. I will need to take this medication for only a few
months. C. I should take this medication on an empty stomach in the morning. D. I will stop
taking the medication if I feel palpitations.
C. I should take this medication on an empty stomach in the morning. Explanation:
Levothyroxine absorption is significantly increased when taken on an empty stomach, at
least 30 to 60 minutes before breakfast.
Question 6 A nurse is caring for a client who is taking warfarin. Which of the following
medications should the nurse clarify with the provider? A. Acetaminophen B. Aspirin C.
Diphenhydramine D. Calcium carbonate
B. Aspirin Explanation: Aspirin is an antiplatelet agent that significantly increases the
risk of bleeding when combined with anticoagulants like warfarin.
Question 7 A client is prescribed albuterol via a metered-dose inhaler. Which of the
following actions indicates the client is using the device correctly? A. The client holds their
breath for 10 seconds after inhalation. B. The client exhales forcefully after inhaling the
medication. C. The client shakes the inhaler after removing the cap. D. The client takes the
medication immediately after a meal.
, A. The client holds their breath for 10 seconds after inhalation. Explanation: Holding
the breath for 10 seconds after inhaling albuterol allows the medication to settle in the
airways, maximizing its therapeutic effect.
Question 8 A nurse is administering vancomycin to a client. Which of the following findings
should the nurse identify as a potential sign of "red man syndrome"? A. Hypotension and
flushing of the face and neck B. Severe diarrhea C. Jaundice and elevated liver enzymes D.
Tinnitus and hearing loss
A. Hypotension and flushing of the face and neck Explanation: Red man syndrome is
an adverse effect associated with rapid infusion of vancomycin, characterized by flushing,
pruritus, and hypotension.
Question 9 A nurse is teaching a client about the use of nitroglycerin patches. Which of the
following instructions is appropriate? A. Apply the patch to a hairy area to ensure it stays in
place. B. Rotate the application sites to prevent skin irritation. C. Keep the patch on for 24
hours every day. D. Apply the patch to the chest only.
B. Rotate the application sites to prevent skin irritation. Explanation: Rotating sites is
necessary to prevent local skin irritation and to ensure consistent absorption of the
medication.
Question 10 A nurse is preparing to administer insulin glargine to a client. Which of the
following characteristics is true regarding this type of insulin? A. It has a peak effect in 2
hours. B. It is a rapid-acting insulin. C. It is a long-acting insulin with no defined peak. D. It
should be mixed with regular insulin in the same syringe.
C. It is a long-acting insulin with no defined peak. Explanation: Insulin glargine
provides a constant basal level of insulin throughout the day and does not have a
pronounced peak, which reduces the risk of hypoglycemia.
Question 11 A nurse is caring for a client receiving gentamicin. Which of the following
findings should the nurse monitor as an indication of ototoxicity? A. Blurred vision B.
Tinnitus C. Urinary retention D. Dyspnea
B. Tinnitus Explanation: Gentamicin is an aminoglycoside antibiotic known to cause
ototoxicity, and tinnitus (ringing in the ears) is often the first clinical manifestation.
Question 12 A nurse is providing discharge instructions for a client taking spironolactone.
Which of the following should the nurse include? A. Increase intake of salt substitutes. B.
Avoid potassium-rich foods. C. Take the medication at bedtime. D. Monitor for signs of
dehydration.
B. Avoid potassium-rich foods. Explanation: Spironolactone is a potassium-sparing
diuretic; consuming high-potassium foods increases the risk of hyperkalemia.
, Question 13 A nurse is administering phenytoin to a client. Which of the following
assessment findings is an expected side effect? A. Gingival hyperplasia B. Excessive hair
growth C. Weight loss D. Polyuria
A. Gingival hyperplasia Explanation: Gingival hyperplasia (overgrowth of gum tissue)
is a common adverse effect associated with long-term phenytoin therapy, necessitating
meticulous oral hygiene.
Question 14 A nurse is monitoring a client receiving furosemide. Which of the following
electrolyte imbalances should the nurse watch for? A. Hyperkalemia B. Hyponatremia C.
Hypercalcemia D. Hypomagnesemia
D. Hypomagnesemia Explanation: Furosemide is a loop diuretic that promotes the
excretion of potassium, sodium, and magnesium, putting the client at risk for
hypomagnesemia.
Question 15 A nurse is caring for a client who is prescribed methotrexate. Which of the
following instructions should the nurse provide? A. Avoid contact with people who have
infections. B. Take the medication with a glass of milk. C. Monitor for decreased appetite. D.
Increase intake of vitamin C.
A. Avoid contact with people who have infections. Explanation: Methotrexate is an

to pathogens.
Question 16 A nurse is teaching a client about clopidogrel. Which of the following
statements by the client indicates an understanding of the medication? A. I will take this
medication on an empty stomach. B. I will monitor for unusual bruising or bleeding. C. I will
stop the medication if I develop a headache. D. I will avoid taking this medication with
grapefruit juice.
B. I will monitor for unusual bruising or bleeding. Explanation: Clopidogrel is an
antiplatelet medication that increases the risk of bleeding; clients should be educated to
monitor for signs of hemorrhage.
Question 17 A nurse is administering lorazepam to a client who is having a panic attack.
Which of the following is the priority intervention? A. Monitor the client's blood pressure. B.
Keep the client in a quiet, low-stimulus environment. C. Ensure the client has adequate
hydration. D. Administer a sedative-hypnotic as needed.
