SECTION 1: FUNDAMENTALS OF NURSING PHARMACOLOGY AND
ADMINISTRATION
Question 1: The nurse answers a patient's call light and finds the patient sitting up in bed and requesting
pain medication. What will the nurse do first?
A. Check the orders and give the patient the requested pain medication
B. Provide comfort measures to the patient
C. Assess the patient's pain and pain level
D. Evaluate the effectiveness of previous pain medications
ANSWER ■: C — Assess the patient's pain and pain level
Explanation: Before administering any pain medication, the nurse must always perform a baseline assessment of
the patient's pain location, quality, and severity (using a standardized pain scale). Assessing first is a core nursing
concept (assessment before intervention) and ensures safe, appropriate care. Checking orders, providing comfort
measures, and evaluating prior doses are important secondary steps, but the priority is a direct assessment.
Question 2: The nurse is preparing to administer a transdermal patch to a patient and finds that the
patient already has a medication patch on his right upper chest. What will the nurse do?
A. Remove the old medication patch and notify the health care provider
B. Apply the new patch without removing the old one
C. Remove the old patch and apply the new one in the same spot
D. Remove the old patch and apply the new patch to a different clean area
ANSWER ■: D — Remove the old patch and apply the new patch to a different clean area
Explanation: To prevent medication overdose, the old patch must be removed before a new transdermal patch is
applied. The new patch must be placed on a different, clean, dry, and intact skin area to prevent localized skin
irritation and ensure consistent, predictable drug absorption. Applying the new patch in the exact same spot or
leaving the old patch on could lead to dermal toxicity or erratic absorption.

Question 3: A patient is complaining of severe pain and has orders for morphine sulfate. The nurse
knows that the route that would give the slowest pain relief is which route?
A. IV (Intravenous)
B. PO (Oral/By Mouth)
C. Subcutaneous
D. IM (Intramuscular)
ANSWER ■: B — PO (Oral/By Mouth)
Explanation: The oral (PO) route is subject to the 'first-pass effect' in the liver and must go through the entire
gastrointestinal tract to be absorbed, which results in the slowest onset of action compared to parenteral routes.
Intravenous (IV) administration has an immediate onset, while intramuscular (IM) and subcutaneous routes bypass GI
absorption and have a faster onset than oral administration.
Question 4: A patient is recovering from an appendectomy. She also has asthma and allergies to shellfish
and iodine. To manage her postoperative pain, the physician has prescribed hydromorphone (Dilaudid).
Which vital sign is of greatest concern?
A. Temperature
B. Respirations
C. Pulse
D. Blood pressure
ANSWER ■: B — Respirations
Explanation: Hydromorphone is a potent opioid agonist that can cause severe respiratory depression. Since the
patient also has a history of asthma, her respiratory status is the paramount concern. The nurse must monitor
respirations closely, as a rate below 12 breaths/minute warrants withholding the medication and potentially
administering a reversal agent (Naloxone). Other vital signs are monitored but are not the immediate physiological
priority.

Question 5: The patient is diagnosed with Parkinson's disease and has been started on a dopaminergic
replacement drug therapy with carbidopa-levodopa. It is important for the nurse to perform which
assessment?
A. Assess the patient for dizziness and syncope when the patient is walking
B. Administer the medication first thing in the morning with high-protein food
C. Administer the medication strictly on an empty stomach to avoid any nausea
D. Remove all protein completely from the patient's diet
ANSWER ■: A — Assess the patient for dizziness and syncope when the patient is walking
Explanation: Carbidopa-levodopa commonly causes orthostatic hypotension, which increases the risk of dizziness,
lightheadedness, syncope, and falls. The nurse should monitor the patient closely during ambulation and instruct
them to change positions slowly. High-protein foods can reduce the absorption of levodopa, so protein should be
distributed evenly throughout the day, not eliminated entirely. While taking it with a small non-protein snack can help
reduce initial GI upset, assessing for safety and falls is the priority.
Question 6: Which drug will the nurse anticipate administering to a patient experiencing an acute
benzodiazepine overdose?
A. Flumazenil
B. Narcan (Naloxone)
C. Methadone
D. Antabuse (Disulfiram)
ANSWER ■: A — Flumazenil
Explanation: Flumazenil is a specific benzodiazepine receptor antagonist that reverses the sedative and
respiratory-depressive effects of benzodiazepines. Narcan (Naloxone) is the reversal agent for opioids. Methadone is
used for opioid maintenance and detoxification. Antabuse (Disulfiram) is used as a deterrent therapy for chronic
alcohol use disorder.

Question 7: Which statement is important for the nurse to include when teaching a patient about
disulfiram (Antabuse) therapy?
A. This medication will cure your alcoholism if you take it as directed
B. This medication will cause your blood pressure to get very high if you drink alcohol after taking it
C. You cannot drink alcohol for at least 3-4 days after taking this medication
D. If you miss a dose of Antabuse, double up the next time it is due to keep levels steady
ANSWER ■: C — You cannot drink alcohol for at least 3-4 days after taking this medication
Explanation: Disulfiram (Antabuse) works by inhibiting the enzyme aldehyde dehydrogenase, causing a severe,
highly unpleasant physical reaction if alcohol is consumed. This effect can persist in the body for up to several days
after the last dose, so the patient must avoid all forms of alcohol (including mouthwash and cough syrups) for at least
3-4 days (and up to 2 weeks). Disulfiram is a deterrent, not a cure, and causes severe hypotension and flushing, not
hypertension, when mixed with alcohol. Missing doses should never be doubled.
Question 8: A patient on a dobutamine drip starts complaining that her IV line 'hurts really bad.' The nurse
on assessing the site notices that it is red, swollen, and cool to the touch. What will the nurse do first?
A. Slow the infusion rate to see if the discomfort resolves
B. Stop the infusion immediately
C. Inject the area immediately with phentolamine
D. Notify the health care provider of the potential infiltration
ANSWER ■: B — Stop the infusion immediately
Explanation: The symptoms (redness, swelling, and coolness to the touch) indicate extravasation of a
vasoactive/vesicant drug (dobutamine). The nurse's absolute first action must be to stop the infusion to prevent
further tissue damage. Slowing the rate or waiting to notify the provider increases the risk of severe tissue necrosis.
Phentolamine is an alpha-blocker used as an antidote for catecholamine extravasation, but the pump must be
stopped first before any local injection or medication is given.
