NUR 210 FINAL EXAM
PHARMACOLOGY STUDY GUIDE
QUESTIONS & ANSWERS (GALEN) 100%
GUARANTEE PASS
1. A patient is prescribed a medication that is known to be a potent inducer of the hepatic
CYP450 enzyme system. How should the nurse anticipate this will affect other medications
metabolized by the same system?
A. The therapeutic effect of other medications will be reduced.
B. The half-life of other medications will increase.
C. The plasma concentration of other medications will rise to toxic levels.
D. The absorption rate of other medications will decrease in the small intestine.
Answer: A
Conceptual Explanation: Enzyme inducers speed up the metabolism of other drugs
processed by the same enzyme system, leading to lower plasma levels and reduced
therapeutic effectiveness.
2. Which laboratory value is most critical for a nurse to monitor in a patient receiving
Furosemide (Lasix) to prevent Digoxin toxicity?
A. Serum Sodium
,B. Serum Potassium
C. Serum Calcium
D. Serum Magnesium
Answer: B
Conceptual Explanation: Hypokalemia (low potassium) significantly increases the risk of
Digoxin toxicity. Furosemide is a loop diuretic that causes potassium wasting.
3. A patient is receiving Vancomycin via IV infusion. The nurse notes the patient’s face and
neck have become flushed and red. What is the priority nursing action?
A. Slow the infusion rate and monitor the patient.
B. Stop the infusion immediately and notify the provider.
C. Administer an immediate dose of Epinephrine.
D. Apply cold compresses to the affected areas.
Answer: A
Conceptual Explanation: Red Man Syndrome is a rate-dependent infusion reaction, not a
true allergy. The priority is to slow the infusion rate. Stopping is only necessary if it
progresses to anaphylaxis.
4. What is the specific antidote for a patient experiencing a life-threatening overdose of
Heparin?
A. Vitamin K
, B. Glucagon
C. Acetylcysteine
D. Protamine Sulfate
Answer: D
Conceptual Explanation: Protamine sulfate is the specific antagonist for heparin. Vitamin
K is for Warfarin; Glucagon is for Beta-blockers; Acetylcysteine is for Acetaminophen.
5. A patient with a history of asthma is diagnosed with hypertension. Which class of
antihypertensives should the nurse question?
A. Calcium Channel Blockers
B. ACE Inhibitors
C. Angiotensin II Receptor Blockers
D. Non-selective Beta Blockers
Answer: D
Conceptual Explanation: Non-selective beta blockers (like Propranolol) block Beta-2
receptors in the lungs, potentially causing bronchoconstriction in patients with asthma.
6. When administering Alendronate (Fosamax) for osteoporosis, which instruction is vital for
patient safety?
A. Sit upright for at least 30 minutes after taking the dose.
B. Take the medication with a full glass of milk.
