Questions & Verified Answers
1. A patient is prescribed a drug that is a known Cytochrome P450 (CYP450) enzyme inducer.
What effect will this have on a co-administered drug that is metabolized by the same enzyme
path?
A. Increased plasma levels of the co-administered drug
B. Immediate toxicity of the co-administered drug
C. No change in the metabolism of the co-administered drug
D. Decreased plasma levels of the co-administered drug
Answer: D
Rationale: Enzyme inducers increase the rate of drug metabolism, which typically leads to decreased
plasma levels and reduced therapeutic effect of the substrate drug. Remembering this point will help
you decide the best nursing action when similar questions appear on the exam. Link the answer to the
client’s current condition and risk level. Remembering this point will help you decide the best nursing

2. Which of the following is the most appropriate initial treatment for a patient newly
diagnosed with Type 2 Diabetes Mellitus and an A1C of 7.5%, assuming no
contraindications?
A. Metformin
B. Glyburide
C. Insulin Glargine
D. Sitagliptin
Answer: A
Rationale: Metformin is the first-line gold standard for Type 2 Diabetes due to its efficacy, safety, and
weight-neutral effects. Understanding this helps the nurse notice early warning signs and act before
the problem gets worse. Early action often prevents bigger complications for the client. Knowing the
reason behind the correct answer makes it easier to rule out the wrong options quickly. Look for the
choice that protects the client and matches the priority need.

3. What is the primary mechanism of action of Albuterol (ProAir) in the treatment of asthma?
A. Antagonism of muscarinic receptors
B. Selective beta-2 adrenergic receptor agonism
C. Inhibition of leukotriene synthesis
D. Reduction of airway inflammation through corticosteroid binding
Answer: B
Rationale: Albuterol is a Short-Acting Beta Agonist (SABA) that stimulates beta-2 receptors in the
lungs, causing bronchodilation. Remembering this point will help you decide the best nursing action
when similar questions appear on the exam. Link the answer to the client’s current condition and risk
level. Exam questions often test whether you can pick the most practical and safe choice for the client
in real situations. Focus on what the nurse can actually do right now.
4. A 65-year-old male with a history of heart failure (HFrEF) requires treatment for
hypertension. Which class of medication is contraindicated for this patient?
A. ACE Inhibitors
B. Beta Blockers
C. Non-dihydropyridine Calcium Channel Blockers (e.g., Verapamil)
D. Loop Diuretics
Answer: C
Rationale: Non-dihydropyridine CCBs like Verapamil and Diltiazem have negative inotropic effects
and can worsen heart failure. Understanding this helps the nurse notice early warning signs and act
before the problem gets worse. Early action often prevents bigger complications for the client.
Remembering this point will help you decide the best nursing action when similar questions appear on
the exam. Link the answer to the client’s current condition and risk level.
