,1. Which of the following best describes the mechanism of action
of ACE inhibitors?
a) They block calcium channels.
b) They inhibit the angiotensin-converting enzyme, decreasing
angiotensin II production.
c) They promote nitric oxide synthesis.
d) They act on beta-adrenergic receptors.
Answer: b
Rationale: ACE inhibitors prevent the conversion of
angiotensin I to angiotensin II, leading to vasodilation and reduced
blood pressure.
2. Which class of antibiotics has a mechanism of action that
involves the inhibition of bacterial protein synthesis?
a) Cephalosporins
b) Macrolides
c) Penicillins
d) Quinolones
Answer: b
© 2024/2025
, Rationale: Macrolides inhibit bacterial protein synthesis by
binding to the 50S ribosomal subunit.
3. A nurse is administering a medication that increases the risk of
serotonin syndrome. Which of the following medications should
be monitored closely?
a) Prednisone
b) Paroxetine
c) Hydrocodone
d) Atorvastatin
Answer: b
Rationale: Paroxetine is a selective serotonin reuptake
inhibitor (SSRI), and combining it with other serotonergic drugs
can increase serotonin levels to dangerous levels.
4. Which type of drug is primarily used to manage acute asthma
exacerbations?
a) Long-acting beta agonists (LABAs)
b) Corticosteroids
c) Short-acting beta agonists (SABAs)
d) Anticholinergics
Answer: c
