Question | Chamberlain
1. Which phase of pharmacokinetics is primarily affected by a patient’s liver function?
A. Metabolism
B. Distribution
C. Absorption
D. Excretion
Correct Answer: A
Expert Explanation: Metabolism occurs primarily in the liver through enzyme
systems like the Cytochrome P450. Liver impairment can significantly reduce the
rate at which drugs are biotransformed. This often leads to increased drug levels
and a higher risk of toxicity in patients with hepatic disease.
2. A drug with a high first-pass effect should ideally be administered through which
route to ensure maximum bioavailability?
A. Oral
B. Intravenous
C. Sublingual
,D. Rectal
Correct Answer: B
Expert Explanation: The first-pass effect refers to the metabolism of a drug in the
liver before it reaches systemic circulation. Intravenous administration bypasses the
gastrointestinal tract and the liver entirely upon entry. This ensures that 100% of
the drug dose reaches the systemic circulation immediately.
3. According to the Controlled Substances Act, which schedule of drugs has the highest
potential for abuse while still having a currently accepted medical use?
A. Schedule I
B. Schedule II
C. Schedule III
D. Schedule IV
Correct Answer: B
Expert Explanation: Schedule II drugs have a high potential for abuse which may
lead to severe psychological or physical dependence. Unlike Schedule I drugs, they
have a currently accepted medical use in treatment in the United States. Examples
include morphine, oxycodone, and methylphenidate.
, 4. What is the primary goal of the ‘Beers Criteria’ in geriatric pharmacology?
A. To list medications that are potentially inappropriate for older adults.
B. To identify drugs that are most effective for hypertension in the elderly.
C. To determine the correct pediatric dosing based on weight.
D. To categorize drugs based on their pregnancy safety profiles.
Correct Answer: A
Expert Explanation: The Beers Criteria provides a list of medications that should
generally be avoided or used with caution in older adults. These medications are
associated with a higher risk of adverse drug reactions in the geriatric population.
Following these guidelines helps improve the safety and quality of care for elderly
patients.
5. Which term describes the amount of drug that reaches the systemic circulation in
an unchanged form?
A. Clearance
B. Half-life
C. Volume of distribution
D. Bioavailability
Correct Answer: D
