CARE OF THE FUNDAMENTALS EXAM
QUESTIONS AND VERIFIED ANSWERS
(2026/ 2027 UPDATE)- CHAMBERLAIN
1. When considering the volume of distribution (Vd) of a drug, which of the following
statements is correct regarding a drug with a high Vd?
A. The drug is likely lipophilic and distributes widely into tissues.
B. The drug is likely highly protein-bound in the plasma.
C. The drug is primarily confined to the intravascular space.
D. The drug will be cleared more rapidly by the kidneys.
Answer: A
Conceptual Explanation: A high volume of distribution indicates that the drug has left the
plasma and distributed extensively into the extravascular tissues, which is common for
lipophilic drugs.
2. According to the Controlled Substances Act, which schedule of drugs has a high potential
for abuse but has currently accepted medical use in the United States?
A. Schedule I
B. Schedule III
,C. Schedule II
D. Schedule IV
Answer: C
Conceptual Explanation: Schedule II drugs have a high potential for abuse and may lead
to severe psychological or physical dependence, but they have accepted medical uses,
unlike Schedule I drugs.
3. In an elderly patient with decreased serum albumin levels, what is the primary concern
when prescribing a highly protein-bound medication?
A. Increased excretion rate by the kidneys.
B. Decreased therapeutic effect due to rapid metabolism.
C. Reduced absorption in the gastrointestinal tract.
D. Increased risk of drug toxicity due to higher free drug levels.
Answer: D
Conceptual Explanation: Low albumin means fewer binding sites, leading to an increase
in the free (active) fraction of highly protein-bound drugs, which increases the risk of
toxicity.
4. Which phase of clinical trials primarily focuses on determining the safety and dosage range
of a new drug in a small group of healthy volunteers?
A. Phase IV
, B. Phase II
C. Phase III
D. Phase I
Answer: D
Conceptual Explanation: Phase I trials are conducted on a small number of healthy
volunteers to assess safety, metabolism, and pharmacokinetics.
5. A patient is taking a drug that is a known substrate of the CYP3A4 enzyme. If they begin
taking a second drug that is a potent CYP3A4 inducer, what is the most likely outcome?
A. The plasma concentration of the substrate drug will increase.
B. The substrate drug will become toxic.
C. The half-life of the substrate drug will increase.
D. The plasma concentration of the substrate drug will decrease.
Answer: D
Conceptual Explanation: Inducers increase the activity of enzymes, leading to faster
metabolism and lower plasma concentrations of substrate drugs.
6. What is the primary reason why serum creatinine may not be an accurate reflection of
renal function in a frail, elderly patient?
A. Elderly patients produce more creatinine due to age.
B. Reduced muscle mass leads to lower creatinine production.
