Pharmacology: PK/PD High-Yield Concepts for FNP
Exam Newest 2026 Questions and Correct Detailed
Answers Already Graded A+
What is the significance of renal impairment in drug dosing? - CORRECT
ANSWER-It often requires dose reduction or longer dosing intervals due to
altered drug clearance.
What is a loading dose? - CORRECT ANSWER-A higher initial dose of a drug
used to quickly achieve therapeutic levels.
What pharmacokinetic changes occur in older adults? - CORRECT ANSWER-
Reduced renal function, hepatic metabolism, and altered body composition
increase the risk of drug accumulation and adverse effects.
How does drug metabolism differ in pediatrics? - CORRECT ANSWER-Neonates
and infants have immature liver and kidney function, leading to slower or
unpredictable drug metabolism and elimination.
What is passive diffusion in drug absorption? - CORRECT ANSWER-The most
common mechanism, moving drugs from high concentration to low concentration
without energy.
, What does pharmacokinetics (PK) refer to? - CORRECT ANSWER-What the
body does to the drug, including absorption, distribution, metabolism, and
excretion (ADME).
What does pharmacodynamics (PD) refer to? - CORRECT ANSWER-What the
drug does to the body, including receptor binding, potency, efficacy, and dose-
response.
What is bioavailability? - CORRECT ANSWER-The fraction of administered drug
that reaches systemic circulation; IV = 100%, oral often reduced by first-pass
metabolism.
What is half-life in pharmacology? - CORRECT ANSWER-The time for plasma
concentration of a drug to fall by 50%; steady state usually takes about 4-5 half-
lives.
What is absorption in pharmacokinetics? - CORRECT ANSWER-The movement
of drug from the site of administration into the bloodstream.
What factors influence drug absorption? - CORRECT ANSWER-pH and
ionization, food effects, blood flow to the GI tract, and drug formulation.
