VERSION 2026/2027 (PASS GUARANTEE)
Q: What is the primary purpose of the Phase 1 clinical trial?
ANSWER To assess safety and dosage in a small group of healthy
volunteers.
Q: Define pharmacokinetics.
ANSWER The study of how the body moves a drug through the system
(Absorption, Distribution, Metabolism, Excretion).
Q: Define pharmacodynamics.
ANSWER The study of what the drug does to the body (mechanism of
action).
Q: What is the first-pass effect?
ANSWER The metabolism of a drug by the liver before it reaches
systemic circulation.
Q: Which route of administration bypasses the first-pass effect?
ANSWER Intravenous (IV), Sublingual, and Transdermal.
Q: What is bioavailability?
ANSWER The percentage of the administered drug dose that reaches
systemic circulation.
Q: A patient has renal failure. How will this affect drug excretion?
ANSWER It will decrease excretion, leading to a risk of drug toxicity.
Q: What is the therapeutic index?
ANSWER A ratio comparing the toxic dose to the effective dose; a low
index means the drug has a narrow safety margin.
Q: What is the onset of action?
, ANSWER The time it takes for the drug to reach the minimum effective
concentration after administration.
Q: What is the peak action?
ANSWER The time when the drug reaches its highest concentration in the
blood.
Q: What is the duration of action?
ANSWER The length of time the drug has a pharmacological effect.
Q: What is the half-life of a drug?
ANSWER The time it takes for half of the drug concentration to be
eliminated from the body.
Q: What are the "Five Rights" of medication administration?
ANSWER Right Patient, Right Drug, Right Dose, Right Route, Right Time.
Q: What is agonism?
ANSWER A drug that binds to a receptor and stimulates a response.
Q: What is antagonism?
ANSWER A drug that binds to a receptor and blocks or inhibits a
response.
Q: What is the Black Box Warning?
ANSWER The strictest warning issued by the FDA regarding serious or
life-threatening adverse effects.
Q: What does PRN mean?
ANSWER "Pro re nata" – as needed.
Q: What is a placebo effect?
ANSWER A psychological response to an inactive substance.
Q: What is idiosyncrasy?
ANSWER An unexpected, individual hypersensitivity to a drug (genetic
basis).
Q: What is tolerance?
, ANSWER A decreased response to a drug over time, requiring a higher
dose to achieve the same effect.
Part 2: Pain & Inflammation (21-40)
Q: What is the mechanism of action (MOA) for NSAIDs (e.g., Ibuprofen,
Naproxen)?
ANSWER Inhibition of cyclooxygenase (COX) enzymes, reducing
prostaglandin synthesis.
Q: What is a major adverse effect of NSAIDs?
ANSWER GI irritation/ulcers, bleeding, and kidney damage.
Q: Why are COX-2 inhibitors (Celecoxib) prescribed?
ANSWER To reduce pain/inflammation with lower risk of GI ulcers
compared to non-selective NSAIDs.
Q: What is the MOA of Acetaminophen (Tylenol)?
ANSWER Inhibits prostaglandin synthesis in the CNS (exact mechanism
unknown); has little anti-inflammatory effect.
Q: What is the toxic dose of Acetaminophen for an adult, generally?
ANSWER >4g/day (sometimes lower in chronic alcoholics or those with
liver disease).
Q: What is the antidote for Acetaminophen toxicity?
ANSWER Acetylcysteine (Mucomyst).
Q: What is the primary side effect of Opioids?
ANSWER Respiratory depression.
Q: What is the antidote for Opioid overdose?
ANSWER Naloxone (Narcan).
Q: What is a common side effect of Opioids that requires nursing
intervention?
ANSWER Constipation (stool softeners are often prophylactically
ordered).
Q: What is the ceiling effect for Aspirin?
