Questions 1–8 → Pharmacokinetics & Medication Principles
Q1. A practical nurse administers an oral medication to a client with delayed gastric
emptying and asks the client to remain upright afterward. Which principle best
explains why the onset of action may still be delayed?
A. Increased protein binding
B. Reduced first-pass metabolism
C. Delayed gastrointestinal absorption
D. Increased renal excretion
Correct Answer: 🔴 C. Delayed gastrointestinal absorption
Explanation: 🔹 Oral medications must first dissolve and be absorbed before
entering systemic circulation. Delayed gastric emptying prolongs movement into
the small intestine, where most absorption occurs. Protein binding and renal
excretion occur after absorption. Reduced first-pass metabolism would not explain
delayed onset.
Q2. A nurse reviews a medication order for a client receiving two highly protein-
bound drugs. Which finding should prompt increased monitoring?
A. Elevated free-drug concentration
B. Increased drug elimination
C. Reduced tissue exposure
D. Reduced adverse effect risk
Correct Answer: 🔴 A. Elevated free-drug concentration
Explanation: 🔹 Highly protein-bound medications can compete for albumin sites,
increasing circulating active drug and toxicity risk. Elimination does not necessarily
increase. More free drug generally increases tissue exposure and adverse reactions.
,Q3. A client with chronic kidney disease receives a renally eliminated medication.
What action reflects sound pharmacologic judgment?
A. Administer additional doses
B. Evaluate need for dosage adjustment
C. Increase administration frequency
D. Skip monitoring laboratory results
Correct Answer: 🔴 B. Evaluate need for dosage adjustment
Explanation: 🔹 Impaired renal function decreases drug clearance and may cause
accumulation. Dose or interval adjustment is often required. Increasing doses or
avoiding monitoring increases toxicity risk.
Q4. Which factor most directly affects drug bioavailability?
A. Hair color
B. Route of administration
C. Occupation
D. Hand dominance
Correct Answer: 🔴 B. Route of administration
Explanation: 🔹 Bioavailability refers to how much active drug reaches circulation.
Intravenous administration provides complete bioavailability, while oral
medications undergo absorption and first-pass effects. The remaining options are
unrelated.
Q5. A nurse teaches a client prescribed a sustained-release medication. Which
statement indicates understanding?
A. “I can crush this medication if swallowing is difficult.”
B. “Breaking the tablet improves absorption.”
, C. “I should swallow the medication intact.”
D. “I should dissolve the tablet before use.”
Correct Answer: 🔴 C. “I should swallow the medication intact.”
Explanation: 🔹 Sustained-release formulations are designed to release medication
gradually. Crushing or dissolving can cause dose dumping and toxicity.
Q6. A medication has a narrow therapeutic index. Which nursing action is highest
priority?
A. Encourage herbal use
B. Administer at flexible times
C. Monitor therapeutic and toxic responses carefully
D. Avoid documenting outcomes
Correct Answer: 🔴 C. Monitor therapeutic and toxic responses carefully
Explanation: 🔹 Narrow therapeutic index drugs have limited separation between
effective and toxic doses. Careful assessment and monitoring reduce harm.
Q7. A nurse administers an intramuscular medication. Which factor most increases
absorption speed?
A. Reduced tissue perfusion
B. Enhanced blood flow at injection site
C. Increased adipose thickness
D. Cold compress immediately after administration
Correct Answer: 🔴 B. Enhanced blood flow at injection site
Explanation: 🔹 Drug absorption increases with greater perfusion. Poor circulation
and excessive adipose tissue slow absorption.
