,Section 1: Pharmacological Principles & Medication Safety (Questions
1–15)
Q1: Which pharmacokinetic process describes movement of a drug from the bloodstream
into tissues?
A. Absorption
B. Distribution [CORRECT]
C. Metabolism
D. Excretion
Correct Answer: B
Rationale: Distribution is movement from circulation into tissues and body compartments.
Absorption is entry into blood, metabolism is chemical alteration, and excretion removes drug or
metabolites.
Q2: A patient with severe chronic kidney disease is prescribed a renally cleared
medication. Which pharmacokinetic change is most likely?
A. Reduced drug clearance and prolonged half-life [CORRECT]
B. Increased first-pass metabolism
C. Faster renal elimination
D. Reduced drug distribution in every case
Correct Answer: A
Rationale: Impaired renal function can decrease clearance and cause accumulation, so dose or
interval may need adjustment. It does not inherently increase first-pass metabolism or renal
elimination.
Q3: A medication has a narrow therapeutic index. What is the priority nursing
implication?
A. Monitor for therapeutic response and toxicity, including ordered drug levels [CORRECT]
B. Assume standard doses are safe for every patient
C. Give extra doses if the first dose has no immediate effect
D. Avoid documenting administration times
Correct Answer: A
Rationale: Small differences between therapeutic and toxic concentrations require careful
monitoring and accurate dosing. Blind dose escalation or poor documentation increases risk.

, Q4: A patient asks why a loading dose is prescribed. Which explanation is correct?
A. It rapidly achieves a target concentration when prompt therapeutic levels are needed
[CORRECT]
B. It prevents all adverse effects
C. It replaces every maintenance dose
D. It slows absorption to zero
Correct Answer: A
Rationale: A loading dose is designed to reach the target concentration more quickly, often for
drugs with long half-lives. Maintenance doses then sustain the concentration.
Q5: A patient develops hives and wheezing minutes after an antibiotic dose. What is the
nurse's priority?
A. Stop the medication, initiate emergency response, and support airway/breathing per protocol
[CORRECT]
B. Document the reaction and give the next dose more slowly
C. Ask the patient to walk to assess symptoms
D. Wait for the prescriber to round
Correct Answer: A
Rationale: Hives with wheezing may indicate anaphylaxis and require immediate medication
cessation and emergency treatment. Continuing or delaying response is unsafe.
Q6: Which action best reduces wrong-patient medication errors?
A. Use two approved patient identifiers and compare them with the medication record
[CORRECT]
B. Identify the patient by room number
C. Ask a nearby visitor to confirm the patient's name
D. Prepare medications for several patients together without labels
Correct Answer: A
Rationale: Two patient identifiers matched to the order help prevent wrong-patient administration.
Room number and bystander confirmation are not reliable identifiers.
