Building Your Foundation: Pharmacology Basics & Safe Medication
Administration
Q1: A patient is prescribed a medication that undergoes extensive first-pass
metabolism in the liver. Which route would have the highest bioavailability for this drug?
A. Oral administration
B. Intravenous injection [CORRECT]
C. Subcutaneous injection
D. Transdermal patch
Correct Answer: B
Rationale: Intravenous administration bypasses the first-pass effect entirely, delivering
100% bioavailability. Oral drugs absorbed from the GI tract enter the portal circulation
and undergo hepatic metabolism before reaching systemic circulation, significantly
reducing bioavailability for drugs with high first-pass extraction. Other routes avoid
first-pass to varying degrees but IV is complete.
Q2: You're caring for a patient with liver cirrhosis. Which pharmacokinetic phase is most
significantly affected?
A. Absorption
B. Metabolism [CORRECT]
C. Distribution
D. Excretion
Correct Answer: B
,Rationale: The liver is the primary site of drug metabolism via the cytochrome P450
enzyme system. Cirrhosis reduces metabolic capacity, leading to drug accumulation
and increased toxicity risk. While protein binding (distribution) may be affected due to
decreased albumin, metabolism is the most significantly impaired phase.
Q3: A medication order reads: "Give 0.125 mg digoxin PO daily." This is an example of
which type of order?
A. PRN order
B. Standing order [CORRECT]
C. STAT order
D. One-time order
Correct Answer: B
Rationale: A standing order is carried out until discontinued or for a specified period.
"Daily" indicates ongoing administration. PRN means as needed, STAT means
immediately, and one-time is single dose. Understanding order types prevents timing
errors.
Q4: You're administering medications to a pediatric patient. The dosage calculation
uses Clark's Rule based on weight. This is necessary because:
A. Children are just small adults
B. Pediatric patients have different body composition, organ maturity, and
pharmacokinetic profiles [CORRECT]
C. Adult doses are always too small
D. Weight-based calculations are easier
Correct Answer: B
Rationale: Children aren't miniature adults—they have higher body water content, less
fat, immature liver/kidney function, and different receptor sensitivity. Weight-based or
body surface area calculations account for these differences. Adult doses can be
dangerous (often too high), and calculations require precision, not convenience.
Q5: A patient is taking warfarin and starts St. John's Wort for depression. What's the
primary concern?
,A. Increased risk of bleeding due to potentiation
B. Decreased warfarin effectiveness due to CYP450 induction, increasing clot risk
[CORRECT]
C. No interaction between herbal supplements and anticoagulants
D. Enhanced antidepressant effect
Correct Answer: B
Rationale: St. John's Wort induces CYP450 enzymes (3A4, 2C9), increasing warfarin
metabolism and reducing anticoagulant effect, potentially causing therapeutic failure
and thrombosis. Many patients assume "natural" means safe—nurses must educate
about herb-drug interactions and monitor INR closely.
Q6: The "Rights of Medication Administration" include all EXCEPT:
A. Right patient, right drug, right dose, right route, right time
B. Right reason, right documentation, right response, right to refuse
C. Right technique, right education, right assessment
D. Right cost, right convenience [CORRECT]
Correct Answer: D
Rationale: The 10 rights include patient, drug, dose, route, time, reason, documentation,
response, technique, and education/assessment. Cost and convenience are never
factors in safe medication administration—therapeutic appropriateness and patient
safety are paramount.
Q7: A patient has a serum albumin level of 2.8 g/dL (normal 3.5-5.0). Which drug effect
would you anticipate?
A. Increased free (active) drug for highly protein-bound medications [CORRECT]
B. Decreased drug effectiveness for all medications
C. No change in drug pharmacodynamics
D. Increased drug binding
Correct Answer: A
Rationale: Hypoalbuminemia reduces binding sites for protein-bound drugs (warfarin,
phenytoin, diazepam), increasing the free (unbound, pharmacologically active) fraction.
, This increases effect and toxicity risk even with "normal" total drug levels. Monitoring
free levels or clinical signs is essential.
Q8: You're teaching a patient about sublingual nitroglycerin. The correct administration
technique is:
A. Swallow immediately with water
B. Place under tongue, allow to dissolve without swallowing, repeat every 5 minutes × 3
if needed [CORRECT]
C. Chew thoroughly before swallowing
D. Take with food to prevent stomach upset
Correct Answer: B
Rationale: Sublingual administration avoids first-pass metabolism—drug dissolves
under tongue and enters systemic circulation via sublingual veins. Swallowing, chewing,
or food delays absorption and reduces effectiveness. The "5 minutes × 3" protocol is
standard for angina—if pain persists after 3 doses, call 911.
Q9: A medication error occurs when a nurse administers the wrong dose. The first
priority is:
A. Complete the incident report immediately
B. Assess the patient for adverse effects and notify the prescriber [CORRECT]
C. Hide the error to avoid disciplinary action
D. Administer the correct dose immediately without assessment
Correct Answer: B
Rationale: Patient safety is always first—assess for toxicity or therapeutic failure,
implement emergency measures if needed, and notify prescriber for orders. Incident
reports (quality improvement) come after patient stabilization. Concealment is
unethical and illegal. Additional drug without assessment compounds the error.
Q10: A patient asks about taking ibuprofen with their prescribed aspirin for heart
protection. Your response is:
A. It's fine to take them together
B. Ibuprofen can interfere with aspirin's antiplatelet effect—separate dosing or consider
acetaminophen [CORRECT]
