prepare for pharmacology midterm exams
1. Pharmacokinetics and Pharmacodynamics
Question 1
A nurse practitioner explains that the liver transforms medications into more water-soluble
compounds to facilitate excretion. This process is known as:
A. Distribution
B. Absorption
C. Metabolism
D. Elimination
Correct Answer: C. Metabolism
Rationale: Metabolism primarily occurs in the liver and converts drugs into more water-
soluble forms for renal or biliary excretion.
,Question 2
Which factor most significantly affects oral drug absorption?
A. Plasma protein binding
B. Gastric pH and gastric emptying
C. Renal blood flow
D. Drug half-life
Correct Answer: B. Gastric pH and gastric emptying
Rationale: Oral medications are affected by gastrointestinal factors such as pH, food
intake, and gastric motility.
Question 3
A medication with a narrow therapeutic index requires careful monitoring because:
A. It is rapidly absorbed
B. Toxicity can occur with small dosage changes
C. It has a long half-life
D. It is poorly distributed
Correct Answer: B. Toxicity can occur with small dosage changes
Rationale: Narrow therapeutic index drugs have a small margin between therapeutic and
toxic doses.
Question 4
The time required for half of a drug concentration to be eliminated from the body is called:
A. Peak level
B. Bioavailability
C. Half-life
D. Potency
Correct Answer: C. Half-life
Rationale: Half-life determines dosing intervals and duration of action.
,Question 5
A highly protein-bound medication may cause toxicity when administered with another
protein-bound drug because:
A. Both drugs become inactive
B. Drug metabolism decreases
C. One drug displaces the other, increasing free drug levels
D. Renal excretion stops completely
Correct Answer: C. One drug displaces the other, increasing free drug levels
Rationale: Displacement from albumin increases active free drug concentration.
2. Safe Prescribing and Adverse Drug Reactions
Question 6
Which patient is at greatest risk for adverse drug reactions?
A. Healthy adolescent
B. Middle-aged athlete
C. Older adult taking multiple medications
D. Young adult with seasonal allergies
Correct Answer: C. Older adult taking multiple medications
Rationale: Polypharmacy and age-related physiologic changes increase adverse drug
reaction risk.
Question 7
An idiosyncratic drug reaction is best described as:
A. A predictable dose-related effect
B. A therapeutic effect
C. An unusual, unpredictable reaction
D. A placebo response
Correct Answer: C. An unusual, unpredictable reaction
Rationale: Idiosyncratic reactions are abnormal and not related to normal pharmacologic
mechanisms.
, Question 8
Which statement about black box warnings is correct?
A. They identify medications with minimal side effects
B. They indicate severe or life-threatening risks
C. They are optional prescribing guidelines
D. They only apply to controlled substances
Correct Answer: B. They indicate severe or life-threatening risks
Rationale: Black box warnings are the FDA’s strongest medication safety warnings.
Question 9
A patient develops hives and wheezing immediately after taking penicillin. This reaction is
classified as:
A. Side effect
B. Drug tolerance
C. Allergic hypersensitivity reaction
D. Therapeutic duplication
Correct Answer: C. Allergic hypersensitivity reaction
Rationale: Hives and wheezing suggest an IgE-mediated allergic reaction.
Question 10
Which strategy helps reduce medication errors?
A. Using abbreviations freely
B. Prescribing verbal orders whenever possible
C. Medication reconciliation at every transition of care
D. Avoiding patient education
Correct Answer: C. Medication reconciliation at every transition of care
Rationale: Medication reconciliation identifies omissions, duplications, and interactions.
