- The binding affinity of a drug to plasma proteins
Correct answer: The ratio of ionized to un-ionized drug at a given pH
The Henderson-Hasselbalch equation (pH = pKa + log[A⁻]/[HA]) predicts the ionization state of a weak acid or base at a given pH, which determines membrane permeability and absorption.
Question 2: Which statistical measure describes the ratio of risk in the treatment group compared to the control group?
- Absolute risk reduction (ARR)
- Relative risk (RR) (Correct answer)
- Confidence interval (CI)
- Number needed to harm (NNH)
Correct answer: Relative risk (RR)
Relative risk (RR) is the ratio of the probability of an outcome in the treatment group to the probability in the control group.
Question 3: A patient develops methemoglobinemia after topical benzocaine use. Which finding confirms the diagnosis?
- PaO2 of 45 mmHg on ABG with normal pulse oximetry
- Pulse oximetry reading of 85% with SpO2 saturation gap on ABG

Correct answer: Attrition bias
Attrition bias (also called dropout bias) occurs when loss to follow-up is related to the outcome, distorting results.
Question 47: The renal clearance of a drug is found to be greater than GFR (125 mL/min). This indicates which renal mechanism?
- Protein-bound fraction being filtered
- Glomerular filtration only
- Net tubular reabsorption
- Net tubular secretion (Correct answer)
Correct answer: Net tubular secretion
Renal clearance exceeding GFR means additional drug is being added to tubular fluid via active secretion beyond what filtration alone can account for.
Question 48: Which cardiac glycoside toxicity symptom is MOST directly caused by inhibition of the Na+/K+-ATPase pump?
- Ventricular arrhythmias due to increased intracellular calcium (Correct answer)
- Visual disturbances such as yellow-green halos
- Bradycardia mediated by increased vagal tone
- Nausea and vomiting via central chemoreceptor trigger zone stimulation
Correct answer: Ventricular arrhythmias due to increased intracellular calcium
Na+/K+-ATPase inhibition increases intracellular Na+, reducing Na+/Ca²+ exchanger activity, leading to intracellular Ca²+ overload that triggers delayed afterdepolarizations and ventricular arrhythmias.
Question 49: Therapeutic drug monitoring (TDM) is MOST useful for drugs with which characteristics?
- High bioavailability and no protein binding
- Narrow therapeutic index and high interpatient pharmacokinetic variability (Correct answer)
- Short half-life and complete renal elimination

- There is a 95% probability the null hypothesis is false
- The true difference is exactly 5.25 mmHg
- The p-value is 0.95
- We are 95% confident the true difference lies between 2.1 and 8.4 mmHg (Correct answer)
Correct answer: We are 95% confident the true difference lies between 2.1 and 8.4 mmHg
A 95% CI means that 95% of such intervals constructed from repeated sampling would contain the true population parameter.
Question 57: A drug's bioavailability is 30% by oral route. To achieve the same AUC as a 50 mg IV dose, the oral dose should be:
- 50 mg
- 500 mg
- 167 mg (Correct answer)
- 15 mg
Correct answer: 167 mg
Oral dose = IV dose / F = 50 mg / 0.30 ≈ 167 mg to compensate for the 70% lost to incomplete absorption and first-pass.
Question 58: Under HIPAA, which of the following is a permissible disclosure of protected health information (PHI) WITHOUT patient authorization?
- Reporting a communicable disease to the state health department (Correct answer)
- Sharing prescription history with an employer for insurance purposes

Question 132: A child ingests iron tablets. During the latent phase (6-24 hours post-ingestion), the patient appears to improve. What dangerous misconception can this create?
- The false sense of recovery may delay needed treatment before systemic toxicity begins (Correct answer)
- The ingested iron has been fully absorbed
- The iron has been converted to non-toxic ferritin
- Hepatic failure has already resolved
Correct answer: The false sense of recovery may delay needed treatment before systemic toxicity begins
The latent phase of iron poisoning creates a deceptive improvement after initial GI symptoms, but systemic toxicity, hepatic failure, and circulatory collapse may follow without treatment.
Question 133: Which drug is used to reverse the effects of benzodiazepine overdose?
- Physostigmine
- N-acetylcysteine
- Naloxone
- Flumazenil (Correct answer)
Correct answer: Flumazenil
