QUESTION 1
What term describes the study of how medications are absorbed,
distributed, metabolized, and excreted by the body?
• A. Pharmacodynamics
• B. Pharmacokinetics
• C. Toxicology
• D. Pharmacotherapeutics
Correct Answer: B. Pharmacokinetics
Detailed Rationale: Pharmacokinetics refers to what the body does to a
medication (absorption, distribution, metabolism, and excretion -
ADME). In contrast, pharmacodynamics describes what the drug does
to the body (its mechanism of action and physiological effects).
QUESTION 2
Which route of administration bypasses the first-pass hepatic
metabolism entirely, allowing for rapid systemic absorption?
• A. Oral (PO)
• B. Sublingual (SL)
• C. Rectal (PR)
, • D. Enteral tube
Correct Answer: B. Sublingual (SL)
Detailed Rationale: Medications administered sublingually or buccally
are absorbed directly into the systemic venous circulation via the rich
mucosal blood supply under the tongue, completely bypassing the
portal system and the liver's first-pass metabolism.
QUESTION 3
What is the primary mechanism of action of epinephrine when
administered during cardiac arrest?
• A. Direct parasympathetic stimulation causing negative
chronotropy
• B. Alpha-1 receptor-mediated peripheral vasoconstriction, which
enhances coronary and cerebral perfusion pressure
• C. Selective beta-2 bronchodilation to clear airway secretions
• D. Direct suppression of ventricular ectopy
Correct Answer: B. Alpha-1 receptor-mediated peripheral
vasoconstriction, which enhances coronary and cerebral perfusion
pressure
Detailed Rationale: Epinephrine acts as a potent non-selective
adrenergic agonist. Its alpha-1 mediated vasoconstriction significantly
increases systemic vascular resistance, thereby raising diastolic blood
pressure and improving coronary and cerebral perfusion pressures
during CPR.
QUESTION 4
,Why must adenosine be administered via a rapid IV push followed by a
saline flush, typically through an antecubital site closest to the heart?
• A. It causes immediate local skin necrosis if given in peripheral
veins.
• B. It has an extremely short biological half-life of approximately 10
seconds.
• C. It binds instantly to plastic tubing and precipitates out of
solution.
• D. It requires high fluid pressures to dissolve active crystals.
Correct Answer: B. It has an extremely short biological half-life of
approximately 10 seconds.
Detailed Rationale: Adenosine is rapidly cleared from the bloodstream
by cellular uptake and deamination, resulting in a half-life of less than
10 seconds. Rapid IV push and a flush ensure the drug reaches the heart
before it is metabolized.
QUESTION 5
Classified as a Vaughan-Williams Class III antiarrhythmic, what is the
primary cellular action of amiodarone?
• A. Fast sodium channel blockade
• B. Calcium channel blockade exclusively at the AV node
• C. Potassium channel blockade, prolonging repolarization and the
refractory period
• D. Beta-adrenergic receptor stimulation
, Correct Answer: C. Potassium channel blockade, prolonging
repolarization and the refractory period
Detailed Rationale: Amiodarone primarily blocks potassium channels,
which delays repolarization, widens the action potential duration, and
prolongs the refractory period in cardiac tissues, making it effective for
both supraventricular and ventricular arrhythmias.
QUESTION 6
What is the pharmacological classification of naloxone?
• A. Full opioid agonist
• B. Competitive opioid receptor antagonist
• C. Partial opioid agonist-antagonist
• D. Non-opioid central nervous system depressant
Correct Answer: B. Competitive opioid receptor antagonist
Detailed Rationale: Naloxone has a high affinity for opioid receptors
(mu, kappa, delta) where it competitively binds without activating
them, rapidly displacing opioid molecules and reversing respiratory
depression and central nervous system sedation.
QUESTION 7
Which patient condition represents an absolute contraindication to the
administration of sublingual nitroglycerin?
• A. History of chronic hypertension
• B. Recent use of phosphodiesterase-5 (PDE-5) inhibitors within the
past 24–48 hours
