Master Pharmacology Essentials for 2026 Victory
Pharmacology is often considered the toughest subject in nursing exams due to the vast classification of drugs. In today's Pharmacology Mock Test, we have simplified General Pharmacology concepts for you. This quiz covers high-yield MCQs on Autonomic Nervous System (ANS) drugs, including Anticholinergics, along with Gastrointestinal (GIT) agents and Antimicrobial drugs.
Understanding the mechanism of action, side effects, and nursing responsibilities for these drug classes is crucial for AIIMS NORCET, ESIC, and NCLEX-RN aspirants. Practice these solved questions with rationales to master medical management. Download your free PDF below and build the strong pharmacology base needed for top scores!

Why These Pharmacology Topics Are Your Score Multipliers
Pharmacology remains a dominant section across nursing officer recruitment exams:
- Drug mechanisms and adverse effects test critical thinking
- ANS drugs and antimicrobials appear in high-frequency scenarios
- GIT agents and anticholinergics evaluate therapeutic application
- Understanding rationale behind choices separates top rankers

Essential Concepts You Must Master for Top Ranks
General Pharmacology
Quick Fact
Pharmacokinetics describes what the body does to the drug.
Complete Coverage
Core Principles
- Pharmacodynamics: drug effects on body (receptor interaction)
- Pharmacokinetics: absorption, distribution, metabolism, excretion (ADME)
Key Terms
- Bioavailability: fraction reaching systemic circulation
- Half-life: time for 50 % reduction
- First-pass effect: hepatic metabolism before circulation
Routes Comparison
IV: 100 % bioavailability, rapid onset
Oral: convenient, first-pass effect
High-yield fact for exams
Volume of distribution high in lipophilic drugs.
Autonomic Nervous System Drugs
Quick Fact
Sympathetic = fight or flight, parasympathetic = rest and digest.
Complete Coverage
Receptor Summary
| System | Neurotransmitter | Receptors | Effects |
|---|---|---|---|
| Sympathetic | Norepinephrine | Alpha 1 (vasoconstriction), Beta 1 (heart), Beta 2 (bronchodilation) | Increased HR, BP, bronchodilation |
| Parasympathetic | Acetylcholine | Muscarinic (M1–M5) | Decreased HR, increased secretions |
Adrenergic Drugs
Alpha agonists (phenylephrine – vasoconstriction)
Beta agonists (salbutamol – bronchodilation)
Cholinergic Drugs
Direct (pilocarpine), indirect (neostigmine)
High-yield fact for exams
Beta 2 selective = salbutamol for asthma.
Anticholinergics
Quick Fact
Atropine is prototype anticholinergic.
Complete Coverage
Mechanism
Block muscarinic receptors → parasympathetic inhibition
Effects
Dry mouth, blurred vision, tachycardia, constipation, urinary retention
Uses
Pre-anesthetic (reduce secretions), bradycardia, organophosphate poisoning
Toxicity Mnemonic
"Hot as hare, blind as bat, dry as bone, red as beet, mad as hatter"
High-yield fact for exams
Atropine reverses muscarinic effects in poisoning.
Gastrointestinal Tract (GIT) Drugs
Quick Fact
PPIs are most effective acid suppressants.
Complete Coverage
Anti-ulcer Drugs
- H2 blockers (ranitidine)
- PPIs (omeprazole) – irreversible pump inhibition
Antiemetics
Ondansetron (5HT3 antagonist), metoclopramide (prokinetic)
Laxatives
Bulk (psyllium), osmotic (lactulose), stimulant (bisacodyl)
High-yield fact for exams
PPIs take 3–4 days for full effect.
Antimicrobial Drugs
Quick Fact
Penicillin targets cell wall synthesis.
Complete Coverage
Classification Overview
- Beta-lactams: penicillins, cephalosporins
- Aminoglycosides: gentamicin (protein synthesis)
- Macrolides: erythromycin (protein synthesis)
- Fluoroquinolones: ciprofloxacin (DNA gyrase)
Resistance Concerns
MRSA, ESBL producers
High-yield fact for exams
Vancomycin for MRSA.
