Pharmacology is one of the most challenging and most important nursing science courses. It appears on every major nursing exam — TEAS Science, NCLEX, ATI Pharmacology, HESI, and all ATI course exams. NurseQuizPrep PhD pharmacology specialists provide systematic, clinically-grounded drug class review.

Cardiovascular Pharmacology

The largest and most tested drug category in nursing pharmacology. Our specialists cover antihypertensives (ACE inhibitors, ARBs, calcium channel blockers, beta-blockers, diuretics), antiarrhythmics, anticoagulants, antiplatelets, statins, and heart failure medications.

• Beta-blockers: hold if HR <60; monitor for hypotension and bronchospasm
• Warfarin: INR monitoring, antidote (vitamin K), drug-food interactions
• Digoxin: narrow therapeutic index (0.5-2 ng/mL), toxicity signs

Antibiotic Pharmacology

Antibiotic classification by mechanism, spectrum, and major clinical uses. Drug-specific adverse effects (aminoglycoside nephrotoxicity, tetracycline photosensitivity, fluoroquinolone tendon rupture risk) and resistance mechanisms.

• Penicillins: cell wall synthesis inhibition; beta-lactamase resistance
• Aminoglycosides: monitor peak and trough levels, audiometry
• Vancomycin: red man syndrome prevention — slow infusion rate

Psychiatric & Neurological Pharmacology

Antidepressants (SSRIs, SNRIs, TCAs, MAOIs), antipsychotics (typical vs. atypical, EPS, NMS), mood stabilizers (lithium, valproate, carbamazepine), anxiolytics (benzodiazepines, buspirone), and anticonvulsants.

• MAOI-tyramine: life-threatening hypertensive crisis — dietary restriction
• Lithium toxicity: narrow index — levels, hydration, sodium intake critical
• Clozapine: weekly WBC for first 6 months — agranulocytosis risk
