HESI Pharmacology Study Tips by Domain
- Verify the “rights” (patient, medication, dose, route, time, documentation, reason, response) and confirm two identifiers—red flag: giving a med before clarifying a missing/illegible order.
- High-alert meds (e.g., insulin, heparin, opioids) require an independent double-check per policy—common trap: skipping the second check when the unit is busy.
- Calculate doses carefully (mg/kg, unit conversions) and recheck if the result seems extreme—priority rule: question any dose that is off by a factor of 10.
- Assess for allergies, contraindications, and key parameters (e.g., BP/HR for antihypertensives, apical pulse for digoxin) before administration—red flag: administering without baseline vitals/labs when required.
- Prevent medication errors with standard precautions: avoid trailing zeros, use a leading zero (0.5 not .5), and don’t use unsafe abbreviations—common trap: misreading “U” as a zero.
- Patient education and monitoring are part of safe administration—priority rule: teach what to report immediately (e.g., rash, swelling, shortness of breath) and reassess for therapeutic effect and adverse reactions after dosing.
- Thrombolytics for acute ischemic stroke have a strict time window (often ≤ 3–4.5 hours from last-known-well)—red flag: uncontrolled BP or recent surgery/bleeding increases hemorrhage risk.
- Antiseizure meds require consistent dosing and monitoring—common trap: stopping abruptly can trigger status epilepticus; prioritize seizure precautions and airway readiness.
- Phenytoin is a vesicant and can cause purple glove syndrome—priority rule: give IV slowly with a dedicated line (compatible fluid) and monitor for hypotension/dysrhythmias.
- Levodopa/carbidopa timing is critical for Parkinson’s symptom control—red flag: high-protein meals can reduce effect, and dopamine antagonists (e.g., many antipsychotics/antiemetics) can worsen rigidity.
- Mannitol or hypertonic saline for increased ICP demands close I&O and labs—contraindication cue: mannitol is risky in anuria/renal failure and can cause pulmonary edema if fluid shifts overload the heart.
- Opioids, benzodiazepines, and other CNS depressants have additive respiratory depression—priority cue: hold and reassess if RR < 12/min or sedation is excessive, and have naloxone available.
- For antihypertensives (especially ACE inhibitors/ARBs), hold and notify the provider if SBP < 90 mmHg or the patient is symptomatic; red flag: new cough/angioedema (ACE inhibitor) or hyperkalemia risk.
- With beta blockers, check apical pulse for 1 full minute and hold if HR < 60 bpm unless otherwise ordered; common trap: masking hypoglycemia symptoms in diabetics.
- For digoxin, hold if apical pulse < 60 bpm and assess for toxicity; red flag: nausea, yellow/green halos, and dysrhythmias — risk increases with hypokalemia (often from loop diuretics).
- On warfarin therapy, monitor INR (typical goal 2–3 for many indications) and reinforce consistent vitamin K intake; red flag: bleeding/bruising or black stools — antidote is vitamin K.
- For heparin/LMWH, watch for HIT (platelet drop) and bleeding; priority rule: protamine sulfate reverses heparin, and IM injections are a common trap that increases hematoma risk.
- With nitrates, avoid concurrent PDE-5 inhibitors (e.g., sildenafil) due to severe hypotension; red flag: headache and dizziness — keep the patient seated and check BP before dosing.
- Beta2-agonists (e.g., albuterol) are rescue meds for acute bronchospasm—red flag is tachycardia/tremor and need for frequent doses (suggests poor control).
- Inhaled corticosteroids are first-line controllers for persistent asthma; common trap is using them PRN—cue: rinse mouth after use to prevent oral candidiasis.
- Anticholinergic bronchodilators (ipratropium/tiotropium) are key in COPD; contraindication cue: caution in narrow-angle glaucoma/urinary retention (monitor for dry mouth).
- Methylxanthines (theophylline) have a narrow therapeutic range; priority rule is to hold/notify for nausea, vomiting, dysrhythmias, or seizures (toxicity) and watch interactions (e.g., macrolides).
- Oxygen in COPD should be titrated to target SpO2 about 88%–92%; red flag is high-flow O2 causing worsening CO2 retention and decreased respiratory drive in chronic retainers.
- For pulmonary embolism therapies, anticoagulants (heparin/warfarin/DOACs) require bleeding surveillance; practical cue: if on heparin, monitor aPTT/anti-Xa and have protamine available for reversal.
- Proton pump inhibitors (e.g., omeprazole) work best when taken 30–60 minutes before breakfast; red flag: long-term use raises risk for C. difficile diarrhea and hypomagnesemia.
- H2 blockers (e.g., famotidine) can cause confusion in older adults and require renal dose adjustment; trap: don’t double up OTC + prescribed acid reducers.
- Antacids interfere with absorption of many meds; priority rule: separate from tetracyclines, fluoroquinolones, and iron by at least 2 hours (often 4 hours for quinolones).
- Sucralfate must be given on an empty stomach and can bind other drugs; cue: hold other meds 2 hours before/after and watch for constipation.
- Antiemetics have signature safety risks—ondansetron can prolong QT and metoclopramide can cause tardive dyskinesia; red flag: involuntary facial/tongue movements require stopping and provider notification.
- Laxative selection hinges on bowel status—avoid stimulant laxatives with suspected obstruction and avoid sodium phosphate products in kidney disease; trap: opioid constipation usually needs a scheduled stimulant + stool softener rather than PRN.
- Insulin safety: rapid/short acting should be given with food available; red flag is hypoglycemia (sweating, tremor, confusion)—treat immediately with 15 g fast carbs if awake or glucagon/IV dextrose if not.
- Basal vs bolus: do not hold long-acting basal insulin just because the patient is NPO; common trap is skipping basal and causing hyperglycemia/ketosis—clarify dose adjustments with the prescriber.
- Thyroid replacement (levothyroxine): give in the morning on an empty stomach and separate from calcium/iron by at least 4 hours; red flag is signs of excess dose (tachycardia, chest pain) especially in older adults.
- Antithyroid meds (methimazole/PTU): priority adverse effect is agranulocytosis—teach to report fever or sore throat immediately and hold the drug pending CBC.
- Corticosteroids: do not stop abruptly after chronic use; common trap is adrenal crisis—watch for hypotension, weakness, and hypoglycemia, and ensure tapering plus stress-dose coverage when ill/surgical.
- Diabetes oral agents: metformin must be held for iodinated contrast and with acute kidney injury/hypoxia; red flag is lactic acidosis (malaise, myalgias, rapid breathing), and sulfonylureas carry hypoglycemia risk if meals are skipped.
- UTI antibiotics: obtain urine culture before first dose when possible and reassess at 48–72 hours—red flag is new flank pain/fever suggesting pyelonephritis or treatment failure.
- Aminoglycosides (e.g., gentamicin) and vancomycin are nephrotoxic—priority rule is to trend BUN/Cr and troughs; common trap is giving doses without holding/adjusting for rising creatinine or low urine output.
- Diuretics: loop diuretics can cause hypokalemia and dehydration—contraindication/red flag is symptomatic hypotension or K+ < 3.5 mEq/L; common trap is not replacing potassium as ordered.
- BPH meds: alpha-1 blockers (tamsulosin) can cause orthostatic hypotension—priority teaching is first dose at bedtime and slow position changes; red flag is syncope/falls in older adults.
- Anticholinergics for overactive bladder (oxybutynin) can precipitate urinary retention—contraindication/red flag is difficulty starting stream or decreasing output, especially in BPH.
- Dialysis/renal failure dosing: many renally cleared drugs require dose reduction or post-dialysis timing—common trap is administering digoxin, insulin, or opioids at usual doses despite reduced GFR, increasing toxicity risk.
- NSAIDs (e.g., ibuprofen, naproxen) can cause GI bleeding and kidney injury—red flag: black/tarry stools or rising creatinine, especially in older adults or dehydration.
- Acetaminophen is first-line for many mild pain scenarios, but hepatotoxicity is dose-related—do not exceed 4 g/day (often 3 g/day for older adults or chronic use) and avoid combining multiple “APAP” products.
- Skeletal muscle relaxants (cyclobenzaprine, methocarbamol) commonly cause sedation and falls—priority rule: avoid alcohol/other CNS depressants and use extra caution in geriatrics.
- Gout therapies have key timing traps—do not start allopurinol during an acute flare, and for colchicine stop and notify the provider for severe diarrhea (toxicity warning).
- Osteoporosis meds require strict administration to prevent harm—alendronate must be taken with plain water on an empty stomach and remain upright 30 minutes (red flag: new dysphagia or chest pain suggests esophagitis).
- Biologics/DMARDs for inflammatory arthritis raise infection risk—hold and notify the provider for fever or signs of infection, and avoid live vaccines while immunosuppressed.
- For topical corticosteroids, use the lowest effective potency and limit duration—red flag for systemic effects is large-area or occlusive dressing use, especially in children.
- For burns, stop the burn, cool with tepid water (not ice), and cover with a clean dry dressing—priority rule: watch for circumferential burns as a compartment syndrome/vascular compromise trap.
- With silver sulfadiazine for burns, screen for sulfonamide allergy and monitor WBC count—contraindication: avoid near term pregnancy/newborns due to kernicterus risk.
- For acne agents (benzoyl peroxide, topical retinoids), expect dryness/peeling and start every other day—common trap: mixing multiple irritating products increases dermatitis and nonadherence.
- With antifungals (topical azoles/terbinafine), treat for 1–2 weeks beyond symptom resolution—red flag: continuing moist, occlusive footwear/clothing leads to recurrence.
- For scabies/pediculosis treatment (permethrin), treat close contacts and decontaminate linens/clothing in hot water—common trap: persistent itching can last weeks and doesn’t always mean reinfestation.
- For systemic corticosteroids, check glucose and infection status first—red flag: fever or new productive cough because steroids can mask infection and worsen hyperglycemia.
- With NSAIDs (e.g., ibuprofen, naproxen), screen for GI bleed risk and renal impairment—trap: combining with anticoagulants or a history of ulcers increases bleeding risk.
- For immunosuppressants (e.g., tacrolimus, cyclosporine), prioritize therapeutic drug levels and renal function—red flag: rising creatinine or tremor suggests toxicity.
- When giving biologics/monoclonal antibodies (e.g., TNF inhibitors), verify TB and hepatitis screening per protocol—trap: starting therapy without screening can precipitate reactivation.
- With antihistamines, assess sedation and anticholinergic effects—priority rule: avoid in older adults with glaucoma/BPH due to urinary retention and blurred vision.
- For epinephrine in anaphylaxis, give IM in the mid-outer thigh and reassess airway/breathing—red flag: delaying epinephrine in favor of antihistamines can be fatal.
- For cytotoxic chemotherapy, verify baseline CBC, renal, and hepatic labs and hold/clarify orders for ANC < 1,500/mm³ or platelets < 100,000/mm³ (common HESI safety trap: giving chemo despite myelosuppression).
- Teach neutropenia precautions and to report fever ≥ 38°C (100.4°F) immediately; red flag: no antipyretics before calling because they can mask infection.
- Manage extravasation risk with vesicants (e.g., anthracyclines, vinca alkaloids) by checking blood return before/during infusion; priority rule: stop infusion and leave the catheter in place if burning/swelling occurs.
- For anthracyclines (e.g., doxorubicin), monitor cumulative dose and cardiac function; red flag: new dyspnea, edema, or decreased EF suggests cardiomyopathy and requires prompt provider notification.
- With cisplatin/carboplatin, prioritize aggressive hydration and strict I&O; red flag: rising creatinine or decreased urine output indicates nephrotoxicity and warrants holding/clarifying the next dose.
- Before starting targeted/immunotherapies, confirm required screening and monitoring (e.g., trastuzumab baseline echo, checkpoint inhibitors for colitis/pneumonitis); contraindication cue: severe diarrhea, cough, or SOB can signal immune-related toxicity, not “just side effects.”
- For SSRIs/SNRIs, prioritize suicide-risk monitoring in the first 1–2 weeks and after dose changes; red flag: new agitation, insomnia, or worsening depression can signal increased risk.
- With MAOIs, enforce tyramine avoidance and a washout (at least 14 days between most antidepressants); red flag: severe headache, diaphoresis, and hypertension suggest hypertensive crisis.
- Lithium has a narrow therapeutic range—hold and notify if toxicity signs appear; red flag: coarse tremor, vomiting/diarrhea, and ataxia often mean elevated lithium, especially with dehydration or NSAID/ACE inhibitor/diuretic use.
- Antipsychotics require vigilance for extrapyramidal symptoms vs. neuroleptic malignant syndrome (NMS); red flag: fever, “lead-pipe” rigidity, and autonomic instability indicate NMS and need immediate action.
- Benzodiazepines and other sedative-hypnotics increase fall and respiratory-depression risk, especially with opioids/alcohol; common trap: giving PRN doses too frequently can cause oversedation and paradoxical agitation in older adults.
- For clozapine, follow required ANC monitoring and teach infection precautions; red flag: sore throat or fever may indicate agranulocytosis and warrants prompt evaluation.
- Glaucoma drops are high-yield: teach punctual occlusion 1–2 minutes after instillation to reduce systemic effects; red flag—atropine/anticholinergics can worsen angle-closure glaucoma.
- Ototoxicity monitoring is critical with aminoglycosides and loop diuretics: report new tinnitus, dizziness, or hearing loss immediately; common trap—combining these drugs increases risk.
- Cataract meds vs postop care: avoid mydriatics unless ordered and remind not to rub the eye; priority rule—postop sudden eye pain, decreased vision, or halos can signal increased IOP.
- Dry eye/ocular allergy therapy: artificial tears are first-line and antihistamine/decongestant drops can cause rebound redness; red flag—don’t use vasoconstrictor drops for more than a few days.
- Hearing aid and cerumen management: avoid instilling OTC ear drops when there is suspected TM perforation or ear tubes; contraindication cue—severe pain with drainage suggests perforation/infection.
- Safety with sensory deficits and CNS meds: sedatives, opioids, and antihistamines increase fall risk in clients with vision/hearing impairment; priority rule—start low, reassess gait/orthostasis after first doses.
- For anaphylaxis, give IM epinephrine in the mid-outer thigh first—red flag: do not delay for IV access or rely on antihistamines as primary treatment.
- Suspected opioid overdose: administer naloxone and support airway/ventilation—trap: naloxone duration may be shorter than the opioid, so re-sedation requires repeat dosing and monitoring.
- Acute chest pain/ACS: chewable aspirin is a priority unless true allergy or active bleeding—contraindication cue: avoid nitrates if recent PDE-5 inhibitor use (e.g., sildenafil) due to severe hypotension risk.
- SVT management: try vagal maneuvers then rapid IV adenosine with immediate saline flush—trap: adenosine can cause brief asystole and is less effective with caffeine/theophylline (may need higher dose per protocol).
- Status epilepticus: benzodiazepines (IV lorazepam or IM/IV midazolam) are first-line emergent meds—red flag: monitor for respiratory depression and be ready for airway support.
- Rapid-sequence intubation meds: etomidate/ketamine for induction and a paralytic (succinylcholine or rocuronium)—contraindication cue: avoid succinylcholine in hyperkalemia risk (burns/crush injury/neuromuscular disease) due to fatal dysrhythmias.
- OTC acetaminophen is a top HESI safety item—red flag for accidental overdose when patients take multiple “cold/flu” products; keep total daily dose ≤ 4,000 mg (lower if liver disease or heavy alcohol use).
- NSAIDs (ibuprofen, naproxen) can cause GI bleed, renal injury, and raise BP—avoid in CKD, active ulcer/bleed, or while on anticoagulants; common trap is combining OTC NSAIDs with prescribed anti-inflammatories.
- Aspirin OTC is not benign—contraindicated in children/teens with viral illness (Reye syndrome) and increases bleeding risk; priority cue: stop and notify provider for black/tarry stools or easy bruising.
- Decongestants (pseudoephedrine/phenylephrine) can worsen hypertension, tachycardia, and glaucoma—red flag if patient has uncontrolled HTN, CAD, or takes MAOIs (risk hypertensive crisis).
- Antihistamines (especially first-generation like diphenhydramine) cause sedation and anticholinergic effects—common trap is use in older adults leading to falls, urinary retention, or confusion; avoid with BPH and narrow-angle glaucoma.
- Herbals/supplements have clinically relevant interactions—priority rule: ask specifically about them; red flags include St. John’s wort (reduces effectiveness of many meds) and ginkgo/garlic (increased bleeding with antiplatelets/warfarin).
- Follow the “rights” of medication administration (patient, drug, dose, route, time, documentation, reason, response) and pause for any mismatch—red flag: skipping two identifiers or administering before checking allergies.
- Use independent double-checks for high-alert meds (e.g., insulin, heparin, opioids, concentrated electrolytes)—common trap: relying on a barcode scan alone instead of verifying dose calculations and pump settings.
- Know route-specific rules: never crush extended-release/enteric-coated meds, and give IM using correct landmark/needle size—contraindication: injecting into an inflamed or poorly perfused site.
- Maintain sterile technique for parenteral meds and IV access, and assess patency before giving IV push—red flag: pain, blanching, or swelling suggesting infiltration/extravasation.
- Time-critical meds (antibiotics, anticoagulants, Parkinson meds, anticonvulsants) should be given within the ordered window—priority rule: when in doubt, clarify timing rather than “catching up” doses close together.
- Document immediately after administration and reassess for therapeutic and adverse effects—common trap: failing to hold and notify the provider for parameters (e.g., low BP/HR before antihypertensives or opioids).
