Digoxin Toxicity
Cardiac glycoside with a narrow therapeutic index. NCLEX often tests early toxicity signs, heart-rate hold parameters, renal clearance, and the hypokalemia connection.

Warfarin vs Heparin
Classic anticoagulant comparison. Know the lab, route, onset, antidote, pregnancy rule, and bridge therapy logic.
View Priority Sheet →Insulin Types NCLEX: Regular, NPH & Lantus
NCLEX insulin questions usually test peak timing, hypoglycemia risk, mixing rules, and what to do when the patient is NPO.
View Priority Sheet →Vancomycin Infusion Reaction
Formerly called Red Man Syndrome. A rate-dependent histamine reaction, not a true allergy.
View Priority Sheet →Phenytoin Nursing Considerations
Narrow therapeutic index anticonvulsant. NCLEX often tests CNS toxicity sequence, albumin correction, gingival hyperplasia, and IV compatibility.
View Priority Sheet →When to Hold Digoxin
Digoxin hold questions test apical pulse, toxicity symptoms, potassium, renal clearance, and whether the nurse recognizes the risk before giving the dose.
View Priority Sheet →Lithium Toxicity
Lithium has a narrow therapeutic index. NCLEX commonly tests early GI toxicity, worsening neurologic signs, dehydration, sodium changes, renal function, and interacting drugs.
View Priority Sheet →Lithium Therapeutic Level
Lithium level questions test whether the nurse knows the memory range, checks trough timing, and notices toxicity risk from dehydration, sodium shifts, renal impairment, or interacting drugs.
View Priority Sheet →Warfarin INR Goals
Warfarin questions usually test INR monitoring, bleeding assessment, vitamin K teaching, pregnancy risk, interacting drugs, and what to do when INR is too high.
View Priority Sheet →Heparin APTT Therapeutic Range
Unfractionated heparin questions test APTT or anti-Xa monitoring, bleeding, platelet drop, HIT clues, rapid onset, and protamine reversal as ordered.
View Priority Sheet →Opioid Overdose and Naloxone
Opioid overdose questions test airway and breathing first, respiratory depression, naloxone response, reassessment, repeat sedation risk, and emergency follow-up.
View Priority Sheet →Morphine Nursing Considerations
Morphine questions test pain reassessment, respiratory depression, sedation, blood pressure, constipation, fall risk, and naloxone as the reversal agent when ordered.
View Priority Sheet →Gentamicin Nursing Considerations
Gentamicin is an aminoglycoside. NCLEX tests nephrotoxicity, ototoxicity, peak/trough timing, renal monitoring, and high-risk symptoms to report.
View Priority Sheet →Regular Insulin vs NPH vs Lantus
Insulin comparison questions test peak timing, hypoglycemia risk, IV regular insulin, cloudy NPH, glargine no-mix rules, and NPO basal insulin traps.
View Priority Sheet →Furosemide Nursing Considerations
Furosemide is a loop diuretic. NCLEX tests potassium loss, fluid volume status, blood pressure, renal function, ototoxicity, and the digoxin-hypokalemia trap.
View Priority Sheet →Beta Blockers
Beta blocker questions test pulse and blood pressure before administration, bradycardia, hypotension, bronchospasm risk, masking hypoglycemia, and not stopping abruptly.
View Priority Sheet →ACE Inhibitors
ACE inhibitor questions test cough, angioedema, hyperkalemia, renal function, blood pressure, pregnancy risk, and interactions with potassium supplements or potassium-sparing drugs.
View Priority Sheet →Acetaminophen Toxicity
Acetaminophen overdose questions test early subtle symptoms, hepatic injury, timing of level, N-acetylcysteine as the antidote, alcohol risk, and hidden duplicate products.
View Priority Sheet →Nitroglycerin Nursing Considerations
Nitroglycerin questions test chest pain priority, blood pressure before dosing, headache, orthostatic hypotension, PDE-5 inhibitor contraindication, and patch safety.
View Priority Sheet →Albuterol vs Salmeterol
Bronchodilator comparison questions test SABA rescue use, LABA maintenance use, acute symptom treatment, inhaled corticosteroid pairing, tremor, tachycardia, and potassium shifts.

Frequently Asked Questions
Questions about Ask Osler, Priority Sheets, and how to use them for NCLEX prep.
What is a Priority Sheet?
A Priority Sheet is a one-page, structured study card for a specific NCLEX pharmacology topic. It covers what to do first, hold parameters, labs to monitor, toxicity signs, and common NCLEX traps — all in under 2 minutes of reading time.
Is Ask Osler free?
Yes. All Priority Sheets are free to read. No login, no paywall, no subscription required. We may add optional premium features in the future, but the core pharmacology sheets will always be free.
