- Early, Late and Variable Decelerations, Sorted by Mechanism
Head compression, uteroplacental insufficiency and cord compression. Learn the mechanism and the timing stops needing memorisation.
- Fetal Heart Rate Categories One, Two and Three
Three tiers with strict definitions, and the third one hinges on a conjunction most people drop when they quote it.
- Postpartum Hemorrhage and the Four Ts, Ranked by Frequency
Tone, trauma, tissue, thrombin. The published frequencies are lopsided enough that the ranking is genuinely useful at the bedside.
- Eclampsia Warning Signs and the Seizures That Give None
Most cases are preceded by premonitory signs. A substantial minority are not, and the published figures say both things at once.
- HELLP Syndrome and the Cases That Hide in Plain Sight
A meaningful share of cases arrive without hypertension or proteinuria, which is exactly why the symptom pattern matters so much.
- Preeclampsia Without Proteinuria Is Still Preeclampsia
New hypertension plus any one of several findings meets the definition. Waiting for protein in the urine is an outdated instinct.
- Severe Features and the Shortcut for 160 Over 110
At severe-range pressures the confirmation interval collapses to minutes so treatment is not delayed. That exception is frequently tested.
- Preeclampsia Diagnostic Criteria in Plain Numbers
Two blood pressure readings, a minimum interval between them and a gestational age boundary. All three have to be present.
- The Apgar Backronym Arrived a Decade After the Score
Appearance, pulse, grimace, activity, respiration was invented later by two other physicians. Useful memory aid, inaccurate history.
- Apgar Timing: One Minute, Five Minutes and Beyond
Two scheduled scores for every infant, and a repeat interval when the five-minute score is low. Also one extra step at a lower threshold.
- What the Apgar Score Does and Does Not Predict
It was designed in 1952 to guide immediate care. The published guidance is blunt about what it must never be used to diagnose.
- A PN-First Drug Class List Worth Studying
Built from the PN test plan category rather than trimmed from an RN list, and weighted toward what PN candidates administer and monitor.
- Vancomycin and Aminoglycosides Tell Two Different Monitoring Stories
One class has a published level with units. The other has monitoring requirements but no universally agreed target, and that matters.
- Benzodiazepines, GABA and What Monitoring Actually Means
They only work where GABA is already present, which explains both their safety margin and the risk when opioids are added.
- Serotonin Syndrome Versus NMS in Four Clean Contrasts
Drug class, onset speed, muscle findings and resolution time. Four axes separate these two better than any list of symptoms.
- Neuroleptic Malignant Syndrome and Its Classic Tetrad
Fever, rigidity, altered mental status and autonomic instability, developing over days rather than hours. Timing is the tell.
- Antipsychotics and the Dementia Boxed Warning
A class-wide FDA warning with two dates attached. The dates are safe to cite; the relative risk figures floating around are not.
- Corticosteroid Adverse Effects, Organised by Body System
Bone, gut, eye and mind. Several of these have published dose thresholds, which makes them unusually answerable.
- Corticosteroids and Why Tapering Is Not Optional
Stopping abruptly after chronic use is dangerous for a reason you can explain from physiology rather than memorise as a rule.
- Loop Versus Potassium-Sparing Diuretics
The difference that matters most for exam questions is what happens to potassium, and it moves in opposite directions.
- Calcium Channel Blockers and Nitrates, Side by Side
Both lower the workload on the heart by different routes. Reading them together makes each one easier to keep straight.
- Beta Blockers and What Changes With Selectivity
Whether a beta blocker touches beta-2 receptors decides which patients it is risky in. That is the axis most questions turn on.
- ACE Inhibitors: the Cough, the Potassium and Pregnancy
Three consequences flow straight from one mechanism, and one of them is an absolute contraindication rather than a caution.
- Flumazenil and Why Reversal Is Never Automatic
Reversing a benzodiazepine can trigger seizures, and there are situations where it is the wrong move entirely.
- Insulin Onset, Peak and Duration, Read as a Timeline
Sourced figures are more precise than the rounded ones most study guides print. Reading them as a timeline makes hypoglycemia timing obvious.
- Naloxone Wears Off First and That Is the Whole Problem
Its half-life is shorter than most opioids, which is why monitoring continues long after the patient wakes up.
- Lithium Interactions That Quietly Raise the Level
Common drugs a patient can start without thinking about it will push lithium up. That is often what the stem is really testing.
- Lithium Baseline Workup and the Monitoring Schedule
Renal and thyroid function before you start, an ECG over a certain age, then trough levels on a published schedule.
- Potassium and Digoxin Are Dangerous in Both Directions
Low potassium raises toxicity risk, and acute toxicity can drive potassium up. The relationship runs both ways and both ways are tested.
- Digitalis Effect Is Not the Same as Digoxin Toxicity
An expected ECG change on therapy is not evidence of poisoning. Exam items are built on candidates confusing the two.
