Before We Start
Why this condensed, ten-condition format is worth having on its own
Each of these ten conditions could fill its own multi-page lesson (and several are covered in more depth in other subject areas of this site). This lesson deliberately compresses each one to its single most recognizable presentation pattern and its single most important priority action — a fast-scan reference specifically built for NCLEX recall speed, not comprehensive clinical depth.
💡 The Pattern-Then-Action Structure
Each condition below follows the same two-part structure: the recognizable presentation pattern, then the priority action. This consistent format is itself part of the memorization strategy — once you know to look for "pattern → action" for each condition, the specific content becomes easier to slot in.
Mnemonic
Ten conditions, pattern and action
DKA
Kussmaul respirations, fruity breath, glucose above 250 with ketones
Priority: insulin drip, fluids, and potassium replacement (since insulin drives potassium into cells, risking hypokalemia during correction).
Heart Failure
Crackles (left-sided), edema (right-sided)
Priority: semi-Fowler's positioning, oxygen, and daily weights to track fluid status.
MI
Crushing chest pain
Priority: MONA (Morphine, Oxygen, Nitroglycerin, Aspirin), 12-lead ECG, and troponin.
Stroke
FAST (Face, Arm, Speech, Time)
Priority: CT scan, and tPA if ischemic and within the treatment window.
ARDS
Refractory hypoxemia, bilateral infiltrates
Priority: prone positioning and low-tidal-volume ventilation.
Sepsis
Fever, tachycardia, hypotension
Priority: cultures FIRST, then broad-spectrum antibiotics, then fluids — the sequencing matters, since starting antibiotics before cultures are drawn can compromise the ability to identify the causative organism.
SCI (Cervical) — Autonomic Dysreflexia
Sudden severe hypertension, pounding headache
Priority: sit the patient upright, and find and remove the triggering stimulus (often a full bladder or bowel impaction).
Preeclampsia
BP ≥140/90 plus proteinuria
Priority: magnesium sulfate, and a quiet, low-stimulation room to reduce seizure risk.
Thyroid Storm
Hyperthermia, tachycardia, agitation
Priority: PTU (propylthiouracil), beta blocker, and active cooling.
Addisonian Crisis
Hypotension, hyponatremia, hyperkalemia
Priority: IV hydrocortisone.
💊 Sepsis's "cultures first, then antibiotics" sequencing is one of the most specifically tested details in this whole list — it's a genuine exception to the general instinct to treat the infection as fast as possible, because drawing cultures first preserves diagnostic accuracy without meaningfully delaying treatment.
🏥 Clinical Scenario — Applying the Sepsis Sequencing Correctly
A patient presents with fever, tachycardia, and hypotension, consistent with sepsis. The provider orders blood cultures and broad-spectrum antibiotics.
Recognize the Correct Sequence
Blood cultures should be drawn BEFORE the antibiotics are administered — this specific sequencing preserves the ability to identify the causative organism, which starting antibiotics first would compromise. This is a well-known, specifically tested detail precisely because the instinct to treat as fast as possible can lead to skipping or delaying the cultures unnecessarily.
Execute Efficiently, Not Slowly
The nurse draws the cultures promptly and efficiently, then proceeds immediately to antibiotic administration — this sequencing doesn't mean meaningfully delaying treatment, just correctly ordering two steps that can both happen quickly in succession. "Cultures first" is about sequence, not about introducing unnecessary delay.
Continue With Fluid Resuscitation
Following cultures and antibiotics, the nurse proceeds with fluid resuscitation as the third step in the sepsis priority sequence. Following the full pattern-and-action sequence for sepsis, rather than jumping to whichever intervention seems most urgent first, reflects the specific, tested clinical protocol for this condition.
⚠️ The Trap — Starting Antibiotics Before Drawing Cultures in Suspected Sepsis
The urgency of sepsis management can create pressure to administer antibiotics as fast as possible, potentially skipping or delaying the cultures. But antibiotics given before cultures are drawn can compromise identification of the causative organism, which has real implications for targeted treatment going forward.
The safeguard: Draw cultures first, then proceed immediately to antibiotics — this sequence doesn't meaningfully slow treatment when executed efficiently, and preserves important diagnostic information.
