NLE Med-Surg Priority Frameworks: ABC, Maslow, Safety

Adult med-surg is where the NLE stops being kind. It drops you into adult care scenarios with three reasonable options and asks which one comes first. If you don't have a working priority framework, you'll burn extra seconds on every item, and across a 2-hour paper that adds up fast. This guide builds the priority engine that pays off on these items.

First, a correction many review materials still get wrong: on PRC's current programme, NP II is not Med-Surg. NP II is care of the mother and adolescent plus human growth and development (see our NP II maternal care guide). Adult med-surg content now sits mainly in NP III (surgery, oxygenation, fluid and electrolytes, infectious, inflammatory and immunologic response, cellular aberrations) and NP IV (nutrition, gastro-intestinal, metabolism and endocrine, perception and coordination), with life-threatening, high-acuity and emergency care in NP V. We'll cover the three frameworks that solve most med-surg priority items — ABC, Maslow, and safety-first — then the content blocks where they get applied.

Where Med-Surg Content Sits on the NLE

PRC names the problem areas in each NP title but doesn't publish item counts per body system. Going by those titles:

Cardiovascular and respiratory — heart failure, MI, arrhythmias, hypertension, COPD, asthma, pneumonia, TB, ARDS. Oxygenation problems: NP III.
Fluid, electrolyte and renal problems — AKI, CKD, dialysis, fluid balance. Fluid and electrolytes: NP III.
Perioperative — pre-op, intra-op, post-op care. Surgery: NP III.
Oncology and immunology — chemo, radiation, HIV, autoimmune. Cellular aberrations and immunologic response: NP III.
Endocrine and metabolic — diabetes, thyroid, adrenal, pituitary. Metabolism and endocrine: NP IV.
GI and hepatic — peptic ulcer, IBD, cirrhosis, pancreatitis. Nutrition and gastro-intestinal: NP IV.
Neuro and sensory — stroke, ICP, seizures, eye and ear problems. Perception and coordination: NP IV.
Emergencies and multi-organ problems — cardiac arrest, shock, acute deterioration. Life-threatening and high-acuity care: NP V.

Pharmacology is integrated into every test, and most of these items are framed as priority scenarios.

The Three Priority Frameworks

Memorise these three. Apply them in this order. Most med-surg priority items resolve quickly when you do.

Framework 1: ABC (Airway, Breathing, Circulation)

Always run ABC first. If any option addresses an airway compromise, that wins. If two options address airway, the more invasive one wins (suction beats reposition if there's audible gurgling). Breathing comes second — oxygen, repositioning, breath sound assessment. Circulation third — bleeding, pulses, BP, perfusion.

The rule: if the patient is stable, ABC doesn't apply. Move to Maslow. If the patient is unstable, ABC overrides everything — including pain management, anxiety, and education.

Framework 2: Maslow's Hierarchy

For stable patients, Maslow ranks the options. Physiological needs first (airway, oxygen, food, fluid, elimination, comfort, rest). Then safety (fall risk, infection control, medication safety). Then psychosocial (anxiety, family, education, dignity).

The trap: reviewers see an emotional fact pattern and pick the empathetic option. Wrong. If a post-op patient is anxious AND hasn't voided in eight hours, you address the bladder before the anxiety. Physiological always beats psychosocial.

Framework 3: Safety-First

When ABC and Maslow tie, safety breaks the tie. Fall prevention, medication right-checks, isolation precautions, suicide precautions. Safety-first items test whether you can spot a delegation error or an unsafe practice — even when the action looks therapeutic on paper.

Cardiovascular: A Core Oxygenation Block

The recurring patterns:

Acute MI

MONA — Morphine, Oxygen, Nitroglycerin, Aspirin. Aspirin is given first (chewed, not swallowed) for the antiplatelet effect.
STEMI vs NSTEMI — STEMI gets cath lab within 90 minutes (door-to-balloon).
Troponin rises 3–4 hours after onset, peaks at 24, stays elevated for 7–14 days.

Heart Failure

Left-sided — pulmonary congestion (crackles, dyspnea, orthopnea, frothy pink sputum).
Right-sided — systemic congestion (JVD, peripheral edema, hepatomegaly, ascites).
Priority position — high Fowler's for pulmonary edema. Legs dependent if not contraindicated.
Diuretic teaching — daily weights, low sodium, monitor potassium with loop diuretics.

Arrhythmias

V-fib and pulseless V-tach — defibrillate immediately. CPR while waiting.
Stable V-tach — amiodarone. Synchronised cardioversion if symptomatic.
Asystole — CPR and epinephrine. Don't defibrillate asystole; there's no rhythm to convert.
SVT — vagal manoeuvres first (if stable), then adenosine.

Respiratory: The Asthma and COPD Patterns

Asthma

Acute attack — high Fowler's, oxygen, short-acting beta agonist (albuterol nebuliser), then corticosteroid. The order matters because each step buys time for the next. Status asthmaticus — silent chest is worse than wheezing; the airways are too narrow to make sound.

COPD

Chronic CO2 retention blunts the normal CO2 drive to breathe, so breathing leans on the hypoxic drive. Oxygen target is SpO2 88–92%, not 95%. Over-oxygenating a COPD patient can cause CO2 narcosis. Pursed-lip breathing prolongs expiration; tripod position maximises accessory muscle use.

TB

Airborne precautions — N95, negative-pressure room. Treatment is RIPE — Rifampin, Isoniazid, Pyrazinamide, Ethambutol — for at least 6 months. Three consecutive negative sputum smears mark non-infectious status. Rifampin turns body fluids orange; warn the patient.

Endocrine: The Diabetes Cluster

Diabetes is the anchor of the metabolism and endocrine content in NP IV.

Hypoglycaemia vs Hyperglycaemia

Hypoglycaemia (under 70 mg/dL) — cold, clammy, confused, tachycardia, tremor. Treatment: 15g fast-acting carb, recheck in 15 minutes (the 15-15 rule). If unconscious — IV dextrose or IM glucagon.

Hyperglycaemia — warm, dry, polyuria, polydipsia, polyphagia, fruity breath if ketotic. DKA: insulin drip, fluids, potassium replacement (insulin drives K+ into cells, so monitor closely).

Insulin Mixing

Clear before cloudy — draw regular (clear) before NPH (cloudy). Never mix insulin glargine with anything. Memorise onset-peak-duration:

Rapid (lispro) — onset 15 min, peak 1 hr, duration 3–4 hr.
Short (regular) — onset 30 min, peak 2–3 hr, duration 6–8 hr.
Intermediate (NPH) — onset 2 hr, peak 6–8 hr, duration 12–18 hr.
Long (glargine) — onset 1 hr, no peak, duration 24 hr.

Renal: Dialysis and Fluid Balance

Hemodialysis vs peritoneal — hemo is faster, riskier, requires AV fistula or graft. Peritoneal is slower, gentler, lets the patient ambulate. Access care: never take BP or draw blood from the fistula arm; auscultate for bruit and palpate for thrill before each session. Dialysate temperature matters for peritoneal — body temperature, infused over 10 minutes.

Neurological: ICP and Stroke

Increased ICP

Cushing's triad — increasing systolic BP, widening pulse pressure, bradycardia, irregular respirations. Late sign. Earliest sign of ICP increase: change in level of consciousness. Position: HOB 30 degrees, neutral neck, avoid hip flexion. Avoid suctioning longer than 15 seconds; pre-oxygenate first.

Stroke

tPA window — 3 to 4.5 hours from symptom onset for ischaemic stroke. Get a CT first to rule out haemorrhagic. FAST screening — Face droop, Arm weakness, Speech difficulty, Time. Right brain stroke causes left-sided weakness; left brain stroke causes aphasia.

Perioperative: The Three Phases

Pre-op

Informed consent verified. NPO 6–8 hours. Skin prep, anti-embolism stockings. Pre-op checklist signed. Voiding before transport. Identify allergies, prosthetics, and the surgical site.

Intra-op

The circulating nurse counts sponges, sharps, and instruments at the start, before closure, and at the end. Time-out before incision — patient identity, surgical site, planned procedure.

Post-op

Priority assessment in PACU: airway first. Then breathing, circulation, level of consciousness, surgical site, drains, pain. Atelectasis is the most common post-op pulmonary complication; prevent with incentive spirometry, deep breathing, and early ambulation.

FAQ

Is ABC always the right priority framework?

For unstable patients, yes. For stable patients, Maslow takes over. The signal is in the stem — words like "acute", "sudden", "unresponsive", "struggling to breathe" trigger ABC.

How much pharmacology is in the med-surg papers?

PRC doesn't publish a figure, but its programme integrates pharmacology into every Nursing Practice test, so many items embed a medication. Know the major drug classes (beta blockers, ACE inhibitors, diuretics, anticoagulants, insulins) and their priority side effects.

Do I need to memorise lab values?

Yes — at least the critical ones. Sodium, potassium, BUN, creatinine, glucose, troponin, BNP, INR, hemoglobin, hematocrit, platelets, WBC. Items frame fact patterns around abnormal values.

What's the most overlooked block?

Perioperative. Reviewers focus on diseases and skip pre/post-op care — yet surgery is the first problem area named in NP III's title, and the principles are stable and learnable.
