NLE Emergency & Critical Care NursingShock, Sepsis & Multi-Organ DysfunctionMemory Anchors

If you keep missing Shock, Sepsis & Multi-Organ Dysfunction items on your NLE mocks despite having read the notes, the gap is usually recall speed. Memory anchors close that gap. These Shock, Sepsis & Multi-Organ Dysfunction mnemonics have been tuned to the kinds of triggers Professional Regulation Commission (PRC) — Board of Nursing builds into NLE Emergency & Critical Care Nursing questions.

Exam context

On the NLE 2026, the Emergency & Critical Care Nursing subtest carries a "Core" weight in Professional Regulation Commission (PRC) — Board of Nursing's pattern. Shock, Sepsis & Multi-Organ Dysfunction lands at position 3rd out of 5 in the standard review order. Target score is 75% weighted average with no sub-test below 60%, and roughly 50 items come from Emergency & Critical Care Nursing on a typical NLE paper.

Shock, Sepsis & Multi-Organ Dysfunction - Memory Anchors

Memory techniques transform abstract clinical facts into vivid, emotionally charged mental images that your brain stores far more reliably than plain text. Research in cognitive psychology shows that encoding information through stories, analogies, rhymes, and visual associations activates multiple brain regions simultaneously — making retrieval faster, stronger, and more automatic under exam pressure. For NLE preparation, where you must recall dozens of clinical parameters, drug names, and sequence-dependent protocols under time pressure, a well-built memory anchor is the difference between a confident recall and a painful blank. These anchors use Filipino cultural references, clinical scenarios, and creative imagery to lock every key concept about Shock, Sepsis, and MODS firmly into long-term memory. Work through them actively — say them aloud, sketch them, and test yourself with the recall triggers. Active rehearsal of these anchors is what makes them permanent.

Classification of Shock

Concept

The Four Classes of Shock: Hypovolemic, Cardiogenic, Distributive, Obstructive

Anchor Id

A1

Difficulty

easy

Memory Aid

Think of the word 'HCDO' — pronounce it like 'Hayco-Do' — as in 'Hay, co, do something, the patient is in shock!' H = Hypovolemic (lost volume), C = Cardiogenic (pump broke), D = Distributive (vessels too wide), O = Obstructive (road blocked). Imagine a Filipino tricycle (circulatory system): H = walang gasolina (no fuel/volume), C = nasira ang makina (broken engine/heart), D = bukas lahat ng daan (all roads dilated), O = may harang sa daan (roadblock/obstruction).

Anchor Type

acronym

Why It Works

The acronym HCDO creates a phonetic hook, and the tricycle analogy maps each abstract shock type onto a familiar Filipino transportation scenario, making it instantly visualizable.

Example Usage

Question: A patient arrives after a stabbing with BP 80/50, HR 130, cool clammy skin, flat neck veins. What class of shock? — Trigger HCDO: H = Hypovolemic. Flat neck veins = low preload = lost volume. Answer: Hypovolemic shock.

Distributive Shock - Neurogenic

Concept

Neurogenic Shock triad: Hypotension + Bradycardia + Warm Dry Skin

Anchor Id

A2

Difficulty

medium

Memory Aid

Neurogenic shock is the REBEL of shocks — it breaks every rule. ALL other shocks are tachycardic (heart races to compensate). But neurogenic shock says 'Hindi ako susunod!' (I will not follow!) — the sympathetic nervous system is cut off by spinal cord injury above T6, so the heart cannot speed up. Picture a broken electric fan: the power cable (sympathetic nerves) is cut. The fan (heart) runs slow. The body stays warm because the blood vessels cannot constrict. 'Cut cord = slow heart + warm body = REBEL shock.'

Anchor Type

analogy

Why It Works

The 'rebel' framing makes bradycardia memorable as the one exception. The analogy of cutting a power cord is concrete and mechanistic — it explains WHY bradycardia occurs, not just that it does.

Example Usage

Question: A patient with C5 spinal cord injury has BP 80/60, HR 52, warm dry skin. What type of shock? — Recall the REBEL: bradycardia + warm skin + hypotension after spinal injury = Neurogenic shock.

Recall Trigger

Which shock breaks the tachycardia rule? The REBEL — cut cord, slow heart.

Distributive Shock - Anaphylactic

Concept

Anaphylactic Shock: Priority drug is Epinephrine 0.3–0.5 mg IM (1:1000)

Anchor Id

A3

Difficulty

medium

Memory Aid

Remember 'EPI FIRST, EPI FAST!' — Epinephrine is the priority. For the dose: think '3 to 5 in the thigh to stay alive' — 0.3 to 0.5 mg. The concentration 1:1000 means ONE milligram per ONE THOUSAND milliliters — it is the IM concentration. Do NOT confuse with 1:10,000 which is IV for cardiac arrest. Memory peg: 'IM = 1:1,000 = three to five = THIGH = ALIVE.'

Anchor Type

mnemonic

Why It Works

The rhyme 'three to five, thigh, alive' creates a rhythmic chain that encodes dose, route, and site simultaneously. The contrast with 1:10,000 prevents the most common exam error.

Example Usage

Question: A patient develops urticaria, bronchospasm, and BP drop after a bee sting. What is the priority intervention? — Recall: EPI FIRST! → epinephrine 0.3–0.5 mg IM (1:1000) into the anterolateral thigh.

Recall Trigger

Anaphylaxis → EPI FIRST! → Thigh → 3 to 5 → Alive → 1:1000

Obstructive Shock

Concept

Obstructive Shock requires MECHANICAL RELIEF — not just fluids and drugs

Anchor Id

A4

Difficulty

medium

Memory Aid

Imagine Dr. Reyes pouring bag after bag of IV fluid into a patient with cardiac tamponade. The patient keeps deteriorating. The senior nurse grabs her arm: 'Doc, you cannot fill a car whose radiator hose is pinched! You need to REMOVE THE BLOCK.' The obstruction (tamponade, tension pneumothorax, massive PE) is a physical roadblock — no amount of fluid or vasopressor will fix a mechanical problem. The solution is mechanical: pericardiocentesis for tamponade, needle decompression + chest tube for tension pneumothorax, thrombolysis/embolectomy for massive PE.

Anchor Type

micro_story

Why It Works

The story creates an emotional scene (frustration, the expert correction) that the brain tags as important. The radiator hose analogy makes the mechanical nature of obstructive shock viscerally clear.

Example Usage

Question: A trauma patient has hypotension, absent breath sounds on the right, tracheal deviation to the left. What is the priority intervention? — Recall: Obstructive (tension pneumothorax) → mechanical relief → needle decompression at 2nd intercostal space, midclavicular line.

Recall Trigger

Pinched hose → cannot fill → must REMOVE THE BLOCK.

Cardiogenic Shock

Concept

Cardiogenic Shock: DO NOT fluid overload — use inotropes and reduce afterload

Anchor Id

A5

Difficulty

hard

Memory Aid

Cardiogenic shock is like a PALYA (exhausted) basketball player whose legs (ventricles) are already waterlogged and cramping. If you give him MORE water (IV fluids), he drowns — his already-failing legs cannot pump even harder. Instead, you give him a stimulant (dobutamine = inotrope to pump harder) and reduce the weight he's carrying (reduce afterload with vasodilators). Key contrast: Hypovolemic patient is THIRSTY — give fluids. Cardiogenic patient is WATERLOGGED — give inotropes, not floods.

Anchor Type

analogy

Why It Works

The Filipino sports analogy (palya na player) creates a vivid contrast between hypovolemic (thirsty) and cardiogenic (waterlogged) that directly prevents the most dangerous exam and clinical error.

Example Usage

Question: Post-MI patient has BP 85/60, HR 118, crackles bilaterally, JVD, elevated CVP. What is the treatment priority? — Recall: Waterlogged player (cardiogenic) → dobutamine (inotrope), cautious diuresis; do NOT bolus fluids.

Recall Trigger

Palya player + waterlogged = inotropes, NOT fluids.

Stages of Shock

Concept

Stages of Shock in order: Initial → Compensatory → Progressive → Refractory

Anchor Id

A6

Difficulty

easy

Memory Aid

Use the acronym 'I Can Prevent Reversal' — I = Initial (cells go anaerobic, no visible signs), C = Compensatory (tachycardia, vasoconstriction, BP still normal — this is the GOLDEN WINDOW), P = Progressive (BP falls, organs fail — last real chance), R = Refractory (irreversible, death follows). Story peg: 'I Can Prevent Reversal' — the nurse who catches shock in the Compensatory stage CAN Prevent the Refractory outcome.

Anchor Type

acronym

Why It Works

The acronym encodes both the sequence AND the clinical message (act in stage C). The mnemonic sentence is a call to action, which gives it emotional weight.

Example Usage

Question: In which stage of shock is the blood pressure most likely still within normal limits? — Recall: I C P R → Compensatory stage (C) — tachycardia and vasoconstriction maintain BP temporarily.

Recall Trigger

I Can Prevent Reversal — catch it at C or lose the patient at R.

Stages of Shock - Compensatory

Concept

Compensatory Stage: Rising respiratory rate and narrowing pulse pressure are earliest reliable warnings

Anchor Id

A7

Difficulty

hard

Memory Aid

Picture a dashboard in your mind. The BP gauge looks fine (deceiving!). But two WARNING LIGHTS are blinking: (1) a TACHYPNEA light — the patient is breathing faster (RR rising), and (2) a NARROW PULSE PRESSURE light — the difference between systolic and diastolic is shrinking (e.g., 110/90 instead of 120/80). These are your earliest alarms BEFORE the BP gauge crashes. Imagine the Filipino jeepney driver who sees oil and engine lights blinking BEFORE the engine stops — act on the warning lights, not the final crash.

Anchor Type

visual_association

Why It Works

The dashboard metaphor transforms two abstract hemodynamic changes into concrete visual warning lights. The jeepney analogy is culturally resonant for Filipino students.

Example Usage

Question: A post-op patient's BP is 118/98 mmHg, RR 24/min, HR 105/min, skin slightly cool. Is this patient in shock? — Recall: Warning lights! Narrowing pulse pressure (118-98 = 20) + rising RR = Compensatory stage shock despite 'normal' BP.

Recall Trigger

Dashboard warning lights blinking: tachypnea light + narrow pulse pressure light = compensatory shock.

SIRS Criteria: 2 of 4 — Temperature, Heart Rate, Respiratory Rate, WBC

Anchor Id

Difficulty

medium

Memory Aid

Remember 'THRW' — pronounced like 'THROW' — as in the body is THROWING an inflammatory fit. T = Temperature (>38°C or <36°C), H = Heart Rate (>90/min), R = Respiratory Rate (>20/min), W = White Blood Cell count (abnormal: >12,000 or <4,000 or >10% bands). Need 2 of these 4 to call it SIRS. Rhyme: 'If two of THRW, SIRS is true!'

Anchor Type

mnemonic

Why It Works

THRW creates a near-word (throw) that is both phonetically memorable and metaphorically appropriate (body 'throwing' a systemic inflammatory response). The rhyme creates a two-step decision rule.

Example Usage

Question: A patient has T 39.1°C, HR 98/min, RR 22/min, WBC 14,000. Does this meet SIRS criteria? — Recall THRW: T = YES (>38), H = YES (>90), R = YES (>20), W = YES (>12,000). All 4 met — SIRS is confirmed.

Recall Trigger

Body THROWING an inflammatory fit → THRW → 2 of 4 = SIRS.

Sepsis - qSOFA

Concept

qSOFA Criteria: RR ≥22, Altered Mentation, SBP ≤100

Anchor Id

A9

Difficulty

medium

Memory Aid

qSOFA = 'Quick Sofa Check' — imagine a patient lying on a sofa, and you do a QUICK check: (1) Are they breathing too fast? (RR ≥22) — 'Hinahabol ang hininga' (gasping for breath); (2) Are they confused? (Altered mentation) — 'Hindi makapag-isip nang maayos' (cannot think clearly); (3) Is the systolic BP low? (≤100 mmHg) — 'Bagsak ang presyon' (pressure dropped). 2 of 3 = HIGH RISK for sepsis. Shortcut: 'RAS — Respiration, Awareness, Systolic' — if 2 of RAS are off, sepsis is likely.

Anchor Type

mnemonic

Why It Works

The Filipino vernacular descriptions create vivid mental images of each criterion. The RAS acronym provides a three-item chunk that is easier to retrieve than the qSOFA name alone.

Example Usage

Question: A febrile patient has RR 24/min, GCS 13, BP 96/60 mmHg. Does this meet qSOFA? — Recall RAS: R = YES (24≥22), A = YES (GCS 13 = altered), S = YES (96≤100). 3/3 met — high risk for sepsis.

Recall Trigger

Quick sofa check → RAS: Respiration ≥22, Awareness altered, Systolic ≤100 → 2 of 3 = high risk.

Septic Shock Definition

Concept

Septic Shock definition: Needs vasopressors for MAP ≥65 AND lactate >2 mmol/L despite adequate fluids

Anchor Id

A10

Difficulty

hard

Memory Aid

Septic shock is like a DAMAGED WATER PIPE SYSTEM in a Manila flood: (1) You have pumped in TONS of water (adequate fluid resuscitation done), but (2) the pressure in the pipes (MAP) is still too low because the pipes are too leaky and dilated (vasodilation), so (3) you need a PRESSURE BOOSTER (vasopressor) to force the MAP up to at least 65, AND (4) the acid in the water (lactate >2) proves the cells are still suffocating. Both conditions must be present — the 'pressure booster needed despite water' + the 'acid in the water.'

Anchor Type

analogy

Why It Works

The water pipe system analogy maps the abstract hemodynamic definition onto a concrete, visualizable system. The two-part requirement (vasopressors AND elevated lactate) is encoded as two simultaneous problems.

Example Usage

Question: A sepsis patient received 30 mL/kg crystalloid. BP 82/50, MAP 61, lactate 3.1 mmol/L. Is this septic shock? — Recall: MAP <65 needs vasopressor + lactate >2 despite fluids = YES, septic shock.

Recall Trigger

Flooded Manila pipes: booster needed (vasopressor for MAP ≥65) AND acid in water (lactate >2) despite fluids = SEPTIC SHOCK.

Sepsis Bundle (Hour-1): Lactate, Blood Cultures BEFORE Antibiotics, Antibiotics, Fluids, Vasopressors

Anchor Id

A11

Difficulty

medium

Memory Aid

Remember 'LBAFL' — pronounced 'LABAL' (like writing a LABEL on the patient's sepsis management plan). L = Lactate (measure it), B = Blood cultures BEFORE antibiotics (never after!), A = Antibiotics broad-spectrum (start ASAP), F = Fluids 30 mL/kg crystalloid, L = Last vasopressor (norepinephrine) if MAP still <65. The critical sequence rule: B comes BEFORE A — Cultures BEFORE Antibiotics. But do not DELAY antibiotics chasing cultures.

Anchor Type

acronym

Why It Works

LABAL is a Filipino-resonant word (label/label) that creates a strong memory peg. The B-before-A sub-rule is explicitly encoded in the acronym order.

Example Usage

Question: A patient is diagnosed with sepsis. In what order should the nurse initiate bundle elements? — Recall LABAL: Lactate first, then Blood cultures (before antibiotics!), then Antibiotics, then Fluids 30 mL/kg, then vasopressors if MAP still <65.

Recall Trigger

LABAL: write the sepsis label — Lactate, Blood cultures, Antibiotics, Fluids, Last-resort vasopressor.

Septic Shock Management

Concept

Norepinephrine is the FIRST-LINE vasopressor in septic shock

Anchor Id

A12

Difficulty

easy

Memory Aid

Remember 'NORA goes FIRST to the Sepsis Party.' NORA = NORAdrenergic = NORepinephrine. She is the VIP guest who arrives first (first-line vasopressor). Other drugs like dopamine and phenylephrine come later or are not preferred. Bonus: Norepinephrine's mechanism — it causes powerful vasoconstriction (alpha-1) with mild cardiac stimulation (beta-1), which is exactly what septic shock needs: raise the MAP without dangerously speeding up an already-stressed heart.

Anchor Type

mnemonic

Why It Works

Naming the drug 'NORA' and making her a VIP party guest creates a persona — our brains remember people better than drug names. The mechanism brief is embedded as logical justification, strengthening retention.

Example Usage

Question: A septic shock patient's MAP remains 58 mmHg after 30 mL/kg crystalloid. Which vasopressor should the nurse prepare to administer first? — Recall NORA: Norepinephrine is first-line in septic shock.

Recall Trigger

NORA goes FIRST to the sepsis party = Norepinephrine is first-line vasopressor.

Anchor Id

A13

Difficulty

medium

Memory Aid

Imagine a row of dominoes in the ICU. The FIRST domino to fall is the LUNGS — they develop ARDS (acute respiratory distress syndrome), the patient needs a ventilator. That fall pushes the KIDNEY domino — creatinine rises, urine drops (AKI). The kidney domino hits LIVER — jaundice appears. Liver hits CLOTTING — DIC starts, the patient bleeds everywhere. Clotting hits GUT — bowel sounds disappear, ileus, bacterial translocation. Finally GUT hits HEART — cardiac dysfunction. Each domino = one organ. MODS = the whole domino chain has fallen. The only way to stop it: catch and stop the FIRST domino (treat shock and sepsis early).

Anchor Type

micro_story

Why It Works

The domino chain provides a concrete visual sequence for the order of organ failure. The moral (stop the first domino) encodes the prevention message simultaneously.

Example Usage

Question: Which organ system typically fails first in MODS following septic shock? — Recall domino chain: first domino = LUNGS (ARDS).

Recall Trigger

ICU dominoes: Lungs → Kidneys → Liver → Clotting → Gut → Heart = MODS.

Memory Aid

Remember 'DIC Labs: DOWN DOWN DOWN UP' — Platelets DOWN, Fibrinogen DOWN, PT/aPTT DOWN (meaning prolonged/abnormal — values are UP but what's normal is DOWN), D-dimer UP. Or more precisely: 'In DIC, everything that should clot is USED UP (low), but the evidence of clotting (D-dimer) is HIGH.' Mnemonic: 'Platelets and Fibrinogen are BROKE (low/depleted). PT/aPTT are PROLONGED (taking too long). D-dimer is PILED UP (high/elevated).' Short rhyme: 'Platelets and fibrin are spent, PT-aPTT is bent, D-dimer went up — DIC is the event!'

Anchor Type

mnemonic

Why It Works

The rhyme encodes all four lab findings in a single memorable sentence. The explanatory 'used up' logic builds understanding, not just memorization.

Example Usage

Question: A sepsis patient has platelet count 48,000, fibrinogen 110 mg/dL, PT 22 sec, aPTT 58 sec, D-dimer 8.4 mcg/mL. What condition does this suggest? — Recall DIC rhyme: platelets spent (low), fibrinogen spent (low), PT/aPTT bent (prolonged), D-dimer up (elevated) = DIC.

Concept

DIC Paradox: Simultaneous clotting AND bleeding

Anchor Id

A15

Difficulty

hard

Memory Aid

DIC is like a firetruck that is simultaneously on fire. The clotting system (firetruck = supposed to fight fires/bleeding) goes completely haywire: it deploys ALL its water (clotting factors and platelets) fighting tiny fires everywhere in the microvessels (microthrombi throughout the body). By the time a REAL fire (major bleeding) starts, the truck has no water left — the patient bleeds from every IV site, every wound, every mucosal surface. Clotting AND bleeding at the same time. It is always SECONDARY to another cause — sepsis, trauma, obstetric emergency.

Anchor Type

analogy

Why It Works

The paradox of a firetruck on fire encapsulates the paradox of DIC perfectly. The 'ran out of water' explanation mechanistically explains why bleeding occurs after widespread clotting.

Example Usage

Question: What term describes the condition where widespread microvascular thrombosis leads to consumption of clotting factors, resulting in simultaneous bleeding? — Recall: firetruck on fire = DIC (Disseminated Intravascular Coagulation).

Recall Trigger

Firetruck on fire = clotting AND bleeding = DIC paradox.

A16

Difficulty

Memory Aid

The two kidney gods of perfusion monitoring: '65 and half.' MAP must reach 65 (think: 65 is the MINIMUM retirement age — the kidneys retire/fail if MAP drops below 65). Urine output must reach 0.5 mL per kg per hour (half a mL, half a point five — the HALF rule). Together: '65 and HALF keep organs safe.' For a 60 kg patient: 0.5 x 60 = 30 mL/hr minimum urine output. Memory peg: 'Sixty-Five and a Half — if you see these two, the organs are still alive.'

Anchor Type

chunking

Why It Works

Chunking both parameters into a single phrase (65 and half) reduces cognitive load. The retirement age analogy gives 65 an emotional anchor. The worked example for a 60 kg patient provides immediate practical application.

Example Usage

Question: What are the target perfusion parameters when monitoring a patient in septic shock on vasopressors? — Recall: 65 and HALF → MAP ≥65 mmHg; urine output ≥0.5 mL/kg/hr.

Recall Trigger

65 and HALF — MAP ≥65 mmHg and UO ≥0.5 mL/kg/hr.

Memory Aid

For most shock: imagine a patient lying flat with their LEGS UP like a V — blood drains back to the heart (increase preload). Picture it as 'TIPPING the barrel' — rolling liquid to one end (the heart). For cardiogenic shock: the heart is already flooding — you would NOT tip more liquid toward it. Instead, sit the patient UP (semi-Fowler's), so fluid drains away from the lungs. Visual: 'Legs UP for most shocks (fill the pump). Head UP for cardiogenic (empty the pump).'

Anchor Type

visual_association

Why It Works

The two opposite images (legs up vs. head up) create a visual contrast that directly encodes the exception. The barrel-tipping analogy makes preload management concrete.

Example Usage

Question: A patient in distributive (septic) shock has been started on vasopressors. What position should the nurse maintain? — Recall: Most shocks → legs elevated, supine position to maximize venous return.

Recall Trigger

Most shocks → legs UP (fill the pump). Cardiogenic → head UP (empty the pump).

mnemonic

Why It Works

The TACO pun creates an immediately memorable image. The flat vs. stuffed taco contrast simultaneously encodes the key differentiator between hypovolemic and cardiogenic shock.

Example Usage

Nurse Ana is managing a septic patient. She runs to get the blood culture bottles FIRST — 'Kultura muna bago gamot!'

Lactate elevation in shock/sepsis: indicates anaerobic metabolism and inadequate perfusion

Anchor Id

A20

Difficulty

hard

Memory Aid

Lactate is the SMOKE SIGNAL from cells under siege. When cells cannot get enough oxygen (inadequate perfusion), they switch to anaerobic metabolism — like a generator running on the wrong fuel — and produce lactic acid as exhaust. Elevated serum lactate = cells are screaming 'We are burning the wrong fuel! Send oxygen!' A lactate >2 mmol/L is a warning; >4 mmol/L = cells in crisis. The smoke signal is measurable before the blood pressure even crashes — making lactate an EARLY warning of occult shock.

Anchor Type

analogy

Why It Works

The smoke signal analogy is culturally resonant and mechanistically accurate. It frames lactate as a COMMUNICATION from suffering cells, which makes its clinical importance immediately intuitive.

Example Usage

Question: A patient's serum lactate is 4.8 mmol/L but BP is 110/70. Should the nurse be concerned? — Recall: Lactate is a smoke signal — high lactate = occult shock = cells starving for oxygen despite 'normal' BP. Yes, this is urgent.

Recall Trigger

Lactate = smoke signal from oxygen-starved cells. >2 = warning; >4 = crisis.

A8 — THRW: 'If two of THRW, SIRS is true!' T=Temperature, H=Heart rate, R=Respiratory rate, W=WBC.

Formula Mnemonics

Formula

MAP = (Systolic BP + 2 × Diastolic BP) / 3

Mnemonic

MAP = 'One Sys, Two Dias, Divide by Three' — or remember 'S + 2D over 3.' Think: Diastole lasts TWICE as long as systole in each cardiac cycle, so it gets counted TWICE in the MAP formula. 'Dias is double, sys is single, three parts total.'

When To Use

Calculate MAP when assessing adequacy of organ perfusion in shock and sepsis patients. Target MAP in septic shock is ≥65 mmHg. Also used to titrate vasopressor doses. Example: BP 90/60 → MAP = (90 + 2×60)/3 = (90+120)/3 = 210/3 = 70 mmHg.

What Each Part Means

MAP = Mean Arterial Pressure. Systolic BP = peak pressure during ventricular contraction. Diastolic BP = baseline pressure during ventricular relaxation (occurs approximately 2/3 of the cardiac cycle). Dividing by 3 averages the three pressure components across one cardiac cycle.

Formula

Urine Output Target: ≥0.5 mL/kg/hr

Mnemonic

Half a mL per kilo per hour — the HALF-KILO RULE. For a 70 kg adult: 0.5 × 70 = 35 mL/hr minimum. If urine drops below this, perfusion to kidneys is failing. Think: 'Half-kilo or the kidney says goodbye.' This is measured hourly with an indwelling urinary catheter.

When To Use

Used continuously in shock and sepsis management to monitor renal perfusion and response to resuscitation. Applied when titrating IV fluids and vasopressors. Oliguria (<0.5 mL/kg/hr) indicates inadequate perfusion or early acute kidney injury.

What Each Part Means

0.5 mL = minimum urine produced per kilogram of body weight. Per hour = assessment interval. Hourly urine output is the most practical bedside indicator of renal perfusion and overall volume status in shock patients.

Formula

Pulse Pressure = Systolic BP − Diastolic BP (Narrowing is an early shock warning)

Mnemonic

Pulse Pressure = 'How far apart are S and D?' Normal is about 40 mmHg (e.g., 120/80 = 40). Narrowing pulse pressure (less than 25 mmHg, or less than 25% of systolic) = the body is squeezing diastolic UP to compensate. Think: 'S and D getting CLOSER together = shock is sneaking in.' Conversely, a WIDE pulse pressure can indicate distributive shock (vasodilation drops diastolic).

When To Use

Used in early shock assessment when systolic BP may still appear normal. A narrowing pulse pressure (e.g., 100/85 = only 15 mmHg) combined with tachycardia suggests early compensatory shock even with a 'normal' systolic BP.

What Each Part Means

Systolic BP = peak pressure. Diastolic BP = baseline pressure. Pulse pressure = the amplitude of each heartbeat's pressure wave. Normally 30–40 mmHg. Narrowing reflects increased SVR (vasoconstriction compensating for falling cardiac output). Widening reflects decreased SVR (vasodilation in distributive shock).

Formula

Crystalloid Fluid Bolus in Sepsis: 30 mL/kg IV

Mnemonic

Thirty mL per kilo — the '30 for Sepsis' rule. For a 60 kg patient: 30 × 60 = 1,800 mL ≈ 2 liters of normal saline or lactated Ringer's. This is the initial rapid resuscitation dose in the Hour-1 Bundle for sepsis with hypotension or lactate ≥4 mmol/L. Remember: '30 mL per kilo gets the pipeline flowing.' Administer over 30 minutes to 3 hours as directed.

When To Use

Initiated in sepsis/septic shock when MAP <65 mmHg or serum lactate ≥4 mmol/L, as part of the Hour-1 Sepsis Bundle. NOT used as an initial large-volume strategy in cardiogenic shock. Reassess during administration for fluid overload signs (crackles, increased CVP, worsening oxygenation).

What Each Part Means

30 mL = volume of crystalloid per kilogram of patient body weight. Given as a rapid IV infusion (bolus). Normal saline (0.9% NaCl) or Lactated Ringer's are acceptable crystalloids. This is an INITIAL resuscitation dose — reassess frequently and adjust based on patient response (MAP, UO, lactate).

Quick Recall Chains

Chain Title

Sepsis Hour-1 Bundle Sequence

Recall Test

Cover the list and answer: What are the 5 elements of the Hour-1 Sepsis Bundle, in sequence? (Hint: think LABAL and Nurse NORA.)

Memory Chain

Use the story: 'Nurse LABAL knows her sequence. She writes the LABEL on the patient's chart: L = Lactate first (check the smoke signal), then she runs to BLOOD culture (Kultura muna bago gamot!), then she hangs the ANTIBIOTICS within the hour, then she squeezes in FLUIDS (30 per kilo for the pipeline), and finally — if MAP is STILL below 65 — she calls NORA (Norepinephrine) to save the day.' LABAL: Lactate → Blood cultures → Antibiotics → Large fluid bolus → Add NORA (vasopressor).

Items To Remember

  • Measure serum lactate
  • Obtain blood cultures BEFORE antibiotics
  • Administer broad-spectrum antibiotics
  • Rapid crystalloid bolus 30 mL/kg
  • Start vasopressors (norepinephrine) if MAP <65 persists

Chain Title

Stages of Shock in Order

Recall Test

What does I-C-P-R stand for in the stages of shock? At which stage is the blood pressure most likely still normal? At which stage is intervention most effective?

Memory Chain

'I Can Prevent Reversal' — each word starts with the stage letter (I-C-P-R). Tell the story: 'I (Initial — invisible damage begins) Can (Compensatory — catch it here!) Prevent (Progressive — last real chance) Reversal (Refractory — too late).' The message IS the mnemonic: a nurse who catches shock at stage C CAN prevent the Refractory outcome.

Items To Remember

  • Initial stage — anaerobic metabolism, no visible signs
  • Compensatory stage — tachycardia, vasoconstriction, BP maintained
  • Progressive stage — BP falls, organ ischemia
  • Refractory stage — irreversible, death

Chain Title

Order of Organ Failure in MODS

Recall Test

List the typical sequence of organ failure in MODS starting from the first to fail. (Hint: think of the domino chain starting with the breathing organ.)

Memory Chain

Use the domino story chain: 'LUNGS fall first (ARDS — needing a vent), they knock down the KIDNEYS (AKI — creatinine rises), kidneys knock LIVER (jaundice), liver knocks CLOTTING (DIC — bleeding everywhere), clotting knocks GUT (ileus, bacterial translocation), gut finally knocks HEART (cardiac dysfunction).' Acronym for order: 'LKLCGH' — 'Lungs, Kidneys, Liver, Clotting, Gut, Heart' — say it fast as 'LICK-GH'.

Items To Remember

  • Lungs first — ARDS
  • Kidneys — AKI
  • Liver
  • Coagulation system — DIC
  • Gut
  • Heart

Distinguishing Signs of the Three Types of Distributive Shock

Recall Test

A patient has hypotension and tachycardia following surgery for bowel perforation; they have warm skin and a fever. Which distributive shock is this? Now, a different patient has hypotension, HR 48, and warm skin after a fall from a motorcycle causing T4 injury — which type is this?

Memory Chain

Remember 'SNA — Septic, Neurogenic, Anaphylactic — the three warm shocks.' All three have vasodilation (warm skin). The REBEL (Neurogenic) has bradycardia — that is your differentiator. Anaphylaxis has the ALLERGY SYMPTOMS (hives, wheezing) — you can see and hear the cause. Septic has the INFECTION story (fever, source). SNA chain: S = Sick (infection), N = Nerve cut (bradycardia), A = Allergy attack (hives + wheeze).

Items To Remember

  • Septic shock — warm skin, tachycardia, fever or hypothermia, known infection source
  • Neurogenic shock — BRADYCARDIA, warm DRY skin, hypotension, spinal cord injury above T6
  • Anaphylactic shock — urticaria, bronchospasm, angioedema, IgE-mediated allergen exposure

Chain Title

DIC Laboratory Pattern

Recall Test

In a patient with DIC, would you expect the platelet count to be high or low? The D-dimer? The PT? The fibrinogen? (Answer all four from memory using the rhyme.)

Memory Chain

Rhyme chain: 'Platelets and fibrin are SPENT (LOW), PT and aPTT are BENT (PROLONGED), D-dimer WENT UP (HIGH) — DIC is the event!' The logic: DIC consumes all the clotting ingredients (so they run out — LOW), but leaves behind the evidence of all that clotting activity (D-dimer fragments — HIGH). Like a baking disaster where all the flour and eggs are used up (LOW) but the mess of crumbs (HIGH D-dimer) tells the story.

Items To Remember

  • Platelets — LOW (consumed in clots)
  • Fibrinogen — LOW (consumed in clots)
  • PT — PROLONGED (low clotting factors)
  • aPTT — PROLONGED (low clotting factors)
  • D-dimer — HIGH (evidence of clot breakdown)
