Summary Concepts Notes Revision Deep Dive Slides Flashcards Mistakes Cheat Mnemonics Templates

Memory anchors and mnemonic tricks for Fluid, Electrolyte and Acid-Base Imbalances. If you find yourself forgetting key facts from this chapter during NLE mocks, these anchors are your fix. Built for Professional Regulation Commission (PRC) — Board of Nursing's question style and the time pressure of the NLE 2026.

Exam context

On the NLE 2026, the Foundations of Medical-Surgical Nursing subtest carries a "Core" weight in Professional Regulation Commission (PRC) — Board of Nursing's pattern. Fluid, Electrolyte and Acid-Base Imbalances lands at position 1st out of 2 in the standard review order. Target score is 75% weighted average with no sub-test below 60%, and roughly 50 items come from Foundations of Medical-Surgical Nursing on a typical NLE paper.

Fluid, Electrolyte and Acid-Base Imbalances - Memory Anchors

Research in cognitive science shows that vivid, emotionally engaging memory anchors dramatically improve long-term recall — sometimes by 400% compared to rote repetition. For the NLE, where you must instantly recall normal lab values, ECG changes, and priority interventions under exam pressure, these techniques are lifesavers. Each anchor here uses encoding principles: the more bizarre, emotional, or sensory a memory, the harder it is to forget. Mnemonics compress complex lists into single triggers. Analogies connect abstract physiology to things you already know. Micro-stories activate your brain's narrative memory system. Use these anchors during your review, and when you see an NLE question, the cue will fire automatically — even under pressure.

Anchors

Topic

Electrolyte Normal Values

Concept

Normal serum sodium range: 135–145 mEq/L

Anchor Id

Difficulty

easy

Memory Aid

Think of a Filipino basketball jersey: number 13 to 145. The Philippine Basketball Association (PBA) has players numbered in that range. Sodium is the STAR player of ECF — it wears jerseys 135 to 145. Below 135 = the player is BENCHED (hyponatremia). Above 145 = the player got a RED CARD (hypernatremia).

Anchor Type

chunking

Why It Works

Associating numbers with a familiar cultural reference (PBA basketball) creates a vivid episodic memory peg for the sodium range.

Example Usage

Question asks: What is the normal sodium level? Trigger: PBA jersey → 135–145 mEq/L. Patient Na⁺ = 128 → below 135 → BENCHED = hyponatremia.

Recall Trigger

Think: 'PBA jersey numbers for sodium'

Topic

Electrolyte Normal Values

Concept

Normal serum potassium range: 3.5–5.0 mEq/L

Anchor Id

Difficulty

easy

Memory Aid

Potassium = K. Think 'K is for KAMOTE (sweet potato).' A kamote is 3.5 inches wide and 5 inches long. So potassium normal range = 3.5 to 5.0. BOTH are dangerous outside this range — eating too little kamote (hypokalemia) or force-feeding someone kamote until they burst (hyperkalemia) — BOTH can kill the heart.

Anchor Type

mnemonic

Why It Works

The kamote analogy ties the number range to a familiar Filipino food, and the exaggerated consequence (heart danger on both ends) reinforces the clinical significance.

Example Usage

Patient K⁺ = 6.2 — too much kamote = hyperkalemia → check for tall peaked T waves, prepare calcium gluconate.

Recall Trigger

Think: 'kamote — 3.5 to 5.0'

Topic

ABG Interpretation

Concept

ROME rule for ABG interpretation: Respiratory Opposite, Metabolic Equal

Anchor Id

Difficulty

medium

Memory Aid

ROME — like the ancient city of Rome. Imagine two Roman senators arguing: SENATOR RESPIRO (Respiratory) always does the OPPOSITE of what the emperor (pH) says. SENATOR METRO (Metabolic) always AGREES EQUALLY with the emperor. Respiratory Opposite = pH↑ then CO₂↓, or pH↓ then CO₂↑. Metabolic Equal = pH↑ then HCO₃↑, or pH↓ then HCO₃↓.

Anchor Type

acronym

Why It Works

ROME is a classic, proven acronym. The senator narrative adds narrative memory to reinforce the directional relationship, which is the most commonly confused part of ABG interpretation.

Example Usage

ABG: pH 7.28, CO₂ 58. pH is LOW (acidosis). CO₂ is HIGH. pH and CO₂ moved in OPPOSITE directions → Respiratory Acidosis.

Recall Trigger

Think: 'ROME — Respiratory Opposite, Metabolic Equal'

Topic

Potassium Imbalances

Concept

Hypokalemia ECG changes: Flattened T waves, ST depression, U waves

Anchor Id

Difficulty

medium

Memory Aid

Picture a FLAT TIRE (flattened T waves) on a car that got hit in a U-TURN (U waves), and the road has a DIP in it (ST depression). The car is LOW on gas (low potassium). So: LOW K = FLAT T, DIP in ST, and a U-TURN (U wave appears). Whenever you see U waves on an ECG in an NLE question — scream 'KAMOTE IS LOW!'

Anchor Type

visual_association

Why It Works

Visual association of a flat tire and U-turn creates a memorable scene that codes three distinct ECG findings simultaneously. The 'kamote' callback links it to A2.

Example Usage

ECG strip shows flattened T waves and prominent U waves → recall flat tire/U-turn → hypokalemia → check K⁺ level, do NOT give IV push KCl.

Recall Trigger

Think: 'flat tire, ST dip, U-turn' → hypokalemia ECG

Topic

Potassium Imbalances

Concept

Hyperkalemia ECG changes: Tall peaked T waves progressing to widened QRS and V-fib

Anchor Id

Difficulty

medium

Memory Aid

Picture a MOUNTAIN (tall peaked T waves) — it starts as a small anthill (early), then becomes MAYON VOLCANO (the widened QRS is the lava spreading out), and finally the volcano ERUPTS into chaos (ventricular fibrillation). HIGH K = HIGH MOUNTAIN T waves → spreading lava QRS → volcanic eruption V-fib. Think: 'Mayon Volcano = Hyperkalemia ECG progression.'

Anchor Type

visual_association

Why It Works

Mayon Volcano is a culturally iconic Filipino landmark. Using it as a progressive visual anchor (anthill → volcano → eruption) maps perfectly to the progression of hyperkalemia ECG changes.

Example Usage

ECG shows tall, tent-shaped T waves → Mayon starting to erupt → hyperkalemia → PRIORITY: give IV calcium gluconate to stabilize the myocardium.

Recall Trigger

Think: 'Mayon Volcano erupting' → hyperkalemia ECG progression

Topic

Potassium Imbalances - Nursing Priority

Concept

Never give potassium by IV push — max 10 mEq/hr on general unit, ensure urine output first

Anchor Id

Difficulty

medium

Memory Aid

Story: Nurse Ana was in a hurry and pushed 20 mEq KCl IV bolus to a dehydrated patient. The monitor went FLATLINE. She never worked again. The nurse beside her, Nurse Ben, always remembered the 3 rules of K: (1) NEVER push it IV — always drip slowly, (2) max 10 mEq per HOUR on the ward, (3) check IHI: 'Is He/She Inihaw (peeing)?' — make sure urine output is at least 30 mL/hr before giving. Nurse Ana's ghost haunts every nurse who forgets these 3 rules.

Anchor Type

micro_story

Why It Works

Emotionally charged micro-stories with consequences activate the brain's threat-detection system, making the rule almost impossible to forget. The 'IHI' Filipino food pun adds humor.

Example Usage

Question: The order is to infuse KCl 20 mEq IV. The nurse should: → recall ghost story → dilute and infuse slowly ≤10 mEq/hr, check urine output ≥30 mL/hr first.

Recall Trigger

Think: 'Nurse Ana's ghost — NEVER push K IV'

Topic

Calcium Imbalances

Concept

Chvostek's sign and Trousseau's sign indicate hypocalcemia (and hypomagnesemia)

Anchor Id

Difficulty

medium

Memory Aid

Chvostek = CHEEK/FACE twitch (tap the CHEEK = C for Chvostek = C for Cheek). Trousseau = TOURNIQUET/BP CUFF on arm causes carpal spasm (T for Tourniquet = T for Trousseau). Both signs = Ca²⁺ is TOO LOW. Memory: 'CHVOSTEK CHECKS the Cheek; TROUSSEAU TIES the arm.' If both signs are positive, the patient is 'CheekTie' positive = CALCIUM (and Magnesium) are LOW.

Anchor Type

mnemonic

Why It Works

Alliteration (Chvostek-Cheek, Trousseau-Tie) creates a phonetic link between the sign name and the body location, reducing confusion between the two commonly mixed-up signs.

Example Usage

Question describes a post-thyroidectomy patient with facial twitching when you tap near the ear → Chvostek (Cheek) → hypocalcemia → prepare IV calcium gluconate, institute seizure precautions.

Recall Trigger

Think: 'CheekTie positive = calcium low'

Topic

Potassium/Magnesium Imbalances

Concept

Calcium gluconate is the antidote for both hyperkalemia (cardiac membrane stabilization) AND hypermagnesemia

Anchor Id

Difficulty

hard

Memory Aid

Think of calcium gluconate as the BODYGUARD of the heart. When potassium is too high (hyperkalemia), the heart is being ATTACKED by potassium — the bodyguard (calcium gluconate) steps in front of the heart to SHIELD it, even though it does NOT remove the attacker (it doesn't lower K⁺). When magnesium is too high (hypermagnesemia), the breathing and reflexes slow down dangerously — the same bodyguard rescues the situation. One bodyguard, two dangerous situations.

Anchor Type

analogy

Why It Works

The bodyguard analogy clarifies the mechanism (membrane stabilization, not potassium removal) while also covering the dual use of calcium gluconate. This prevents the common exam error of thinking calcium gluconate lowers potassium.

Example Usage

K⁺ = 6.8, peaked T waves → cardiac emergency → FIRST give calcium gluconate (bodyguard) to stabilize heart → THEN shift K with insulin+dextrose → THEN remove with Kayexalate.

Recall Trigger

Think: 'Calcium gluconate = heart's bodyguard'

Topic

Magnesium Imbalances

Concept

Hypermagnesemia: Loss of deep tendon reflexes (DTRs) is an early warning sign

Anchor Id

Difficulty

medium

Memory Aid

Picture a PUPPET with strings (tendons/reflexes). When magnesium is NORMAL, the puppet dances beautifully. When magnesium is TOO HIGH, the strings go LIMP — the puppet collapses and can't move. HIGH Mg = LIMP puppet = LOST deep tendon reflexes. A nurse checking DTRs before giving MgSO₄ (as in preeclampsia management) is checking if the puppet's strings are still working. If the patellar reflex is absent = STOP the MgSO₄.

Anchor Type

visual_association

Why It Works

The puppet-with-limp-strings metaphor is visually dramatic and directly represents the physiologic mechanism (neuromuscular depression). It also ties to the critical clinical skill of DTR assessment in MgSO₄ therapy.

Example Usage

Patient on MgSO₄ tocolysis — nurse should check DTRs before each dose. If patellar reflex is absent → STOP infusion → recall limp puppet = Mg too high → give calcium gluconate (antidote).

Recall Trigger

Think: 'limp puppet = high magnesium = no DTRs'

Topic

Fluid Volume Imbalances

Concept

Fluid Volume Deficit (FVD) vs. Fluid Volume Excess (FVE) assessment findings

Anchor Id

A10

Difficulty

easy

Memory Aid

Think of a WATER JUG. FVD = the jug is EMPTY: flat neck veins (empty jug lying flat), dry mouth, no urine, rapid weak pulse, poor skin turgor. FVE = the jug is OVERFLOWING: distended neck veins (jug about to overflow), crackles in lungs (water pouring into the lungs), bounding pulse, edema (water spilling everywhere). The nursing priority for FVD = FILL THE JUG (IV fluids, isotonic). The nursing priority for FVE = DRAIN THE JUG (semi-Fowler's, diuretics, fluid restriction).

Anchor Type

analogy

Why It Works

The water jug is a concrete, everyday object that physically represents the clinical findings. The metaphor of filling vs. draining directly maps to the opposite nursing interventions.

Example Usage

Question: Patient has flat neck veins, dry mucous membranes, HR 118, BP 88/60 → empty jug = FVD → priority intervention: administer isotonic IV fluids (0.9% NaCl or LR) to restore circulating volume.

Recall Trigger

Think: 'empty jug vs. overflowing jug'

Topic

ABG Normal Values

Concept

Normal ABG values: pH 7.35–7.45, PaCO₂ 35–45, HCO₃⁻ 22–26, PaO₂ 80–100

Anchor Id

A11

Difficulty

easy

Memory Aid

Use the '7-35-45-22-26-80-100' number chain with this sentence: 'pH is SEVEN (7.35–7.45), CO₂ is THIRTY-FIVE to FORTY-FIVE, Bicarb is TWENTY-TWO to TWENTY-SIX, PaO₂ is EIGHTY to ONE HUNDRED.' Memory shortcut: pH has 7 in it (7.35–7.45). CO₂ = 35–45. Bicarb = 22–26 (think: 22 + 4 = 26). PaO₂ = 80–100. VISUAL: imagine a NORMAL PERSON running at 7.35–7.45 km/h, breathing CO₂ at 35–45 bpm, with a BICARB backpack weighing 22–26 kg, and blood oxygen shining at 80–100%.

Anchor Type

chunking

Why It Works

Chunking converts 8 separate numbers into 4 paired groups. The running person visualization creates a kinesthetic-visual memory for the interrelated ABG values.

Example Usage

ABG: pH 7.30, PaCO₂ 50, HCO₃⁻ 24. pH = LOW (acidosis). CO₂ = HIGH. HCO₃ = NORMAL. Using ROME: pH and CO₂ opposite = respiratory component. Diagnosis: Respiratory Acidosis, uncompensated.

Recall Trigger

Think: 'the normal running person' → 7/35-45/22-26/80-100

Topic

Sodium Imbalances

Concept

Correcting sodium disorders SLOWLY to prevent complications

Anchor Id

A12

Difficulty

hard

Memory Aid

Story: Mang Jose had severely low sodium (Na⁺ = 108). A new resident ordered rapid correction with hypertonic saline. Within 48 hours, Mang Jose couldn't talk, swallow, or move his face — he developed OSMOTIC DEMYELINATION (central pontine myelinolysis). His brain cells, like LPG ballooned suddenly then DEFLATED too fast, causing the myelin sheath to crack. RULE: Hyponatremia correction = MABAGAL (slow). Hypernatremia correction = also MABAGAL. Both ways — SLOW OR BRAIN GETS DAMAGED. Mang Jose's cautionary tale: 'Kapag mabilis ang correction, mabilis din ang destruction.'

Anchor Type

micro_story

Why It Works

The Filipino phrase at the end acts as a memorable rhyme-based rule. The LPG balloon analogy explains the pathophysiology of osmotic demyelination in a tangible way.

Example Usage

Question: Nurse correcting hyponatremia should: → recall Mang Jose → correct SLOWLY to prevent osmotic demyelination. Use isotonic or mildly hypertonic solutions, monitor sodium frequently.

Recall Trigger

Think: 'Mang Jose and the LPG balloon brain'

Topic

IV Fluid Tonicity

Concept

IV fluid tonicity: Isotonic expands ECF, Hypotonic hydrates cells, Hypertonic shrinks cells

Anchor Id

A13

Difficulty

medium

Memory Aid

Think of THREE types of IV bags as THREE types of Jollibee meals: ISOTONIC (0.9% NaCl, LR) = a REGULAR MEAL — everything stays in balance, you just get full (expands ECF without shifting fluid). HYPOTONIC (0.45% NaCl) = DRINKING TUBIG (water) — the water goes INSIDE your cells (moves water INTO cells, used for cellular dehydration and hypernatremia). HYPERTONIC (3% NaCl, D10W) = ASIN at its finest (super salty) — it pulls water OUT of your cells INTO the blood (used for severe hyponatremia, cerebral edema). Danger: too much HYPERTONIC = flood the lungs (pulmonary edema).

Anchor Type

analogy

Why It Works

The Jollibee/Filipino food analogies connect abstract osmolarity concepts to visceral, everyday sensory experiences. The 'asin' (salt) metaphor for hypertonic solutions is physiologically accurate and memorable.

Example Usage

Patient is hypernatremic with cellular dehydration → needs to hydrate the cells → 'tubig' (hypotonic) → 0.45% NaCl. BUT check: does patient have increased ICP? If yes, avoid hypotonic (will worsen cerebral edema).

Recall Trigger

Think: 'regular meal, tubig, asin' → isotonic, hypotonic, hypertonic

Topic

Metabolic Acidosis

Concept

Kussmaul respirations are a compensatory sign of metabolic acidosis

Anchor Id

A14

Difficulty

medium

Memory Aid

Kussmaul = 'Kusang SUMAL ang HININGA' (the breathing blows off deeply and rapidly on its own). In metabolic acidosis, HCO₃ is LOW, so the LUNGS step in and BLOW OFF CO₂ to compensate. Think: the body is trying to FAN AWAY the acid smell with fast, deep breaths. Kussmaul breathing = deep, labored, rapid breathing = the RESPIRATORY SYSTEM fanning away acid. Seen in DKA (diabetic ketoacidosis), which is the most common NLE scenario for metabolic acidosis.

Anchor Type

mnemonic

Why It Works

The Filipino phrase 'Kusang SUMAL' is a phonetic pun on 'Kussmaul' and captures the mechanism (blowing off CO₂) in the local language, creating a dual-language memory hook.

Example Usage

Patient with DKA has deep, rapid respirations → recall 'Kusang Sumal' → Kussmaul breathing → metabolic acidosis. ABG would show: pH↓, HCO₃↓, CO₂↓ (compensatory).

Recall Trigger

Think: 'Kusang Sumal ang Hininga' → Kussmaul breathing → metabolic acidosis

Topic

Fluid Volume Excess

Concept

Priority nursing action in fluid volume excess (FVE): Semi-Fowler's position for respiratory distress

Anchor Id

A15

Difficulty

easy

Memory Aid

Imagine a DROWNING PERSON in a swimming pool (the lungs are drowning in fluid). What's the FIRST thing you do? LIFT THEIR HEAD UP so they can breathe! That's exactly what semi-Fowler's or high-Fowler's position does — it lifts the patient up so fluid settles DOWN and away from the lungs. Using Maslow's hierarchy: AIRWAY and BREATHING are first. Even before diuretics, before fluid restriction — POSITION FIRST, BREATHE FIRST.

Anchor Type

analogy

Why It Works

The drowning analogy is visceral and triggers an instinctive understanding of why positioning is the priority before any pharmacologic intervention. It reinforces Maslow's hierarchy of physiologic needs.

Example Usage

Patient with heart failure develops crackles and dyspnea → FIRST ACTION: position in high-Fowler's (lift the head) → THEN administer oxygen → THEN give furosemide as ordered.

Recall Trigger

Think: 'drowning person — lift the head first' → semi-Fowler's is priority in FVE with dyspnea

Topic

Acid-Base Imbalances

Concept

Causes of metabolic alkalosis: Vomiting, NGT suction, excess antacids, diuretics

Anchor Id

A16

Difficulty

medium

Memory Aid

Metabolic Alkalosis causes = VNAD (pronounced 'wunaaaad!' — like a Filipino exclaiming in disbelief): V = Vomiting, N = NGT suction (Nasogastric), A = Antacids (excessive), D = Diuretics (loop/thiazide). 'VNAD!' — you'd say 'wunaaad!' in surprise when you see HCO₃ sky-high and the patient has been vomiting for days. All of VNAD causes LOSS OF ACID or EXCESS BASE — so pH and HCO₃ both go UP (Metabolic EQUAL, per ROME).

Anchor Type

acronym

Why It Works

The acronym VNAD doubled as a Filipino exclamatory expression creates an auditory-emotional cue. It also reinforces the ROME rule application for metabolic alkalosis.

Example Usage

Patient on prolonged NGT suction, ABG: pH 7.51, HCO₃ 32 → VNAD causes → metabolic alkalosis → pH↑ and HCO₃↑ (equal) = metabolic per ROME.

Recall Trigger

Think: 'VNAD!' → metabolic alkalosis causes

Topic

Sodium Imbalances

Concept

Hyponatremia manifestations are primarily NEUROLOGIC due to cerebral cell swelling

Anchor Id

A17

Difficulty

medium

Memory Aid

Picture your BRAIN as a SPONGE inside a HARD SKULL. When sodium is LOW, water rushes INTO brain cells (osmosis — like pouring water on the sponge). The sponge SWELLS, but the skull doesn't expand — so the brain gets SQUEEZED. Result: headache, confusion, seizures, coma. The skull is the limiting factor. RULE: LOW SODIUM = BRAIN SPONGE SWELLS = NEURO SYMPTOMS. This is why you fix it SLOWLY — deflate the sponge gradually or it tears.

Anchor Type

analogy

Why It Works

The brain-as-sponge-inside-a-skull metaphor directly models increased intracranial pressure in hyponatremia, making the pathophysiology and clinical manifestations logically connected and memorable.

Example Usage

Na⁺ = 115, patient is confused and having seizures → swollen brain sponge → hyponatremia → priority: seizure precautions, slow IV correction with 0.9% NaCl or cautious hypertonic saline.

Recall Trigger

Think: 'swollen sponge in a hard skull' → hyponatremia → neurologic symptoms

Topic

Potassium Imbalances

Concept

Management of hyperkalemia: Sequential steps — Calcium gluconate → Insulin+Dextrose → Kayexalate/Dialysis

Anchor Id

A18

Difficulty

hard

Memory Aid

Story: There's a FIRE in the house (K⁺ dangerously high, heart in danger). Step 1: CALL THE FIREGUARD to protect the house (Calcium gluconate — stabilizes cardiac membrane, protects the heart — does NOT put out the fire). Step 2: SWEEP THE FIRE into a container (Insulin + Dextrose — shifts K⁺ INTO cells, temporarily removes it from circulation). Step 3: THROW THE CONTAINER OUT THE DOOR (Kayexalate — removes K⁺ from the body via GI tract; or Dialysis for renal failure patients). THREE STEPS: GUARD → SWEEP → THROW OUT.

Anchor Type

micro_story

Why It Works

The firefighting metaphor maps the sequential logic of hyperkalemia management with an action-based narrative that distinguishes membrane stabilization (does not lower K) from actual potassium removal.

Example Usage

K⁺ = 7.0, wide QRS on ECG, patient in renal failure → FIRE: 1. Calcium gluconate IV (Guard — protect heart) → 2. Insulin + D50W (Sweep — shift K into cells) → 3. Hemodialysis (Throw Out — remove K from body).

Recall Trigger

Think: 'house fire — Guard, Sweep, Throw Out'

Topic

Fluid Balance Monitoring

Concept

Daily weight monitoring: 1 kg weight change ≈ 1 liter of fluid

Anchor Id

A19

Difficulty

easy

Memory Aid

RHYME: 'One kilo a day, one liter they say — weigh at the same time, or the numbers won't rhyme. If the kilo goes up, the fluid's gone up; if the kilo goes down, the fluid's gone down.' Applied: In FVE (heart failure, CKD) — gaining 1–2 kg overnight = 1–2 liters of fluid retention = RED FLAG. In FVD — losing 1 kg/day = losing 1 liter = dehydration. USE: same time, same clothes, same scale, same day.

Anchor Type

rhyme

Why It Works

The rhyme creates phonological encoding, and the equal-sign relationship (1 kg = 1 L) is embedded in the rhythm. The same-time-same-clothes rule prevents common clinical errors.

Example Usage

Patient with heart failure gains 2.5 kg overnight → recall rhyme → approximately 2.5 L fluid retention → notify physician, assess for respiratory distress, check for worsening edema.

Recall Trigger

Think: 'One kilo, one liter' rhyme

Topic

Calcium Imbalances

Concept

Hypocalcemia: Priority nursing concern is AIRWAY (laryngospasm risk)

Anchor Id

A20

Difficulty

hard

Memory Aid

In hypocalcemia, the muscles are HYPERIRRITABLE — they can spasm anywhere. The DEADLIEST spasm is the LARYNX (throat muscles closing shut = laryngospasm = no airway). Remember: 'When CA is LOW, the THROAT can GO.' Nursing priority = AIRWAY first (Maslow). Keep IV calcium gluconate at bedside. Keep emergency tracheostomy tray available. Institute seizure and fall precautions. This is especially important for post-THYROIDECTOMY and post-PARATHYROIDECTOMY patients.

Anchor Type

mnemonic

Why It Works

The rhyme 'When CA is LOW, the THROAT can GO' directly links the electrolyte imbalance to the highest-priority airway complication, reinforcing Maslow-based prioritization.

Example Usage

Post-thyroidectomy patient develops tingling lips and positive Chvostek's sign → hypocalcemia → PRIORITY: assess airway, prepare IV calcium gluconate, have emergency airway equipment at bedside.

Recall Trigger

Think: 'When CA is LOW, the THROAT can GO' → airway priority in hypocalcemia

Revision Game

Potassium (K⁺)

Clue

I am the electrolyte that loves the inside of your cells. When I am low, your heart and muscles throw a weak tantrum. If I am given by IV push, I will stop the heart immediately. Who am I?

Memory Link

A2 (kamote) and A6 (Nurse Ana's ghost story) — potassium is kamote, and you NEVER push it IV.

Calcium gluconate

Clue

I am the guardian of the heart. I do NOT lower potassium, and I am also the antidote for too much magnesium. I stabilize membranes and am your first action in a potassium emergency. What am I?

Memory Link

A8 (bodyguard analogy) — one bodyguard, two emergencies: hyperkalemia and hypermagnesemia.

Trousseau's sign (BP cuff → carpal spasm) and Chvostek's sign (tap cheek → facial twitch); both indicate hypocalcemia AND hypomagnesemia

Clue

Two clinical signs both point to the same two electrolyte deficiencies. One is tested by inflating a blood pressure cuff; the other by tapping the face near the ear. Name both signs and both electrolyte deficiencies.

Memory Link

A7 (CheekTie mnemonic) — Chvostek checks the Cheek; Trousseau Ties the arm.

Respiratory Acidosis; most common cause is hypoventilation from COPD, oversedation, or respiratory failure

Clue

I am an ABG pattern: pH is low, CO₂ is high. The senators are disagreeing. What acid-base disorder is this, and what is the most common Philippine clinical cause?

Memory Link

A3 (ROME) — Respiratory Opposite: pH LOW, CO₂ HIGH = moving in opposite directions = respiratory cause, and pH is low = acidosis.

Metabolic Alkalosis; V in VNAD = Vomiting. pH and HCO₃ both HIGH = Metabolic EQUAL per ROME.

Clue

I am a patient who has been vomiting for 3 days. My ABG shows pH 7.52 and HCO₃ of 35. What disorder do I have, and which VNAD cause applies to me?

Memory Link

A16 (VNAD mnemonic) — V is for vomiting → metabolic alkalosis.

Priority: Assess airway immediately, have IV calcium gluconate at bedside, prepare emergency airway equipment. Complication being prevented: laryngospasm from hypocalcemia.

Clue

A patient is post-thyroidectomy and suddenly develops stridor, difficulty swallowing, and a positive Chvostek's sign. What is the priority nursing action, and what complication are you preventing?

Memory Link

A20 (When CA is LOW, the THROAT can GO) and A7 (CheekTie) — post-thyroidectomy = hypocalcemia risk = airway priority.

Fluid Volume Excess (FVE/Hypervolemia). First nursing action: Position in semi-Fowler's or high-Fowler's to relieve respiratory distress.

Clue

A patient with chronic kidney disease gains 2 kg overnight. He has crackles in both lung bases and distended neck veins. What is his diagnosis and what is the VERY FIRST nursing action?

Memory Link

A10 (overflowing jug) and A15 (drowning person — lift the head first) — overflowing jug signs present, Maslow's airway/breathing priority = position first.

Metabolic Acidosis; the breathing pattern is called Kussmaul respirations (deep, rapid, labored breaths to blow off CO₂ and compensate for the low HCO₃).

Clue

I cause deep, labored, rapid breathing as a compensatory response. I am associated with DKA and renal failure. My breathing pattern has a special name. What is my acid-base disorder and what is my breathing pattern called?

Memory Link

A14 (Kusang Sumal ang Hininga) — Kussmaul breathing blows off CO₂ to compensate for metabolic acidosis from MUDPILES causes.

30 mL/hr = minimum acceptable urine output for an adult, indicating adequate renal function. 0.5 mL/kg/hr = weight-based alternative. If output is less than this, potassium must be withheld and the physician notified.

M — Methanol toxicity
U — Uremia (renal failure)
D — Diabetic ketoacidosis (DKA)
P — Paraldehyde
I — Isoniazid/Iron overdose
L — Lactic acidosis (shock, sepsis)
E — Ethylene glycol
S — Salicylate (aspirin) toxicity
