Cancer Warning Signs
CAUTION UP
Change · A lesion · Unusual bleeding · Thickening · Indigestion · Obvious skin changes · Nagging cough · Unexplained weight loss · Pernicious anemia
Early cancer warning signs — early detection saves lives
CAUTION UP helps nurses remember the key indicators of cancer. Early detection dramatically improves treatment outcomes — knowing these signs helps you advocate for your patients before symptoms worsen.
C
Change in bowel or bladder habits
A
A lesion or sore that will not heal
U
Unusual bleeding or discharge
T
Thickening or lump in breast or tissue
I
Indigestion or difficulty swallowing
O
Obvious change in wart or mole
N
Nagging cough or hoarseness
U
Unexplained weight loss or loss of appetite
P
Pernicious anemia — B12 deficiency
Heart Failure
Left-sided HF: pulmonary symptoms (SOB, crackles, pink frothy sputum). Right-sided HF: systemic edema (JVD, pitting edema, weight gain).
Heart Failure — Left vs Right
Telling left from right heart failure: lungs vs body — the most testable distinction
Left-sided HF (most common): left ventricle fails → blood backs up into pulmonary circulation. Signs: dyspnea (especially at rest or lying flat — orthopnea), paroxysmal nocturnal dyspnea, crackles in lungs, pink frothy sputum (severe), decreased SpO2, S3 gallop. Right-sided HF: right ventricle fails → backs up into systemic circulation. Signs: JVD (jugular vein distension), dependent pitting edema (ankles, sacrum), hepatomegaly, ascites, weight gain. Both: fatigue, decreased activity tolerance. Management: daily weights (report >2 lb gain in 1 day or >5 lb in 1 week), fluid restriction, low-sodium diet, elevate HOB, oxygen.

Coronary Arteries
RIGHT CAMP LEFT AC
Right Coronary Artery · Marginal Artery · Posterior Intraventricular · Left Anterior Descending · Circumflex Artery
I have a RIGHT to CAMP if you LEFT off the AC

A
Posterior intraventricular artery
M
Left coronary artery (main)
P
Anterior descending artery (LAD — widowmaker)

Heart Murmurs
hARD ASS MRS. MSD
Aortic Regurg=Diastolic · Aortic Stenosis=Systolic · Mitral Regurg=Systolic · Mitral Stenosis=Diastolic
Remember which phase you hear each heart murmur
Heart murmurs occur when turbulent blood flow creates abnormal sounds. Knowing which phase (systolic vs diastolic) a murmur occurs in is critical for identifying the underlying valve problem on NCLEX and in clinical practice.
hARD
Aortic Regurgitation = Diastolic murmur
ASS
Aortic Stenosis = Systolic murmur
MRS.
Mitral Regurgitation = Systolic murmur
MSD
Mitral Stenosis = Diastolic murmur
Cardiac Valves
Toilet Paper My Ass
Tricuspid · Pulmonic · Mitral · Aortic

Blood flows through the heart valves in a specific sequence. Remembering this order is essential for understanding cardiac physiology, heart sounds, and valve disorders. The sequence follows blood from the right side to the left side of the heart.
T
Tricuspid — right atrium to right ventricle
P
Pulmonic — right ventricle to pulmonary artery
M
Mitral — left atrium to left ventricle
A
Aortic — left ventricle to aorta and body

Hypercalcemia
GROANS MOANS BONES STONES OVERTONES
Constipation · Joint pain · Bone loss · Kidney stones · Psychiatric symptoms
Signs and symptoms of hypercalcemia — the rhymes make it stick
Hypercalcemia occurs when calcium levels exceed 10.5 mg/dL. Common causes: hyperparathyroidism, malignancy, prolonged immobility, excess vitamin D. The rhyming words make these symptoms impossible to forget — and they're high yield for NCLEX.
GROANS

OVERTONES
Psychiatric — confusion, depression, psychosis
Addison's Disease
STEROID
Sugar/Sodium low · Tired/muscle weakness · Electrolyte imbalance · Reproductive change · lOw BP · Increased pigmentation · Diarrhea/Depression
Assessment findings of Addison's Disease — low adrenal hormones
Addison's Disease is caused by LOW secretion of adrenal hormones — glucocorticoids, mineralocorticoids, and androgens. The body lacks the hormones it needs to maintain blood pressure, blood sugar, and electrolyte balance. Addisonian crisis is a life-threatening emergency.

MI — MONA
MI treatment: MONA — Morphine, Oxygen, Nitrates, Aspirin. 12-lead ECG within 10 min. Troponin is gold standard.
Myocardial Infarction
Recognizing and responding to MI — time is muscle, every minute counts
Classic MI symptoms: crushing chest pain (may radiate to jaw, left arm, back), diaphoresis, nausea, shortness of breath. Women/diabetics: atypical — jaw pain, fatigue, nausea only. MONA: Morphine (reduces preload/pain — now questioned in STEMI), Oxygen (if SpO2 <90%), Nitrates (vasodilation — hold if systolic <90 or recent sildenafil use), Aspirin (antiplatelet — 325 mg chewed). ECG: within 10 minutes of arrival. ST elevation = STEMI — needs cath lab within 90 min. Troponin: gold standard biomarker, rises 3–4 hr after MI. Give nothing by mouth (NPO) — may need procedure.
M
Morphine — pain/anxiety
O
Oxygen — if SpO2 <90%
N
Nitrates — vasodilate, hold if BP low
A
Aspirin 325 mg chewed
Stroke — FAST
Stroke: FAST — Face drooping, Arm weakness, Speech difficulty, Time to call 911. tPA within 3–4.5 hours of onset.
Stroke Recognition and Care
Time-critical emergency — recognizing stroke and the nursing response
FAST: Face drooping (ask to smile — asymmetry), Arm weakness (raise both arms — one drifts down), Speech difficulty (slurred or unable to speak), Time — call 911 immediately. Two types: Ischemic (87% — clot) and Hemorrhagic (13% — bleed). Treatment: Ischemic → tPA (alteplase) if within 3–4.5 hours of LAST KNOWN WELL, no hemorrhage on CT. Hemorrhagic → no tPA, manage BP, possible surgery. Nursing: NIH Stroke Scale assessment, position HOB 30°, NPO until swallow evaluation, falls precautions, BP management (allow permissive hypertension in ischemic unless giving tPA). Time is brain — 1.9 million neurons lost per minute.
F
Face drooping
A
Arm weakness
S
Speech difficulty
T
Time — call 911 now
tPA window
3–4.5 hours from last known well
Increased Intracranial Pressure
ICP signs: Cushing's Triad — Bradycardia, Hypertension (widening pulse pressure), Irregular respirations. LATE sign = impending herniation.
Increased ICP
Cushing's Triad is a medical emergency — the nurse must recognize it and act immediately
Normal ICP: 5–15 mmHg. Early ICP signs: headache (worse with straining), nausea/vomiting (projectile), altered LOC, pupil changes (unequal, sluggish). Late sign — Cushing's Triad (EMERGENCY): Bradycardia + Hypertension (widening pulse pressure) + Irregular/slow respirations → impending brainstem herniation. Nursing: HOB 30°, head midline (no neck rotation — impairs venous drainage), avoid clustering care, dim lights/quiet environment, avoid Valsalva (no straining), monitor pupil response. Do NOT: suction vigorously, hip flexion >90°, prone positioning.
Early
Headache, N/V, altered LOC
Cushing's Triad
Bradycardia + HTN + irregular RR
Position
HOB 30°, head midline
Avoid
Straining, Valsalva, clustering care
Respiratory — COPD vs Asthma
COPD: chronic, progressive, barrel chest, pursed-lip breathing. Asthma: episodic, reversible, wheezing, triggered. O2 cautiously in COPD.
COPD vs Asthma
Two obstructive lung diseases with important differences — NCLEX loves the oxygen question in COPD
COPD (emphysema + chronic bronchitis): irreversible airway obstruction. Emphysema: barrel chest, pursed-lip breathing, decreased breath sounds, 'pink puffer' (fights to breathe). Chronic bronchitis: productive cough >3 months/2 years, 'blue bloater.' O2 in COPD: hypoxic drive — give O2 2–3 L/NC, target SpO2 88–92% (not 95–100%). High O2 may suppress respiratory drive. Asthma: reversible bronchospasm, triggered (allergens, exercise, cold). Wheezing on expiration. Peak flow meter: green >80%, yellow 50–80%, red <50%. Rescue inhaler (albuterol) before preventive (corticosteroid inhaler).
COPD O2
2–3 L, target SpO2 88–92%
Emphysema
Barrel chest, pursed lips, pink puffer
Chronic Bronchitis
Productive cough, blue bloater
Asthma
Reversible, wheezing, rescue before preventive
Pneumonia
Pneumonia assessment: fever, productive cough, crackles, decreased breath sounds. Position: semi-Fowler's. Encourage fluids and deep breathing.
Pneumonia Nursing
The most common hospital-acquired infection — assessment, positioning, and prevention
Signs: fever and chills, productive cough (yellow/green/rust-colored sputum), pleuritic chest pain (worse with breathing), crackles and decreased breath sounds in affected lobe, tachypnea, hypoxia. Community-acquired (CAP): S. pneumoniae most common. Hospital-acquired (HAP): gram-negative organisms, MRSA. Nursing care: semi-Fowler's position (HOB 30–45°), encourage fluids (2–3 L/day unless restricted — thins secretions), deep breathing and coughing exercises, incentive spirometer, turn every 2 hours, ambulate early. Prevention: pneumococcal vaccine, hand hygiene, oral care in ventilated patients (VAP bundle).
Diabetes — Hypo vs Hyperglycemia
Hypoglycemia (<70): Cold and Clammy = give candy. Hyperglycemia (>180): Hot and Dry = sugar high.
Hypoglycemia vs Hyperglycemia
The quick way to distinguish and treat two dangerous blood sugar extremes
Hypoglycemia (<70 mg/dL): Cold and Clammy — diaphoresis, tremors, tachycardia, confusion, seizure. Cause: too much insulin, missed meal, excess exercise. Treatment: 15-15 rule — 15g fast carbs (4 oz juice, glucose tablets), recheck in 15 min. If unconscious: IV dextrose (D50) or glucagon IM. Hyperglycemia (>180–250): Hot and Dry — polyuria (3 Ps: Polyuria, Polydipsia, Polyphagia), fruity breath (DKA), Kussmaul respirations (deep, rapid — blowing off CO2 in DKA). DKA (Type 1): ketones, pH <7.3. HHS (Type 2): extreme hyperglycemia, no ketones, elderly. Treatment: insulin drip, IV fluids, K+ replacement.
Hypo <70
Cold/clammy, diaphoresis, tremor, confusion
Hypo Tx
15g carbs → recheck 15 min, or IV D50
Hyper
Hot/dry, 3 Ps, fruity breath
DKA

Renal Failure — AEIOU
AEIOU — Acute kidney injury complications: Acidosis, Electrolyte imbalances (K+↑), Intoxication (uremia), Overload (fluid), Uremia.
Acute Kidney Injury
Recognizing and managing AKI — the NCLEX expects nurses to monitor and intervene
AKI: rapid decline in kidney function over hours to days. Stages (RIFLE/KDIGO): Risk, Injury, Failure, Loss, ESKD. Oliguric phase: urine output <0.5 mL/kg/hr, BUN and creatinine rise, K+ rises (hyperkalemia — most dangerous). AEIOU complications: Acidosis (metabolic), Electrolyte imbalance (hyperkalemia → EKG changes, peaked T-waves → cardiac arrest), Intoxication (uremia — confusion, asterixis), Overload (fluid), Uremia (N/V, pericarditis, pruritus). Nursing: strict I&O, daily weights, low K+ diet, BP monitoring, dialysis access care. Fluid challenge: 500 mL NS bolus if pre-renal cause.
A
Acidosis — metabolic
E
Electrolytes — hyperkalemia, peaked T waves
I
Intoxication — uremia, confusion
O
Overload — fluid
U
Uremia — N/V, pericarditis, pruritus
Postoperative Care
Post-op ABCDE: Airway, Breathing, Circulation, Drugs (anesthesia), Everything else (pain, N/V, wound).
Postoperative Nursing
Systematic assessment immediately after surgery — and the complications to watch for
Immediate post-op (PACU): Airway — maintain, suction if needed. Breathing — respiratory rate, SpO2, breath sounds. Circulation — BP, HR, bleeding at surgical site. Drugs — anesthesia reversal, pain management. Temperature — hypothermia common (warm blankets, forced air). Early complications: respiratory depression (opioids — give Narcan), airway obstruction (tongue, secretions), hemorrhage (increasing HR, decreasing BP), emergence delirium. Late complications: atelectasis (encourage deep breathing, IS), DVT (SCDs, early ambulation, anticoagulants), wound infection (3–5 days post-op fever), paralytic ileus (listen for bowel sounds).
Fluid and Electrolytes — Big 5
Hypokalemia: U waves, weak muscles. Hyperkalemia: peaked T waves. Hyponatremia: confusion, seizures. Hypernatremia: thirst, dry mucosa.
Electrolyte Imbalances
The five electrolytes NCLEX tests most — know the critical values and EKG changes
Potassium (normal 3.5–5.0): Hypo (<3.5): muscle weakness, cramps, U waves on EKG, constipation. Causes: diuretics, vomiting, NG suction. Replace slowly (never IV push — fatal). Hyper (>5.5): peaked T waves, wide QRS, muscle weakness, cardiac arrest. Treat: calcium gluconate (protect heart), insulin+dextrose (shift K+ into cells), Kayexalate. Sodium (normal 135–145): Hypo (<135): headache, confusion, seizures — restrict fluids, hypertonic saline (slowly or central herniation). Hyper (>145): thirst, dry mucosa, restlessness, seizures — free water replacement. Calcium: Hypo — Trousseau's and Chvostek's signs, tetany. Magnesium: Hypo — cardiac dysrhythmias.
Hypokalemia
U waves, muscle weak — diuretics cause
Hyperkalemia
Peaked T waves — cardiac emergency
Hyponatremia
Confusion, seizures — fluid restrict
Hypernatremia
Thirst, dry — give free water slowly
Wound Care and Pressure Injuries
Pressure injury stages: I (redness), II (partial thickness), III (full thickness), IV (bone/tendon visible). Turn every 2 hours.
Pressure Injuries
Staging wounds and preventing pressure injuries — prevention is always better than treatment
Stage I: intact skin, non-blanchable redness. Intervention: relieve pressure, moisturize. Stage II: partial thickness skin loss — shallow open ulcer or blister. Stage III: full thickness skin loss, subcutaneous tissue visible, no bone/tendon. Stage IV: full thickness, bone/tendon/muscle exposed. Unstageable: covered by eschar — cannot stage until debrided. Deep tissue injury (DTI): purple/maroon discoloration, intact skin. Prevention: turn every 2 hours, pressure-relieving mattress, keep dry (moisture = skin breakdown), adequate nutrition (protein + vitamin C + zinc), assess Braden scale. Never massage over bony prominences — increases breakdown.
Stage I
Non-blanchable redness — intact skin
Stage II
Blister or shallow ulcer
Stage III
Full thickness — no bone visible
Stage IV
Bone/tendon visible
Prevention
Turn q2h, Braden scale, nutrition
ABG Interpretation
ABGs: pH 7.35–7.45, PaCO2 35–45, HCO3 22–26. ROME: Respiratory Opposite, Metabolic Equal.
ABG Interpretation
The step-by-step method for reading arterial blood gases — ROME makes it systematic
Normal values: pH 7.35–7.45, PaCO2 35–45 mmHg (respiratory), HCO3 22–26 mEq/L (metabolic). Step 1: pH — acidosis (<7.35) or alkalosis (>7.45)? Step 2: PaCO2 — if it matches pH direction (opposite), it's respiratory. Step 3: HCO3 — if it matches pH direction (same), it's metabolic. ROME: Respiratory Opposite (pH up, CO2 down = alkalosis), Metabolic Equal (pH up, HCO3 up = alkalosis). Compensation: the system NOT causing the problem tries to correct pH. Respiratory acidosis (hypoventilation, COPD): pH↓, CO2↑. Metabolic acidosis (DKA, renal failure): pH↓, HCO3↓. Metabolic alkalosis (vomiting, NG suction): pH↑, HCO3↑.
