,Master Guide Overview
Medical-Surgical nursing forms the structural backbone of acute adult nursing practice. A rigorous mastery of
physiological mechanisms, pathophysiological alterations, pharmacological interventions, and nursing prioritization is
required to deliver safe, evidence-based care and succeed on the NCLEX-RN examination.
CLINICAL PRIORITIZATION FRAMEWORK (ABCDE & MASLOW)
When evaluating clinical management and NCLEX-style questions, always prioritize interventions based on:
1. Airway: Patency, obstruction, cervical spine protection.
2. Breathing: Spontaneous ventilation, oxygenation, work of breathing.
3. Circulation: Perfusion, blood pressure, cardiac output, hemorrhage control.
4. Disability: Neurological status, GCS, pupillary response.
5. Exposure/Environment: Hypothermia, trauma assessment, rash/burn inspection.

, SECTION 1: HIGH-YIELD SYSTEM REVIEWS
1. Cardiovascular Nursing Core Review
Coronary Artery Disease (CAD) & Myocardial Infarction (MI): MI occurs when ischemia causes irreversible cellular
necrosis. STEMI involves full-thickness transmural ischemia (ST elevation in 2 consecutive leads), whereas NSTEMI
involves partial-thickness subendocardial ischemia (elevated Troponin I/T without ST elevation).
• Immediate MI Interventions (MONA / BOMA): Oxygen (if SpO2 < 90%), Nitroglycerin SL (0.4 mg q5min x 3 doses;
absolute contraindication with phosphodiesterase-5 inhibitors), Aspirin (162-325 mg chewed), Morphine IV for
refractory pain, Beta-blockers within 24h.
• Cardiac Markers: Troponin I (<0.03 ng/mL normal, rises 2-4h, peaks 12-24h, stays elevated 7-10 days); Creatine
Kinase-MB (CK-MB rises 3-6h, peaks 12-24h, returns to normal in 48-72h).
• Heart Failure (HF): Left-sided HF leads to pulmonary congestion (dyspnea, orthopnea, crackles, cough with pink
frothy sputum). Right-sided HF leads to systemic venous congestion (JVD, peripheral edema, hepatomegaly, ascites).
• Medications: ACE inhibitors ("-pril") lower mortality by preventing ventricular remodeling; monitor K+ and dry cough.
Furosemide (Loop diuretic) causes hypokalemia, ototoxicity. Digoxin increases inotropy and decreases chronotropy;
therapeutic level 0.5-2.0 ng/mL (toxicity signs: nausea, visual halos, bradycardia).
2. Respiratory Nursing Core Review
Arterial Blood Gas (ABG) Interpretation: Normal values: pH 7.35-7.45, PaCO2 35-45 mmHg, HCO3 22-26 mEq/L,
PaO2 80-100 mmHg.
• Respiratory Acidosis: pH < 7.35, PaCO2 > 45 (Hypoventilation, COPD, Opioid overdose).
• Respiratory Alkalosis: pH > 7.45, PaCO2 < 35 (Hyperventilation, Anxiety, Early Pulmonary Embolism).
• Metabolic Acidosis: pH < 7.35, HCO3 < 22 (DKA, Renal failure, Diarrhea, Severe Shock).
• Metabolic Alkalosis: pH > 7.45, HCO3 > 26 (Severe vomiting, Nasogastric suctioning, Excess antacids).
Chest Tube Management: Water seal chamber must fluctuate (tidaling) with respiration; continuous bubbling indicates
an air leak. Collection chamber monitored hourly. Suction control chamber typically set at -20 cmH2O. If chest tube
dislodges from patient: cover insertion site with sterile occlusive dressing taped on 3 sides to prevent tension
pneumothorax. If tubing disconnects from unit: submerge distal end in 2-4 cm of sterile saline.
3. Neurological Nursing Core Review
Increased Intracranial Pressure (ICP): Normal ICP is 5-15 mmHg. Sustained ICP > 20 mmHg requires intervention.
• Cushing's Triad (Late sign of impending herniation): 1. Severe Hypertension with widening pulse pressure; 2.
Bradycardia; 3. Irregular, shallow respirations (Cheyne-Stokes).
• Interventions for High ICP: Elevate HOB 30 degrees, maintain neck in neutral alignment, avoid hyperflexion/hip
flexion, administer Mannitol (osmotic diuretic) or Hypertonic Saline (3%), hyperventilate temporarily if ordered, prevent
shivering/coughing, avoid cluster care to prevent ICP spikes.
• Stroke Management: Ischemic stroke (87%): Ischemic window for IV tPA (Alteplase) is within 3 to 4.5 hours of
symptom onset. Exclusions: Active hemorrhage, BP > 185/110 mmHg, recent surgery, INR > 1.7. Hemorrhagic stroke:
Maintain strict BP control, avoid anticoagulants/thrombolytics, prepare for surgical clipping/coiling.
4. Gastrointestinal & Hepatic Nursing Core Review
Hepatic Cirrhosis & Portal Hypertension: Complications include Ascites, Esophageal Varices, Hepatic
Encephalopathy, and Jaundice.
• Hepatic Encephalopathy: Caused by accumulation of toxic ammonia levels in blood crossing BBB. Manifestations:
Asterixis (flapping tremor), confusion, fetor hepaticus. Treatment: Lactulose (promotes ammonia excretion via stool,
aim for 2-3 soft stools/day) and Neomycin/Rifaximin (reduces ammonia-producing gut bacteria).
Medical-Surgical Nursing Review Guide Page 3 of 61
, • Esophageal Varices: Medical emergency if bleeding occurs. Priorities: Airway protection, IV access, Octreotide
infusion, Vasopressin, endoscopic band ligation, or Blakemore tube tamponade.
• Acute Pancreatitis: Autodigestion of pancreas by digestive enzymes. Presentation: Severe epigastric pain radiating
to back, relieved by leaning forward. Elevated Serum Amylase and Lipase (Lipase is most specific). Sign: Grey
Turner's sign (flank ecchymosis), Cullen's sign (periumbilical ecchymosis). Interventions: NPO, IV fluid resuscitation,
pain control (Hydromorphone/Morphine), enteral nutrition via NJ tube if prolonged.
5. Renal, Fluid & Electrolyte Nursing Core Review

antidote.
6. Endocrine System Core Review
Diabetic Ketoacidosis (DKA) vs. Hyperglycemic Hyperosmolar State (HHS):
• DKA: Type 1 DM, rapid onset, BG > 250 mg/dL, positive serum/urine ketones, Metabolic Acidosis (pH < 7.30, HCO3 <
18), Kussmaul respirations, fruity breath odor. Treatment: 0.9% Normal Saline fluid replacement, regular IV insulin drip
(0.1 units/kg/hr), monitor K+ closely (add K+ to IV fluids when K+ drops below 5.0 mEq/L to prevent hypokalemia),
add Dextrose 5% when BG drops to 200-250 mg/dL to prevent cerebral edema.
• HHS: Type 2 DM, gradual onset, BG > 600 mg/dL, negative/trace ketones, normal pH (>7.30), severe dehydration and
hyperosmolality. Treatment: Massive IV fluid rehydration prior to or concurrent with low-dose insulin infusion.
7. Musculoskeletal & Burns Core Review
Compartment Syndrome: Increased tissue pressure within a confined fascial space compromising circulation.
Emergency requiring immediate decompression (Fasciotomy).
• 6 Ps: Pain (out of proportion to injury, unrelieved by opioids - earliest sign), Paresthesia, Pallor, Pressure, Paralysis,
Pulselessness (late sign). Nursing Priority: Elevate limb NO HIGHER than heart level, remove restrictive dressings/
casts, notify surgeon immediately. Do NOT apply ice or heat.
Burn Injury Management & Parkland Formula:
• Rule of Nines: Head (9%), Entire Arm (9% each = 18% total), Anterior Trunk (18%), Posterior Trunk (18%), Entire
Leg (18% each = 36% total), Perineum (1%).
• Parkland Formula: Total 24-hour Lactated Ringer's volume = 4 mL x Body Weight (kg) x % Total Body Surface
Area (%TBSA) burned. Give 1/2 of total calculated volume over the first 8 hours (from time of burn injury), and
remaining 1/2 over the next 16 hours. Target urine output: 0.5 to 1.0 mL/kg/hr (30-50 mL/hr).
