Top High-Yield CCS Cases Breakdown

Case Prototype 1: Acute Appendicitis in Young Adult

Clinical Setup

  • Presentation: 22-year-old male with 12 hours of periumbilical pain shifting to the Right Lower Quadrant (RLQ), nausea, low-grade fever (38.1°C / 100.6°F).

Optimal Order Pathway

  1. Immediate Orders (Minute 0–1):
    • Pulse oximetry, continuous cardiac monitoring, BP q15min.
    • IV access, Normal saline 0.9% IV @ 150 mL/hr.
    • NPO status stat.
  2. Focused Exam (Minute 1–2):
    • Abdomen exam (Reveals McBurney’s point tenderness, Rovsing sign, rebound/guarding).
  3. Diagnostics (Minute 2–4):
    • CBC with differential (leukocytosis with left shift).
    • BMP, Urinalysis (rules out nephrolithiasis/UTI), PT/INR, PTT, Type and Screen.
    • Ultrasound of the abdomen/pelvis (or CT abdomen/pelvis with IV contrast).
  4. Therapeutics & Consultation (Minute 4–6):
    • Surgical Consult (General Surgery stat for Appendectomy).
    • IV Morphine or Fentanyl for pain control (does NOT obscure peritoneal exam).
    • IV Ondansetron for nausea.
    • Pre-op IV Antibiotics: Cefoxitin 2g IV stat, OR Ceftriaxone 1g IV + Metronidazole 500mg IV stat.
  5. Final 2 Minutes:
    • Transfer to OR / Inpatient surgical service.
    • Counsel on post-op wound care, smoking cessation, and activity restrictions.

Case Prototype 2: Diabetic Ketoacidosis (DKA)

Clinical Setup

  • Presentation: 19-year-old female with Type 1 Diabetes presenting with 2 days of nausea, vomiting, diffuse abdominal pain, deep rapid breathing (Kussmaul), and fruity breath odor.

Optimal Order Pathway

  1. Immediate Orders (Minute 0–1):
    • Pulse oximetry, continuous cardiac monitor.
    • 2 large-bore IVs, Normal saline 0.9% IV 1000 mL/hr wide open.
    • Accu-Chek / Fingerstick glucose stat, Urinalysis stat (ketones, glucose).
  2. Diagnostics (Minute 1–3):
    • BMP stat (Check Serum Potassium, Sodium, Bicarbonate, Anion Gap).
    • Serum Ketones (beta-hydroxybutyrate), ABG (metabolic acidosis), CBC, Serum Osmolality.
    • ECG stat (Peaked T waves vs U waves).
  3. Therapeutics (Minute 3–10):
    • CRITICAL: Check Potassium BEFORE starting insulin:
      • If K+ < 3.3 mEq/L: HOLD insulin, give IV KCl until K+ ≥ 3.3.
      • If K+ ≥ 3.3 mEq/L: Start Regular Insulin IV infusion (0.1 units/kg/hr).
    • When glucose falls < 200 mg/dL: Switch IVF to D5 0.45% Normal Saline to prevent hypoglycemia while keeping insulin drip running until anion gap closes.
    • Repeat BMP and blood glucose every 1 to 2 hours.
    • Transfer to ICU.
  4. Final 2 Minutes:
    • Counsel patient on insulin compliance, sick-day rules, home blood glucose monitoring, diabetes educator consult.
