Shock MCQs Part 2 – Advanced Clinical Cases
This section focuses on advanced clinical reasoning in shock management. It is designed for medical students preparing for exams and emergency medicine rotations.
📌 Key Concepts
Shock is a state of systemic hypoperfusion leading to organ dysfunction. Understanding hemodynamic patterns is essential:
- Hypovolemic → low preload
- Cardiogenic → pump failure
- Septic → vasodilation + high CO early
- Obstructive → mechanical blockage
🧠 Clinical MCQs
1. A patient with pneumonia presents with fever, hypotension, warm extremities. Diagnosis?
A) Hypovolemic
B) Cardiogenic
C) Septic
D) Neurogenic
Warm extremities + infection → vasodilation (early septic shock)
2. MI patient with pulmonary edema and low BP indicates?
A) Septic
B) Cardiogenic
C) Hypovolemic
D) Obstructive
3. Trauma patient with flat neck veins suggests?
A) Cardiogenic
B) Hypovolemic
C) Septic
D) Neurogenic
4. Increased JVP + hypotension suggests?
A) Hypovolemic
B) Cardiogenic / Obstructive
C) Septic
D) Neurogenic
5. First-line treatment in anaphylactic shock?
A) Steroids
B) Antihistamines
C) IM adrenaline
D) Fluids only
6. Elevated lactate indicates?
A) Good perfusion
B) Anaerobic metabolism
C) Kidney failure
D) Infection only
7. Decreased SVR is seen in?
A) Septic shock
B) Hypovolemic
C) Cardiogenic
D) Obstructive
8. Pulmonary embolism causes?
A) Cardiogenic
B) Obstructive
C) Septic
D) Neurogenic
📊 Clinical Summary
✔ Cardiogenic → inotropes
✔ Septic → antibiotics + fluids
✔ Obstructive → relieve obstruction
