Types of Shock NCLEX Review: Key Signs, Nursing Priorities, and How to Differentiate

Shock is a life-threatening condition that requires immediate nursing intervention. On the NCLEX exam, you’ll be expected to recognize the different types of shock, identify early warning signs, and take appropriate nursing action quickly.

This article breaks down each type of shock, highlights the key indicators that differentiate them, and offers helpful strategies to prepare for NCLEX-style questions.

What Is Shock?

Shock is a state of inadequate tissue perfusion resulting in cellular and organ dysfunction. If left untreated, shock can lead to multi-organ failure and death. As a nurse, your job is to detect shock early, respond quickly, and know the specific interventions based on the cause.

Shock is categorized into four main types: hypovolemic, cardiogenic, distributive, and obstructive — each with its own pathophysiology and nursing implications.

1. Hypovolemic Shock

Cause:
Significant loss of fluid or blood volume

Common causes:

Hemorrhage
Dehydration
Severe burns

Signs & Symptoms:

Low blood pressure
Rapid heart rate
Cool, pale skin
Decreased urine output
Weak peripheral pulses

NCLEX Tip: Hypovolemic shock is commonly caused by trauma or GI bleeding. Prioritize restoring fluid volume with IV fluids and blood products.

2. Cardiogenic Shock

Cause:
The heart cannot pump enough blood to meet body demands.

Common causes:

Myocardial infarction (MI)
Heart failure
Arrhythmias

Signs & Symptoms:

Hypotension
Chest pain
Pulmonary congestion
Cool and clammy skin
Weak, rapid pulse

3. Distributive Shock

Distributive shock is characterized by widespread vasodilation and includes septic, neurogenic, and anaphylactic shock.

Septic Shock

Cause: Systemic infection
Signs: Fever, tachycardia, low BP, warm/flushed skin → later cold/clammy
Review: Infection Control Practices for NCLEX

Neurogenic Shock

Cause: Spinal cord injury
Signs: Hypotension, bradycardia, warm dry skin, flaccid paralysis

Anaphylactic Shock

Cause: Severe allergic reaction
Signs: Airway swelling, stridor, hives, hypotension, bronchospasm

4. Obstructive Shock

Cause:
Physical obstruction that impedes blood flow

Common causes:

Pulmonary embolism
Tension pneumothorax
Cardiac tamponade

Signs & Symptoms:

Hypotension
Jugular venous distention (JVD)
Shortness of breath
Chest pain
Cyanosis

How to Differentiate Types of Shock (Key Indicators)

Blood Pressure

Usually ↓ in all forms
Septic may present with initially normal BP, then drops

Heart Rate

↑ in hypovolemic, septic, and anaphylactic shock
↓ in neurogenic shock

Skin Appearance

Cool/clammy: hypovolemic, cardiogenic
Warm/flushed: early septic or neurogenic
Hives/edema: anaphylaxis

Urine Output

↓ in most shock types
May be normal early in sepsis

Conclusion

Understanding the different types of shock — and how to differentiate them — is crucial for NCLEX success and real-world practice.

Type	Key Cause	Notable Sign
Hypovolemic	Volume loss	Cool skin, low BP
