1 Shock Recognition and Initial Assessment Free Online FlashCards

What is shock?

Shock is a life-threatening state in which tissues receive inadequate perfusion.

Does normal blood pressure rule out early shock?

No. Blood pressure may remain normal early because the body compensates; worsening perfusion signs still warrant concern for shock.

What does ABCDE assessment cover in suspected shock?

Assess Airway and breathing, Circulation, Disability, and Exposure while arranging emergency help and beginning resuscitation under local protocols.

What is the primary problem in hypovolemic shock?

Hypovolemic shock results from too little circulating volume. Possible causes include bleeding, vomiting, diarrhea, burns, and dehydration.

What is the priority when hemorrhagic shock is suspected after injury?

Prioritize ABC support, rapidly identify and control bleeding, and activate emergency trauma care; do not wait for laboratory confirmation.

What findings can warn of shock?

Warning signs include tachycardia, tachypnea, confusion, cool or mottled skin, delayed capillary refill, weak pulses, and reduced urine output.

What can a rising lactate indicate—and what can it not do alone?

A rising lactate can support concern for tissue hypoperfusion, but lactate alone does not identify or prove shock.

What defines cardiogenic shock?

Cardiogenic shock occurs when the heart cannot pump enough blood; chest discomfort, breathlessness, crackles, or signs of pulmonary fluid backup may offer clues.

What is the primary problem in distributive shock?

Distributive shock involves blood vessels dilating and distributing blood abnormally. Warm or flushed skin and bounding pulses may occur, especially early.

How is septic shock classified, and what causes it?

Septic shock is distributive shock caused by infection and a dysregulated response. Skin may be warm early and cool later.

Which findings support anaphylactic distributive shock?

Sudden hypotension with hives, wheezing, and facial swelling after a medication supports anaphylactic distributive shock.

What causes obstructive shock?

Obstructive shock results from a mechanical problem blocking heart filling or blood flow; causes include tension pneumothorax, cardiac tamponade, and large pulmonary embolism.
