❤️ PATHOPHYSIOLOGY
Shock is best defined as this condition.
What is inadequate cellular perfusion (hypoperfusion)?
This type of shock results from pump failure.
What is cardiogenic shock?
This stage of shock is characterized by anxiety, restlessness, and tachycardia.
What is compensated shock?
The first priority after recognizing shock.
What is begin immediate treatment and control life-threatening bleeding?
A patient is anxious, tachycardic, pale, cool, and has a BP of 124/82.
Question:
What stage of shock?
What is Compensated shock.
The three components of the "perfusion triangle."
What is
Name the three classic causes of obstructive shock.
What is
A falling blood pressure usually indicates this stage.
What is decompensated shock?
Two treatments nearly every shock patient receives.
What is
A trauma patient has JVD, muffled heart sounds, and narrowing pulse pressure.
Question:
What is the most likely diagnosis?
What is Cardiac tamponade.
This physiologic response causes tachycardia, stronger cardiac contractions, and peripheral vasoconstriction during early shock.
What is sympathetic nervous system activation (fight-or-flight response)?
Match the shock type with the cause.
Massive bleeding
Severe infection
High spinal cord injury
Allergic reaction
What is
Blood pressure is often this during the early stages of shock.
What is normal (maintained by compensation)?
This medication is indicated for severe anaphylactic shock.
What is epinephrine?
A patient has unilateral absent breath sounds, hypotension, JVD, and severe respiratory distress.
Question:
What shock is occurring?
What is Obstructive shock from tension pneumothorax.
Pulse pressure is calculated by subtracting these two numbers.
What is systolic minus diastolic blood pressure?
This obstructive shock presents with Beck's triad.
What is cardiac tamponade?
List FOUR findings of compensated shock.
What is
True or False:
Patients in cardiogenic shock should receive nitroglycerin because they have chest pain.
What is False. Cardiogenic shock patients are hypotensive and should not receive nitroglycerin.
Following a bee sting, a patient develops wheezing, hives, facial swelling, hypotension, and stridor.
Question:
What type of shock?
What is Anaphylactic shock.
Arrange these in the correct order of oxygen delivery.
What is 2 → 4 → 1 → 3
This type of shock is caused by widespread vasodilation after a high spinal cord injury.
What is neurogenic shock?
An infant's blood pressure suddenly begins falling after severe trauma.
What is the child is in late/decompensated shock and is critically ill.
Match the shock with its priority intervention.
Cardiac tamponade
Tension pneumothorax
Septic
Hypovolemic
What is
Hypotension, bradycardia, and warm, dry skin after a cervical spinal injury.
What kind of shock?
What is neurogenic shock?
