Critical Care Paramedic Exam Review
Questions with Detailed Verified
Answers

Question: Medication administration
Answer: Pinching the tubing above the medication port stops backflow and
ensures the medication moves toward the patient.


Question:Endotracheal intubation position
Answer: The sniffing position aligns the airway axes for optimal visualization
during intubation.


Question:Wrist position relative to elbow
Answer: The wrist is distal to the elbow.


Question:Sensory receptors for pH changes
Answer: Chemoreceptors detect blood chemistry changes, especially pH and
CO₂.


Question:Quiet breathing
Answer: Inspiration involves muscular contractions and expiration is passive
during normal, relaxed breathing.


Question:Normal breathing movement

Answer: Eupnea is the term for normal breathing with active inhalation and
passive exhalation.


Question:Normal pH range
Answer: Blood pH is tightly controlled between 7.35 and 7.45 for metabolic
function.


Question:Anaphylactic shock characteristics
Answer: Anaphylactic shock causes systemic vasodilation and airway
swelling.


Question:Pulmonary edema classification
Answer: Cardiogenic shock leads to left-sided heart failure and fluid backup
into the lungs.


Question:Physiologic changes in tissue anoxia
Answer: Oxygen deprivation suppresses the Kreb's cycle and triggers
anaerobic metabolism.


Question:Shock or hypoperfusion definition
Answer: The fundamental problem in all types of shock is inadequate
perfusion and oxygen delivery.


Question:Body's response to shock
Answer: Volume loss reduces venous return and arterial pressure, impairing
cardiac output.

Question:Detection of arterial pressure decrease
Answer: Baroreceptors in the carotid sinuses and aortic arch detect pressure
changes and trigger compensatory responses.


Question:Factors affecting cardiac output
Answer: Cardiac output = stroke volume × heart rate.


Question:Pericardial Tamponade
Answer: A condition that impedes forward blood flow, leading to obstructive
shock.


Question:Tension Pneumothorax
Answer: A condition that impedes forward blood flow, leading to obstructive
shock.


Question:Pulmonary Embolism
Answer: A condition that impedes forward blood flow, leading to obstructive
shock.


Question:Obstructive Shock
Answer: A type of shock characterized by impeded forward blood flow.


Question:Late Progressive Stage of Shock
Answer: Indicated by a falling systolic blood pressure to <90 mm Hg.


Question:Septic Shock

, Page | 4

Answer: A type of shock classified as distributive due to peripheral
vasodilation and capillary permeability.


Question:Alpha Adrenergic Receptor Stimulation
Answer: Causes vasoconstriction to raise blood pressure.


Question:Beta Adrenergic Receptor Stimulation
Answer: Enhances inotropy, increases dromotropy, and causes
bronchodilation, but does not cause vasoconstriction.


Question:Intravenous Therapy for Hypoperfusion
Answer: Helps treat hypoperfusion by increasing preload.


Question:Neurogenic Shock
Answer: Least likely cause of hypotension, tachycardia, and absent radial
pulses, often presents with bradycardia and warm skin.


Question:Classic Signs of Neurogenic Shock
Answer: Hypoperfusion, bradycardia, and warm, dry skin below the injury site
following a traumatic event.


Question:Patient Privacy in Radio Reports
Answer: Patient's name should not be relayed to preserve privacy.


Question:Systolic Blood Pressure
Answer: The pressure against the walls of blood vessels during ventricular
contraction.
