Shock
To protect vital organs, the body compensates by directing blood flow away from organs that are more tolerant of low flow, such as
A. skin, B. heart, C. brain, D. lungs
skin
What is the maximum time you should take to assess breathing and pulse in a unresponsive patient?
10 sec.
The decline in cardiac function that commonly occurs in late adulthood is most often related to?
atherosclerosis
All critical life functions are coordinated in which part of the brain?
Brainstem
What is a normal capnography reading?
35-45
Which of the following clinical signs is unique to anaphylactic shock?
A. Pallor, B. Dizziness, C. Wheezing, D. Hypotension
Wheezing
In most cases, cardiopulmonary arrest in infants and children is caused by
respiratory arrest
The anterior fontanelle fuses together between the ages of
9 and 18 months
How do you find cardiac output?
Stroke volume X HR
How long does it take for a pulse oximeter to reflect changes in a patient's oxygenation status?
up to 60 seconds
Septic shock occurs as a result from?
Severe infection
How can gastric distention be avoided when providing artificial ventilation?
Stop ventilations when you note chest rise.
At what age does separation anxiety typically peak in infants and small children?
10 to 18 months
In descending order name the structures of the lower airway.
Larynx, Trachea, carina, Bronchi, Bronchioles, Alveoli
During your assessment of a patient with respiratory distress, you hear wheezing when listening to breath sounds. This indicates:
a lower airway obstruction.
Three of the most common examples of obstructive shock are?
cardiac tamponade, tension pneumothorax, pulmonary embolism
What is the depth and rate of chest compressions in an adult patient.
2inchs
100 to 120 compressions a minute
When obtaining patient care orders from a physician via a two-way radio, it is important to remember that
the physician's instructions are based on the information you provide.
Name two key hormones of the sympathetic nervous system
Epinephrine and norepinephrine
Where does the phrenic nerve innervate and where does it originate.
Innervates with diaphragm with originates in the Cervical spine C3, C4, C5
What are the 4 types of shock and give an example of each.
Cardiogenic shock: heart failure
Obstructive shock: PE, tamponade, pnemo
Distributive shock: Septic, neuro, anaphylactic
Hypovolemic: Blood or fluid loss
List the two rhythm disturbances that are a result of sudden cardiac arrest.
VF, VT
The official transfer of patient care does not occur until the EMT
gives an oral report to the emergency room physician or nurse
What receptors monitors PH and adjust respirations and bicarbonate to maintain homeostasis
Chemoreceptors
How does positive-pressure ventilation affect cardiac output? And give two examples of positive pressure delivery.
It increases intrathoracic pressure, which decreases venous return to the heart and causes a decrease in cardiac output.
BVM, CPAP, Bi PAP
