Verified Solutions
What causes the tertiary effects of blast traumas? - ANSWER
Results from individuals being thrown by the blast wind. Injuries
include hole or partial body translocation from being thrown
against a hard service: blunt or penetrating trauma's, fractures,
traumatic amputations.
What causes quarternary effects of blast traumas? - ANSWER
All explosion related injuries, illnesses, or diseases not due to the
first three mechanisms. Injuries include external and internal
burns, crush injuries, closed and open brain injuries, asthmatic or
breathing problems from dust smoke or toxic fumes, angina, or
hyper glycemia and hypertension.
What causes quinary effects of blasts traumas? - ANSWER
Those associated with exposure to hazardous materials from
radioactive, biologic, or chemical components of a blast. Injuries
include a variety of health effects depending on agent.
What are the three processes that transfer oxygen from the air to
the lungs and blood stream - ANSWER Ventilation: the active
mechanical movement of air into and out of the lungs; diffusion:
the passive movement of gases from an area of higher
concentration to an area of lower concentration; and perfusion:
the movement of blood to and from the lungs as a delivery
medium of oxygen to the entire body.
When would you use a nasopharyngeal airway versus an oral
pharyngeal airway? - ANSWER Nasopharyngeal airways is
contraindicated in patients with facial trauma or a suspected
, basilar skull fracture. Oral pharyngeal airways is used in
unresponsive patients unable to maintain their airway, without a
gag reflex as a temporary measure to facilitate ventilation with a
bag mask device or spontaneous ventilation until the patient can
be intubated.
Describe the measurement of an NPA - ANSWER Measure from
the tip of the patient's nose to the tip of the patients earlobe.
Measurement of an OPA - ANSWER Place the proximal end or
flange of the airway adjunct at the corner of the mouth to the tip of
the mandibular angle.
True or false: NPAs and OPAs are definitive airways. -
ANSWER False. When placing one of these? One should
consider the potential need for a definitive airway.
Name the three ways to confirm ETT placement - ANSWER
Placement of a CO2 monitoring device, Assessing for equal chest
rise and fall, and listening at the epigastrium and four lung fields
for equal breath sounds.
When capnography measurement reads greater than 45MMHG,
the nurse should consider increasing or decreasing the ventilation
rate? - ANSWER Increasing the ventilation rate. Doing so would
allow the patient to blow off retained CO2.
When capnography measurement reads less than 35MMHG, the
nurse should consider increasing or decreasing the ventilation
rate? - ANSWER Decreasing the ventilation rate. By doing so,
the nurse allows the patient to retain CO2.
What are the three stages of shock - ANSWER Compensated,
