NURSING STUDY GUIDE 2026/2027
Primary Survey - ANS ✔✔Airway
Breathing
Circulation
Disability
Exposure
when do you move on from primary survey? - ANS ✔✔when you know they are full stable
when do we go back to primary survey? - ANS ✔✔if something in the pt changes
Purpose of primary survey - ANS ✔✔detect life-threatening problems and provide emergency
care
priority over ABC - ANS ✔✔Hemorrhage
Secondary Survey - ANS ✔✔a head-to-toe physical assessment; an additional assessment of a
patient to determine the existence of any injuries other than those found in the primary survey
The purpose of triage is to: - ANS ✔✔prioritize patients by order of injury severity.
Categories of Triage - ANS ✔✔--Emergent Category (Class I)- highest priority is given to clients
who have lifethreatening injuries but are likely to recover
--Urgent Category (Class II)- second highest priority is given to clients who have major injuries
that are not yet life threatening and can usually wait 45-60 min for treatment
, --Nonurgent Category (Class III)- the next highest priority is given to clients who have minor
injuries that are not life-threatening and dont need immediate attention
--Expectant Category (Class IV)-the lowest priority is given to clients who are not expected to
live and will be allowed to die naturally. comfort measures may be provided, but restorative will
not.
three components of gas exchange - ANS ✔✔ventilation diffusion and perfusion
Ventilation - ANS ✔✔movement of air in and out of the lungs
Diffusion in gas exchange - ANS ✔✔Exchange of respiratory gases in the alveoli and capillaries
Perfusion - ANS ✔✔The supply of oxygen to and removal of wastes from the cells and tissues of
the body as a result of the flow of blood through the capillaries.
physiologic components of gas exchange - ANS ✔✔gas exchange delivery and consumption
acid-base balance - ANS ✔✔equilibrium between acid and base concentrations in the body
fluids
arterial blood gases - ANS ✔✔clinical test on arterial blood to identify the levels of oxygen and
carbon dioxide
Arterial blood gas normal ranges PH - ANS ✔✔7.35-7.45
Arterial blood gas normal ranges PaO2 - ANS ✔✔80-100mm Hg
Arterial blood gas normal ranges PaCO2 - ANS ✔✔35-45 mm Hg
