What this category covers
Physiological Adaptation covers caring for clients whose body systems are affected by acute, chronic or life-threatening illness. The practical/vocational nurse recognizes signs of worsening, provides focused care, responds to emergencies, reports changes to the RN or provider, and checks whether interventions worked.
Key concepts
Recognize and escalate
New confusion, breathing difficulty, falling blood pressure or a sudden change in the client's condition need prompt action and reporting.
Chronic conditions
Clients with diabetes, heart failure, kidney disease and lung disease need monitoring for flare-ups and complications.
Fluid and electrolyte balance
Weight changes, edema, intake and output, and lab values help show fluid and electrolyte problems.
Emergencies
In an emergency, call for help, stay with the client and begin the actions your training and facility policy allow, such as CPR.
