Unit 3 Flashcards
Right sided heart failure
- Maybe secondary to chronic pulmonary problems
- distended jugular veins
- anorexia and c/o GI dz
- weight gain
- dependent edema
- enlarged liver and spleen
- ascites
- increase peripheral venous pressure
- fatigue
Common clinical signs of heart failure
Swelling in the ankles and legs Swelling in the ABD Pleural effusion Coughing Tiered SOB Pulmonary edema Pumping action of the heart grows weaker
Auscultation, listening for abn heart and long sounds
Pulmonary crackles due to fluid in the lungs
Heart murmur due to damaged valves
Rapid pulse
S3 Gallup
Activity and exercise
3 functions important to daily life
Mobility
Independent self care
Exercise and leasure
Activity and exercise
4 main support systems of ENERGY EXPENDITURE
Neurological
Musculoskeletal
Cardiovascular
Respiratory
Assessment of Activity and exercise
Can reveal lack of exercise which leads a sedentary lifestyle
- poor muscle tone
-balance problems
-mental and physical fatigue
Ask pt” what is your pattern of exercise?”
Activity and exercise
Lead to obesity
Minimal exercise
Sedentary lifestyle
Imbalance nutrition
Obesity places pt at risk for
Coronary artery dz Cerebral vascular accident (CVA) Diabetes mellitus Decreased activity tolerance Impaired mobility
Monitoring activity tolerance and the ability to perform them is necessary to…
Identify pt
strength
Physical ability
Risk factors associated with intolerance
Physiologic responcea to activities/exercise
Assess body’s attempt to meet O2 demands
Assesses for effective cardiac output( assessing pulse)
O2 delivery to tissue
( ck lab V/s notes for values)
Cardiovascular system
Heart rate
Heart rate is a good indicator of activity intolerance
Should return to (baseline) normal after 5 min of exercise
Continued increase is abn (can taxi the heart)
Cardiac output (c/o)
The amount to blood ejected from the left ventricle with each contraction
Cardiac output (c/o) equals
E heart rate(hr)X the stroke volume(SV)
SV= the amount of blood that enters the arteries with each contraction
C/o= 5 liters/ minute(range =4-8 liters/minute)
Heart rate increases in activity causing an increase in O2 to tissue.
Stroke volume (SV)
Equals the amount of blood that enters the arteries with each contraction
The heart
Size of your fist(varies per person) Base- top of heart Apex- bottom of heart Great vessels attached: Aorta Pulmonary artery Sup/inferior vena cava Pulmonary veins
