⼀Answer:⼀ Myocardial infarction
Left sided heart failure
⼀Answer:⼀ Left ventricle not pumping effectively; think everything
with the lungs!!!! (Dyspnea, chronic cough, wheezing)
Right sided heart failure
⼀Answer:⼀ Right ventricle not pumping effectively; EVERYTHING
BESIDES LUNGS (edema, JVD, ascites)
Examining the lungs steps in order....
⼀Answer:⼀ Inspection
palpation
percussion
auscultation
specific health promotion implementation for patients would be....
⼀Answer:⼀ Vaccinations
health and lifestyle
environmental pollutants
What is hemoglobin responsible for?
⼀Answer:⼀ Carrying O2 (97%) and CO2
Pt that are acidotic (sepsis, COPD) have impaired what?
, Page | 3
⼀Answer:⼀ Gas exchange
O2 transport relies on _____ and ______
⼀Answer:⼀ Ventilation and perfusion
What is ventilation?
⼀Answer:⼀ movement of air in and out of the lungs
What is perfusion?
⼀Answer:⼀ blood flow
What regulates voluntary control in the brain?
⼀Answer:⼀ Cerebral cortex
What is the myocardial pump?
⼀Answer:⼀ System that delivers O2, nutrients to tissues, and
facilitates removal of waste through resp, renal, and digestive systems
Stroke volume blood is ejected from the ventricles during what?
⼀Answer:⼀ Systole
What two things lower stroke volume?
⼀Answer:⼀ Hemorrhage and dehydration
Which coronary artery has the most blood supply?
, Page | 4
⼀Answer:⼀ Left
What is the amount of blood flow ejected every minute from the
left ventricle?
⼀Answer:⼀ 4-8 L/min
anemia is
⼀Answer:⼀ Lower than normal hemoglobin levels leading to fatigue,
decreased activity, increased breathlessness, and increased HR and
pallor
Hypovolemia
⼀Answer:⼀ Shock and dehydration cause extracellular fluid loss and
less blood volume- results in hypoxia, increased HR, and
vasoconstriction
How does pregnancy affect chest wall movement?
⼀Answer:⼀ Baby pushes up fetus during pregnancy
How does obesity affect chest wall movement?
⼀Answer:⼀ Patients who are morbidly obese have reduced lung
volumes (sleep apnea) and are likely to develop atelectasis and
pneumonia after surgery
COPD
⼀Answer:⼀ Cause barrel chest and can lead to decreased O2
For chronic lung disease, you should not give more than how
many liters per minute?
