Nurs 1113 Final Questions with 100% Verified Answers Latest
Update
Question: Answer:
-moving air in/out (mechanical) ventilation
-choking, obstruction -> needs airway cleared
Question: Answer:
-gas exchange across alveolar membrane diffusion
-pneumonia, edema -> needs O2
Question: Answer:
-pumping O2 blood to tissue and CO2 back perfusion
-shock, clots, heart failure
Question: Answer:
-cardiac output moving blood to all organs (the pump) central perfusion
Question: Answer:
blood actually reaching one capillary bed tissue perfusion
Question: Answer:
CO = stroke volume x heart rate Cardiac output
Question: Answer:
-amount of blood ejected from each ventricle during contraction. stroke volume
-determines preload, after load and contractility
Question: Answer:
more stretch = stronger squeeze until heart failure Frank-Starling
,Question: Answer:
-warm skin good perfusion
-alert/oriented
-pulses 2+ and 3+
-normal urine output
-cap refill <3 sec
Question: Answer:
-cool skin poor perfusion
-confusion
-weak pulses
-oliguria
Question: Answer:
-force that stretches heart muscle before it contracts preload
-amount of blood in ventricles at end of diastole
Question: Answer:
-strength of myocardial contraction contractility
-the greater the preload, the greater the stretch
Question: Answer:
-force that ventricles must exert to open the semilunar valves (aortic afterload
and pulmonic)
Question: Answer:
SA node -> AV node -> Bundle of His - > Purkinje conduction
Question: Answer:
-pacemaker of heart SA node
-60-100
Question: Answer:
-delays to let ventricles fill AV node
, Question: Answer:
-neuro Gas exchange needs 3 systems:
-respiratory
-cardiovascular
Question: Answer:
keeps alveoli open, without it -> atelectasis surfactant
Question: Answer:
-restlessness early hypoxia signs
-anxiety
-tachycardia
-mild dyspnear
-fatigue
Question: Answer:
-cyanosis late hypoxia signs
-bradycardia
-altered LOC
Question: Answer:
-reversible ischemia
-20 min window before heart cells die
-TIME IS MUSCLE/BRAIN
Question: Answer:
-necrosis infarction
-irreversible
Question: Answer:
low O2 in blood hypoxemia
Question: Answer:
low O2 in tissue hypoxia
