NURS 325 FINAL EXAM RETAKE FALL-SPRING PRACTICE QUESTIONS AND ANSWERS
GRADED A+
gas exchange - (ANSWER)the process by which oxygen is transported to cells and carbon dioxide is
transported out of cells
COPD - (ANSWER)-condition that causes changes or collapses the alveoli
-airflow limitation that is not fully reversible by the loss of elastic recoil and airflow obstruction due to
hyper secretion of mucus, bronchospasm, and mucosal edema
impairment of gas exchange occurs because - (ANSWER)-ineffective ventilation
-reduced capacity for gas transportation
-inadequate perfusion
Ventilation, transport and perfusion - (ANSWER)-starts with getting air into the lungs, availability of
hemoglobin for oxygen, and movement of the blood
-its a well oiled machine, if you have one thing wrong, they all shut down.
Consequences of impaired gas exchange: Mild impairment - (ANSWER)fatigue, increase in HR and RR
Consequences of impaired gas exchange: more severe - (ANSWER)respiratory acidosis
consequence of impaired gas exchange: prolonged - (ANSWER)cellular ischemia and necrosis death
PAD vs PVD - (ANSWER)-Arterial: having a hard time getting the blood to where you want it (see
necrotic/black)
-Venous: cant get the blood back to the heart
(see edema)
population risk factors for impaired gas exchange: Infants - (ANSWER)they have fetal hemoglobin, their
RBC dies quicker and they do not have the ability to transfer oxygen on the hemoglobin (anemia at 3
months)
, NURS 325 FINAL EXAM RETAKE FALL-SPRING PRACTICE QUESTIONS AND ANSWERS
GRADED A+
population risk factors for impaired gas exchange: children - (ANSWER)less alveoli surface where the gas
exchange can occur, narrowing at the branching of the peripheral airways (choke)
population risk factors for impaired gas exchange: older adults - (ANSWER)-physiological changes when
we age
-chronic illness, stiffening of the chest, loss of chest muscles, loss of recoil and elasticity
Nursing interventions done to increase perfusion - (ANSWER)-compression devices (venous return)
-mobility of pt
-cessation of smoking
-diet (heart healthy diet; less cholesterol)
Individual risk factors for impaired gas exchange - (ANSWER)-age (older adults it is harder to breathe)
-smoking (vasoconstriction of vessels)
-presence of COPD, HF, Cystic fibrosis
-immunosuppression
-reduced state of cognition/brain injury (increased risk for aspiration)
-prolonged immobility (DVT)
Oxygen delivery devices - (ANSWER)-nasal cannula
-simple face mask (short term)
-partial/non-rebreather mask (short term)
-venturi mask (precise high flow)
-high flow nasal cannula
Signs and Symptoms of impaired perfusion - (ANSWER)-discoloration of skin (pale/dark)
-clubbing
