Nursing 221 Final
Ventilation - correct answer ✔Process of moving air in/out of the lungs.
Perfusion - correct answer ✔Ability of the cardiovascular system to pump
oxygenated blood to tissues and deoxygenated blood to the lungs
Exchange of respiratory gases - correct answer ✔Organs, nerves, and
muscles of respiration need to be intact. CNS regulates the respiratory cycle.
Cardiac Output - correct answer ✔Amount of blood ejected from the left
ventricle. CO=SV*HR
Myocardial Blood flow - correct answer ✔Unidirectional flow through the
heart and to pulmonary/systemic circulation.
Coronary artery circulation - correct answer ✔Branch of systemic circulation
that supplies the myocardium w/ oxygen and nutrients and removes waste.
The left CA has the most abundant blood supply and feeds the more muscular
left ventricle myocardium.
Atelectasis - correct answer ✔Collapse of a lung
Preload - correct answer ✔End diastolic volume
Afterload - correct answer ✔Resistance to the left ventricular ejection.
,Hypoxia - correct answer ✔Low levels of oxygen in the blood.
Hypoxia-causes - correct answer ✔Low Hgb
Low diffusion of H20
Low tissue perfusion
Impaired ventilation
Early signs of hypoxia - correct answer ✔R-Restlessness
A-Anxiety
T-Tachycardia/Tachypnea
Elevated vital signs
Late signs of hypoxia - correct answer ✔B-Bradycardia/Bradypnea
E-Extreme restlessness
D-Dyspnea
Clubbing
Cyanosis
Adventitious breath sounds - correct answer ✔Crackles
Wheezes
Rhonci
Pleural friction rub
Stridor
Absent
,Crackles (rales) - correct answer ✔-Short, discrete, interrupted crackling
sound
-Caused by air passing through secretions/moisture.
Wheezes - correct answer ✔-High pitched whistling sound
-Air moving through narrow airways (constriction/obstruction).
Rhonci (gurgles) - correct answer ✔-Low pitched, rattling, resembling
snoring.
-Air moving through fluid-filled airways.
Pleural friction rub - correct answer ✔-Creaking/grating sound
-Rubbing together of inflammed pleural spaces.
Stridor - correct answer ✔-High pitched, piercing sound, most often heard
during inspiration.
-Obstruction in the high respiratory tree. (aspiration or foreign object).
Nursing diagnoses related to oxygenation - correct answer ✔Ineffective
airway clearence.
Ineffective breathing pattern.
Impaired gas exchange.
Activity intolerance.
Risk for aspiration.
Cheyne-Stokes - correct answer ✔Periods of increased respirations,
followed by periods apnea.
, Biot's respiration - correct answer ✔Irregular periods of inspiration/expiration
followed by apnea.
Bradypnea - correct answer ✔<12 respirations per minute
Tachypnea - correct answer ✔>20 breaths per minute
Ineffective airway clearence - correct answer ✔Pt. has difficulty maintaining
a patent airway.
Ineffective breathing pattern - correct answer ✔Loss of ventilation secondary
to altered breathing pattern.
Impaired gas exchange - correct answer ✔Decreased passage of O2/CO2
between alveoli and the vascular system.
Activity Intolerance - correct answer ✔Pt. is unable to complete physical
activity to the degree desired/required.
Risk for aspiration - correct answer ✔Pt. is in a state for increased aspiration
risk due to secretions, solids, or fluids.
Interventions to promote airway clearence - correct answer ✔-Effective
coughing
-Postural drainage/chest physiotherapy
-Monitor hydration
-Medications
