Nur 113 Oxygenation Exam Questions And Accurate Solutions
Oxygenation - Answer The process of delivering oxygen to the blood by diffusion from
the alveoli following inhalation into the lungs.
increased CO2 from respiratory acidosis causes? - Answer vasodilation of the cerebral
arteries, increased intracranial pressure and decreased Level of consciousness (LOC)
-headache
-irritable
How does acid base balance affect the RR - Answer increase RR excretes more CO2
decreased RR retains more CO2
how would any type of trauma effect cellular regulation? - Answer pt may have
decreased blood carrying O2 cells and blood will shunt to vital organs and leave
peripheries
-peripheral cyanosis
-slow cap refill
-cold extremities
-pallor
-lethargic
-orthostatic hypotension
how does CO2 and O2 effect cognition? - Answer increased CO2=decreased O2=
decreased LOC
if we don't get enough O2 the body can experience discomfort how? - Answer chest or
kidney pain
, -give pain meds if necessary
how can decrease of perfusion affect the body? - Answer -decrease O2 level
-blood shunting to vital organs (brain and heart)
-kidneys can decrease UOP, sign that pt status is declining
considerations pregnancy - Answer -increase need of O2 (supporting another life)
-increased RR (uterus pushing diaphragm)
-nasal stuffiness and epistaxis (estrogen)
active labor changes - Answer increased RR due to pain (hyperventilation)
supplemental O2 during labor
foramen ovale - Answer Allows blood to enter the left atrium from the right atrium.
should close after birth
ductus arteriosus - Answer connects the pulmonary artery to the aorta, by passing the
lungs
-fetal lungs are filled with fluid
-close after birth
-pressure from natural birth pushes the fluid out
c-section baby, lungs usually have to be stimulated by aggressive rubbing to stimulate
them to take a deep breath to clear lungs of fluid
Ductuc venosus - Answer -Allows umbilical vein blood to bypass the liver and merge
with blood going through the vena cava
-The purpose is to bring the blood to the heart faster
