Which information does a pulse oximeter Saturation of hemoglobin with oxygen 3 multiple choice options
measure?
What percentage of the air we breathe is 21% 3 multiple choice options
oxygen?
Which muscle group is primarily Diaphragm 3 multiple choice options
responsible for the inflation of the lungs?
When gas exchange is impaired, both the - compensate
lungs and heart can - homeostasis
(compensate/worsen) for a limited - damage
time by altering the respiratory rate,
heart rate, or both, allowing the body
to return to
(disequilibrium/homeostasis.) When
compensatory mechanisms fail, the result
may lead to tissue and organ
(damage/hypertrophy) or death.
For each underlying pathophysiologic Hy poxia
change, specify if the change is - Not enough functional red blood cells
associated with hypoxia or hypoxemia. - Blood is not reaching the tissues
- Cyanide poisoning
- Hypoventilation
- Oxygen is not reaching the alveoli Hy poxemia
- Not enough functional red blood cells - Hypoventilation
- Diffusion impairment - Oxygen is not reaching the alveoli
- Blood is not reaching the tissues - Diffusion impairment
- Cyanide poisoning

Situation: An older adult arrives at the Impaired gas exchange 3 multiple choice options
emergency department (ED) with a
productive cough, fatigue, and shortness
of breath that has worsened over the
last three days.
Background: No history of medical
problems; takes no prescription
medications; occasionally takes
acetaminophen for pain; does not smoke.
Assessment: T 98.6°F (37°C), BP 155/85, P
120, R 30, oxygen saturation (O2 sat) 88%
on room air; lung sounds diminished right
lower lobe with rhonchi present;
heart
regular rhythm with no murmurs or
extra heart sounds.
The client is admitted with dyspnea. They
are tachypneic at 30 with a blood
pressure of 160/90, pulse of 125 and
regular, and oxygen saturation is 88%.
What is the priority nursing diagnosis
for this client?
