,For each underlying pathophysiologic change, specify if Hypoxia
the change is associated with hypoxia or hypoxemia. - Not enough functional red blood cells
- Blood is not reaching the tissues
- Hypoventilation - Cyanide poisoning
- Oxygen is not reaching the alveoli
- Not enough functional red blood cells Hypoxemia
- Diffusion impairment - Hypoventilation
- Blood is not reaching the tissues - Oxygen is not reaching the alveoli
- Cyanide poisoning - Diffusion impairment
Match each device with name and then identify the piece Spirometry: Ventilation
of gas exchange it measures: Oximeter: Hypoxemia
Lab Testing: Hypoxemia
Device Name: Chest X-Ray: Ventilation
- Spirometry
- Oximeter
- Lab Testing
- Chest X-Ray
Gas Exchange Measured:
- Ventilation
- Hypoxemia
Match each device with its name and then identify the - Echocardiogram: Dysfunctional Valves
piece of gas exchange it measures. - Lab Testing: Myocardial infarction
- Electrocardiogram: Dysrhythmia
Type of Test: - Cardiac Catheterization: Altered cardiac output; Infarction/Ischemia
Echocardiogram - Angina, Dysfunctional valves, VQ
mismatch
Lab Testing - Myocarditis, Myocardial infarction, VQ
mismatch
Electrocardiogram - Aortic aneurysm, Decreased blood
flow, Dysrhythmia
Cardiac Catheterization - Decreased blood flow, Altered
cardiac output; Infarction/Ischemia, Myocarditis
For each sign or symptom listed, specify the prioritized Ventilation Device: Cannot take a deep breath, Stopped breathing
device for assistance: ventilation device, oxygen, or
inhaled medication. Oxygen: Oxygen saturation 78%
- Ventilation Device Inhaled Medication: Asthmatic wheezing
- Oxygen
- Inhaled Medication
SIGN/SYMPTOM
Oxygen saturation 78%
Cannot take a deep breath
Asthmatic wheezing
Stopped breathing
, Situation: An older adult arrives at the emergency Impaired gas exchange
department (ED) with a productive cough, fatigue, and
3 multiple choice options
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?

regular rhythm with no murmurs or extra heart sounds.
The chest x-ray results confirm community-acquired
pneumonia. Both the electrocardiogram and
echocardiogram are normal. Based on these results, what
is the most likely cause of the client’s increased
respirations?
