A patient asks the nurse why they need to wear oxygen in the hospital and how it
works with blood cells. Which is the best response?
-Blood cells passing through the arteries in the lungs are oxygenated and then carry
oxygen to the body
-When you take in a breath the blood cells in your nose takes in the oxygen
-The blood that pumps through the heart takes in oxygen
-The blood receives oxygen from the bone marrow and carries it to the tissues -
ANSWER-Blood cells passing through the arteries in the lungs are oxygenated
and then carry oxygen to the body
How does severe hypoxia develop with pneumonia?

-Infection reduces effective compensation by the heart
-Acidosis depresses respirations
-Oxygen diffusion is impaired by the congestion - ANSWER-Oxygen diffusion
is impaired by the congestion

-Hematemesis
-Ischemia
-Cyanosis - ANSWER-Cyanosis
A 50-year-old presents with hypertension, hypoxemia, and tracheal deviation to the
left. Tests reveal that the air pressure in the pleural cavity exceeds barometric
pressure in the atmosphere. Based upon these assessment findings what does the
nurse suspect the patient is experiencing?
