Question 4 of 5
A nurse is caring for a patient who has been hospitalized for an acute asthma exacerbation. Which testing method might the nurse use to measure the patient's oxygen saturation?
Correct Answer: B
Rationale: Pulse oximetry is used to obtain baseline information about the patient's oxygen saturation level and is also performed for patients with asthma. Diffusion capacity estimates the patient's ability to absorb alveolar gases and determines if a gas exchange problem exists. Maximal respiratory pressures help evaluate neuromuscular causes of respiratory dysfunction. Both tests are usually performed by a respiratory therapist. The physician or other advanced practice professional can perform a thoracentesis at the bedside with the nurse assisting, or in the radiology department.
Question 5 of 5
Which of the following is TRUE about Expiration?
Correct Answer: A
Rationale: Expiration is typically a passive process at rest, relying on the elastic recoil of the lungs and chest wall rather than active muscle effort.
