Question

if a patient is found to have an oxygen level that is too low, what are some ways that supplemental oxygen can be delivered to help increase blood oxygen levels? (choose all that apply)

• nasal canula
• mask
• postural drainage
• endotracheal tube

question 33
2.5 pts
if a patient has pneumonia, the doctor may order a test to determine which bacteria is growing in the lung secretions, as well as which antibiotic would most effectively treat the infection. what is the name of this test?

• sputum cytology
• sputum culture and sensitivity
• oximetry
• spirometry

Identify oxygen delivery methods

The first question asks for ways supplemental oxygen can be delivered to help increase blood oxygen levels. Let's evaluate each option:

• nasal canula: A common device used to deliver supplemental oxygen through the nostrils. This is correct.
• mask: Oxygen masks (such as simple face masks or non-rebreather masks) are standard devices used to deliver oxygen. This is correct.
• postural drainage: This is a physical therapy technique used to clear mucus from the lungs, not a method to deliver supplemental oxygen. This is incorrect.
• endotracheal tube: A tube inserted into the trachea to maintain an open airway, which is connected to a ventilator to deliver high concentrations of oxygen. This is correct.

Determine the diagnostic test for pneumonia

The second question (labeled Question 33) asks for the name of a test used to determine which bacteria are growing in the lung secretions and which antibiotic would be most effective. Let's evaluate the options:

• sputum cytology: Examines cells in sputum under a microscope, primarily to look for cancer cells, not to identify bacteria or antibiotic sensitivity.
• sputum culture and sensitivity: A "culture" grows the bacteria present in the sputum to identify them, and a "sensitivity" test determines which antibiotics are effective at killing those bacteria. This matches the prompt perfectly.
• oximetry: Measures oxygen saturation in the blood, not bacteria.
• spirometry: Measures lung function and airflow volumes, not bacteria.
