Question 1

Which device is typically used for delivering low-flow oxygen therapy?

Accepted Answer

Nasal cannula

Answer

A nasal cannula is the most commonly used device for delivering low-flow oxygen therapy, typically at flow rates between 1 and 6 liters per minute. It consists of two prongs that fit comfortably into the nostrils, providing supplemental oxygen without obstructing the patient's ability to eat, drink, or speak. Other devices like ventilators or CPAP machines deliver higher pressures or volumes, while nebulizers deliver medication.

Question 2

Which of the following is a potential side effect of long-term oxygen therapy?

Accepted Answer

Hypercapnia (increased CO2 levels)

Answer

In patients with chronic obstructive pulmonary disease (COPD) who have chronic hypercapnia, long-term oxygen therapy can sometimes suppress the hypoxic drive to breathe. This can lead to decreased ventilation and an increase in carbon dioxide (CO2) levels in the blood, resulting in hypercapnia. Careful monitoring of blood gas levels is essential to prevent this complication.
