Final answer:
When caring for a patient with hypercapnia who is receiving supplemental oxygen, the nurse must use caution with the rate of administration to prevent respiratory depression.
Step-by-step explanation:
When caring for a patient with hypercapnia who is receiving supplemental oxygen, the nurse must use caution with the rate of administration. Hypercapnia is an abnormally elevated blood level of CO2. Supplemental oxygen increases the amount of oxygen available to the patient, but it does not decrease the CO2 levels.
If supplemental oxygen is administered too quickly or in high concentrations, it can suppress the patient's respiratory drive. This can lead to a further increase in CO2 levels due to reduced ventilation. Therefore, it is important for the nurse to monitor the patient closely and adjust the rate of administration to prevent respiratory depression.
