Question

A respiratory therapist is reviewing the medical record of a 69-year-old patient admitted 2 hours prior. The record indicates the patient has chronic hypercapnia, emphysema, and an 80 pack-year history of smoking. Admission documentation shows the patient reported with moderate dyspnea. Currently, the patient is sleeping but arouses with significant verbal stimulation. The therapist should FIRST recommend?

1) arterial blood gas analysis
2) single-breath nitrogen elimination test (SBN2)
3) pulmonary function testing
4) CO-Oximetry

Answer 1

The respiratory therapist should first recommend an arterial blood gas analysis for the patient with chronic hypercapnia, emphysema, and a history of smoking to assess the patient’s current gas exchange status (1).

Step-by-step explanation:

In the case of the 69-year-old patient with a history of chronic hypercapnia, emphysema, and extensive smoking, the prioritized assessment by a respiratory therapist should be to check the patient's current gas exchange status. Considering the patient's moderate dyspnea upon admission and chronic lung conditions, the respiratory therapist should FIRST recommend an arterial blood gas (ABG) analysis.

This test will provide immediate data on the patient's oxygenation, carbon dioxide levels, and acid-base balance, which is critical for determining the appropriate treatment strategy for the symptoms and underlying chronic conditions.
