A client with COPD asks the nurse about the purpose of an arterial blood gas (ABG) test. What should the nurse explain?

"This test evaluates lung function and airflow in your lungs."

"It measures the oxygen and carbon dioxide levels in your blood."

"An ABG test assesses for the presence of respiratory infections."

"It identifies specific bacteria causing your respiratory symptoms."

Answer and Explanation

The Correct Answer is B

A) Incorrect. While ABG tests provide information about blood gases, they do not directly evaluate lung function and airflow.

B) Correct. Arterial blood gas (ABG) tests measure the levels of oxygen and carbon dioxide in the blood, which can help assess respiratory function and acid-base balance.

C) Incorrect. ABG tests do not directly assess for the presence of respiratory infections; they focus on blood gas parameters.

D) Incorrect. Identifying specific bacteria causing respiratory symptoms is typically done through sputum cultures and sensitivity tests, not ABG tests.

Correct Answer is C

Explanation

A) Incorrect. Chest X-rays can provide information about the lungs but are not the primary diagnostic tool for assessing lung function in COPD.

B) Incorrect. A complete blood count (CBC) may reveal signs of infection or anemia but does not assess lung function.

C) Correct. Pulmonary function tests (PFTs), such as spirometry, are the primary diagnostic tool for assessing lung function in COPD. They measure parameters like forced expiratory volume in one second (FEV1) and forced vital capacity (FVC).

D) Incorrect. An electrocardiogram (ECG) is used to assess the electrical activity of the heart and is not a primary tool for diagnosing COPD.

A. Mild wheezing on auscultation B. Increased energy levels and activity tolerance C. Decreased shortness of breath during exertion D. Cyanosis of the lips and fingertips

Correct Answer is D

Explanation

A) Incorrect. Mild wheezing can occur in stable COPD and may not necessarily indicate exacerbation.

B) Incorrect. Increased energy levels and activity tolerance would be positive signs but are not indicative of exacerbation.

C) Incorrect. Decreased shortness of breath during exertion would be a positive change, suggesting improved control of COPD.

D) Correct. Cyanosis (bluish discoloration) of the lips and fingertips is a sign of hypoxia and indicates exacerbation or worsening of COPD.
