A nurse is explaining the diagnostic evaluation for COPD to a client. Which test does the nurse emphasize as the primary diagnostic tool for assessing lung function in COPD?

Chest X-ray

Complete blood count (CBC)

Pulmonary function tests (PFTs)

Electrocardiogram (ECG)

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

A) Incorrect. While heart failure can occur in severe cases of COPD, it is not the primary reason for the progression of the condition.

B) Correct. The progressive nature of COPD is mainly attributed to the loss of lung elasticity and airflow limitation over time.

C) Incorrect. While infections can exacerbate COPD symptoms, they are not the primary cause of disease progression.

D) Incorrect. An increase in lung capacity is not a characteristic of COPD progression; it typically involves reduced lung function.

A. Taking short, shallow breaths during activities to prevent fatigue B. Performing all daily activities at once to conserve energy for rest C. Using assistive devices to complete all tasks independently D. Prioritizing activities and taking rest breaks as needed

Correct Answer is D

Explanation

A) Incorrect. Taking short, shallow breaths can lead to inadequate oxygenation and increased fatigue. Deep and controlled breaths are preferred.

B) Incorrect. Performing all activities at once can lead to excessive fatigue. Energy conservation involves pacing activities and taking rest breaks.

C) Incorrect. While assistive devices can be helpful, relying solely on them without considering energy conservation principles may not be effective.

D) Correct. Prioritizing activities and taking rest breaks as needed are key components of energy conservation for individuals with COPD.
