Correct Answer is B

Explanation

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.

A. "Pursed-lip breathing is only necessary during strenuous exercise." B. "It's a technique to increase oxygen intake." C. "Pursed-lip breathing helps to slow down breathing and improve oxygen exchange." D. "This technique is primarily used for relaxation and stress reduction."

Correct Answer is C

Explanation

A) Incorrect. Pursed-lip breathing is beneficial in various situations, not just during exercise.

B) Incorrect. While pursed-lip breathing can help with oxygenation, its primary purpose is to optimize breathing patterns.

C) Correct. Pursed-lip breathing is a technique that promotes more efficient breathing by slowing down the breath rate and enhancing oxygen exchange.

D) Incorrect. While it can have a calming effect, the primary purpose of pursed-lip breathing is to aid in respiratory function.
