Correct Answer is C

Explanation

A. The patient has hypotension: Hypotension does not directly cause use of accessory muscles.

B. The patient is breathing normally, using the normal muscles of inspiration and expiration: Normal breathing uses the diaphragm and intercostals, not accessory muscles like the sternocleidomastoid.

C. The patient is having difficulty breathing: Use of accessory muscles at rest indicates respiratory distress or difficulty in breathing.

D. The patient has hypertension: Hypertension is not directly related to accessory muscle use during breathing.

A. Bronchioles B. Trachea C. Pulmonary capillaries D. Lungs

Correct Answer is C

Explanation

A. Bronchioles- bronchioles are airways that lead to alveoli but are not where gas exchange occurs.

B. Trachea- this is a conduction pathway for air, not where diffusion of gases happens.

C. Pulmonary capillaries- oxygen diffuses across the alveolar membrane into the pulmonary capillaries for transport in the blood.

D. Lungs- this is too broad; gas exchange occurs specifically at the alveolar-capillary membrane.
