Correct Answer is A
Explanation
A. Diaphragm: The diaphragm is a dome-shaped muscle that contracts and flattens during inhalation, creating negative pressure to draw air into the lungs.
B. Pectoris minor: The pectoralis minor assists with deep or labored breathing but is not the primary muscle of inhalation.
C. Pectoris major: This chest muscle plays a role in arm movement and may assist minimally in labored breathing.
D. Intercostals: The intercostal muscles assist with breathing but are secondary to the diaphragm.
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.
