Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
In emergency situations, the Assess, Recognize, and Care idea is a systematic and continuous technique for quick assessment, precise recognition, and prompt care. Because the health of an acutely ill patient can quickly deteriorate, frequent assessment, recognition, and care are essential.
<h3>What are the steps of which includes assess, recognize and care?</h3>
- Use a visual assessment to determine the need for further resources, evaluate safety, and form an initial impression of the patient
- A responsiveness check
- If the patient is not responding, open the airway while simultaneously testing for breathing and a pulse.
- After you've finished your quick assessment, give care in accordance with the circumstances discovered.
