Answer:
The correct answer will be option-A.
Explanation:
The cardiac cycle of the heart is divided into two phases: contraction (systole) and relaxation (diastole).
The atria and ventricles of the heart contract simultaneously in response to the impulse generated in the SA node. The contraction of the atria and ventricles push the blood or pumps the blood.
The atrial systole pumps blood to ventricles whereas the ventricular systole pumps blood to the body parts.
Thus, option-A is the correct answer.
The nursing intervention that the nurse would implement for a forgetful, disoriented client who has Alzheimer's disease is to control the patient's unsafe behaviors.
<h3>What is Alzheimer's disease?</h3>
Alzheimer's disease is a neurodegenerative disease characterized to have problems in motor conditions and loss of the memory, which requires important healthcare in and advanced state of the disease.

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.
The best category for each medical term are:
- PET scan (for positron emission tomography)- diagnostic tool.
- An electrocardiogram -diagnostic tool.
- Gunther’s disease - disorder.
<h3>What are electrocardiogram?</h3>
An electrocardiogram (ECG) is known to be a kind of a test that can be used to be able to examine a person's heart's rhythm as well as their electrical activity.
Note that it is one that has Sensors attached to the human skin and this is said to be used to know the electrical signals made by the heart each time it said to beats.
A PET scan is known to be a kind of an effective way to help know a lot of conditions such as cancer, heart disease and others.
Therefore, The best category for each medical term are:
- PET scan (for positron emission tomography)- diagnostic tool.
- An electrocardiogram -diagnostic tool.
- Gunther’s disease - disorder.
