Which of these statements about the heart are true?

It has two atrial and two ventricular chambers. It pumps oxygenated blood to all parts of the body. It plays a role in tissue oxygenation

Match the layers of cardiac muscles with their positions within the heart.

Myocardium- Middle Layer Epicardium- Outermost Endocardium-Innermost

Which of these organs are parts of the upper respiratory tract?

Nose, nasal cavity Sinuses, pharynx

The process of exhalation involves:

Intraalveolar pressure rising above atmospheric pressure.

A nursing student is preparing to teach a patient how blood flows through the heart. In what order would the student place these steps to describe the process?

Deoxygenated blood returns to the right atrium via the superior and inferior vena cava. It passes through the tricuspid valve to the right ventricle. From the right ventricle, the blood moves to the pulmonary artery and into the lungs, where gas exchange

A patient with weak right ventricular systole asks what is wrong with his heart. What should the nurse say?

“The right side of your heart is not pumping with enough force to propel an adequate amount of blood to the lungs.”

Following damage to the epicardium, the nurse would expect which changes to occur in the heart wall?

Impaired secretion of serous fluid Increased friction during heart contractions

A patient with a chronic respiratory disease is to receive teaching about the breathing process. Information to include is that ventilation starts with inspiration and is triggered by

Impulses in the respiratory center of the brain

During the inspiratory phase of respiration, the phrenic nerve:

Stimulates the diaphragm to move downward

A nursing student is preparing to teach a patient the process of inspiration and expiration. In what order would the student place these steps to describe the process?

The respiratory center in the brain releases an impulse to nerves. The phrenic nerve stimulates the diaphragm to move downward and the intercostal nerve causes the intercostal muscles to contract. The chest cavity expands, causing decreased intraalveola
