The nurse is discussing the blood flow pattern of the heart. The nurse should recognize which of the following as the accurate blood flow pattern of the heart?

Aorta-Right atrium-right ventricle-pulmonary vein-lungs- pulmonary artery left atrium-left ventricle

vena cava-right atrium-right ventricle-pulmonary vein-lungs- pulmonary artery-left atrium-left ventricle

vena cava→ right atrium-right ventricle-pulmonary artery-lungs- pulmonary vein-left atrium-left ventricle

Aorta-right atrium-right ventricle-lungs-pulmonary vein-left atrium-left ventricle- vena cava

Answer and Explanation

The Correct Answer is C

In this sequence:

Vena cava brings deoxygenated blood from the body into the right atrium.

Blood flows from the right atrium to the right ventricle through the tricuspid valve.

The right ventricle pumps blood into the pulmonary artery to the lungs.

In the lungs, blood is oxygenated and returns to the heart via the pulmonary veins into the left atrium.

From the left atrium, blood moves to the left ventricle through the bicuspid (mitral) valve.

The left ventricle then pumps oxygenated blood into the body through the aorta.

This sequence represents the systemic and pulmonary circulation of the heart.

Correct Answer is A

Explanation

A. Indicates turbulent blood flow through a valve:

This statement is correct. A heart murmur is an abnormal sound during the heartbeat cycle, often indicating turbulent blood flow through a valve. Murmurs can result from various factors such as valve disorders, structural abnormalities, or other heart conditions.

B. Is an extra sound due to blood entering an inflexible chamber:

This statement is not accurate. Heart murmurs are primarily associated with turbulent blood flow rather than an extra sound related to an inflexible chamber.

C. Means that there is some inflammation around the heart:

This statement is incorrect. Heart murmurs are not specifically related to inflammation around the heart. They are primarily caused by issues with blood flow through the heart valves.

D. Is a high-pitched sound due to a narrow valve:

This statement is a bit oversimplified. While murmurs can sometimes be associated with narrow valves (stenosis), they can also result from various other valve abnormalities or conditions, and not all murmurs are high-pitched. The pitch and characteristics of a murmur can provide clues about its cause, but they are not the sole indicators.

A. Simultaneously palpating both arteries to compare amplitude. B. Listening with the diaphragm of the stethoscope to assess for bruits. C. instructing the patient to take slow deep breaths during auscultation. D. Palpating the artery at the base of the neck of the neck.

Correct Answer is B

Explanation

A. Simultaneously palpating both arteries to compare amplitude: While comparing amplitudes is important, using the diaphragm of the stethoscope to listen for bruits (abnormal whooshing sounds indicating turbulent blood flow) is a more specific and accurate method for assessing the carotid arteries for potential vascular issues.

B. Listening with the diaphragm of the stethoscope to assess for bruits: This technique allows the nurse to detect abnormal sounds (bruits) that could indicate partial blockages or stenosis in the carotid arteries, suggesting a risk of stroke or transient ischemic attack.

C. Instructing the patient to take slow deep breaths during auscultation: Deep breaths are more relevant during lung auscultation. Carotid artery assessment focuses on detecting abnormal sounds and assessing blood flow rather than respiratory patterns.

D. Palpating the artery at the base of the neck: Palpation alone does not provide enough information about potential blockages or abnormalities in the carotid arteries. Listening with a stethoscope allows for a more detailed assessment of blood flow and the presence of bruits.f the nurse hears a bruit during auscultation, they shouldnotpalpate the carotid artery. A bruit suggests partial obstruction (carotid stenosis), and compressing the artery further could worsen blood flow.
