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
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. When part of the lung is obstructed or collapsed: This statement is accurate. Unequal chest expansion can occur when part of the lung is obstructed or collapsed, preventing the affected area from expanding normally during inhalation.
B. When bulging of the intercostal spaces is present: This statement is not accurate. Unequal chest expansion typically refers to decreased expansion on one side, not bulging of intercostal spaces.
C. In an obese patient: This statement is not accurate. Obesity can affect breathing patterns and lung function, but it is not the primary cause of unequal chest expansion.
D. When accessory muscles are used to augment respiratory effort: This statement is not accurate. The use of accessory muscles to augment respiratory effort can be a sign of respiratory distress, but it doesn't directly cause unequal chest expansion. Unequal expansion is more indicative of specific lung conditions or issues with lung mechanics.
Correct Answer is D
Explanation
A. Perform the confrontation test:
The confrontation test is a basic visual field screening test. It assesses the peripheral vision by having the patient cover one eye and the examiner covers the opposite eye. The patient and the examiner then bring their fingers into the visual field from the periphery, and the patient indicates when they see the fingers.
B. Ask the patient to read the print on a handheld Jaeger card:
Jaeger cards are used for near vision testing. The patient reads progressively smaller print to assess their near vision acuity.
C. Determine the patient's ability to read newsprint at a distance of 12 to 14 inches:
This method assesses near vision. It is often used informally in clinical settings, where the patient is asked to read a newspaper or similar print at a comfortable reading distance.
D. Use the Snellen chart positioned 20 feet away from the patient:
The Snellen chart is a standardized chart used for visual acuity testing. It is placed 20 feet away from the patient, and the patient is asked to read the letters or symbols on the chart with one eye covered at a time.
