A nurse is teaching a health class about the heart. Which information from the class members indicates teaching by the nurse is successful for the flow of blood through the heart, starting in the right atrium?

Left atrium, right ventricle, left ventricle

Left atrium, left ventricle, right ventricle

Right ventricle, left atrium, left ventricle

Right ventricle, left ventricle, left atrium

Answer and Explanation

The Correct Answer is A

A. Blood flow starts from the right atrium, moves into the right ventricle, then to the lungs, where it is oxygenated and returns to the left atrium, and then flows into the left ventricle before being pumped into the aorta.
B. This sequence incorrectly places the left atrium before the right ventricle, which is not the correct flow of blood.
C. This sequence starts incorrectly with the right ventricle, skipping the left atrium entirely after blood is oxygenated.
D. This option also incorrectly starts with the right ventricle and does not include the proper sequence of blood flow.

B. Assessing handwashing techniques is crucial, as proper hand hygiene is a fundamental way to prevent infections.
C. Understanding the patient's perception of infection risk in their home environment can highlight potential areas for intervention.

A. A patient with hypercapnia wearing an oxygen mask B. A patient with a chest tube ambulating with the chest tube unclamped C. A patient with thick secretions being tracheal suctioned first and then orally D. A patient with a new tracheostomy and tracheostomy obturator at bedside

Correct Answer is B

Explanation

A. A patient with hypercapnia requires monitoring, but wearing an oxygen mask indicates some level of intervention is in place.
B. A patient with a chest tube should never ambulate with the chest tube unclamped, as this can lead to a collapsed lung and respiratory distress; thus, this patient should be prioritized.
C. While a patient with thick secretions may need suctioning, this is not as critical as ensuring the safety of a patient with an unclamped chest tube.
D. A patient with a new tracheostomy requires monitoring, but the presence of the obturator indicates readiness for emergencies; this does not take priority over the safety of the patient with the chest tube.
