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
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.

Correct Answer is B
Explanation
A. While anxiety may contribute to hyperventilation, in the context of a febrile child, the primary factor is usually metabolic.
B. Increased metabolic demands due to fever can elevate the body’s oxygen requirements, prompting hyperventilation as a compensatory mechanism.
C. Decreased drive to breathe would not lead to hyperventilation; rather, it might result in hypoventilation or respiratory distress.
D. Infection destroying lung tissues would typically lead to respiratory distress or failure, not directly cause hyperventilation without the context of increased metabolic needs.
Correct Answer is ["A","C","D","E"]
Explanation
A. Communication signs for airborne precautions are necessary to inform staff and visitors about the required precautions for TB, which is spread via airborne transmission.
B. A surgical mask is not adequate for TB; instead, an N95 respirator is required to filter out the airborne particles effectively.
C. The N95 respirator, gown, gloves, and eyewear are essential personal protective equipment for caring for a patient with tuberculosis. The N95 respirator specifically protects against inhaling infectious particles.
D. Negative-pressure airflow in the room is critical for tuberculosis patients to prevent airborne contaminants from spreading to other areas of the facility.
E. A private room is required to isolate the patient and reduce the risk of transmission to other patients and staff.
F. A communication sign for droplet precautions is not applicable as tuberculosis is primarily transmitted via airborne routes, not droplet transmission.
