In the conduction system of the heart, which of the following components is stimulated after the sinoatrial node?
Left bundle branch
Purkinje fibers
Right bundle branch
Atrioventricular node
The Correct Answer is D
A. Left bundle branch: The left bundle branch is stimulated after the atrioventricular node and bundle of His, not immediately after the sinoatrial node.
B. Purkinje fibers: The Purkinje fibers are stimulated later in the conduction pathway, after the bundle branches.
C. Right bundle branch: The right bundle branch is also stimulated after the atrioventricular node and bundle of His.
D. Atrioventricular node: After the sinoatrial node initiates the heartbeat, the electrical impulse travels to the atrioventricular node, which then passes the signal to the bundle of His and down to the bundle branches.

Explanation
A. Fire extinguishers' pins are intact: Ensuring that fire extinguishers are properly maintained, including checking that the pins are intact, is essential for fire safety preparedness.
B. Multiplug adapters are not in use: While using multiplug adapters can be a safety concern, it is not directly related to fire preparedness.
C. Sprinkler heads are unobstructed: This is important for fire safety but is more related to fire suppression rather than the preparation aspect.
D. One emergency exit is available: Ideally, there should be multiple emergency exits; having only one is a safety concern rather than a preparedness measure.
