A53-year old woman collapses while gardening. she is unresponsive, is not breathing, and does not have a pulse. a neighbor, who is an emergency medical technician, rushes to her with an aed. question: after the aed pads are attached to the victims bare chest, the aed detects a ventricular fibrillation what is the next step when using the aed?

The next step would be to follow the AED prompts.

An AED or Automated External Defibrillator refers to a lightweight, small apparatus, which evaluates an individual's heart rhythm and can determine the irregular heart rhythms, like VF (ventricular fibrillation) or VT (ventricular tachycardia), also called Sudden Cardiac Arrest.

Automated external defibrillators can assist in saving many lives at the time of sudden cardiac arrest. However, even after training, memorizing the steps to use an AED in the right manner can be tough.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
