A 42-year-old man has fallen from a steel beam at a construction site and landed on jagged metal below. he is awake but slow to respond. his skin is pale, cool, and diaphoretic. he is able to speak, and his respirations are about 24 breaths per minute. his radial pulse is weak and rapid. he has large lacerations to his torso and lower extremities. which should you do first?

Control bleeding with direct pressure.

Explanation:

If a laceration is large and deep, is bleeding badly, or blood is blowing out violently from it (because there is a perforation in an artery) it is possible that it won't stop bleeding. In the case of this worker, you should apply pressure in his wounds in his torso, raise his lower extremities and apply pressure on them too, to immediately call 911.

explanation:

kinetic and potential energies would be types of mechanical energies.
