You have performed a head tilt-chin lift maneuver on a 17-month-old boy and are attempting to ventilate him with a bag-valve mask. You are experiencing a lot of resistance with each breath and the chest is barely rising. Prior to attempting ventilations again, you should:

ease the head forward a little

Explanation:

Based on the information provided within the question it can be said that in this situation before attempting ventilation again, you should ease the head forward a little. This is done in order to make sure that as much air as possible is passing through the patients throat and allowing it to go into the lungs with ought any resistance, as you seem to be experiencing in this scenario.

answer; ok in rural area most people depend on private transportation(cars),pick up truck,donkey and buggy: ),and urban people can walk or ride public transportation,bus,train cab,uber.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
