The nurse is caring for an infant who has frequent respiratory infections. while assessing the infant, the nurse hears a loud and harsh holosystolic murmur at the left lower sternal border. what should the nurse infer from these findings?

The nurse should infer base from the findings is that the infant is having a ventricular septal defect in which cause the infant having to produce a loud and harsh holosystolic murmur that is found in the left lower sternal border.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
