You have just delivered a premature baby. Your assessment reveals that he is breathing adequately; however, his heart rate is 90
s2008m [1.1K]

Answer:

The answer is letter B, keep him warm and ventilate with BVM.

Explanation:

In order to know more about the answer, let's check out the meaning of "Premature Baby" first.

Premature Baby- a baby born through premature birth <em>(fewer than 37 weeks).</em>  Babies are normally born at the usual <em>40 weeks.</em> Health problems may occur with premature babies, thus it is very important to monitor them.  

In the situation above, the premature baby's heart rate is only 90 beats/min. <em>A resting heart rate for a newborn infant is 130-150 beats per minute. </em>This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). <u><em>An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate. </em></u>

<u><em>Remember: </em></u>Inhalation increases the heart rate.
