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.

Which of the following most accurately describes the process that must occur when working with research animals covered by U.S.
kondor19780726 [428]

Answer:

The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval

Explanation:

Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.
