You are the nurse providing prenatal education to a group of pregnant teenagers. one of the group members asks you to talk about how the baby develops after the first trimester. an accurate statement from you about the fetal stage would be which of the following? a. the heartbeat can be heardb. bones are completely ossifiedc. embryo no longer vulnerable to toxinsd. no kidney function happens before birth

A. The heartbeat can be heard

Explanation:

After the first trimester, during the fourth month, the heartbeat of the fetus becomes loud enough to be heard with the help of a stethoscope placed on the abdomen of the mother.

From fifth to the seventh month of the development, kicks and jabs are felt by the mother as the fetal legs grow and develops. Languo, a wrinkled pink colored skin covers the fetus.

Languo is in turn covered with a white greasy substance called vernix caseosa.

From eighth to ninth months, rotation of the fetus places its head pointing towards the cervix to facilitate childbirth later.

The development of testes takes place in the seventh month while the body hairs become disappeared in the eighth month.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
