A woman who is 20 weeks pregnant has been taught about fetal development.. My baby’s about 7 ½ inches long
A woman who is 20 weeks pregnant has been taught about fetal development. Which of the following statements, if made by her, indicate that she has correctly understood what has been taught?
a. My baby is able to breathe now
b. My baby can open his eyes
c. My baby’s about 7 ½ inches long
d. My baby’s starting to grow fingernails
Answer C. By 20 weeks gestation the fetus is approximately 10 cm long or 7 ½ inches. Fetal lungs do not begin the movements of respiration until 24 weeks. Because oxygen is provided through the placenta, the function of the lungs for breathing does not occur until birth. The fetus can open its eyes at 28 weeks gestation. Fingernails begin to grow at 10 weeks gestation but are not complete until 38 weeks.
