Answer to Question 1

ANS: C
Phenylketonuria is an inborn error of metabolism caused by a deficiency or absence of the enzyme needed to metabolize the essential amino acid phenylalanine. Individuals with this disorder can metabolize glucose. Thyroxine is one of the principal hormones secreted by the thyroid gland. Phenylketones are metabolites of phenylalanine excreted in the urine.

Answer to Question 2

ANS: B
When the cervix is completely dilated, the head can descend through the pelvis and stimulate the Ferguson, or pushing, reflex. Cervical dilation must first be confirmed because premature pushing efforts may result in cervical edema and corresponding delay in dilation. Once complete dilation has been confirmed, the nurse can notify the health care provider. Teaching positioning and pushing efforts is accomplished once complete dilation has been confirmed.
