Metabolic changes throughout pregnancy that affect glucose and insulin in the mother and the fetus are complicated but important to understand. Nurses should know that
 
  a. Insulin crosses the placenta to the fetus only in the first trimester, after which the
  fetus secretes its own.
  b. Women with insulin-dependent diabetes are prone to hyperglycemia during the
  first trimester, because they are consuming more sugar.
  c. During the second and third trimesters, pregnancy exerts a diabetogenic effect that
  ensures an abundant supply of glucose for the fetus.
  d. Maternal insulin requirements steadily decline during pregnancy.

Question 2

The nurse is caring for a 2-year-old patient admitted with suspected respiratory syncytial virus (RSV). The nurse anticipates that the provider will order a throat culture to confirm the diagnosis. Is this statement true or false?
 
  Indicate whether the statement is true or false

Answer to Question 1

C
Feedback
A Insulin never crosses the placenta; the fetus starts making its own around the
tenth week.
B As a result of normal metabolic changes during pregnancy, insulin-dependent
women are prone to hypoglycemia (low levels).
C Pregnant women develop increased insulin resistance during the second and third
trimesters.
D Maternal insulin requirements may double or quadruple by the end of pregnancy.

Answer to Question 2

F
A sputum specimen is necessary to rule out other diagnoses such as influenza or
pneumonia. Because younger children can seldom produce a deep cough on command and
often swallow secretions, obtaining specimens often requires nasal washing. Throat
cultures are used to identify the causative agents for either a sore throat or tonsillitis.
