1. Which is true about women who experience hyperemesis gravidarum?

1. Seventy percent of all pregnant women suffer from it at some point in pregnancy.

2. Such women have vomiting severe and persistent enough to cause weight loss,

   dehydration, and electrolyte imbalance.

3. They need intravenous (IV) fluid and nutrition for most of their pregnancy.

4. They often inspire similar, milder symptoms in their male partners and mothers.

ANS: 2 \n Women with hyperemesis gravidarum have severe vomiting; however, treatment for several days sets things right in most cases. Although 70% of pregnant women experience nausea and vomiting, about 0.5 to 2% proceed to this severe level. IV administration may be used at first to restore fluid levels, but it is seldom needed for very long. Women suffering from this condition want sympathy, because some authorities believe that difficult relationships with mothers or partners may be the cause.

Infants should be breastfed as soon as possible after birth and at least __ to ? times per day thereafter.

Underweight women should gain 12.5 to 18 kg.

Adolescents are encouraged to strive for weight gains at the upper end of the recommended scale.

Normal-weight women should gain 11.5 to 16 kg.

A BMI of 22 represents a normal weight. Therefore, a total weight gain for pregnancy would be about 11.5 to 16 kg, or about 1 to 2.25 kg in the first trimester and about 500 g/week during the second and third trimesters,

Both normal-weight and underweight women with inadequate weight gain have an increased risk of giving birth to an infant with

intrauterine growth restriction (is when a baby in the womb (a fetus) does not grow as expected. The baby is not as big as would be expected for the stage of the mother's pregnancy.)
