Metabolic changes throughout pregnancy that affect glucose and insulin in the mother and the fetus are complicated but its important to understand. Nurses should understand that:

Select one:

Second and third trimesters insulin needs increase because the placenta is fully developed.

Women with insulin-dependent diabetes are prone to hyperglycemia at all times during the first trimester because they are consuming more simple sugar.

Maternal insulin requirements are never modified during pregnancies.

Insulin crosses the placenta to the fetus only in the first trimester, after which the fetus secretes its own.

Answer and Explanation

The Correct Answer is A

a.   As the placenta grows and becomes more metabolically active, it produces hormones that increase insulin resistance, leading to an increased need for insulin.
b.   Women with insulin-dependent diabetes may be prone to hyperglycemia during pregnancy, but it is not due to consuming more simple sugar.
c.   Maternal insulin requirements often increase during pregnancy due to increased insulin resistance.

d.   Insulin crosses the placenta throughout pregnancy, and the fetus does not secrete its own insulin until after birth.

Correct Answer is B

Explanation

a. A posterior presentation is when the fetus's back is toward the mother's back, and the fetal heart tones are usually heard on either side of the mother's abdomen.
b. A breech presentation is when the fetus's buttocks or feet are closest to the cervix. The fetal heart tones are usually heard above the umbilicus, at the midline, in a breech presentation.
c. A cephalic presentation is when the fetus's head is closest to the cervix, and the fetal heart tones are usually heard below the umbilicus, in either quadrant.
d. An oblique presentation is when the fetus's head or buttocks are angled toward one side of the pelvis, and the fetal heart tones are usually heard off-center, above or below the umbilicus.
e. A transverse presentation is when the fetus's spine is perpendicular to the mother's spine, and the fetal heart tones are usually heard on one side of the abdomen.

A. Inform the test as reactive. B. Tum the client onto her left side and repeat the test C. Encourage the client to walk around and repeat the test D. d Notify to the client's provider and prepare for induction of labor. E. Offer the client a snack of orange juice and repeat the test

Correct Answer is A

Explanation

a. The nonstress test is considered reactive if there are two or more accelerations of the fetal heart rate (FHR) in a 20-minute period, lasting 15 seconds or longer and peaking at least 15 beats per minute above the baseline. The FHR baseline is between 110 and 160 beats per minute, with moderate variability. The test is considered nonreactive if these criteria are not met.
b. Turning the client onto her left side is not necessary, as the test is already reactive.
c. Encouraging the client to walk around is not necessary, as the test is already reactive.
d. Notifying the client's provider and preparing for induction of labor is not necessary, as the test is already reactive.
e. Offering the client a snack of orange juice is not necessary, as the test is already reactive.
