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:
A. Second and third trimesters insulin needs increase because the placenta is fully developed.
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 are prone to hyperglycemia at all times during the first trimester because they are consuming more simple sugar.
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 are never modified during pregnancies.
Maternal insulin requirements often increase during pregnancy due to increased insulin resistance.
D. Insulin crosses the placenta to the fetus only in the first trimester, after which the fetus secretes its own.
Insulin crosses the placenta throughout pregnancy, and the fetus does not secrete its own insulin until after birth.

A nurse is caring for a client who is at 39 weeks of gestation and is in active labor.
The nurse locates the fetal heart tones above the client's umbilicus, at the midline. The nurse should suspect that the fetus is in which of the following presentation?
A. Posterior
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. Breech
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. Cephalic
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. Oblique.
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. Transverse
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 woman is undergoing a nipple-stimulated contraction stress test (CST). She is having contractions that occur every 3 minutes (3/10). The fetal heart rate (FHR) has a baseline of approximately 130 beats/min with the decelerations happening after the mother's contractions, Nadirs happening at the end of the uterine contractions. The interpretation of this test is said to be
Select one:
A. Positive
A positive CST indicates late decelerations that persist in more than 50% of the contractions, which is not the case in this scenario.
B. Negative
A negative CST indicates the absence of late decelerations, which is not the case in this scenario.
C. Satisfactory
A satisfactory CST indicates that there are no late decelerations, and the test is considered normal.
D. Reactive
Reactive is not a term used to interpret a CST.
E. Reactive
