For each potential prescription from the provider, click to specify if the potential prescription is anticipated, nonessential, or contraindicated for the client.

Choice A rationale

Chromosomal defects are typically assessed using different tests, such as chorionic villus sampling or amniocentesis, rather than an ultrasound at this early stage.

Choice B rationale

Fetal lung maturity cannot be assessed at 9 weeks gestation because the lungs are not yet developed. This assessment is usually done later in pregnancy if preterm delivery is anticipated.

Choice C rationale

At 9 weeks gestation, the primary purpose of an ultrasound is to confirm the presence of a fetal heartbeat, which indicates a viable pregnancy.

Choice D rationale

The position of the fetus in utero is not a concern at this early stage of pregnancy. Fetal positioning becomes relevant later in pregnancy, closer to delivery.

Choice A rationale

Iron needs significantly increase during pregnancy to support the increased blood volume, the formation of the placenta, and the growth of the fetus. Pregnant women often require additional iron to prevent anemia and ensure adequate oxygen transport to the baby.

Choice B rationale

While calcium requirements do increase during breastfeeding to support milk production, this statement is not directly related to the nutritional needs during pregnancy. The focus during pregnancy should be on adequate intake of nutrients that support both maternal and fetal health.

Choice C rationale

Vitamin E requirements do not decline during pregnancy. In fact, the need for antioxidants like vitamin E may increase to protect both the mother and developing fetus from oxidative stress.

Choice D rationale

While prenatal vitamins are important for meeting various nutritional needs during pregnancy, they do not always provide sufficient vitamin D. Some women may need additional supplementation based on their dietary intake, sun exposure, and individual health needs.
