Each of the following pregnant women is scheduled for a 14-week antepartal visit.In planning care, the nurse would give priority teaching on Quad screening to which client?

Choice A rationale

50% of the offspring have a chance of developing the disease from the affected parent. Autosomal dominant inheritance means that a single copy of the altered gene in each cell is sufficient to cause the disorder. Thus, each child of an affected parent has a 50% chance of inheriting the condition.

Choice B rationale

Diseases transmitted from a carrier mother to her son typically describe X-linked recessive inheritance, not autosomal dominant. In autosomal dominant conditions, both males and females can be affected, and it doesn't depend on the sex of the parent transmitting the gene.

Choice C rationale

All of the offspring will develop the disease is incorrect. In autosomal dominant inheritance, there is a 50% chance of passing the altered gene to the offspring, not 100%.

Choice D rationale

50% of the offspring will be carriers of the disease from the affected parent is incorrect for autosomal dominant inheritance. There are no "carriers" in autosomal dominant diseases; individuals either have the disease or they don't, based on whether they inherit the altered gene.

Choice A rationale

Rubella vaccination is contraindicated during pregnancy due to the risk of congenital rubella syndrome in the fetus. It should be administered postpartum if the client is non-immune.

Choice B rationale

Preterm labor is a concern at 28 weeks' gestation. Educating the client on signs and symptoms can help in early detection and management, potentially improving outcomes for both mother and baby.

Choice C rationale

Rh-negative mothers with a negative antibody screen should receive Rhogam at 28 weeks to prevent Rh sensitization. This is crucial to avoid hemolytic disease of the newborn in future pregnancies.

Choice D rationale

A positive urine analysis for leukocytes indicates a possible urinary tract infection. A clean catch urine culture is needed to identify the causative organism and guide appropriate antibiotic therapy.

Choice E rationale

The glucose challenge test result of 120 at 26 weeks is within normal limits, but a 3-hour diagnostic glucose tolerance test may be ordered if there's a high index of suspicion for gestational diabetes or other risk factors.

Choice F rationale

A blood transfusion is not indicated as the hemoglobin/hematocrit levels (11.0 mg/dl and 35%) are within acceptable limits for pregnancy.
