A nurse is assisting with the care of a client who is at 30 weeks of gestation and has tuberculosis. Which of the following actions should the nurse take?

A. Hyperbilirubinemia: Hyperbilirubinemia in neonates is commonly due to immature liver function and the breakdown of red blood cells after birth. It is not linked to maternal folic acid deficiency and would not be prevented through maternal folic acid supplementation.

B. Hyperemesis gravidarum: Hyperemesis gravidarum is a severe form of nausea and vomiting that occurs during pregnancy, affecting the mother rather than the neonate. Folic acid supplementation does not prevent this condition, as it is more related to hormonal changes during pregnancy.

C. Iron deficiency anemia: Iron deficiency anemia occurs when there is an inadequate amount of iron, not folic acid, in the mother’s or infant’s diet. While iron is important during pregnancy for both the mother and the developing fetus, folic acid deficiency primarily affects neural tube development, not iron levels or red blood cell production in the same way. Iron supplementation is recommended during pregnancy to prevent iron deficiency anemia.

D. Neural tube defects: Neural tube defects, such as spina bifida and anencephaly, are directly linked to folic acid deficiency during early pregnancy. Adequate folic acid intake before conception and during early pregnancy significantly reduces the risk of these serious birth defects affecting the brain and spine.

A. Provide a surgical mask for the client's partner during visits: While it is important to protect visitors, providing only a surgical mask is insufficient for tuberculosis precautions. Airborne infections like TB require specialized respirators (such as N95 masks), not just standard surgical masks.

B. Initiate airborne precautions for the client: Tuberculosis is an airborne disease, meaning the client must be placed on airborne precautions. This includes placing the client in a negative pressure room and requiring anyone entering to wear an N95 respirator to prevent transmission.

C. Tell the client that a cesarean birth is necessary: Having tuberculosis does not automatically necessitate a cesarean delivery. If the TB is well controlled and the client is noninfectious by the time of labor, vaginal birth is typically safe.

D. Administer penicillin G to the client immediately: Penicillin G is used to treat infections such as syphilis, not tuberculosis. TB requires a specific antibiotic regimen (such as isoniazid, rifampin, ethambutol, and pyrazinamide), not penicillin.
