A nurse is planning the discharge of an infant who has tetralogy of Fallot. The nurse anticipates the need for which of the following equipment?

A. Levothyroxine is a thyroid hormone replacement medication commonly used to treat hypothyroidism. It is not associated with teratogenic effects when used appropriately.

B. Phenytoin is an anticonvulsant medication that is known to be teratogenic, especially when used during the first trimester of pregnancy. It is associated with an increased risk of congenital malformations, such as cleft palate and heart defects, in infants born to mothers who take the medication during pregnancy.

C. Magnesium oxide is a mineral supplement commonly used to treat constipation during pregnancy. It is not associated with teratogenic effects when used appropriately.

D. Ferrous sulfate is an iron supplement commonly used to treat chronic anemia during pregnancy. It is not associated with teratogenic effects when used appropriately.

Choice A Rationale: The recommended hepatitis vaccine series does not consist of four vaccines. The Advisory Committee on Immunization Practices (ACIP) recommends a 3-dose series for most individuals, which includes doses at birth, 1-2 months, and 6-18 months.

Choice B Rationale: Hepatitis B is not typically transmitted by contaminated food. It is primarily spread through exposure to infectious blood, semen, and other body fluids. Transmission can occur through direct contact with blood or body fluids of an infected person, unprotected sex, sharing needles, or from mother to child at birth.

Choice C Rationale: While chronic hepatitis C has been associated with an increased risk of developing renal cell carcinoma, the evidence linking chronic hepatitis B with renal cell cancer is less clear. Some studies suggest a potential association, but it is not established as a common complication.

Choice D Rationale: Individuals with a history of hepatitis B or C are generally ineligible to donate blood. This is due to the risk of bloodborne transmission of these viruses. Even if the individual has recovered or been cured of hepatitis C, they are still barred from donating blood or plasma.
