A nurse in a clinic is teaching the mother of a 4-month-old infant who has been breastfed. The mother plans to switch her infant to an iron-fortified formula. Which of the following should be included in the teaching?

Iron is poorly absorbed in infants.

Iron facilitates growth of bones in infants.

Iron stores in infants begin to deplete.

Iron facilitates development of vision in infants.

Answer and Explanation

The Correct Answer is C

Choice A Reason:
Iron is not poorly absorbed in infants; in fact, infants absorb iron quite efficiently. Breast milk contains a small amount of iron, but it is highly bioavailable and well-absorbed. When switching to formula, it is important to use iron-fortified options to prevent iron deficiency anemia.

Choice B Reason:
While iron is essential for overall growth and development, including bone growth, it is not the primary reason for emphasizing iron in infant nutrition. The key concern with iron, especially when transitioning from breastfeeding, is the prevention of iron deficiency anemia, which can affect cognitive and motor development.

Choice C Reason:
This is the correct information to include in the teaching. Infants are born with a reserve of iron that begins to deplete around 4 to 6 months of age. It is crucial to introduce iron-fortified formula at this time to ensure the infant continues to receive adequate iron for development and to prevent iron deficiency anemia.

Choice D Reason:
Iron does play a role in the development of the nervous system, which can indirectly affect vision, but it is not specifically known for facilitating the development of vision in infants. The primary concern with iron intake in infants relates to its role in preventing anemia and supporting overall growth and development.

Correct Answer is B

Explanation

Choice A reason:
Type 1 diabetes mellitus is generally not directly associated with maternal smoking. It is an autoimmune condition where the pancreas produces little to no insulin. Risk factors for Type 1 diabetes include family history and possibly environmental factors, but maternal smoking is not a recognized risk factor.

Choice B reason:
Intrauterine growth restriction (IUGR) refers to poor growth of a fetus while in the mother's womb during pregnancy. The causes of IUGR are many, but maternal smoking is a well-documented risk factor. Smoking during pregnancy can reduce oxygen and nutrient delivery to the fetus, leading to low birth weight and other complications.

Choice C reason:
While smoking during pregnancy can increase the risk of various health issues, there is no direct and consistent evidence linking it to hearing loss in newborns. Hearing loss in newborns can be due to genetic factors, infections during pregnancy, or complications at birth.

Choice D reason:
Congenital heart defects are the most common type of birth defect, and their causes can be multifactorial, including genetic and environmental factors. Maternal smoking has been associated with an increased risk of certain congenital heart defects, but the relationship is not as strong as with intrauterine growth restriction.

A. Initiation of pushing B. Preparation for cesarean birth C. Magnesium sulfate infusion D. Examination to determine cervical status

Correct Answer is B

Explanation

Choice A reason:
Initiating pushing in a client with suspected placenta previa is contraindicated. Placenta previa is a condition where the placenta covers the cervix, and pushing could lead to severe bleeding and compromise both the mother and the fetus. The normal labor process involves pushing only after full cervical dilation, and in the case of placenta previa, this could exacerbate the condition.

Choice B reason:
Preparation for cesarean birth is the correct action when placenta previa is suspected. With placenta previa, vaginal delivery could cause significant hemorrhage due to the placenta's position over the cervical opening. A cesarean birth bypasses the cervix, thereby avoiding disruption of the placenta and preventing excessive bleeding.

Choice C reason:
Magnesium sulfate is used in obstetrics to prevent seizures in preeclampsia and to delay preterm labor, not for placenta previa. While it is important to manage the client's overall condition, magnesium sulfate would not address the immediate concern of potential hemorrhage due to placenta previa.

Choice D reason:
An examination to determine cervical status in the presence of placenta previa should be avoided unless absolutely necessary and performed under controlled conditions, such as in an operating room where a cesarean delivery can be performed if needed. Digital cervical examinations can dislodge the placenta and cause bleeding.
