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.
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 C
Explanation
Choice a reason:
While there is always a risk of introducing infection with an internal examination, this is not the primary concern with placenta previa. Infections are a risk with any invasive procedure, but the precautions taken during a typical internal examination minimize this risk.
Choice b reason:
Initiating preterm labor is a concern with any manipulation of the cervix or uterus during pregnancy. However, at 37 weeks, the pregnancy is considered early-term, and the risk of preterm labor is not the primary concern in the context of placenta previa.
Choice c reason:
The primary reason for avoiding an internal examination in a client with placenta previa is the risk of profound bleeding. With placenta previa, the placenta covers part or all of the cervix. An internal examination could disturb the placenta and lead to significant hemorrhage, which can be life-threatening for both the mother and the fetus.
Choice d reason:
While there is a risk of rupturing the membranes during an internal examination, this is not the primary concern with placenta previa. The main issue is the potential for causing significant bleeding due to the placenta's location over the cervix.
Correct Answer is A
Explanation
Choice A reason: The indirect Coombs test is used to screen for antibodies in the mother's blood that could potentially cause hemolytic disease in the newborn if they are Rh-positive. A positive result indicates that the mother has developed antibodies that could cross the placenta and attack the red blood cells of an Rh-positive fetus.
Choice B reason: The indirect Coombs test does not detect Rh-negative antibodies in the newborn's blood. Instead, it is used to detect antibodies in the mother's blood. The direct Coombs test is used to detect antibodies that are already attached to the red blood cells of the newborn.
Choice C reason: The indirect Coombs test does not determine if kernicterus will occur in the newborn. Kernicterus is a form of brain damage that can result from very high levels of bilirubin in a baby's blood. It is not directly related to the presence of antibodies detected by the indirect Coombs test.
Choice D reason: The indirect Coombs test does not determine the presence of maternal antibodies in the newborn's blood. This is assessed by the direct Coombs test, which checks for antibodies bound to the surface of the newborn's red blood cells, indicating that the immune system is attacking them.
