The parents of a child with sickle cell anemia are concerned about subsequent
children having the disease. Which response by the nurse is most accurate?
"Sickle cell anemia is not inherited."
"All siblings will have sickle cell anemia."
"There is a 25% chance of a sibling having sickle cell anemia."
"There is a 50% chance of a sibling having sickle cell anemia." ✔️Ans -
"There is a 25% chance of a sibling having SCA."
SCA is inherited as an autosomal recessive disorder. In this inheritance
pattern, there is a 25% chance that each subsequent child will have the
disorder
A 2-month-old formula-fed baby is brought in for a routine checkup. The
parent of the baby tells the nurse that a friend has advised her to give fresh
cow's milk to the baby instead of formula milk because it has high nutritional
value. What is the nurse's best response?
Fresh cow's milk is the best source of nutrition for a 2-month-old baby.
The mother can start giving cow's milk to her baby at 3 months of age.
Cow's milk should be avoided before 12 months of age, because it may cause
sickle cell anemia.
Cow's milk should be avoided before 12 months of age, because it may cause
iron-deficiency anemia. ✔️Ans - Cow's milk should be avoided before 12
months of age, because it may cause iron-deficiency anemia.
,It is important for a nurse to educate the parents about appropriate measures
to be taken to prevent iron-deficiency anemia. Fresh cow's milk contains a
heat-labile protein that can induce gastrointestinal bleeding in children
younger than 12 months. It can also cause gastrointestinal mucosal damage in
these children, leading to bleeding. Therefore, fresh cow's milk should not be
given to children before 12 months of age, because it may cause iron-
deficiency anemia due to gastrointestinal bleeding. Sickle cell anemia is not
caused by cow's milk; instead it is an inherited genetic disease.
