A child is diagnosed with sickle cell disease. The parents are unsure how their child contracted the disease. Which explanation by the nurse is the most appropriate?

Choice A reason: An elevated white blood count (WBC) is not typically a side effect of chemotherapy; in fact, chemotherapy often leads to a decreased WBC count.
Choice B reason: This is the correct choice. Bone marrow suppression is a common side effect of chemotherapy, leading to a decreased production of blood cells and necessitating precautions to prevent infection.
Choice C reason: T-cell mediated hypersensitivity is not a common side effect of chemotherapy that would dictate the type of precautions needed.
Choice D reason: Stomatitis is a possible side effect of chemotherapy, but it does not primarily determine the type of precautions required as bone marrow suppression does.

Choice A reason: Allowing parents to hold their infant is a compassionate act that acknowledges their need for closure and can help them begin the grieving process.

Choice B reason: Interviewing parents to determine the cause of the incident is not considered supportive care; it may be part of an investigation but does not provide comfort.

Choice C reason: Providing mementos can be a cherished way for parents to remember their infant and can offer some solace during a difficult time.

Choice D reason: Advising parents about the necessity of an autopsy is not supportive care; it is a medical decision that should be discussed with sensitivity to the parents' feelings and needs. Autopsies can be important for understanding SIDS and preventing future occurrences.
