The nervous parent asks when the big "soft spot" (anterior fontanel) will be closed. The nurse's most informative response would be

A. "You can give your child acetaminophen (Tylenol) every 4-6 hours as needed for pain."

Option A is the most appropriate response because it addresses pain management, which is a common symptom in cases of tonsillitis. Acetaminophen can be used to provide relief from pain and fever, which are often associated with viral tonsillitis. However, it's important for the parent to follow the dosing instructions on the medication label and consult with their healthcare provider if they have any concerns or if the child's condition worsens.

Option B ("You will need to schedule a follow-up appointment in 2 weeks") is also not the best initial response, as it doesn't address immediate care at home for the child's comfort and pain relief.

Option C ("You will need to give your child a prescribed antibiotic for 10 days") is not the correct approach, as antibiotics do not treat viral illnesses. Viral tonsillitis is usually caused by a viral infection, and antibiotics are not effective for viral infections.

Option D ("You can place warm towels around your child's neck for comfort") can provide some comfort but is not the primary treatment for viral tonsillitis. It may help alleviate discomfort, but pain relief with acetaminophen is typically more effective.

A. Bone marrow transplantation.

Severe aplastic anemia is a condition characterized by a significant reduction in the number of blood cells produced by the bone marrow. The primary treatment for severe aplastic anemia is a bone marrow transplantation, also known as a stem cell transplant. This procedure involves replacing the patient's dysfunctional bone marrow with healthy bone marrow or stem cells from a suitable donor. This is done to restore normal blood cell production.

Option B (Exchange transfusion) is not the primary treatment for severe aplastic anemia but may be used in certain cases to manage complications or specific symptoms.

Option C (Liver transplantation) is not a treatment for severe aplastic anemia, as this condition primarily affects the bone marrow and blood cell production.

Option D (Administration of intravenous immunoglobulin) is not the primary treatment for severe aplastic anemia but may be used in some cases to manage complications, such as infections. However, it does not address the underlying cause of the disease, which is the failure of the bone marrow to produce enough blood cells.
