Final answer:
The response indicating a need for further teaching is that the boy can resume football practice in 2 weeks, due to the risk of injury and bleeding with thrombocytopenia. Avoiding aspirin and NSAIDs is correct, as is swimming for safe activity. Antihistamines are not generally contraindicated.
Step-by-step explanation:
The nurse is caring for a 12-year-old boy with idiopathic thrombocytopenia and is providing discharge instructions about home care and safety recommendations to the boy and his parents. Among the responses given to the nurse's instructions, the one that indicates a need for further teaching is: "He can resume football practice in 2 weeks." This is because engaging in a contact sport like football could pose a significant risk to a child with a condition that causes easy bruising and bleeding due to the low platelet count characteristic of thrombocytopenia.
It is correct that the child should avoid aspirin and NSAIDs as these can further inhibit the function of platelets, increasing the risk of bleeding. Swimming is suggested as a great non-contact physical activity that is generally safe for someone with thrombocytopenia. Taking antihistamines does not generally pose a risk for bleeding and is typically not contraindicated for thrombocytopenia unless the specific medication has known interactions or side effects that are relevant to this condition.
Therefore, the parents' statement about resuming football practice too soon after discharge is the one that indicates a misunderstanding of the safety guidelines and the need for additional instruction from the healthcare provider.
