Answer to Question 1
3
Rationale: Multiple medications may cause drugdrug interactions or toxicity that can cause delirium. While the older adult client is at higher risk for delirium, it is not from age-related cognitive changes. A lack of rigorous exercise will not promote delirium. Decreased social interaction can exacerbate delirium but not cause delirium.
Answer to Question 2
2
Rationale: The only known predisposing factor for the development of a communication disorder is a family history of the disorder. For stuttering, especially, family and twin studies provide strong evidence of a genetic factor in its etiology. Since family history is the only known predisposing factor, asking about impaired thermoregulation or preeclampsia is not relevant. Questioning the mother's feelings does not address the cause of the stuttering.
