Final answer:
The best nursing response to a client relieved after a TIA is to affirm that it is a serious warning sign and discuss ways to lower stroke risks.
Step-by-step explanation:
The appropriate nursing response to a client who has experienced an initial transient ischemic attack (TIA) and indicates relief that it wasn't serious would be: "TIA is a warning sign. Let's talk about lowering your risks." This statement acknowledges the patient's relief while emphasizing the importance of recognizing a TIA as a serious event. A TIA is a short-term event, often called a mini-stroke, characterized by a temporary loss of neurological function due to a disruption of blood flow to the brain, which resolves within 24 hours. It is indeed a warning sign that could indicate a higher risk for a full stroke. Therefore, it is important to discuss ways to reduce stroke risk following a TIA by addressing modifiable risk factors such as hypertension, smoking, and high cholesterol.
