A 56-year-old male has a blood pressure reading of 146/96mmHg. Upon hearing the reading, he exclaims, "My pressure has never been this high. Will I need to take medication to reduce it " Which of the following responses by the nurse would be best ？（）
A．"Yes. Hypertension is prevalent among males; it's fortunate we caught this during your routine examination. "
B．"We'll need to reevaluate your blood pressure because your age places you at high risk for hypertension. "
C．"A single elevated blood pressure doesn't confirm hypertension. You'll need to have your blood pressure reassessed several times before a diagnosis can be made. "
D．"You have no need to worry. Your pressure is probably elevated because you're in the doctor's office. "
参考答案：C
解析：
Hypertension is confirmed by two or more readings with systolic pressure of at least 140mmHg and diastolic pressure of at least 90mmHg. Option A is premature. Option B isn't as specific as option C and also is insensitive to the client's anxiety. Option D gives false reassurance; the client does need to have his blood pressure reevaluated.
