Schedule exams, when ever possible, in the morning.
Get a good nights rest the night before the exam.
Allow sufficient time to arrive and relax before the exam.
Fasting for blood tests should be 12 hours when possible.
No alcohol for 24 hours prior to the examination.
No non-prescribed (over the counter) drugs for 24 hours prior to the exam.
Avoid caffeinated beverages (coffee, tea, soft drinks) prior to the exam.
Avoid tobacco (might raise blood pressure) 3 hours prior to the exam.
Avoid strenuous exercise 24 hours prior to the exam.
When voiding a urine specimen make sure it is not the first specimen of the day.
If your client has large or muscular arms, make sure a wide arm cuff is used when the blood pressure is taken.
If the first blood pressure reading is elevated, have your client take some relaxing deep breaths before the next reading.
