Final answer:

The dose rate for a patient who received 2000 mrad during a 10-minute fluoroscopic examination is 0.2 rad/min after converting mrad to rad and dividing by the time.

Step-by-step explanation:

If a patient received 2000 mrad during a 10-minute fluoroscopic examination, the dose rate can be calculated by dividing the total dose by the time. The dose rate is the amount of radiation received per unit time and is usually expressed in rad/min or Gy/s.

Firstly, we should convert millirad (mrad) to rad, knowing that 1 rad = 1000 mrad:

  • 2000 mrad = 2 rad

Now, we divide the total dose by the time to find the dose rate:

  • 2 rad / 10 min = 0.2 rad/min

Therefore, the dose rate was 0.2 rad/min.
