Question

The recommended dosage of I-131 for a test is 4.2 microcuries per kg of body weight. How many millicuries should be given to a 55 kg patient? (1 mCi = 1000 μCi) 13.8 millicuries 760 millicuries 0.23 millicuries 0.076 millicuries 230 millicuries

Answer 1

55 kg patient is 0.23 millicuries.

Step-by-step explanation:

To find the dosage in millicuries for a 55 kg patient, we need to convert the dosage from microcuries to millicuries.

Given that 1 mCi (millicurie) is equal to 1000 μCi (microcurie), we can convert the dosage as follows:

The recommended dosage is 4.2 microcuries per kg of body weight.

To find the dosage in millicuries, we divide the dosage in microcuries by 1000.

For a 55 kg patient, the dosage in millicuries would be:

[ \frac{{4.2 , \mu Ci}}{{1000}} \times 55 = 0.23 , mCi ]

Therefore, the dosage in millicuries for a 55 kg patient is 0.23 millicuries.
