Question

A nurse provides instructions to a client who is scheduled for a radioactive iodine uptake test. Which statement by the client indicates a need for further instructions?

a) the test measures the rate of iodine uptake by my thyroid gland
b) I will need to drink a small dose of radioactive iodine before the test
c) a 24 hour urine specimen will need to be collected to measure iodine excretion
d) I need to minimize close contact with others in my family for a period of 48 hours after the test because of the radioactivity in my system

Answer 1

The correct statement indicating a need for further instructions is b) I will need to drink a small dose of radioactive iodine before the test.

Step-by-step explanation:

The correct statement indicating a need for further instructions is b) I will need to drink a small dose of radioactive iodine before the test. This statement is incorrect because the radioactive iodine is not ingested before the test, but rather administered intravenously or through a small capsule. The purpose of the test is to measure the rate of iodine uptake by the thyroid gland, as mentioned in statement a. Statement c is also correct as a 24-hour urine specimen is collected to measure iodine excretion. Statement d is also correct as the client should minimize close contact with others due to the radioactivity in their system after the test.
