Study Questions and Answers
Q1 After which of the following procedures should a patient's body fluids be considered radioactive?
A A nuclear medicine procedure
Q2 After a patient has received therapeutic iodine 131 and returned to her room:
A You should treat all objects in her room as potentially contaminated. I-131 is an unsealed source, and may be
present in any of the patient's secretions or excretions. Therefore, you should treat all objects in the room as
potentially contaminated, and handle them only with gloves.
Q3 Which of the following is a source of radiation in the healthcare setting?
A Nuclear medicine Radiation used to diagnose or treat disease can be divided into four categories: unsealed source
radiation, brachytherapy, nuclear medicine, and external beam radiation.
Q4 A patient has an unsealed source radiation procedure. Which of the following statements is true?
A After the procedure, the patient's leftover lunch should be considered radioactive. These procedures use high doses
of radiation. It travels all through the patient's body. All of the objects in the patient's room should be considered
radioactive.
Q5 Which of the following involves external beam radiation?
A Fluoroscopy Fluoroscopy is an external beam procedure.
Q6 Which of the following is a safe and appropriate way to handle radioactive materials?
A Using a certified chemical fume hood when preparing tracers Use a chemical fume hood certified for radioactive
materials when preparing tracers or other radiopharmaceuticals.
Q7 A patient is receiving external beam radiation. You are assisting. Choose the true statement.
A You are at risk of radiation exposure from both the primary beam and scattered secondary beams. The highest dose
of radiation comes from the primary beam. Secondary beams also may scatter off the patient's body and strike
nearby caregivers.
Q8 Tracers used in nuclear medicine have short half-lives. This means that:
