FREE Radiography 2023 Questions and Answers
The contraction and expansion of artery walls in conjunction with vigorous contraction and relaxation of the heart is called:
Explanation:
Large arteries close to the heart and those that are further away will be affected by the powerful contractions
of the heart as it works to pump blood from the heart through their walls. This movement may be noticed
with the fingers in many places of the body and is referred to as the pulse.
Which of the following pathologic diseases would demand an increase in exposure factors?
Explanation:
Because pneumoperitoneum is an abnormal accumulation of air or gas in the peritoneal cavity, it would
necessitate a decrease in exposure variables. Obstructed gut frequently entails distended, gas-filled bowel
loops, again needing a decrease in exposure variables. With ascites, there is an abnormal accumulation of
fluid in the abdominal cavity, necessitating an increase in exposure factors.
To lessen the back strain involved with transporting patients from the stretcher to the x-ray table, you should:
Explanation:
When transporting a patient from a stretcher to an x-ray table, numerous principles apply that will help avoid
back strain. Pull, do not push the patient; pushing creates friction and makes the transfer more difficult.
Use the biceps muscles for pulling; do not bend at the waist and pull, as this motion increases back strain.
The major role of x-ray beam filtration is to:
Explanation:
It is an ethical responsibility of a radiographer to reduce radiation dose to our patients. X-rays produced
at the target comprise a heterogeneous primary beam. There are many “soft” (low-energy)photons that,
if not eliminated, would contribute to merely higher patient dose. They are too weak to penetrate the patient
and expose the image receptor; they only penetrate a tiny thickness of tissue and are absorbed. Filters,
usually constructed of aluminum, are employed in radiography to lower patient exposure by removing this
low-energy radiation, resulting in an x-ray beam of greater average energy.
If a student radiographer who is less than 18 years begins clinical duties, what is their annual dose limit?
Explanation:
According to the recommendation, the annual occupational exposure limit for students under the age of
18 is 0.1 rem (100 mrem or 1 mSv).
In which period of growth is a developing baby most radiosensitive?
Explanation:
The developing fetus is most radiosensitive during the first trimester. Very high radiation doses at this period
have the potential to result in congenital abnormalities because the fetus is going through a
significant organogenesis. Radiosensitivity generally decreases for the rest of the pregnancy.
When a patient feels as though the room is spinning around him, this is referred to as:
Explanation:
The feeling of having things swirl around you causes vertigo. It frequently occurs in conjunction with an inner-ear issue. True vertigo patients (as opposed to dizzy or lightheaded patients) are frequently extremely sick and need to be kept from falling.
