How may the density be changed best on an x-ray image?
Explanation:
Radiographic density is controlled by changing the mAs. It accomplishes this by producing a large number
of x-rays.
When a patient lays flat on their back and has their head lower than their feet, what position is that?
Explanation:
Trendelenburg refers to a supine position where the patient's head is lower than their feet. The inclination
is between 15 and 30 degrees.
An intravenous injection of contrast is necessary for a patient who is having a radiologic examination. What is the creatinine normal range?
Explanation:
This is the creatinine normal range. Your creatinine levels will improve if you increase your physical activity.
Low creatinine levels are hazardous and dangerous. Lower creatinine levels can result from liver and
muscle disorders. More harmful effects may result from elevated levels. Nausea, vomiting, and elevated
blood pressure are symptoms. Kidney failure and dehydration are signs of higher creatinine levels.
REM is a unit used to measure radiation. REM stands for what?
Explanation:
The amount of radiation that humans have been exposed to is measured in REMs (Radiation Equivalent Mans).
A patient is getting a head CAT scan. The patient experiences nausea and respiratory difficulties after receiving a contrast injection. Which kind of shock is the patient going through?
Explanation:
An allergic reaction this extreme and potentially fatal is called anaphylaxis shock. An individual may have
dizziness, low blood pressure, and difficulty breathing. Epinephrine is administered intravenously to
treat anaphylaxis. Infections are the cause of septic shock. Cardiogenic shock will result from heart issues.
Your neurological system being damaged leads to neurogenic shock.
What purpose does the housing around an x-ray tube serve?
Explanation:
Radiation leakage reduction is one of the housing's main purposes. Leakage is reduced thanks to the lead
lining inside the x-ray tube. The covers for glass tubes are made of borosilicate glass. The heat inside the
tube is reduced as a result. The heat from the glass tube is not retained by the housing. The x-ray tube is
enclosed in a casing to prevent electrical shock. The x-ray tube's housing is not involved in the creation of images.
What is the name of the radiation-induced reddening of irritated skin?
Explanation:
Erythema is skin redness brought on by clogged capillaries or increased blood flow in the skin's deeper
layers. Erythema is a frequent adverse reaction to radiation.
