Body substance precautions
the normal adult body temperature taken orally is:
98-99 deg F
Assessment (signs) of changing patient conditions includes observing for:
- Skin that becomes cool and diaphoretic
- Patient expressions of discomfort or dizziness

which may be ingested by a patient who has been placed on a clear liquid diet?
-Gelatin and Tea
Barium sulfate is classified as a(n):
Inert inorganic salt
A sphygmonmanometer is used to:
Measure blood pressure
A blood pressure of 120/80 mm Hg reveals that:
The pressure is 80 mm Hg when the heart is at rest
when oxygen is administered (transferred to patient), the usual rate is:
3 to 5 L/minute
A mechanical method used to clear the patient’s airway is called:
Suctioning (hut)
Which contains all the instruments and medications necessary (need) for dealing with cardiac arrest?
Crash cart
what condition is caused by loss of a large amount of blood or plasma?
Hypovolemic shock
what causes blood to pool in peripheral vessels?
Neurogenic shock
What follows an allergic reaction to foreign proteins?
Anaphylaxis
What is caused by infection that results in extremely low blood pressure?
Septic shock
What conditon occurs secondary to heart failure or interferrence with heart function?
Cardiogenic shock
what condition may occur after injection of an iodinated contrast agent?
Anaphylaxis
which is a symptom of shock?
- Accelerated pulse
- Cool, Clammy, pale skin
- Systolic pressure less than 30 mm Hg
what should the radiographer do first when it is suspected a patient is going into shock?
Place patient in Trendelenburg position
which statements apply when radiography is performed on trauma patients?
- Work quickly and efficiently
- Observe for changes in wound dressing while performing radiography
- Document in writing changes in patient condition
which is used to feed a patient or conduct gastric suction?
NG tube
which is used to administer (inject) nutrition or long-term chemotherapy?
Venous catheter
what is the site of most nosocomial infections?
Urinary catheter
what is another name for a mechanical respirator?
Ventilator
The most frequently (many) performed exam using a contrast medium is a(n)
Chest x-ray study
which statements are true concerning positive contrast media?
- Aqueous iodine compounds may be used if perforations are supsected (found)
- Barium is an inert substance
- Aqueous iodine compounds may cause serious dehydration
- Barium is a surgical contaminant
which is a legitimate (good) contraindication to the use of iodinated contrast media?
Allergy to any medications
A reaction at the site of injection of iodinated contrast media may be caused by
Extravasation of contrast agent
which is a symptom (are symptoms) of a contrast agent reaction?
1-Hoarseness (giọng khàn khàn)
2-Sneezing
3-Urticaria (rash,mày đay)
after injection of iodinated contrast media, the tech should:
Remain with the patient and have a conversation with the patient, listening for signs of laryngeal swelling
at the first indication of a contrast agent reaction, the tech should:
Stop the exam and obtain help so as not to alarm the patient
Hypodermic needles are described by their gauge which is a:
Measure of the diameter of the needle opening, the larger the gauge, the smaller the diameter
Air must NOT be injected when performing venipuncture [lay mau] becasue:
An air embolus [vật tắc mạch] would form that may be fatal to the patient
A smaller, easier-to-handle injection set that includes plastic projections on both sides of the needle and may be used for venipuncture is called a:
Butterfly
A venous catheter:
- Is more flexible and easier to use than a needle or butterfly
- Is a combination unit with a needle inside a flexible plastic catheter; both the needle and the catheter are inserted into the vein, after that the needle is withdraw
Place the steps for performing venipuncture in the proper order:
1-Wash hands 2-Put on gloves 3-Secure tourniquet in place 4-Select vein 5-Thoroughly cleanse [lay thiet ky] the skin 6-Perform puncture 7-Observe blood return 8-Inject contrast agent 9-Cover wound and compress site 10-Check wound for swelling
Venipuncture (lay mau):
May be performed by a tech only where allowed by state law
A contrast medium overdose;
May occur in infants or adults with renal, cardiac, or hepatic failure
If medication needs to be ordered for a patient in the radiology department, a physician always:
- Chooses the drug and the dosage
- Selects the route of administration
A patient who has sustained (bi.) a head injury in a motor vehicle accident arrived in the rad department alert and well oriented. When radiographing the patient, the tech observed that hte patient was becoming drowsy (me mang), irritable, and less coherent. What would be the correct action for the tech to take?
