Intrathecal injections of iodinated contrast media may be performed to evaluate the lumbar spine during a CT examination.

A suction unit used on  a patient with a chest tube should always remain 18 inches above the patient.

A normal range for the diastolic blood pressue of an adult is between 60-90mm Hg.

To calculate the flow rate for an intravenous contrast administration of 125mL contrast via an automatic injector in 50 seconds, divide the total seconds by the total volume of contrast.

The oral contrast media Gastrografin, barium sulfate and Hypaque pose no associated risk in a patient who is suspected of having a perforation of the digestive tract.

The signs and symptoms of hypovolemic shock include:
 
1. Hypertension
 
2. Pallor
 
3. Tachycardia
 
4. Oliguria

Iodinated contrast media is not commonly administered in the brachial artery.

Patient dose can be reduced by using a technique termed “partial scan” or “half-scan” which reduces the total rotation of the x-ray tube.

When using iodinated contrast media the viscosity can be decreased by an increase in temperature of the contrast media.

Dyspnea is an example of a mild reaction to iodinated intravenous contrast media.

The patient is not required to give informed consent for a noncontrast CT study of the brain to rule out a subdural hematoma.

Non-ionic contrast media include iopamidol, iohexol, and iodamide.

A patient arrives in the CT exam room from the ER, the technologist notices the IV bag is laying on the edge of the stretcher and blood has returned into the tubing, what if anything should be done?

When taking blood pressure the systolic pressure is represented by the top number and represents the measurement of the pressure exerted on the arterial walls during a contraction of the heart.

Which of the following describes the term urticaria?

The use of Epinephrine and Diphenhydramine should be used to combat bradycardia during a vagal reaction to contrast.

Initial treatment for a patient experiencing a severe vagal reaction to iodinated contrast media that includes bradycardia include:

The average osmolality of non-ionic intravenous contrast agents is 1300 mOsm/kg water.

A moderate adverse reaction to iodinated intravenous contrast media may include shock, syncope and severe vomiting.

The partial thromboplastin time is a laboratory measure of blood coagulation. The normal range should be between 17 – 21 seconds.

Intravenous drip infusion contrast material should be placed at a height of 18-24 inches above the patient to ensure correct flow and that no blood is returned into the tubing.

Gonadal shielding for a female patient may be used during CT examinations of the chest, abdomen, and brain.

A patient with an immunosuppressed condition is placed under contact precautions during their hospital stay to guard against the possible contamination of the patient with a potential infection.

The first step in cardiopulmonary resuscitation is involves a call for help from coworkers or emergency staff.
