Oral and rectal administration contrast studies are diagnostic imaging techniques used to visualize the gastrointestinal tract. In oral administration, a contrast agent is ingested to highlight the esophagus, stomach, and intestines on imaging scans, while rectal administration involves introducing the contrast agent through the anus to visualize the lower gastrointestinal tract. Each method has its advantages depending on the area of interest and the specific clinical scenario, with oral contrasts being useful for upper GI evaluations and rectal contrasts for lower GI assessments. The choice between the two often depends on patient comfort, the specific diagnosis needed, and the type of imaging being performed.

How do rectal and axillary temperatures compare with oral temperatures?
rectal is higher ;axillary is lower
How is the contrast agent for a computed tomography scan given?
The patient may drink this contrast, or receive it in an enema. Oral and rectal contrast are usually given when examining the abdomen or cells, and not given when scanning the brain or chest. Iodine is the most widely used intravenous contrast agent
Why is rectal temp higher than oral temp?
Rectal temperature is much less influenced by other factors.
What is the temperature difference at rectal oral and under the arms?
Rectal is usually .5c above oral, with under arms being .5c below oral Remember 37C is just an average for oral temp and can change through out the day as well
Oral drug administration?
Oral drug administration is taking medicine via the mouth.
Why is it important to take body temperature oral and rectal thermometer?
for safety
Is oral route of administration safer?
Yes the oral route for drug administration is the safest route.
Why omnipaque is not used as oral contrast agent in Ct scan and urografin is used as oral contrast agent?
It shoould be the other way round. Urografin is not licensed for oral use and should not be used as an oral contrast agent. Omnipaque is licenced for oral used and should be used as an oral contrast agent. Check the manufacturer's product data sheets to confirm.
What is the difference between a rectal thermometer and an oral thermometer?
The tastes differ. An oral thermometer has a longer slender end that's inserted (into the mouth), compared to a rectal thermometer that has a short bulbous end inserted (into the rectum). The bulb reduces the chance of tearing the rectal wall, especially in infants. Some digital models have a setting for rectal vs. oral on the unit. The rectal temperature is known to be a little warmer and more accurate to body temperature. If you still have a glass and Mercury thermometer, be aware that mercury is a deadly toxin, and consider replacing the thermometer with a digital model.
Why is there such a difference between oral and rectal temperature in my son...orally he is almost always normal or low grade then rectal it is 101-102 degrees?
Rectal is more accurate because it takes the core body temperature.
What auxiliary label is used with oral suspensions?
for rectal use only
Is a rectal thermometer reading of 101 degrees equal to an oral thermometer reading of 101degrees?
No, a rectal thermometer reading is typically about 0.5 to 1 degree Fahrenheit higher than an oral thermometer reading. So a rectal thermometer reading of 101 degrees would roughly correspond to an oral thermometer reading of 100-100.5 degrees. It's important to use the same type of thermometer for consistent readings.
