The material in this exercise belongs to OET BANK — an online resource for Medical English learners preparing for OET.
The most important preparation requirements include obtaining a recent eGFR result,
and providing details of current prescriptions, over-the-counter medications and information on pregnancy status.
Please also ensure that patients follow a hydration fast for 4 hours prior to examination.
Patients with a recent history of fever, diarrhoea and dialysis are not suitable to undergo CT scans with contrast use.
The examination takes between 10 and 45 minutes depending on the procedure type,
and possible side effects include nausea, vomiting and dizziness.
The CT contrast usually stays in the patient's system for 48 hours after the injection,
and following the examination I recommend advising patients to drink plenty of extra water
as this encourages secretion of the CT contrast media.
Finally, if any complications such as allergic reactions, decreased urine output,
confusion, or blood in urine occur,
then please inform your patients to let medical staff know as soon as possible.
