A carcinoembryonic antigen (CEA) test was ordered and the patient is asking what this value will indicate. Which of the following is correct?
CEA is a chemotherapy drug used to treat cancer.

CEA is a tumor suppressor gene that inhibits the growth of cancer cells.
CEA is a blood test used to detect and monitor certain types of cancer.
The Correct Answer is D
Choice A rationale

Choice B rationale
CEA is not a surgical procedure. It’s a type of protein in the body that can be measured through a blood test.

Correct Answer is B
Explanation
Choice A rationale
While administering pain medication may provide temporary relief, it does not address the underlying issue of a perforated ulcer, which is a medical emergency.
Choice B rationale
Preparing the client for surgery is the priority action for a nurse when a perforated ulcer is suspected. A perforated ulcer is a medical emergency that often requires immediate surgery.
Choice C rationale
Initiating IV fluid resuscitation may be part of the management for a suspected perforated ulcer, but it is not the first priority. The first priority is to stabilize the patient and prepare for possible surgery.
Choice D rationale

Correct Answer is D
Explanation
Choice A rationale
It is normal to have a sore throat following an EGD procedure. The endoscope is passed down the throat, which can cause temporary discomfort.
Choice B rationale
Patients do need someone to drive them home after an EGD. The sedatives used during the procedure can impair their ability to drive safely.
Choice C rationale
Patients will be left side-lying with the head of the bed elevated during the procedure. This position helps to prevent aspiration.
Choice D rationale
Patients cannot drink immediately after the procedure. They must wait until their gag reflex has returned, which can take a few hours.
