The nurse is explaining to a patient the purpose of certain lab tests that have been ordered.
A carcinoembryonic antigen (CEA) test was ordered and the patient is asking what this value will indicate. Which of the following is correct?

Choice A rationale
Acquired hemolytic anemia is a condition where the body destroys red blood cells faster than it can produce them, but it is not typically associated with the need for lifelong vitamin B12 supplementation following stomach surgery.
Choice B rationale
Pernicious anemia is a condition that can develop in patients who have had a large portion of their stomach surgically removed. This is because the stomach plays a crucial role in the absorption of vitamin B12. Without sufficient stomach tissue, the body may not be able to

absorb enough vitamin B12 from food, leading to a deficiency. Therefore, these patients often require lifelong vitamin B12 supplementation.
Choice C rationale
Iron-deficiency anemia is typically caused by a lack of iron in the diet, not a lack of vitamin B12. Therefore, patients with this condition would not typically require lifelong vitamin B12 supplementation following stomach surgery.
Choice D rationale
Sickle cell anemia is a genetic disorder that affects the shape and function of red blood cells. It is not typically associated with the need for lifelong vitamin B12 supplementation following stomach surgery.

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
Obtaining a stat abdominal X-ray may help confirm the diagnosis of a perforated ulcer, but it is not the first priority. The first priority is to stabilize the patient and prepare for possible surgery.
