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?
CEA is a chemotherapy drug used to treat cancer.
CEA is a surgical procedure used to remove cancerous tumors.
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
CEA is not a chemotherapy drug. Chemotherapy drugs are medications used to treat cancer, while CEA is a protein that can be measured in the blood.
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.
Choice C rationale
CEA is not a tumor suppressor gene. Tumor suppressor genes are genes that regulate cell division and prevent the formation of tumors, while CEA is a protein that can be present in higher amounts in people with certain types of cancer.
Choice D rationale
CEA is a blood test used to detect and monitor certain types of cancer. It’s often used in people who’ve been previously diagnosed with certain types of cancer, most commonly colorectal cancer.

Correct Answer is B
Explanation
Choice A rationale
Drinking a glass of water with each meal is not typically recommended for patients with dumping syndrome. In fact, it’s often suggested to avoid drinking liquids until at least 30 minutes after a meal.
Choice B rationale
Increasing protein in the diet is indeed a good recommendation for a patient with dumping syndrome. High-protein foods can help to slow the rate of gastric emptying and reduce symptoms.
Choice C rationale
Eating three moderate-sized meals a day might not be the best advice for a patient with dumping syndrome. Instead, it’s often recommended to eat smaller, more frequent meals throughout the day.
Choice D rationale
Eating a bedtime snack that contains a milk product is not typically recommended for patients with dumping syndrome. Dairy products can sometimes exacerbate symptoms.
Correct Answer is ["2"]
Explanation
Step 1: Identify the dose of aspirin the nurse needs to administer, which is 650 mg. Step 2: Identify the available dose, which is 325 mg per tablet.
Step 3: Calculate the number of tablets needed by dividing the required dose by the dose available per tablet. So, 650 mg ÷ 325 mg/tablet.
Step 4: The calculation gives us 2. Therefore, the nurse should administer 2 tablets.
