In preparation for a patient having a Schilling test, the nurse should explain that the test:
will confirm a diagnosis of G6PD anemia.
requires the patient to be NPO for 12 hours prior to the test.
is a 24-hour urine specimen collection test.
entails administration of methylcellulose prior to the test.
The Correct Answer is C
Choice A reason: The Schilling test is not used to diagnose G6PD anemia, which is a genetic disorder that causes red blood cells to break down when exposed to certain substances. The Schilling test is used to measure how well the body absorbs vitamin B12 from the intestine. ¹²
Choice B reason: The Schilling test does not require the patient to be NPO (nothing by mouth) for 12 hours prior to the test. The patient can drink water, but should avoid food for 8 hours before the test. ²
Choice C reason: The Schilling test is a 24-hour urine specimen collection test. The patient is given a dose of radioactive vitamin B12 by mouth and another dose of nonradioactive vitamin B12 by injection. The urine is collected for 24 hours to measure how much of the radioactive vitamin B12 is excreted. This indicates how well the body absorbs vitamin B12 from the intestine. ¹²
Choice D reason: The Schilling test does not entail administration of methylcellulose prior to the test. Methylcellulose is a type of laxative that can interfere with the absorption of vitamin B12. The patient should avoid taking any laxatives, antacids, or antibiotics before the test. ²³

Correct Answer is A
Explanation
Choice A reason: This is the correct answer. Stool for occult blood is a diagnostic test that detects the presence of hidden blood in the feces. This can indicate bleeding in the gastrointestinal tract, which is the most common cause of chronic iron deficiency anemia. Iron deficiency anemia is a condition where the body does not have enough iron to produce hemoglobin, the protein that carries oxygen in the red blood cells.
Choice B reason: Vitamin B12 level is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Vitamin B12 level is a blood test that measures the amount of vitamin B12 in the body. Vitamin B12 is a nutrient that is essential for the production of red blood cells and the maintenance of the nervous system. Vitamin B12 deficiency can cause pernicious anemia, a type of megaloblastic anemia where the red blood cells are large and immature.
Choice C reason: Schilling's test is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Schilling's test is a urine test that evaluates the absorption of vitamin B12 in the body. It involves giving the client an oral dose of radioactive vitamin B12 and an intramuscular injection of non-radioactive vitamin B12. The urine is then collected and measured for the amount of radioactive vitamin B12. Schilling's test can help diagnose pernicious anemia and other causes of vitamin B12 malabsorption.
Choice D reason: Bone marrow aspiration study is not the diagnostic test that is used to detect the most common cause of chronic iron deficiency anemia. Bone marrow aspiration study is a procedure that involves taking a sample of bone marrow from the hip or sternum and examining it under a microscope. Bone marrow is the soft tissue inside the bones that produces blood cells. Bone marrow aspiration study can help diagnose various blood disorders, such as leukemia, lymphoma, and aplastic anemia.
Correct Answer is D
Explanation
Choice A reason: The 68-year-old male who smokes one pack of cigarettes per day is not likely to have folic acid deficiency. Smoking can increase the risk of many health problems, such as lung cancer, heart disease, and stroke, but it does not affect the absorption or metabolism of folic acid. ¹ Folic acid is a type of vitamin B that is essential for the production of red blood cells and DNA. ²
Choice B reason: The 47-year-old male construction foreman who takes atenolol is not likely to have folic acid deficiency. Atenolol is a drug that lowers blood pressure and heart rate by blocking the effects of adrenaline. ³ It does not interfere with the absorption or metabolism of folic acid.
Choice C reason: The 35-year-old female who drinks a glass of wine with dinner is not likely to have folic acid deficiency. Moderate alcohol consumption, defined as one drink per day for women and two drinks per day for men, does not affect the absorption or metabolism of folic acid. However, excessive alcohol intake can impair the absorption of folic acid from the intestine and increase its excretion from the urine, leading to folic acid deficiency.
Choice D reason: The 43-year-old female with Crohn's disease is the most likely to have folic acid deficiency. Crohn's disease is a chronic inflammatory condition that affects the digestive tract, causing symptoms such as diarrhea, abdominal pain, and weight loss. Crohn's disease can impair the absorption of folic acid from the intestine, especially if the disease affects the small intestine, where most of the folic acid is absorbed. Crohn's disease can also increase the demand for folic acid, as inflammation and tissue damage require more folic acid for repair and regeneration.
