The nurse recognizes that which diagnostic test is used to detect the most common cause of chronic iron deficiency anemia?

Stool for occult blood

Vitamin B12 level

Schilling's test

Bone marrow aspiration study

Answer and Explanation

The Correct Answer is A

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: Taking a baby aspirin with a full glass of cold water at bedtime is not a good discharge instruction for this client. Aspirin can increase the risk of bleeding, especially in the stomach and intestines. ¹ Taking aspirin at bedtime may increase the exposure of the GI mucosa to the drug and worsen the bleeding. ² Cold water may also irritate the stomach lining and cause discomfort.

Choice B reason: Taking 81 mg of enteric coated aspirin with orange juice at lunch time is not a good discharge instruction for this client. Enteric coated aspirin is designed to dissolve in the small intestine, not the stomach, to reduce the risk of GI bleeding. ³ However, orange juice is acidic and may damage the coating and release the aspirin in the stomach. ⁴ This may increase the bleeding and cause pain or ulcers.

Choice C reason: Taking the aspirin with some ginseng tea in the evening is not a good discharge instruction for this client. Ginseng is an herbal supplement that may interact with aspirin and increase the risk of bleeding. ⁵ Taking the aspirin in the evening may also have the same drawbacks as taking it at bedtime, as explained in choice A.

Choice D reason: Taking the aspirin with a glass of milk or food in the morning is the best discharge instruction for this client. Milk and food can help protect the stomach lining from the irritating effects of aspirin and reduce the risk of bleeding. Taking the aspirin in the morning can also minimize the exposure of the GI mucosa to the drug during the night, when the stomach is empty and more vulnerable. ²

A. Has gained 2 pounds and has pink buccal mucosa B. No longer has paresthesia of the hands and feet C. Realizes eating more iron fortified cereals D. Has stopped drinking any alcoholic beverages

Correct Answer is B

Explanation

Choice A reason: While gaining weight and having pink buccal mucosa can be signs of overall improved health, they are not specific indicators of effective treatment for vitamin B12 deficiency¹².

Choice B reason: Paresthesia (a sensation of tingling, tickling, pricking, or burning of a person's skin) of the hands and feet is a common symptom of vitamin B12 deficiency¹². If the client no longer has this symptom, it could indicate that the treatment for vitamin B12 deficiency has been effective¹².

Choice C reason: Eating more iron-fortified cereals can contribute to overall nutritional health, but it's not directly related to the treatment of vitamin B12 deficiency¹².

Choice D reason: While stopping alcohol consumption can improve overall health, it's not a specific indicator of effective treatment for vitamin B12 deficiency¹²..
