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
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: Respiratory alkalosis is not the correct answer. Respiratory alkalosis is a condition where the blood pH is high (above 7.45) due to low carbon dioxide levels (below 35 mmHg) caused by hyperventilation. The client's blood pH is low (7.2) and the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory alkalosis.
Choice B reason: Metabolic alkalosis is not the correct answer. Metabolic alkalosis is a condition where the blood pH is high (above 7.45) due to high bicarbonate levels (above 26 mEq/L) caused by excessive loss of acids or intake of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which does not indicate metabolic alkalosis.
Choice C reason: Respiratory acidosis is not the correct answer. Respiratory acidosis is a condition where the blood pH is low (below 7.35) due to high carbon dioxide levels (above 45 mmHg) caused by hypoventilation. The client's blood pH is low (7.2) but the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory acidosis.
Choice D reason: This is the correct answer. Metabolic acidosis is a condition where the blood pH is low (below 7.35) due to low bicarbonate levels (below 22 mEq/L) caused by excessive production or intake of acids or loss of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which indicates metabolic acidosis.
Correct Answer is A
Explanation
Choice A reason: Performing daily weights is the best method to evaluate the client's response to furosemide, a drug that reduces fluid retention and swelling by increasing the urine output. ¹ Daily weights can help monitor the changes in the client's fluid status and the effectiveness of the drug. The nurse should weigh the client at the same time each day, using the same scale and clothing.
Choice B reason: Taking the blood pressure is not the best method to evaluate the client's response to furosemide. Furosemide can also lower the blood pressure by reducing the volume of fluid in the blood vessels. ¹ However, blood pressure can be influenced by many other factors, such as heart rate, stress, or medications. Blood pressure is not a reliable indicator of the client's fluid status or the effectiveness of the drug.
Choice C reason: Auscultating breath sounds is not the best method to evaluate the client's response to furosemide. Furosemide can help improve the breath sounds by reducing the fluid accumulation in the lungs, which can cause shortness of breath or crackles. ¹ However, breath sounds can also be affected by other factors, such as lung infections, asthma, or allergies. Breath sounds are not a reliable indicator of the client's fluid status or the effectiveness of the drug.
Choice D reason: Measuring urinary output is not the best method to evaluate the client's response to furosemide. Furosemide can increase the urinary output by stimulating the kidneys to excrete more water and electrolytes. ¹ However, urinary output can also vary depending on the fluid intake, kidney function, or other medications. Urinary output is not a reliable indicator of the client's fluid status or the effectiveness of the drug.
