A nurse is reinforcing teaching about pernicious anemia with a client following a total gastrectomy. Which of the following dietary supplements should the nurse include in the teaching as the treatment for pernicious anemia?
Folate
Vitamin C
Vitamin B12
Iron
The Correct Answer is C
A. Folate: Folate is important for red blood cell production but does not address the Vitamin B12 deficiency seen in pernicious anemia.
B. Vitamin C: Vitamin C does not impact pernicious anemia as it is not involved in Vitamin B12 absorption.
C. Vitamin B12: Pernicious anemia occurs due to a lack of intrinsic factor, which is necessary for Vitamin B12 absorption. After a total gastrectomy, intrinsic factor is no longer produced, requiring Vitamin B12 supplementation.
D. Iron: Iron deficiency anemia is different from pernicious anemia, which specifically requires Vitamin B12 supplementation.

Correct Answer is C
Explanation
A. Red blood cells (RBCs) 5.0 million/mm³ (F 4.2–5.4; M 4.7–6.1): This RBC count is within normal limits and does not indicate a concern related to thrombocytopenia.
B. Hemoglobin 14.5 g/100 mL (F 12–16; M 14–18): Hemoglobin is within normal limits and is not an immediate concern for a patient with ITP, as thrombocytopenia primarily affects platelets, not hemoglobin levels.
C. Platelets 50,000/mm³ (150,000–400,000): A platelet count of 50,000/mm³ is significantly below the normal range and poses a risk for bleeding, which is the primary concern in ITP (immune thrombocytopenic purpura).
D. White blood cells (WBCs) 7,400/mm³ (5,000–10,000): The WBC count is normal and not directly related to thrombocytopenia in ITP, which specifically affects platelets.
Correct Answer is A
Explanation
A. Activity intolerance related to tissue hypoxia: Pernicious anemia leads to a decrease in the body’s ability to carry oxygen due to a lack of intrinsic factor and subsequent vitamin B12 deficiency, resulting in tissue hypoxia. This can cause fatigue and activity intolerance as the body struggles to meet its oxygen demands.
B. Ineffective airway clearance related to dyspnea: Dyspnea may occur, but ineffective airway clearance is not directly related to pernicious anemia, as this condition primarily affects oxygen transport, not the airway.
C. Risk for infection related to reduction in white blood cells (WBCs): Pernicious anemia primarily affects red blood cells due to vitamin B12 deficiency; it does not typically lead to a reduction in white blood cells.
D. Chronic pain related to bone marrow dysfunction: While bone marrow may be affected in some anemias, chronic pain is not a typical symptom of pernicious anemia, and bone marrow dysfunction is not usually present.
