A nurse is caring for a client who is experiencing an exacerbation of heart failure.

Findings upon admission:

The nurse is assessing the client 24 hr later. How should the nurse interpret the findings related to the diagnosis of heart failure?

Sickle Cell Disease:
• Fatigue

Iron Deficiency Anemia:
• Ferritin level
• Fatigue
• Orthostatic hypotension

Pernicious Anemia:
• Vitamin B12 level
• Fatigue

Rationale:

• Vitamin B12 level: A decreased vitamin B12 level is characteristic of pernicious anemia, which results from impaired absorption of vitamin B12 due to intrinsic factor deficiency.

• Orthostatic hypotension: A drop in blood pressure upon standing is commonly seen in iron deficiency anemia due to reduced oxygen-carrying capacity and inadequate perfusion.

• Ferritin level: A low ferritin level indicates depleted iron stores, which is a hallmark of iron deficiency anemia.

• Fatigue: Fatigue is a common symptom in all three conditions due to reduced oxygen delivery to tissues. In sickle cell disease, fatigue results from chronic hemolysis and vaso-occlusive episodes. In iron deficiency anemia, it is caused by insufficient hemoglobin production. In pernicious anemia, fatigue results from ineffective erythropoiesis due to vitamin B12 deficiency.

• "The iron supplement might cause my stools to be black.": This statement is correct as one of the common side effects of iron supplementation is darkening of the stools. This occurs due to the unabsorbed iron and is generally harmless, but clients should be educated about this to avoid confusion with gastrointestinal bleeding.
• "I should increase green leafy vegetables in my diet.": Green leafy vegetables are excellent sources of iron, particularly non-heme iron, which can help improve the client's iron levels. Encouraging a diet rich in iron-rich foods is essential for effective management of iron deficiency anemia, especially for clients on a vegan diet.
• "I will take my iron supplement 1 hour before a meal.": Taking iron supplements on an empty stomach enhances absorption. Clients should be instructed to take the supplement ideally 1 hour before meals or 2 hours after meals for optimal efficacy, unless gastrointestinal discomfort occurs.

• "I should expect to have swelling in my feet.": This statement is not appropriate. Swelling in the feet may indicate fluid retention or other medical issues that should be reported. It is not a typical or expected side effect of iron supplementation or iron deficiency anemia.
• "The iron supplement might cause ringing in my ears.": Ringing in the ears (tinnitus) is not a common side effect of iron supplements. If a client experiences this symptom, it may be related to other factors or medications and should be investigated further.
