Correct Answer is C
Explanation
A. Decreasing intake of foods high in fiber is not necessary; in fact, fiber can help prevent constipation, a common side effect of iron supplements.
B. Vitamin C actually enhances the absorption of iron; thus, avoiding it is incorrect. Clients should be encouraged to consume vitamin C alongside their iron supplements to improve absorption.
C. Stools becoming darker in color is a common and expected side effect of ferrous sulfate due to the presence of unabsorbed iron. It is important for clients to know this to avoid unnecessary alarm.
D. Taking the medication on a full stomach may decrease absorption; it is generally recommended to take iron supplements on an empty stomach for optimal absorption unless gastrointestinal upset occurs.
Correct Answer is B
Explanation
A. While deep breathing can help alleviate pain, it is not the primary cause of pain in sickle cell anemia; this response could minimize the client's experience.
B. Sickle cell anemia causes red blood cells to become rigid and shaped like a sickle, which can obstruct blood flow and lead to vaso-occlusive crises, resulting in pain.
C. Although sickle cell anemia is a genetic disorder, simply stating that the mutated gene causes increased pain is too vague and does not explain the pain mechanism adequately.
D. While anemia can contribute to fatigue and some discomfort, the pain in sickle cell anemia is primarily due to the sickling of red blood cells and subsequent blockage of blood flow, rather than just the lack of hemoglobin.
