A nurse is teaching a client who has iron deficiency anemia about ferrous sulfate. Which of the following instructions should the nurse include in the teaching?
A.
Take the ferrous sulfate with an antacid.
B.
Take the ferrous sulfate with yogurt.
C.
Take the ferrous sulfate at bedtime.
D.
Take the ferrous sulfate between meals.
The correct answer and Explanation is :
The correct answer is D. Take the ferrous sulfate between meals.
Explanation:
Ferrous sulfate is a commonly prescribed oral iron supplement used to treat iron deficiency anemia. To maximize its absorption and effectiveness, specific guidelines on its administration are recommended:
- Optimal Absorption: Iron is best absorbed in an acidic environment, and the absorption rate can be significantly improved if the supplement is taken between meals. Meals can increase the pH in the stomach and intestines, which may inhibit iron absorption. Therefore, taking ferrous sulfate on an empty stomach or between meals, where the environment is more acidic, enhances its absorption.
- Avoiding Antacids: Antacids can neutralize stomach acid, which can decrease the absorption of iron. For this reason, it’s advised to avoid taking ferrous sulfate with antacids. If an antacid is necessary, it should be taken at least 2 hours before or after the iron supplement.
- Yogurt and Dairy Products: Dairy products like yogurt contain calcium, which can also interfere with the absorption of iron. Therefore, ferrous sulfate should not be taken with dairy products. Calcium competes with iron for absorption in the intestines, potentially reducing the effectiveness of the iron supplement.
- Timing of Administration: Taking ferrous sulfate at bedtime is not recommended because iron can cause gastrointestinal discomfort, such as nausea or upset stomach, which might disturb sleep. Additionally, the absorption of iron might be compromised if the stomach is not in an optimal state for processing the supplement.
In summary, taking ferrous sulfate between meals helps to maximize its absorption by avoiding interactions with dietary components that may inhibit iron uptake. Following this guideline can contribute significantly to the effectiveness of the treatment for iron deficiency anemia.
