The nurse is caring for a client admitted with unstable angina. The laboratory result for the initial troponin I is elevated in this client. The nurse should recognize what implication of this assessment finding?

A. Take the medication with milk to increase absorption:

This statement is incorrect. Taking ferrous sulfate with milk or dairy products is not recommended as they can decrease iron absorption. It's advisable to take iron supplements with water or juice, preferably on an empty stomach or with a small amount of food.

B. Take the medication on an empty stomach:

This statement is partially correct. While taking ferrous sulfate on an empty stomach can enhance absorption, some individuals may experience gastrointestinal discomfort or irritation. Therefore, it's often recommended to take iron supplements with a small amount of food to minimize potential side effects.

C. Eat foods high in fiber while on this medication:

This statement is generally correct. Consuming foods high in fiber can help prevent constipation, which is a common side effect of iron supplements. Including fiber-rich foods in the diet, such as fruits, vegetables, whole grains, and legumes, can promote regular bowel movements.

D. Report stools that are dark in color immediately:

This statement is correct. Dark or black stools can indicate the presence of digested blood, which may occur due to iron supplementation. It's important to report such changes to the healthcare provider promptly for further evaluation.

E. Eating citrus fruit and juices are recommended with meals:

This statement is correct. Citrus fruits and juices, such as oranges, grapefruits, and lemon juice, contain vitamin C, which can enhance iron absorption. Consuming vitamin C-rich foods or drinks along with iron supplements can help improve iron uptake by the body.

A. "I have a difficult time falling asleep at night":

Difficulty falling asleep at night is not typically a direct symptom of iron-deficiency anemia. While anemia can lead to fatigue and general tiredness, which might affect sleep quality, insomnia or difficulty falling asleep may have various causes unrelated to anemia. These causes can include stress, anxiety, poor sleep hygiene, or other underlying medical conditions.

B. "I have an increase in my appetite":

This choice is not directly related to iron-deficiency anemia. While some individuals with anemia may experience changes in appetite, such as increased hunger, this symptom is not specific to iron-deficiency anemia alone. An increase in appetite can have various causes, including hormonal changes, dietary changes, medications, or psychological factors.

C. "I have difficulty breathing when walking 30 feet":

This choice is the correct answer. Difficulty breathing, especially during exertion like walking, is a hallmark symptom of iron-deficiency anemia. Anemia reduces the oxygen-carrying capacity of the blood, leading to inadequate oxygen delivery to tissues, which can result in shortness of breath, fatigue, and difficulty with physical activities.

D. "I feel hot all of the time":

Feeling hot all the time is not a specific symptom of iron-deficiency anemia. While anemia can cause symptoms such as fatigue, weakness, pale skin, and shortness of breath, it does not directly lead to a constant feeling of heat or warmth throughout the body. Feeling hot or experiencing excessive sweating could be due to other factors such as hormonal changes, fever, hyperthyroidism, or environmental conditions.
