The nurse is caring for a patient admitted to the hospital with chronic anemia. The patient reports persistent fatigue, weakness, and activity intolerance. Which intervention will the nurse implement for these manifestations?

Choice A reason: Potassium supplements can actually be important for patients on diuretic therapy, especially if they are taking loop diuretics like furosemide, which can cause potassium loss. However, it is important to monitor potassium levels and follow the physician's guidance on supplement use.

Choice B reason: Instructing the patient to take diuretics at bedtime is not recommended. Diuretics should be taken in the morning to avoid frequent urination during the night, which can disrupt sleep.

Choice C reason: Notifying the physician if weight increases by three pounds in one week is a key instruction for patients with heart failure. Rapid weight gain can indicate fluid retention and worsening heart failure, requiring prompt medical evaluation and adjustment of treatment.

Choice D reason: Administering diuretics in the morning and notifying the physician of decreased urine output is important, but the focus on notifying the physician about significant weight gain provides a more specific and actionable guideline for managing heart failure.

Choice A reason: Encouraging the patient to rest in bed for most of the day may lead to further deconditioning and muscle weakness. While rest is important, balancing activity and rest is more beneficial for managing fatigue in chronic anemia.

Choice B reason: Administering a high-protein diet including caffeinated beverages to increase energy levels is not recommended. While a high-protein diet can support energy and muscle strength, caffeine may cause jitteriness and disrupt sleep, which can exacerbate fatigue.

Choice C reason: Assisting the patient with ADLs and encouraging frequent rest periods is appropriate for managing fatigue, weakness, and activity intolerance in chronic anemia. This approach helps the patient conserve energy while maintaining some level of activity to prevent deconditioning.

Choice D reason: Providing supplemental oxygen via face mask during vigorous exercises is not appropriate. Patients with chronic anemia should avoid vigorous exercises that could exacerbate fatigue and weakness. The focus should be on moderate, manageable activities with adequate rest.
