A nurse is teaching a client about foods high in iron. Which of the following food choices by the client indicates an understanding of the teaching?

Choice A reason: Reducing the client's sodium intake is an appropriate intervention for the nurse to take because it can help prevent fluid retention and edema, which are complications of heart failure. Sodium intake should be limited to 2 g per day or less for clients who have heart failure.

Choice B reason: Restricting the client's protein intake is not an appropriate intervention for the nurse to take because it can cause malnutrition and muscle wasting, which can worsen heart failure. Protein intake should be adequate to meet the client's nutritional needs and support cardiac function. Protein intake should be about 0.8 to 1.2 g per kg of body weight per day for clients who have heart failure.

Choice C reason: Weighing the client once per week is not an appropriate intervention for the nurse to take because it can delay the detection and treatment of fluid overload, which can worsen heart failure. The client should be weighed daily at the same time and with the same scale and clothing to monitor fluid status and adjust medication dosage.

Choice D reason: Providing the client with three large meals per day is not an appropriate intervention for the nurse to take because it can increase the workload of the heart and cause dyspnea, fatigue, or chest pain, which are symptoms of heart failure. The client should be provided with small, frequent meals that are low in sodium, fat, and cholesterol to reduce cardiac stress and promote digestion.

Choice A reason: Checking blood glucose level is an appropriate action for the nurse to take because it can help determine if the client has hypoglycemia or hyperglycemia, which are both complications of diabetes mellitus that can cause dizziness and weakness. Blood glucose level should be checked using a glucometer and compared with the normal range of 70 to 130 mg/dL before meals and less than 180 mg/dL after meals.

Choice B reason: Giving insulin injection is not an appropriate action for the nurse to take without checking blood glucose level first because it may cause hypoglycemia, which is a condition in which blood glucose level drops below 70 mg/dL and can cause dizziness, weakness, confusion, sweating, and seizures. Insulin injection should be given according to the prescribed dose, type, and schedule.

Choice C reason: Offering orange juice is not an appropriate action for the nurse to take without checking blood glucose level first because it may cause hyperglycemia, which is a condition in which blood glucose level rises above 180 mg/dL and can cause dizziness, weakness, thirst, polyuria, and ketoacidosis. Orange juice should be offered only if the client has hypoglycemia and is conscious and able to swallow.

Choice D reason: Applying cold compress is not an appropriate action for the nurse to take because it does not address the underlying cause of dizziness and weakness in a client who has diabetes mellitus. Cold compress may worsen the symptoms by reducing blood flow and oxygen delivery to the brain. Cold compress should be applied only if the client has fever, inflammation, or pain.
