Final answer:
The appropriate care for a 100-kg patient undergoing hemodialysis 3 days a week includes recommendations that should be tailored to individual requirements, considering calorie, protein, potassium, and fluid intake to prevent complications and support the patient's health in light of reduced kidney function. Option a is correct.
Step-by-step explanation:
The nurse's recommendation for a 100-kg patient receiving hemodialysis 3 days a week should consider several factors, including energy needs and the need to manage intake of certain nutrients to prevent overload given the compromised kidney function. Assuming normal activity levels and the patient's weight, a daily caloric intake of 2500 to 3500 kcal per day might be recommended, though individual needs can vary. For protein intake, the advice should typically be higher than less than 50 grams per day, as dialysis patients require more protein to compensate for losses during hemodialysis. Regarding potassium, a 10 mEq per day intake is likely too low given that the normal recommendation for adults is 4700 mg per day.
However, since kidneys in dialysis patients cannot excrete potassium effectively, the nurse might suggest a more restricted amount tailored to the patient's needs to prevent hyperkalemia. Lastly, a fluid intake of less than 500 mL per day is not recommended as it can lead to severe dehydration. Most dialysis patients are advised to limit their fluid intake, but the amount varies depending on urine output and fluid removal during dialysis, typically around 1-1.5 liters per day.
