The nurse is caring for a patient who was admitted to the medical unit with a diagnosis of heart failure and has a history of hyperparathyroidism. The nurse reviews the following lab results in the chart below. Which order by the healthcare provider (HCP) will the nurse clarify/question?

• Brain (B-Type) Natriuretic Peptide: 210 pg/mL
• Potassium: 4.7 mg/dL
• Calcium: 14.1 mg/dL
• Sodium: 139 mEq/L
• BUN: 25 mg/dL
• Creatinine: 1.1 mg/dL

Choice A reason: Administering phosphate binders with meals is an essential intervention for managing renal osteodystrophy in patients with chronic kidney disease (CKD). Renal osteodystrophy results from an imbalance of calcium and phosphate in the body due to impaired kidney function. Phosphate binders help reduce the absorption of phosphate from the diet, thereby lowering serum phosphate levels and preventing complications such as secondary hyperparathyroidism and bone disorders. This intervention helps maintain the proper balance of minerals, improving bone health and reducing the risk of fractures and other skeletal complications in CKD patients.

Choice B reason: Encouraging the patient to increase potassium-rich foods is not appropriate for managing renal osteodystrophy. Patients with CKD often need to limit their potassium intake because impaired kidney function can lead to hyperkalaemia (elevated potassium levels), which is potentially life-threatening. Instead of promoting potassium-rich foods, the focus should be on controlling phosphate and maintaining calcium levels.

Choice C reason: Monitoring calcium levels for signs of hypocalcaemia is important in CKD management, but it is not the primary intervention for renal osteodystrophy. While hypocalcaemia can occur in CKD due to disrupted vitamin D metabolism, addressing phosphate levels through the use of phosphate binders is a more targeted approach to managing renal osteodystrophy and preventing secondary hyperparathyroidism.

Choice D reason: Increasing fluid intake to 3 litters per day is generally not recommended for CKD patients, especially those with reduced urine output or fluid retention issues. Excessive fluid intake can lead to fluid overload, hypertension, and heart failure in CKD patients. The intervention should focus on phosphate control rather than fluid intake adjustments.

Choice A reason: Weighing the patient using a bed scale and restricting oral fluids are important interventions for managing fluid balance in heart failure, but they are not the immediate priority. Assessing the respiratory status takes precedence to ensure the patient is not in respiratory distress.

Choice B reason: Obtaining pulse oximetry levels and assessing the respiratory status are priority actions. Dyspnea on exertion and fatigue indicate potential respiratory compromise, and it is crucial to evaluate oxygenation and respiratory function immediately.

Choice C reason: Elevating the lower extremity on two pillows while the patient is in bed can help reduce edema but is not the immediate priority. Respiratory assessment and stabilization take precedence.

Choice D reason: Obtaining a Physical Therapy consultation to evaluate activity tolerance is beneficial for long-term management but is not an immediate priority in acute care. The focus should be on assessing and stabilizing the patient's respiratory and cardiac status.
