The nurse is monitoring a client receiving bisphosphonate therapy for Paget's disease. Which laboratory parameter should the nurse prioritize monitoring during treatment?

Enlarged frontal bossing (prominent forehead) is a cranial finding often seen in clients with Paget's disease due to increased bone growth in the skull bones. This can cause pressure and contribute to headaches.

a. Nystagmus: Nystagmus is an involuntary, rhythmic movement of the eyes and is not directly associated with Paget's disease.

b. Diplopia: Diplopia, or double vision, is not a typical finding in Paget's disease. It may be related to other neurological or ocular conditions.

c. Papilledema: Papilledema is swelling of the optic disc due to increased intracranial pressure. While headaches can be associated with Paget's disease, papilledema is not a common manifestation of the condition.

Calcium and vitamin D help reduce the risk of bone fractures in Paget's disease.

Explanation: Adequate calcium and vitamin D intake are essential for maintaining bone health and reducing the risk of bone fractures, especially in individuals with Paget's disease. While these nutrients do not cure Paget's disease, they play a crucial role in supporting bone strength and density.

a. Calcium and vitamin D can prevent the development of Paget's disease: This statement is incorrect. Paget's disease is primarily a result of genetic factors, and calcium and vitamin D intake do not prevent its development.

c. Calcium and vitamin D can cure Paget's disease: This statement is incorrect. While calcium and vitamin D are important for bone health, they do not cure Paget's disease. Treatment usually involves medications to manage the condition.

d. Calcium and vitamin D decrease bone turnover in Paget's disease: This statement is not entirely accurate. Calcium and vitamin D do not directly decrease bone turnover in Paget's disease. Medications like bisphosphonates are prescribed to address bone remodeling.
