Question

The client is admitted with SIADH. The nurse should prepare to administer a solution containing which of the following? A. Magnesium B. Phosphorus C. Calcium D. Sodium

Short answer

Answer: Sodium

Step-by-step solution

Understand SIADH

SIADH is a condition where the body produces too much antidiuretic hormone (ADH), leading to water retention and electrolyte imbalances. The hallmark of SIADH is hyponatremia, which is a low blood sodium concentration. Patients with SIADH may experience symptoms such as lethargy, headache, nausea, and seizure. The primary goal in treating SIADH is to correct this electrolyte imbalance.

Analyze the options

In this case, we are given four options for a solution to be administered to the patient: Magnesium, Phosphorus, Calcium, and Sodium. Let's consider each option individually. A. Magnesium: This electrolyte plays a role in many essential body functions, but it is not directly related to sodium levels or fluid balance. B. Phosphorus: This is another important electrolyte, but again, it does not directly relate to sodium levels or fluid balance. C. Calcium: While calcium is crucial for bone health and muscle function, it is not the primary electrolyte involved in fluid balance and the correction of hyponatremia. D. Sodium: Sodium is the key electrolyte responsible for regulating fluid balance in the body. A patient with SIADH would be hyponatremic, meaning they have low blood sodium levels.

Choose the correct solution

Based on our analysis of each option and their relevance to SIADH, we can determine that the nurse should prepare a solution containing Sodium (option D) for the client. Sodium will directly address the low blood sodium levels associated with SIADH and work towards correcting the fluid imbalance.
