A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make?

A. NPH insulin: NPH insulin, also known as Neutral Protamine Hagedorn, is an intermediate acting insulin. It has a slower onset of action and a longer duration compared to regular insulin. It is not the best choice for treating diabetic ketoacidosis (DKA) because it does not act quickly enough to lower dangerously high blood glucose levels in this acute situation.

B. Insulin glargine: Insulin glargine is a long-acting basal insulin. It has a slow, steady release and provides a consistent level of insulin over an extended period. Like NPH insulin, it is not suitable for rapidly lowering blood glucose levels in a DKA emergency.

C. Insulin detemir: Insulin detemir is another long-acting basal insulin similar to glargine. It has a slow onset and provides a sustained release of insulin. It is not the first-line choice for treating DKA due to its slower action.

D. Regular Insulin: Regular insulin, also known as short-acting or fast-acting insulin, has a rapid onset of action. When administered intravenously, it can quickly lower blood glucose levels. This makes it the preferred choice for treating diabetic ketoacidosis (DKA) where prompt action is essential to correct the severe hyperglycemia and associated metabolic imbalances.

A. Flaccid muscles are associated with conditions like hypokalemia, not hypoparathyroidism. In hypoparathyroidism, there is a deficiency of parathyroid hormone (PTH), which leads to low calcium levels and can result in muscle spasms and tetany, not flaccid muscles.

B. While anorexia can occur in clients with various health conditions, it is not a specific finding associated with hypoparathyroidism.

C. Correct. Hypoparathyroidism is characterized by low levels of parathyroid hormone (PTH), which leads to low calcium levels in the blood. This can cause symptoms such as numbness, tingling, and muscle cramps, especially in the extremities.

D. A positive Chvostek's sign is associated with hypocalcemia, which can be caused by hypoparathyroidism. Therefore, a negative Chvostek's sign would not be an expected finding in a client with hypoparathyroidism.
