A necessary intervention for patients with pancreatitis is blood sugar monitoring.

Choice A reason: Fluid volume overload is not typically associated with diabetes insipidus. Instead, patients with diabetes insipidus often experience fluid volume deficit due to excessive urine output.

Choice B reason: Hyperglycemia is not a characteristic problem of diabetes insipidus. This condition involves an imbalance in water regulation due to insufficient production or response to antidiuretic hormone (ADH), rather than issues related to blood glucose levels.

Choice C reason: Nocturia, or frequent urination at night, is a common problem in diabetes insipidus. Patients with this condition produce large amounts of dilute urine, which can lead to frequent nighttime urination.

Choice D reason: Generalized edema is not a typical problem in diabetes insipidus. Edema is more commonly associated with conditions involving fluid retention, such as heart failure or kidney disease, rather than the excessive fluid loss seen in diabetes insipidus.

Choice A reason: NPH (Humulin N) is an intermediate-acting insulin that is used to control blood sugar levels throughout the day, not specifically for mealtime coverage. It is typically administered twice a day.

Choice B reason: Detemir (Levemir) is a long-acting insulin that provides basal insulin coverage. It helps maintain blood sugar levels stable over a 24-hour period and is not intended for controlling post-meal blood sugar spikes.

Choice C reason: Lispro (Humalog) is a rapid-acting insulin used for mealtime coverage. It is designed to be taken just before or immediately after a meal to control the sudden rise in blood sugar levels that occurs after eating.

Choice D reason: Glargine (Lantus) is a long-acting insulin that provides basal insulin coverage, helping to maintain steady blood glucose levels throughout the day and night. It is not used for mealtime blood sugar control.
