A 26-year-old woman is being evaluated for vomiting and abdominal pain. Which question from the nurse will be most useful in determining the cause of the patient's symptoms?

The patient received 38 U of NPH insulin at 7:00 AM, and by 1:00 PM, the insulin has been active for approximately 6 hours. The patient has missed lunch, which may lead to hypoglycemia, especially with the activity of the insulin.

Sending a glass of orange juice will provide the patient with a quick source of glucose to prevent hypoglycemia. If testing is further delayed, the nurse may request that the patient be allowed to eat lunch first or save the lunch tray for later, but immediate intervention is necessary to prevent hypoglycemia. Discontinuing the evening dose of insulin is not an appropriate action and should not be considered without consulting the healthcare provider.

Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones. The initial management of DKA involves fluid resuscitation with intravenous normal saline to correct dehydration and electrolyte imbalances. Therefore, starting an infusion of normal saline at 125 ml/hr is the first prescribed action the nurse should implement.

Bringing the patient a meal is not a priority at this time because the patient's blood glucose levels need to be stabilized before they can safely consume food. Administering Lantus insulin IV and giving sodium bicarbonate 50 mEq IV push are also not the first-line treatments for DKA. Lantus insulin is a long-acting insulin used to treat hyperglycemia over an extended period and should not be given intravenously. Sodium bicarbonate may be used to correct acidosis, but it is not the first priority in DKA management.
