Rationale: Because the abuse of alcohol is a common factor associated with the development of pancreatitis, the first assessment step is to screen for alcohol use using a validated screening questionnaire. The SMAST-G is a short-form alcoholism screening instrument tailored specifically to the needs of the older adult. If the patient scores positively on the SMAST-G, then the CIWA-Ar would be a useful tool for determining treatment. The DAST-10 provides more general information regarding substance use. The Mini-Mental State Examination is used to screen for cognitive impairment.

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Oral hypoglycemic agents are not appropriate in the acute setting of DKA as they may not work quickly enough. Sodium bicarbonate may be used in some cases to correct acidosis, but insulin administration takes precedence. Providing a high-calorie diet is not appropriate initially in DKA management, as the focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.

Correct Answer: A
