A client newly diagnosed with diabetes mellitus suddenly becomes confused and weak. Which intervention(s) should the nurse implement? Select all that apply.

Choice A reason: Checking the client's current fingerstick blood glucose is important to determine if the confusion and weakness are due to hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).Choice B reason: Obtaining blood pressure and heart rate is useful for a general assessment but is secondary to assessing blood glucose levels in this scenario.Choice C reason: Administering a PRN dose of regular insulin is not appropriate without first determining the client's blood glucose level. If the client is hypoglycemic, insulin could worsen the condition.Choice D reason: Giving the client 4 ounces (120 mL) of orange juice is a quick way to raise blood sugar levels if the client is hypoglycemic.Choice E reason: Providing diet carbonated soda is not effective for treating hypoglycemia because it does not contain sugar to raise blood glucose levels.
