Which of the following orders would the LPN question in a patient with Type I diabetes?

Insulin glargine

Acarbose

Insulin lispro

Insulin regular

Answer and Explanation

The Correct Answer is B

A. Insulin glargine: Insulin glargine is a long-acting insulin used for basal insulin control in Type 1 diabetes, making it appropriate for this condition.
B. Acarbose: Acarbose is an alpha-glucosidase inhibitor used to treat Type 2 diabetes by slowing carbohydrate absorption in the intestines. It is not typically used in Type 1 diabetes, where insulin is the primary treatment. LPNs should question its use in Type 1 diabetic patients.
C. Insulin lispro: Insulin lispro is a rapid-acting insulin used to control blood sugar spikes after meals, making it suitable for Type 1 diabetes.
D. Insulin regular: Regular insulin is a short-acting insulin used to manage blood sugar levels, appropriate for Type 1 diabetes.

Correct Answer is D

Explanation

A. The patient may choke: This is not the primary concern for extended-release medications like metformin (Glucophage XL). While choking is a risk with any pill, it's not specific to the need for avoiding crushing or chewing extended-release formulations.
B. It would cause blood glucose levels to rise too rapidly: Crushing or chewing the medication would not cause blood glucose levels to rise rapidly. Instead, it could lead to a more rapid release and absorption of the drug, which might lower blood glucose too quickly, potentially leading to hypoglycemia.
C. Irritation of the oral mucosa may occur: While irritation of the oral mucosa could be a concern with some medications, it is not the primary reason for avoiding the crushing or chewing of extended-release formulations like Glucophage XL.
D. The effect of the medication may be changed: Crushing or chewing an extended-release tablet disrupts its formulation. Glucophage XL is designed to release metformin slowly over time. If the tablet is crushed or chewed, it can result in the entire dose being released at once, which can alter the intended pharmacokinetics and pharmacodynamics of the drug. This could lead to a higher risk of side effects and a loss of the extended-release benefit, ultimately changing the medication's effect and possibly leading to issues like hypoglycemia or gastrointestinal side effects.

Correct Answer is ["Glucagon"]

Explanation

The Islets of Langerhans in the pancreas produce two main hormones: insulin and glucagon. Insulin helps regulate blood sugar by lowering it, while glucagon acts conversely to raise blood sugar levels.
