Extract:
Question 1 of 5
Clients taking metformin (Glucophage) should be monitored for this rare but potentially fatal adverse effect:
Correct Answer: D
Rationale: Lactic acidosis is a rare but serious metformin complication, especially with renal impairment, due to drug accumulation. Respiratory acidosis, hyperlipidemia, and hypertension are not typical metformin side effects.
Question 2 of 5
By which routes can insulin be administered? (Select All that Apply.)
Correct Answer: A,D
Rationale: Insulin is commonly administered subcutaneously for routine management and intravenously in emergencies like diabetic ketoacidosis. Intradermal, oral, and topical routes are ineffective due to poor absorption or degradation.

Question 4 of 5
Which of the following orders would the LPN question in a patient with Type I diabetes?
Correct Answer: B
Rationale: Acarbose is an alpha-glucosidase inhibitor used for Type 2 diabetes to slow carbohydrate absorption, not typically for Type 1 diabetes where insulin is the primary treatment due to the absence of insulin production. Insulin glargine, lispro, and regular are all appropriate for Type 1 diabetes management, providing basal or bolus insulin coverage.
Question 5 of 5
Which hormone released by the Islets of Langerhans, acts to increase blood glucose?
Correct Answer: A
Rationale: Glucagon, secreted by pancreatic alpha cells in the Islets of Langerhans, raises blood glucose by promoting glycogenolysis and gluconeogenesis. Insulin, also from the Islets, lowers glucose, making glucagon the correct answer.
