Serge, who has diabetes mellitus, is taking oral agents and is scheduled for a diagnostic test that requires him to be NPO. What is the best plan of action for the nurse regarding Serge's oral medications?

Correct Answer: C

Rationale: The best plan of action for the nurse is to notify the physician and request orders regarding Serge's oral medications. By involving the physician, the nurse ensures that appropriate instructions are obtained, considering Serge's medical condition and the need for NPO status for the diagnostic test. Administering the medications without medical guidance (choice A) can be risky, as it may affect the test results. Notifying the diagnostic department (choice B) is not the most direct and appropriate action; the physician is the primary healthcare provider responsible for medication orders. Administering the medications with water before the test (choice D) is not advisable when the patient is supposed to be NPO, as it can interfere with the test requirements.

Correct Answer: B

Rationale: The correct answer is B. Diabetes is associated with chronic complications such as retinopathy, neuropathy, and coronary artery disease. Choice A includes symptoms rather than chronic complications of diabetes. Choice C lists conditions not typically associated with diabetes. Choice D describes symptoms that may occur in various medical conditions but are not specific chronic complications of diabetes.

Correct Answer: D

Rationale: The correct answer is D: Undiagnosed, untreated diabetes mellitus. Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is most commonly caused by undiagnosed and untreated diabetes mellitus. Insulin overdose (Choice A) is not a typical cause of HHNS; it is more related to hypoglycemia. Removal of the adrenal gland (Choice B) can lead to adrenal insufficiency but is not a common cause of HHNS. Undiagnosed, untreated hyperpituitarism (Choice C) is not a usual cause of HHNS; it is more related to pituitary hormone imbalances rather than hyperglycemia.

Correct Answer: C

Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.

Correct Answer: A

Rationale: The correct answer is to check the client's serum glucose level. In a client with diabetes who just had surgery, monitoring the serum glucose level is crucial to ensure proper management of the condition. This helps in preventing complications related to blood sugar fluctuations. Assisting the client out of bed may be important but not the primary responsibility at this time. Placing the client in a high-Fowler's position or ensuring the residual limb is elevated are important interventions for comfort and circulation but are not the primary concern in this scenario.
