Question 1 of 5
The nurse is caring for a client with a history of type 2 diabetes who is receiving metformin (Glucophage) 500 mg PO bid. Which of the following laboratory results would be of GREATest concern to the nurse?
Correct Answer: A
Rationale: A creatinine of 2.0 mg/dL indicates renal impairment, increasing the risk of lactic acidosis with metformin, requiring immediate evaluation. Options B, C, and D are less concerning: A1c 7.0% shows fair control, potassium 4.0 mEq/L is normal, and glucose 120 mg/dL is acceptable.
Question 2 of 5
The nurse is teaching a client with a new diagnosis of hypothyroidism about levothyroxine (Synthroid). Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: Chest pain may indicate overstimulation from levothyroxine, mimicking hyperthyroidism. Options A, C, and D are incorrect: morning dosing is preferred, stopping the medication risks relapse, and calcium supplements should be avoided but are secondary.
Question 3 of 5
A postoperative client has pain medication ordered PRN for discomfort. During the first assessment, the nurse notes that the client has not received pain medication all day. His vital signs are within normal limits, but he is sweating profusely. He smiles at you while speaking and states that he is not hot but is still experiencing some pain and has been since early this morning. What is the most appropriate nursing action?
Correct Answer: B
Rationale: Administering the minimum dose and reassessing ensures effective pain management while monitoring response, given diaphoresis and reported pain.

Correct Answer: D
Rationale: Checking vital signs and oxygen saturation assesses the cause of symptoms (e.g., hypoxia, hypercapnia). Increasing O2 risks CO2 retention in COPD. Monitoring is passive. Humidity is secondary.
