A client with type 2 diabetes mellitus is receiving metformin (Glucophage). Which laboratory test should the LPN/LVN monitor while the client is taking this medication?

Correct Answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

Correct Answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

Correct Answer: C

Rationale: Having a dental examination every 6 months is crucial for young adult males as it helps in maintaining good oral health and detecting any potential issues early on. Tetanus booster every 10 years is recommended for adults, not every 5 years (Choice A). Herpes zoster immunization is typically recommended for individuals aged 60 and older, not by age 50 (Choice B). While testicular self-examination is important for detecting testicular cancer, routine clinical testicular examinations are not generally needed every 2 years (Choice D). Therefore, the correct answer is to have a dental examination every 6 months.

Correct Answer: B

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. Kinks in the tubing can lead to urine retention or obstruction, increasing the risk of infection. Changing the catheter every 72 hours is not necessary if there are no signs of infection or other issues. Cleaning the perineal area with antiseptic solution daily is important for hygiene but not the most critical action to prevent infection related to the catheter. Irrigating the catheter with normal saline every shift is not a routine practice and may increase the risk of introducing pathogens into the urinary system.

Correct Answer: D

Rationale: The correct answer is D: 'Clear liquids.' Clients with dysphagia following a stroke are at risk of aspiration, and clear liquids have a higher risk of aspiration compared to thickened liquids or pureed foods. Therefore, the nurse should clarify the prescription for clear liquids to prevent potential harm to the client. Choices A, B, and C are appropriate interventions for a client with dysphagia following a stroke. A dietitian consult can help modify the client's diet for safe swallowing, speech therapy can assist in improving swallowing function, and oral suction at the bedside helps maintain airway patency and prevents aspiration.
