An older adult male client tells the nurse of losing sleep because of having to get up several times at night to go to the bathroom. The client also reports having trouble starting his urinary stream, and he does not feel like his bladder is ever completely empty. Which intervention should the nurse implement?

Choice A reason: Obtaining a fingerstick glucose every 6 hours is important for monitoring blood glucose levels and ensuring they are within the target range. However, it is not the most critical intervention for preventing diabetic ketoacidosis. Testing for ketones provides more specific information on the development of DKA.

Choice B reason: Ensuring IV fluids are infusing continuously is crucial for maintaining hydration and preventing electrolyte imbalances, particularly in a client who may be at risk for DKA. However, this intervention is supportive and not as directly related to detecting the onset of DKA as testing for ketones.

Choice C reason: Testing urine for the presence of ketones is the most important intervention. The presence of ketones indicates that the body is breaking down fat for energy instead of using glucose, which is a hallmark of diabetic ketoacidosis. Early detection of ketones allows for prompt intervention to prevent the progression of DKA.

Choice D reason: Teaching the client how to manage sick days is essential for long-term diabetes management and preventing complications during illness. However, for the immediate prevention of DKA in the hospital setting, testing for ketones is more urgent and directly related to detecting and managing the condition.

Choice A reason: Pacing the client's care to provide periods of rest is important for managing fatigue and preventing overexertion. However, it is not the first action the nurse should take in this situation. Monitoring vital signs is crucial to assess the client's current condition and detect any immediate complications.

Choice B reason: Making arrangements for radioactive iodine therapy is a treatment option for hyperthyroidism. However, this is not the first action the nurse should take. The nurse needs to assess the client's condition and stabilize any immediate issues before considering long-term treatment options.

Choice C reason: Administering a beta-adrenergic blocking agent can help manage symptoms such as a racing heartbeat and nervousness. While this may be part of the treatment plan, it is not the first action the nurse should take. Monitoring vital signs is essential to determine the appropriate interventions.

Choice D reason: Monitoring the client's vital signs frequently is the first action the nurse should take. This helps assess the client's current condition, detect any immediate complications, and guide further interventions. It is crucial to ensure the client's stability before implementing other care measures.
