A client with type 1 diabetes mellitus (DM) is admitted to the hospital for an emergency cholecystectomy. The client explains to the nurse about experiencing difficulty at home in keeping blood glucose levels under 200 mg/dl (11.1 mmol/L). To prevent the client from developing diabetic ketoacidosis (DKA), which intervention is most important for the nurse to include in the plan of care?
a) Obtain a fingerstick glucose every 6 hours.
b) Ensure IV fluids are infusing continuously.
c) Test urine for the presence of ketones.
d) Teach the client how to manage sick days.

The correct answer is: c) Test urine for the presence of ketones.

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 DK

Choice A reason: Lifting weights every other day might not be harmful, but it is not specifically relevant to managing chronic venous insufficiency. The statement does not indicate an understanding of the specific care needed for this condition.

Choice B reason: Avoiding sitting and crossing the legs is an important measure to prevent worsening of chronic venous insufficiency. Crossing legs can impede blood flow and worsen symptoms. This statement reflects an understanding of how to manage the condition.

Choice C reason: Standing for prolonged periods, even if there is no pain, can exacerbate venous insufficiency. This statement shows a misunderstanding of the importance of movement and elevation of the legs to promote blood flow.

Choice D reason: Walking is generally encouraged to promote circulation in clients with venous insufficiency. The statement about needing someone else to walk the dog may indicate a misunderstanding of the benefits of regular, gentle exercise.

Choice A reason: Sending the client to x-ray for a flat plate of the abdomen is important for diagnosing the underlying cause of symptoms, such as bowel obstruction or severe inflammation. However, in the immediate situation, it is essential to relieve the client's symptoms and stabilize their condition first.

Choice B reason: Giving a prescribed analgesic for temperature above 101°F (38.3°C) can help manage fever and pain. However, it is not the first priority. The client’s primary issue is abdominal cramping, nausea, and vomiting, which need to be addressed urgently to prevent further complications.

Choice C reason: Placing an indwelling urinary catheter and attaching it to a bedside drainage unit may be necessary if there are urinary retention concerns. However, this intervention does not directly address the gastrointestinal symptoms that are currently most troubling for the client.

Choice D reason: Inserting a nasogastric tube (NGT) and attaching it to low intermittent suction is the most immediate priority. This action helps to decompress the stomach, relieve nausea and vomiting, and prevent further complications such as aspiration or worsening of the obstruction. It provides immediate symptomatic relief and allows for better management of the client's condition.
