A client who is postmenopausal, obese, and is a smoker, has developed an intolerance to fatty foods and believes she is at risk for developing gallbladder problems. Which instruction should the nurse provide to help reduce the client's risk for gallbladder disease?

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: Palpating the lymph nodes is not a standard technique for assessing early signs of rheumatoid arthritis. Lymph node enlargement can occur due to various reasons, but it is not specific to rheumatoid arthritis.

Choice B reason: Observing the client's fingers is crucial because early signs of rheumatoid arthritis often present in the small joints of the hands and fingers. Symptoms such as swelling, redness, stiffness, and deformities can be evident in these areas.

Choice C reason: Observing the skin for lesions is not specific to rheumatoid arthritis. While some skin conditions can be associated with autoimmune diseases, rheumatoid arthritis primarily affects the joints.

Choice D reason: Palpating large joints for nodules might be relevant in more advanced stages of rheumatoid arthritis, but early signs are typically observed in the small joints of the hands and fingers.
