An adult client newly diagnosed with type 2 diabetes mellitus asks a nurse to explain how he developed the condition. Which of the following responses should the nurse make?

Choice A rationale
Using several different scales to obtain the weight is incorrect. Consistency is key when monitoring weight, especially for clients with chronic kidney disease. Using the same scale ensures that weight measurements are accurate and comparable over time. Different scales may have slight variations, leading to inconsistent and unreliable data.
Choice B rationale
Weighing at the same time each day is correct. It is important to weigh at the same time each day, preferably in the morning after voiding and before eating, to obtain consistent and accurate measurements. This helps in monitoring fluid retention and changes in body weight, which are critical for managing chronic kidney disease.
Choice C rationale
Calibrating weight scales every week is not necessary. While it is important to ensure that the scale is accurate, weekly calibration is excessive. Regular calibration according to the manufacturer’s instructions or as needed is sufficient to maintain accuracy. Over-calibration can be time-consuming and may not significantly improve measurement accuracy.
Choice D rationale
Measuring weight just prior to voiding is incorrect. Weighing after voiding provides a more accurate measurement of body weight without the influence of bladder contents. This is especially important for clients with chronic kidney disease, as fluid balance and retention are closely monitored.

Choice A rationale
Rifampin can cause discoloration of body fluids, including tears, which can stain contact lenses. Therefore, it is recommended to wear glasses instead of contacts while taking this medication.
Choice B rationale
A yellow tint to the skin is not an expected reaction to rifampin. This could indicate jaundice, a sign of liver dysfunction, which requires immediate medical attention.
Choice C rationale

Lifelong treatment with rifampin is not necessary. The typical duration of treatment for active tuberculosis is 6 to 9 months.
Choice D rationale
Rifampin does not cause amenorrhea when taken with oral contraceptives. However, it can reduce the effectiveness of oral contraceptives, so additional contraceptive methods should be used.
