A nurse is caring for a client who has diabetes mellitus. Which of the following laboratory findings indicates the client has maintained control of his blood glucose levels for the past 3 months?

The correct answer is A:

Choice A reason:

Replace the unit when the drainage chamber is full. This ensures continuous, effective drainage. A full chamber cannot collect more fluid, risking system compromise and patient safety.

Choice B reason:

Pinning the tubing to the bed sheets is incorrect because it can cause kinks in the tubing, leading to obstruction of drainage and potential complications.

Choice C reason:

Monitoring for at least 150 mL of drainage every hour is not a standard practice. Normal chest tube drainage is variable; excessive drainage, such as 150 mL/hour, could indicate a serious condition like hemorrhage.

Choice D reason:

Clamping the tube routinely for 30 minutes every 8 hours is not recommended. Clamping may be done during tube removal or to check for air leaks but doing so routinely can lead to tension pneumothorax.

The correct answer is C. Consume a diet high in antioxidants.

Choice A: Complete breast self-examinations one week prior to menstruation.

Performing breast self-examinations one week prior to menstruation is not recommended. The best time to perform a breast self-exam is about 3 to 5 days after your period starts, when your breasts are least likely to be tender or swollen. This timing helps in detecting any unusual changes more accurately.

Choice B: Expect clear discharge from the nipples.

While some nipple discharge can be normal, it is not something that should be expected as a routine part of breast health. Clear, yellow, or white discharge can occur due to hormonal changes, but any spontaneous discharge, especially if it is bloody or from one breast, should be evaluated by a healthcare provider.

Choice C: Consume a diet high in antioxidants.

Consuming a diet high in antioxidants is beneficial for overall health and may help reduce the risk of various diseases, including cancer. Antioxidants help neutralize free radicals, which can damage cells and contribute to cancer development. Foods rich in antioxidants include fruits, vegetables, nuts, and whole grains.

Choice D: Include meats grilled over high heat in the diet.

Including meats grilled over high heat in the diet is not advisable for someone concerned about cancer risk. Grilling meats at high temperatures can produce carcinogens such as heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which have been linked to an increased risk of cancer. Therefore, it is better to avoid or limit the consumption of grilled meats.
