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?
HbA1c 6.5%
HbA1c 12.5%
Fasting blood glucose 100 mg/dL
Fasting blood glucose 70 mg/dL
The Correct Answer is A
Choice A reason: HbA1c or glycated hemoglobin is a measure of average blood glucose levels over the past 2 to 3 months. A lower HbA1c indicates better glycemic control and a lower risk of diabetes complications. The target HbA1c for most people with diabetes mellitus is less than 7%.
Choice B reason: HbA1c 12.5% is very high and indicates poor glycemic control and a high risk of diabetes complications, such as retinopathy, nephropathy, or neuropathy.
Choice C reason: Fasting blood glucose 100 mg/dL is within the normal range of 70 to 99 mg/dL and indicates normal glucose metabolism, but it does not reflect the long-term control of blood glucose levels over the past 3 months.
Choice D reason: Fasting blood glucose 70 mg/dL is at the lower end of the normal range and may indicate hypoglycemia or low blood glucose levels, which can cause symptoms such as sweating, trembling, hunger, or confusion.

Correct Answer is D
Explanation

Choice C reason: Yogurt is a dairy product that contains protein and calcium but little or no fiber.

Correct Answer is C
Explanation
Choice A: This is incorrect because placing the client in the Sims' position is not necessary for a colposcopy. The nurse should place the client in the lithotomy position, which allows better visualization of the cervix and vagina.
Choice B: This is incorrect because inserting a tampon following the procedure can interfere with healing and increase the risk of infection. The nurse should instruct the client to avoid using tampons, douches, or vaginal creams for at least a week after the procedure.
Choice C: This is correct because instructing the client to avoid sexual intercourse until the cervix is healed can prevent bleeding, infection, and trauma to the cervix. The nurse should advise the client to abstain from sexual activity for at least a week or until advised by the provider.
Choice D: This is incorrect because reinforcing teaching that the procedure involves dilation of the cervix can cause anxiety and discomfort for the client. The nurse should explain that the procedure does not require dilation of the cervix, but rather involves applying a speculum and using a microscope to examine the cervix and take tissue samples if needed.
