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 A
Explanation
Choice A: This is correct. Dehydration can cause electrolyte imbalance and affect the brain function, leading to confusion, dizziness, or lethargy.
Choice B: This is incorrect. Cool, clammy skin is a sign of shock, not dehydration. Dehydration can cause dry, warm skin.
Choice C: This is incorrect. Decrease in pulse rate is a sign of bradycardia, not dehydration. Dehydration can cause increase in pulse rate as the body tries to compensate for the low blood volume.
Choice D: This is incorrect. Increase in blood pressure is a sign of hypertension, not dehydration. Dehydration can cause decrease in blood pressure as the blood volume drops.
Correct Answer is B
Explanation
Choice A: This is incorrect. The nurse should don clean gloves before removing the dressing, and then change to sterile gloves before applying the new dressing.
Choice B: This is correct. The nurse should offer the client pain medication before the procedure, as changing a dressing for a stage III pressure ulcer can be very painful.
Choice C: This is incorrect. The nurse should prepare the sterile dressing supplies just before the dressing change, not 30 min before, to prevent contamination.
Choice D: This is incorrect. The nurse should not disinfect the wound bed with alcohol, as this can damage the healthy tissue and delay healing. The nurse should use a saline solution or an antiseptic solution as prescribed.
