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 because suction equipment is essential for clearing the airway of secretions or vomitus during or after a seizure. The nurse should have suction equipment ready and accessible at the client's bedside at all times.
Choice B: This is incorrect because backboard is not needed for a client who has a seizure disorder. Backboard is used for immobilizing the spine in case of a suspected spinal injury.
Choice C: This is incorrect because padded tongue blades are not recommended for a client who has a seizure disorder. Padded tongue blades can cause injury to the teeth, gums, or tongue if inserted during a seizure. The nurse should never force anything into the mouth of a client who is having a seizure.
Choice D: This is incorrect because wrist restraints are not indicated for a client who has a seizure disorder. Wrist restraints can cause injury or skin breakdown if applied during a seizure. The nurse should never restrain or restrict the movements of a client who is having a seizure.

Explanation
Choice A reason: Oxybutynin is an anticholinergic drug that relaxes the muscles of the bladder and reduces spasms, urgency, and frequency of urination. It is used to treat overactive bladder and urinary incontinence.
Choice B reason: Oxybutynin does not increase tissue perfusion in the lungs, as it has no effect on the respiratory system. It can actually cause dry mouth, nasal congestion, and blurred vision as side effects.
Choice C reason: Oxybutynin does not increase venous return to the heart, as it has no effect on the cardiovascular system. It can actually cause tachycardia, palpitations, and hypertension as side effects.
Choice D reason: Oxybutynin does not relax the muscles of the colon, as it has no effect on the gastrointestinal system. It can actually cause constipation, nausea, and abdominal pain as side effects.
