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 B
Explanation
Choice A reason: Having a bologna sandwich is not a good choice for a client who has hypertension, as bologna is a processed meat that contains high amounts of sodium and saturated fat, which can raise blood pressure and cholesterol levels.
Choice B reason: Seasoning food with vinegar is a good choice for a client who has hypertension, as vinegar is a low-sodium condiment that can add flavor and acidity to food without increasing blood pressure.
Choice C reason: Seasoning food with ketchup is not a good choice for a client who has hypertension, as ketchup is a high-sodium condiment that can increase blood pressure and fluid retention.
Choice D reason: Having canned soup is not a good choice for a client who has hypertension, as canned soup is a high-sodium food that can increase blood pressure and fluid retention. The client should choose low-sodium or homemade soup instead.
Correct Answer is B
Explanation
Choice A reason: The thigh-high stockings should reach just below the gluteal folds, not above them. If the stockings are too high, they can cause constriction and impair circulation.
Choice B reason: Reapplying the stockings before getting out of bed is an appropriate action. The client should remove the stockings at night and inspect the skin for any signs of irritation or breakdown. The client should also elevate the legs for 15 minutes before putting on the stockings to reduce edema and improve venous return.
Choice C reason: Flexing the toes when applying the stockings is not an appropriate action. The client should point the toes and foot downward when applying the stockings to prevent wrinkles or folds that can cause pressure ulcers.
Choice D reason: Rolling down knee-high stockings slightly to provide comfort is not an appropriate action. The client should avoid rolling or folding the stockings as this can create a tourniquet effect and impair blood flow.
