A client asks a nurse, “What is a hemoglobin A1C test?” Which of the following is the most appropriate response?
It evaluates glycemic control over a 3-month period by measuring the glucose attached to hemoglobin.
It uses the level of serum protein to evaluate glycemic control.
It evaluates serum ketone production over several days.
It determines the amount of glucose attached to hemoglobin over the last seven days.
The Correct Answer is A
Choice A rationale
The hemoglobin A1C test, also known as the HbA1C or glycated hemoglobin test, is a blood test that evaluates glycemic control over a 3-month period by measuring the glucose attached to hemoglobin. This test is commonly used to diagnose and monitor diabetes. It provides an average of your blood sugar levels over the past 2-3 months, which can help healthcare providers assess how well diabetes is being managed.
Choice B rationale
The hemoglobin A1C test does not use the level of serum protein to evaluate glycemic control. Instead, it measures the amount of glucose that is attached to the hemoglobin in your red blood cells.
Choice C rationale
The hemoglobin A1C test does not evaluate serum ketone production over several days. Ketones are produced when the body burns fat for energy, which can occur when there is not enough insulin to help your body use sugar for energy. High levels of ketones can lead to diabetic ketoacidosis, a serious condition that requires immediate medical attention.
Choice D rationale
The hemoglobin A1C test does not determine the amount of glucose attached to hemoglobin over the last seven days. Instead, it provides an average of your blood sugar levels over the past 2-3 months. -

Correct Answer is A
Explanation
Choice A rationale
People with Type 1 diabetes have little or no insulin that can be released. This is because their pancreatic β-cells, which produce insulin, are destroyed by an autoimmune process. Without insulin, glucose cannot be taken up into cells to be used for energy. Oral antihyperglycemic agents work by increasing the release of insulin or increasing the body’s sensitivity to insulin, so they are not effective in Type 1 diabetes where there is an absolute insulin deficiency.
Choice B rationale
The cost of oral antihyperglycemic agents is not the primary reason they are not used in Type 1 diabetes. The main issue is the lack of insulin production, which these medications cannot address.
Choice C rationale
People with Type 1 diabetes do not typically have resistance to their endogenous insulin. Insulin resistance is more commonly associated with Type 2 diabetes.
Choice D rationale
While hypoglycemia can occur with the use of some antihyperglycemic agents, this is not the primary reason these medications are not used in Type 1 diabetes. The main issue is the absolute deficiency of insulin.
Correct Answer is A
Explanation
Choice A rationale
Fluid Volume Excess (FVE), or hypervolemia, refers to an isotonic expansion of the ECF due to an increase in total body sodium content and an increase in total body water. This fluid overload usually occurs from compromised regulatory mechanisms for sodium and water as seen commonly in heart failure (CHF), kidney failure, and liver failure. The key signs of hypervolemia include weight gain and swelling. One of the defining characteristics of FVE is an increase in urine specific gravity. Therefore, a urine specific gravity of 1.012 can validate the problem of Fluid Volume Excess for a patient.
Choice B rationale
+4 Pedal pulses indicate a very bounding and strong pulse, which is not directly related to Fluid Volume Excess. While it might be observed in some cases due to increased blood volume and pressure, it is not a specific or primary indicator of this condition.
Choice C rationale
A respiratory rate of 20/minute is within the normal range for an adult (12-20 breaths per minute) and does not specifically indicate Fluid Volume Excess. While respiratory changes can occur with severe or prolonged Fluid Volume Excess, a normal respiratory rate does not validate this diagnosis.
Choice D rationale
A potassium level of 3.8 mEq/L is within the normal range (3.5-5.0 mEq/L) and does not specifically indicate Fluid Volume Excess. While electrolyte imbalances can occur with Fluid Volume Excess, a normal potassium level does not validate this diagnosis.
