The nurse is teaching an adult patient with Type 1 diabetes that a primary cause of the development of diabetic ketoacidosis (DKA) is:

Omitted meals

Polydipsia and polyphagia

Not taking enough insulin

An insulin overdose

Answer and Explanation

The Correct Answer is C

Choice A rationale

Omitted meals can lead to hypoglycemia, not diabetic ketoacidosis (DKA). DKA is caused by a lack of insulin, not a lack of food intake.

Choice B rationale

Polydipsia and polyphagia are symptoms of hyperglycemia, not causes of DKA. They occur as the body tries to compensate for high blood sugar levels.

Choice C rationale

Not taking enough insulin is a primary cause of the development of DKA. Without enough insulin, the body begins to break down fat for fuel, which produces acids known as ketones.

Choice D rationale

An insulin overdose would lead to hypoglycemia, not DKA. DKA is caused by a lack of insulin, not an excess.

Correct Answer is A

Explanation

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. -

A. 30 seconds B. 45 seconds C. 60 seconds D. 75 seconds

Correct Answer is D

Explanation

Step 1 is to understand the therapeutic range for aPTT when a patient is on heparin therapy. The therapeutic range for aPTT is 1.5 to 2.5 times the normal value. Given that the normal aPTT value is around 30-40 seconds, the therapeutic range would be approximately 45-100 seconds. Therefore, an aPTT value of 75 seconds falls within this therapeutic range, indicating that the heparin therapy is effective.
