A program of weight loss and exercise is recommended for a patient with impaired fasting glucose (IFG). When teaching the patient about the reason for these lifestyle changes, the nurse will tell the patient that:

The onset of diabetes and the associated cardiovascular risks can be delayed or prevented by weight loss and exercise.

Although the fasting plasma glucose levels do not currently indicate diabetes, the glycosylated hemoglobin will be elevated.

The high insulin levels associated with this syndrome damage the lining of blood vessels leading to vascular disease.

The liver is producing excessive glucose, which will eventually exhaust the ability of the pancreas to produce insulin, and exercise will normalize glucose production.

Answer and Explanation

The Correct Answer is A

This statement is correct. Impaired fasting glucose (IFG) is a condition in which the fasting blood glucose level is higher than normal but not high enough to be diagnosed as diabetes. However, people with IFG are at increased risk of developing type 2 diabetes and cardiovascular disease. Weight loss and exercise can help to prevent or delay the onset of diabetes and reduce the risk of cardiovascular disease.

Correct Answer is A

Explanation

Electrocardiographic (ECG) changes and dysrhythmias related to hypokalemia are the main reasons for initiating cardiac monitoring in patients with diabetic ketoacidosis. In diabetic ketoacidosis, insulin deficiency causes the body to break down fat for energy, leading to the production of ketones and resulting in metabolic acidosis. In addition, glucose and potassium are lost in the urine due to osmotic diuresis. Hypokalemia can cause ECG changes and dysrhythmias, which can be life-threatening.

Hypokalemia is a common complication of DKA and can lead to ECG changes such as ST-segment depression, T-wave inversion, and U waves².

Hypovolemic shock related to osmotic diuresis is an important consideration in the management of diabetic ketoacidosis, but it is not the primary reason for initiating cardiac monitoring.

Cardiovascular collapse resulting from the eﬀects of hyperglycemia is not a common complication of diabetic ketoacidosis, and it is not the primary reason for initiating cardiac monitoring.

Fluid overload resulting from aggressive ﬂuid replacement is a potential complication of diabetic ketoacidosis, but it is not the primary reason for initiating cardiac monitoring.

A. The patient has a urine output of 800 ml/hr. B. The patient is confused and lethargic. C. The patient's urine specific gravity is 1.003. D. The patient had a recent head injury.

Correct Answer is B

Explanation

Diabetes insipidus is a condition where the body is not able to regulate water balance properly, leading to excessive urine output and dehydration. The patient's urine output of 800 ml/hr (option A) and low urine specific gravity of 1.003 (option C) is consistent with diabetes insipidus and requires monitoring, but they are not as immediately concerning as the patient's confusion and lethargy.

Confusion and lethargy may indicate severe dehydration, electrolyte imbalances, or even brain swelling (if the patient had a recent head injury, as mentioned in option D). These symptoms require immediate attention to prevent further complications and ensure the patient's safety.
