A with acute Gl bleeding is receiving normal saline IV at a rate of 500 ml/hr. Which assessment data obtained by the nurse are most important to communicate immediately to the healthcare provider?

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.

Before administering any medication, the nurse should confirm the potassium level to ensure that it is still elevated and needs to be treated. Potassium levels can fluctuate, so repeating the test will ensure that the client receives the appropriate treatment.

Options (a) Withhold the medication and (b) Administering a hypertonic solution may be appropriate interventions depending on the client's condition, but confirming the potassium level is the first step.

Option (d) Monitoring for paresthesia is important but not the first action that the nurse should take.
