Cardiac monitoring is initiated for a patient with diabetic ketoacidosis. The nurse determines that this measure is important to identify:
Electrocardiographic (ECG) changes and dysrhythmias related to hypokalemia.
The presence of hypovolemic shock related to osmotic diuresis.
Cardiovascular collapse resulting from the effects of hyperglycemia.
Fluid overload resulting from aggressive fluid replacement.
The Correct Answer is A
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.

Correct Answer is D
Explanation
This is a critical finding that could indicate bleeding or compromised airway, both of which are potentially life-threatening complications following a thyroidectomy. Immediate intervention may be necessary to prevent further harm to the patient. The other options are important to note and should be addressed, but they do not require immediate intervention as the swelling in the neck does.
Correct Answer is B
Explanation
Based on the given documentation, the nurse suspects that the client has respiratory alkalosis. The client's ABG results show a pH of 7.52, which indicates alkalosis and the PaO2 level is slightly low, suggesting respiratory involvement. Rapid breathing (RR44) and wheezing also support the possibility of respiratory alkalosis.
