A client with diabetic ketoacidosis (DKA) is receiving an IV infusion of 0.9% sodium chloride and insulin.
Two hours later, the client’s serum laboratory results show a decrease in the serum blood glucose from 580 to 430 mg/dL (32.2 to 23.86 mmol/L). What additional laboratory result is most important for the nurse to monitor?
Serum sodium.
Serum potassium.
Blood urea nitrogen (BUN).
Urine ketones.
The Correct Answer is B
Choice A rationale
While monitoring serum sodium levels is important in a client with DKA, it is not the most critical. Hyperglycemia can lead to a state of effective osmotic diuresis, which can cause sodium depletion.
Choice B rationale
Serum potassium levels are crucial to monitor in a client with DKA3. Despite total body potassium depletion, serum potassium levels may be high or normal upon presentation due to acidosis and insulin deficiency. However, with insulin treatment, potassium will shift back into the cells, potentially leading to life-threatening hypokalemia.
Choice C rationale
Blood urea nitrogen (BUN) might be elevated due to dehydration, but it is not the most critical lab value to monitor in the management of DKA3.
Choice D rationale
Urine ketones are not as important to monitor as serum potassium in DKA. The presence of ketones in urine only confirms that the body is breaking down fat, not the severity of DKA3.

Correct Answer is A
Explanation
Choice A rationale
Hyperventilation leads to a decrease in the amount of carbon dioxide (CO2) in the blood. This causes the pH of the blood to increase, resulting in respiratory alkalosis.
Choice B rationale
Respiratory acidosis is caused by a buildup of CO2 in the blood, typically due to hypoventilation (under-breathing). This is not consistent with the patient’s symptoms of hyperventilation.
Choice C rationale
Metabolic alkalosis is typically caused by a significant loss of acid from the body, such as from prolonged vomiting. This is not consistent with the patient’s symptoms.
Choice D rationale
Metabolic acidosis is typically caused by an increase in acid production within the body or a loss of bicarbonate from the body, such as in diabetic ketoacidosis or kidney disease. This is not consistent with the patient’s symptoms.
Correct Answer is A
Explanation
Choice A rationale
The symptoms described - right-sided numbness and weakness in the arm and leg, along with a distinct droop on the right side of the face - are indicative of a stroke. Immediate medical intervention is crucial in such cases. Initiating two large-bore IV catheters would allow for rapid administration of necessary medications and fluids. Reviewing the inclusion criteria for IV fibrinolytic therapy is also important, as this type of therapy can help dissolve the clot causing the stroke and restore blood flow to the brain.
Choice B rationale
While continuous observation for transient episodes of neurological dysfunction is important in the care of a patient with suspected stroke, it is not the first course of action. Immediate medical intervention to treat the stroke is the priority.
Choice C rationale
Elevating the head of the bed to 30 degrees can help reduce intracranial pressure in a patient with a stroke. However, this is not the first course of action. Immediate medical intervention to treat the stroke is the priority.
Choice D rationale
Administering aspirin can help prevent further clot formation and platelet aggregation in patients with certain types of stroke. However, aspirin is not typically the first line treatment in the acute phase of a stroke, especially when the type of stroke (ischemic or hemorrhagic) has not yet been determined.
