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 ["C","D","E"]
Explanation
Choice A rationale
Chills and fever are not typically associated with preeclampsia. They are more commonly seen in infections.
Choice B rationale
Lack of appetite is a non-specific symptom and can be associated with many conditions, but it is not a key indicator of preeclampsia.
Choice C rationale
Swollen hands can be a symptom of preeclampsia. This condition can cause sudden weight gain and swelling (edema), particularly in your face and hands.
Choice D rationale
Headaches are a common symptom of preeclampsia. They are often severe and may be accompanied by changes in vision.
Choice E rationale
Blurred vision is a symptom of preeclampsia. Other vision changes, such as sensitivity to light or temporary loss of vision, can also occur.
Choice F rationale
Frequent urination is not typically associated with preeclampsia. It is a common symptom in early and late pregnancy due to the growing uterus pressing on the bladder.
Correct Answer is C
Explanation
Choice A rationale
While avoiding exposure to large crowds can help prevent infections, especially for patients with compromised immune systems, it is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.
Choice B rationale
While emotional support is important for patients dealing with health issues, calling a crisis hotline if feeling lonely is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.
Choice C rationale
This is the most crucial information for the patient. Acetaminophen is found in many over-the- counter medications, and further intake could exacerbate liver damage.
Choice D rationale
While a balanced diet is important for overall health, following a high carbohydrate, low fat, low protein diet is not the most crucial information for a patient with liver damage due to an overdose of acetaminophen.
