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.

Answer and Explanation

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

Explanation

Choice A rationale
Reviewing serum protein levels can provide valuable information about a client’s nutritional status and liver function. However, in the context of a client with decompensated liver disease who is experiencing fever, chills, and abdominal tenderness, and has a high polymorphonuclear leukocyte count in ascitic fluid, initiating antibiotic therapy is the priority.
Choice B rationale
Beginning abdominal girth measurements can be useful for monitoring the progression of ascites in a client with liver disease. However, in this scenario, the priority is to treat the potential infection indicated by the client’s symptoms and lab results.
Choice C rationale

Initiating antibiotic therapy is the correct intervention in this case. The client’s symptoms and the high polymorphonuclear leukocyte count in the ascitic fluid suggest spontaneous bacterial peritonitis, a serious complication of cirrhosis that requires immediate antibiotic treatment.
Choice D rationale
Assessing neurological status is important in clients with liver disease, as they are at risk for hepatic encephalopathy. However, in this scenario, the priority is to treat the potential infection indicated by the client’s symptoms and lab results.

A. Stabilize the cervical spine. B. Check for a pulse. C. Request an x-ray. D. Assess the respiratory rate. E. Examine the abdomen. F. Ensure the airway is patent.

Correct Answer is ["A","F"]

Explanation

Choice A rationale

Stabilizing the cervical spine is one of the first actions that should be taken during the primary survey of a trauma patient. This is to prevent any potential injury to the spinal cord, which could result in permanent paralysis.

Choice B rationale
Checking for a pulse is an important part of the primary survey, but it is not one of the first actions that should be taken. The first priority is to ensure that the airway is patent and the cervical spine is stabilized.

Choice C rationale
Requesting an x-ray is not one of the first actions that should be taken during the primary survey. The first priority is to assess the client’s airway, breathing, and circulation, and to stabilize the cervical spine.

Choice D rationale
Assessing the respiratory rate is an important part of the primary survey, but it is not one of the first actions that should be taken. The first priority is to ensure that the airway is patent and the cervical spine is stabilized.

Choice E rationale
Examining the abdomen is an important part of the secondary survey, which is conducted after the primary survey. The first priority during the primary survey is to assess the client’s airway, breathing, and circulation, and to stabilize the cervical spine.
Choice F rationale

Ensuring that the airway is patent is one of the first actions that should be taken during the primary survey. This is to ensure that the client is able to breathe effectively and receive adequate oxygenation.
