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 ["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.

A. Chest x-ray B. Run 0.9% sodium chloride IV infusion at 150 mL/hour C. Sputum culture D. Start oxygen 3 L/minute via nasal cannula E. Start a peripheral IV F. Acetaminophen 350 mg PO every 6 hours for temperature greater than 38.3° C .

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

Explanation

Choice A rationale
A chest x-ray is a critical diagnostic tool for a patient presenting with flu-like symptoms, fever, chest congestion, and increased breathing difficulties. It can help identify conditions such as pneumonia or other lung diseases, which could be causing the patient’s symptoms.
Choice B rationale
While hydration is important, running a 0.9% sodium chloride IV infusion at 150 mL/hour is not the most immediate need for this patient. The patient’s symptoms are primarily respiratory, and there is no indication of dehydration.
Choice C rationale
A sputum culture could be useful for diagnosing bacterial infections of the respiratory tract. However, it is not the most immediate need for this patient, as the results of a culture test can take time to come back.
Choice D rationale
This is the correct answer. Given the patient’s increased breathing difficulties, starting oxygen therapy can help improve the patient’s oxygen levels and ease their breathing.
Choice E rationale

Starting a peripheral IV might be necessary for administering medications or fluids, but it is not the most immediate need in this scenario.
Choice F rationale
While controlling the patient’s fever is important, it is not as immediate a need as performing a chest x-ray and starting oxygen therapy.
