Nursing Elites

1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

2. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?

• A. Endotracheal cuff pressure greater than 25 cm H2O.
• B. Decreased lung compliance during ventilation.
• C. Bilateral crackles with increased secretions.
• D. Restless client who is biting the endotracheal tube.

Correct answer: D

Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.

3. After placement of a left subclavian central venous catheter (CVC), the nurse receives a report of the X-ray findings indicating that the CVC tip is in the client's superior vena cava. Which action should the nurse implement?

• A. Remove the catheter and apply direct pressure for 5 minutes.
• B. Initiate intravenous fluids as prescribed.
• C. Secure the catheter using aseptic technique.
• D. Notify the healthcare provider of the need to reposition the catheter.

Correct answer: B

Rationale: Initiating intravenous fluids as prescribed is the appropriate action when the CVC tip is correctly placed in the superior vena cava. Intravenous fluids can now be administered effectively through the central line. Removing the catheter and applying direct pressure is unnecessary and not indicated as the tip is in the correct position. Securing the catheter using aseptic technique is important for preventing infections but is not the immediate action needed in this situation. Notifying the healthcare provider of the need to reposition the catheter may delay necessary fluid administration, which is the priority at this time.

4. Before administration of a stat dose of potassium chloride IV for a client with hypokalemia, what is the most important action for the nurse?

• A. Ensure the IV is flowing freely
• B. Mix the medication thoroughly
• C. Check the client’s electrolyte levels
• D. Obtain a baseline ECG

Correct answer: A

Rationale: The most crucial action for the nurse before administering a stat dose of potassium chloride IV to a client with hypokalemia is to ensure the IV is flowing freely. A freely flowing IV is essential to safely and effectively deliver potassium chloride, helping to prevent infusion-related issues. Checking the client's electrolyte levels or obtaining a baseline ECG may be important but are not the most critical actions before administering the medication. Mixing the medication thoroughly is not applicable in this scenario as potassium chloride is typically provided ready to use.

5. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?

• A. Determine if the drainage has an unpleasant odor.
• B. Monitor the client's white blood cell count (WBC).
• C. Request a culture and sensitivity of the wound.
• D. Cleanse the wound with a sterile saline solution.

Correct answer: C

Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.
