Nursing Elites

1. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?

• A. pH level of 7.45
• B. Serum calcium of 15 mg/dL
• C. Blood glucose of 450 mg/dL
• D. Sodium level of 120 mEq/L

Correct answer: C

Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.

2. A client with hypothyroidism is prescribed levothyroxine. What instruction should the nurse provide?

• A. Take the medication in the morning before eating.
• B. Take the medication with a full glass of water.
• C. Take the medication with food to avoid nausea.
• D. Take the medication only when symptoms worsen.

Correct answer: A

Rationale: The correct answer is A: 'Take the medication in the morning before eating.' Levothyroxine should be taken on an empty stomach in the morning for optimal absorption. Choice B is incorrect because while taking medication with water is generally recommended, levothyroxine specifically needs to be taken on an empty stomach. Choice C is incorrect as taking levothyroxine with food can interfere with its absorption. Choice D is incorrect as levothyroxine should be taken regularly as prescribed, not only when symptoms worsen.

3. A client is scheduled for a colonoscopy. Which preparation is the most important for the nurse to implement?

• A. Administer an enema before the procedure.
• B. Ensure the client is NPO after midnight.
• C. Encourage the client to drink clear liquids.
• D. Verify the client has completed the bowel preparation.

Correct answer: D

Rationale: The correct answer is to verify that the client has completed the bowel preparation. This step is crucial to ensure the colon is clear for accurate visualization during the procedure. Administering an enema before the procedure may not always be necessary and can be uncomfortable for the client. Ensuring the client is NPO after midnight is important, but verifying bowel preparation takes precedence. Encouraging the client to drink clear liquids is a part of the preparation process but not the most critical step compared to verifying completion of bowel preparation.

4. The nurse identifies an electrolyte imbalance, a weight gain of 4.4 lbs in 24 hours, and an elevated central venous pressure for a client with full-thickness burns. Which intervention should the nurse implement?

• A. Administer diuretics
• B. Review urine output
• C. Auscultate for irregular heart rate
• D. Increase oral fluid intake

Correct answer: C

Rationale: An elevated CVP and sudden weight gain indicate fluid overload, which can strain the heart. Auscultating for an irregular heart rate is crucial as electrolyte imbalances and fluid shifts after burns can lead to cardiac complications. Monitoring the heart rate is a priority to detect any cardiac distress early. While reviewing urine output and administering diuretics are important interventions, they should come after ensuring the client's cardiac status is stable. Increasing oral fluid intake may exacerbate the fluid overload, making it an inappropriate intervention in this scenario.

5. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.
