Nursing Elites

1. A patient is being treated for dehydration. Which lab result would support the diagnosis?

• A. Elevated hemoglobin
• B. Low sodium level
• C. High white blood cell count
• D. Elevated BUN

Correct answer: D

Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.

2. A healthcare provider is reviewing the medical record of a client who has a new prescription for clozapine. Which of the following findings indicates a contraindication to clozapine?

• A. Fasting blood glucose of 120 mg/dL
• B. Asthma
• C. Hypertension
• D. WBC count of 3,300/mm3

Correct answer: D

Rationale: A low WBC count (3,300/mm3) is a contraindication to clozapine because this medication can cause severe neutropenia. Neutropenia is a significant reduction in white blood cell count, increasing the risk of infections. Elevated fasting blood glucose, asthma, and hypertension are not direct contraindications to clozapine.

3. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?

• A. 40 ml/hr
• B. 42 ml/hr
• C. 44 ml/hr
• D. 46 ml/hr

Correct answer: B

Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.

4. Which intervention is most effective in preventing postoperative complications?

• A. Encourage the patient to drink fluids.
• B. Ambulate the patient as soon as possible.
• C. Perform deep breathing exercises with the patient.
• D. Encourage the patient to perform range of motion exercises.

Correct answer: B

Rationale: The most effective intervention in preventing postoperative complications is to ambulate the patient as soon as possible. Early ambulation helps prevent complications like deep vein thrombosis and pneumonia by enhancing circulation and preventing respiratory issues. Encouraging the patient to drink fluids, perform deep breathing exercises, or range of motion exercises are beneficial interventions, but ambulation is the priority due to its overall impact on preventing various postoperative complications.

5. A nurse is planning care for an older adult client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse use to help maintain the integrity of the client's skin?

• A. Elevate the head of the bed no more than 45 degrees
• B. Apply cornstarch to keep sensitive skin areas dry
• C. Massage the skin over the client's bony prominences
• D. Use a transfer device to lift the client up in bed

Correct answer: D

Rationale: The correct answer is to use a transfer device to lift the client up in bed. This intervention helps reduce friction and the risk of skin breakdown, aiding in the prevention of pressure ulcers. Elevating the head of the bed no more than 45 degrees can help with respiratory issues but does not directly address skin integrity. Applying cornstarch may lead to further skin irritation. Massaging over bony prominences can increase the risk of skin damage rather than maintaining skin integrity.
