Nursing Elites

1. How should a healthcare professional position a patient to reduce the risk of pressure ulcers?

• A. Position the patient in the supine position for long periods.
• B. Use pillows to support bony prominences.
• C. Turn the patient every 4 hours.
• D. Place the patient on an alternating pressure mattress.

Correct answer: B

Rationale: Correctly positioning a patient to reduce the risk of pressure ulcers involves using pillows to support bony prominences. This helps to relieve pressure from vulnerable areas and prevent the development of pressure ulcers. Choice A is incorrect because keeping a patient in the supine position for extended periods can increase the risk of pressure ulcers. Choice C is incorrect as turning the patient every 2 hours, rather than every 4 hours, is recommended to prevent pressure ulcers. Choice D is not the best option mentioned for positioning a patient to reduce pressure ulcer risk; although alternating pressure mattresses can be beneficial, using pillows for support is a more direct and commonly used method.

2. 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.

3. A nurse is preparing a client for surgery. Which of the following actions should be taken first?

• A. Ensure informed consent is signed
• B. Start IV fluids
• C. Administer preoperative antibiotics
• D. Reinforce surgical site dressing

Correct answer: A

Rationale: The correct answer is to ensure informed consent is signed first when preparing a client for surgery. This step is crucial as it ensures that the client has been informed about the procedure, risks, benefits, and alternatives before giving consent. Starting IV fluids (choice B) may be necessary but comes after obtaining informed consent. Administering preoperative antibiotics (choice C) is important but typically follows confirming informed consent. Reinforcing surgical site dressing (choice D) is a postoperative step and does not take precedence over obtaining informed consent.

4. A nurse is caring for a client who had a total thyroidectomy and has a serum calcium level of 7.6 mg/dL. Which of the following findings should the nurse expect?

• A. Shortened QT intervals
• B. Hypoactive deep tendon reflexes
• C. Tingling of the extremities
• D. Constipation

Correct answer: C

Rationale: The correct answer is C: Tingling of the extremities. Tingling is a common symptom of hypocalcemia, which is expected with low calcium levels after a thyroidectomy. Option A, shortened QT intervals, is associated with hypercalcemia rather than hypocalcemia. Option B, hypoactive deep tendon reflexes, is not typically related to hypocalcemia. Option D, constipation, is not a common finding associated with low calcium levels.

5. A client with pneumonia is receiving oxygen therapy. Which of the following oxygen delivery devices should be used to deliver a precise oxygen concentration?

• A. Nasal cannula
• B. Simple face mask
• C. Venturi mask
• D. Non-rebreather mask

Correct answer: C

Rationale: A Venturi mask should be used to deliver a precise oxygen concentration to a client with pneumonia. Venturi masks are designed to deliver a specific oxygen concentration by mixing oxygen with room air in a precise ratio. This device is ideal for patients who require accurate oxygen delivery, such as those with chronic lung diseases. Nasal cannulas deliver a lower concentration of oxygen and are more suitable for patients with mild respiratory issues. Simple face masks and non-rebreather masks do not provide as precise control over the oxygen concentration as a Venturi mask.
