Nursing Elites

1. 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.

2. When administering IV fluids to a dehydrated patient, what is the nurse's priority assessment?

• A. Monitor the patient's electrolyte levels.
• B. Assess the patient's blood pressure regularly.
• C. Monitor the patient's heart rate every 4 hours.
• D. Check the patient's urine output hourly.

Correct answer: B

Rationale: The correct answer is to assess the patient's blood pressure regularly. Monitoring blood pressure is crucial when administering IV fluids to a dehydrated patient as it helps in evaluating the patient's fluid status. Changes in blood pressure can indicate the effectiveness of the fluid therapy, the patient's response to treatment, and the possibility of complications such as fluid overload or hypovolemia. Monitoring electrolyte levels (Choice A) is essential but not the priority when assessing a dehydrated patient receiving IV fluids. Heart rate (Choice C) should be monitored more frequently than every 4 hours in such a situation. Checking urine output (Choice D) is important but not as critical as assessing blood pressure in this scenario.

3. A client is about to undergo surgery and is unsure about the procedure despite signing the consent. What should the nurse do?

• A. Reassure the client and proceed with the surgery.
• B. Stop the surgery and consult with the surgeon.
• C. Proceed with the surgery but document the client's concerns.
• D. Postpone the surgery until further clarification is provided.

Correct answer: B

Rationale: When a client expresses doubts about a procedure after signing the consent form, it is crucial to stop the surgery and consult with the surgeon. This is important to ensure that the client's concerns are addressed, and there is a clear understanding of the procedure. Reassuring the client and proceeding with the surgery (choice A) may violate the client's autonomy and right to informed consent. Proceeding with the surgery but documenting the concerns (choice C) is not sufficient as the client's doubts should be resolved before proceeding. Postponing the surgery until further clarification is provided (choice D) may be necessary, but the immediate step should be to consult with the surgeon to address the client's concerns.

4. The nurse is working on an orthopedic rehabilitation unit that requires lifting and positioning of patients. Which personal injury will the nurse most likely try to prevent?

• A. Hip
• B. Back
• C. Arm
• D. Ankle

Correct answer: B

Rationale: The correct answer is B: Back. Back injuries are most common during lifting and bending tasks, especially in an orthopedic unit. When lifting or repositioning patients, nurses must prioritize proper body mechanics to prevent strain on the back. Choices A, C, and D are less likely to occur as frequently as back injuries in this scenario because of the nature of the tasks involved in orthopedic patient care.

5. 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.
