1. What is the primary function of surfactant in the lungs?

• A. Reduce surface tension
• B. Enhance oxygen absorption
• C. Facilitate carbon dioxide release
• D. Increase lung volume

Correct answer: A

Rationale: The primary function of surfactant in the lungs is to reduce surface tension in the alveoli. This reduction in surface tension prevents lung collapse and allows for easier breathing. It is particularly crucial in premature infants to help with lung expansion. Choice B is incorrect because surfactant primarily affects surface tension, not oxygen absorption. Choice C is incorrect because surfactant's main role is not in facilitating carbon dioxide release. Choice D is incorrect because surfactant does not directly increase lung volume; its main role is in reducing surface tension.

2. Which of the following is an appropriate intervention for a patient experiencing a hypertensive crisis?

• A. Placing the patient in a supine position
• B. Administering a beta-blocker intravenously
• C. Encouraging the patient to drink fluids
• D. Applying a cold compress to the forehead

Correct answer: B

Rationale: Administering a beta-blocker intravenously is the correct intervention for a patient experiencing a hypertensive crisis. Beta-blockers help quickly reduce blood pressure and prevent complications such as stroke or heart attack. Placing the patient in a supine position can worsen the condition by reducing venous return and increasing the workload of the heart. Encouraging the patient to drink fluids is not recommended as it can exacerbate hypertension by increasing fluid volume. Applying a cold compress to the forehead does not address the underlying cause of the hypertensive crisis and is unlikely to provide significant benefit.

3. A post-operative client develops a sudden onset of chest pain and dyspnea. The nurse suspects a pulmonary embolism (PE). What is the priority nursing action?

• A. Administer oxygen via face mask.
• B. Elevate the client's legs.
• C. Prepare the client for immediate surgery.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: Administering oxygen via face mask is the priority nursing action in a post-operative client suspected of a pulmonary embolism. This intervention helps ensure adequate oxygenation while further assessments and interventions are initiated. Elevating the client's legs is not indicated for a suspected pulmonary embolism; it is more appropriate for conditions like shock. Immediate surgery is not the priority in this situation as the client is experiencing acute symptoms requiring prompt intervention. While notifying the healthcare provider is important, the immediate focus should be on providing oxygen to the client to support respiratory function.

4. Which task could the PN safely delegate to the UAP?

• A. Oral feeding of a two-year-old child after application of a hip spica cast
• B. Assessment of the placement and patency of a NG tube
• C. Participation in staff rounds to record notes regarding client goals
• D. Evaluation of a client's incisional pain following narcotic administration

Correct answer: A

Rationale: The correct answer is A because oral feeding of a child is a task that can be safely delegated to an unlicensed assistive personnel (UAP). This task involves providing basic care and does not require specialized nursing skills. Choices B, C, and D involve assessments, recording client goals, and evaluating pain, respectively, which all require specialized nursing knowledge, judgment, and skills. These tasks are not within the scope of practice for a UAP.

5. A client who had a right total shoulder replacement is being prepared for discharge. What should the nurse emphasize to the client to prevent complications?

• A. Avoid lifting objects with the right arm until cleared by the surgeon.
• B. Perform shoulder exercises to regain strength.
• C. Use a sling at all times, even during sleep.
• D. Apply heat to the shoulder to reduce stiffness.

Correct answer: A

Rationale: The correct answer is to avoid lifting objects with the right arm until cleared by the surgeon. After a total shoulder replacement, it is essential to protect the new joint to prevent dislocation or injury. Lifting heavy objects prematurely can lead to complications. While performing shoulder exercises is important for strength, they should be done as per the healthcare provider's instructions to avoid strain on the new joint. Using a sling at all times, as in choice C, is not necessary once the client has regained enough strength and mobility. Applying heat, as in choice D, may not be recommended post-surgery; cold therapy is often preferred to reduce swelling and pain.
