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. You are teaching students about how hyperosmotic agents (osmotic diuretics) are used to treat intracranial pressure. Which of the following is NOT one of the functions of hyperosmotic agents?

• A. Reduces brain metabolism and systemic blood pressure
• B. Reduces cerebral edema
• C. Dehydrates the brain
• D. Draws fluids from extravascular spaces into the plasma

Correct answer: A

Rationale: Hyperosmotic agents primarily work by reducing cerebral edema, dehydrating the brain, and drawing fluids from extravascular spaces into the plasma. However, they do not have a direct effect on reducing brain metabolism or systemic blood pressure. Therefore, the correct answer is A. Choice B is correct as hyperosmotic agents do help in reducing cerebral edema. Choice C is accurate as hyperosmotic agents dehydrate the brain. Choice D is also true as these agents draw fluids from extravascular spaces into the plasma.

3. A client on bedrest refuses to wear the prescribed pneumatic compression devices after surgery. Which action should the PN implement in response to the client's refusal?

• A. Emphasize the importance of active foot flexion
• B. Check the surgical dressing
• C. Complete an incident report
• D. Explain the use of an incentive spirometer every 2 hours

Correct answer: A

Rationale: The correct action for the PN to implement when a client refuses pneumatic compression devices is to emphasize the importance of active foot flexion. Active foot flexion exercises can help prevent deep vein thrombosis (DVT) in clients who are not using the compression devices. Encouraging some form of circulation-promoting activity is crucial to reduce the risks associated with immobility. Checking the surgical dressing (Choice B) is important but not the immediate action to address the refusal of compression devices. Completing an incident report (Choice C) is not necessary in this situation as the client's refusal is not an incident. Explaining the use of an incentive spirometer (Choice D) is not directly related to addressing the refusal of compression devices for DVT prevention.

4. The PN is assisting the recreational director of a long-term care facility to plan outdoor activities for wheelchair-bound older residents who are mentally alert. Which activity meets the physical and social needs of these residents?

• A. An open-air concert
• B. A tea party in the courtyard
• C. A team ring-toss competition
• D. A picnic in the park

Correct answer: B

Rationale: A tea party in the courtyard is the most suitable activity as it allows for social interaction in a comfortable and accessible environment. Wheelchair-bound residents can easily participate, fostering both physical and social engagement. An open-air concert may pose challenges regarding accessibility and comfort for wheelchair-bound individuals. A team ring-toss competition involves physical activity that may not be inclusive for all residents, especially those in wheelchairs. A picnic in the park may also present challenges related to accessibility and comfort for wheelchair-bound individuals.

5. While ambulating in the hallway following an appendectomy yesterday, a client complains of chest tightness and shortness of breath. Which action should the nurse implement first?

• A. Administer sublingual nitroglycerin
• B. Assist the client back to the room
• C. Have the client sit down in the hall
• D. Obtain a 12-lead electrocardiogram

Correct answer: C

Rationale: Having the client sit down in the hallway is the first action the nurse should implement. This is crucial to prevent further strain on the heart and to provide a safer environment for assessment and potential emergency intervention. Administering sublingual nitroglycerin (Choice A) may be appropriate later but should not precede ensuring the client's immediate safety. Assisting the client back to the room (Choice B) may not be advisable if the client is experiencing chest tightness and shortness of breath. Obtaining a 12-lead electrocardiogram (Choice D) is important but would not be the initial action to address the client's immediate symptoms.
