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. An 8-year-old is placed in 90-90 traction for a fractured femur resulting from a motor vehicle collision. Which finding requires further action by the nurse?

• A. No bowel movement for two days
• B. Mother assists child in changing positions
• C. Weights are touching the foot of the bed
• D. Child is able to move the toes freely when tickled

Correct answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.

3. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

4. A client who had an abdominal hysterectomy is experiencing minimal urine output despite adequate fluid intake. What should the nurse assess first?

• A. The client's bladder for distension.
• B. The IV catheter insertion site.
• C. The patency of the urinary catheter.
• D. The client's vital signs.

Correct answer: C

Rationale: Assessing the patency of the urinary catheter is crucial in this situation. A blocked catheter could be a common cause of decreased urine output following surgery. While checking the IV catheter insertion site (Choice B) is important, it is not the priority in this case. Examining the client's bladder for distension (Choice A) is relevant, but assessing the patency of the catheter takes precedence in resolving the issue of decreased urine output. Monitoring vital signs (Choice D) is a routine nursing task but not the priority when dealing with decreased urine output post-surgery.

5. 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.
