1. Which natural body defense plays an active role in preventing infection?

• A. Yawning
• B. Body hair
• C. Hiccupping
• D. Rapid eye movements

Correct answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

2. How can preserving skin integrity impact the circular chain of infection?

• A. Host
• B. Reservoir
• C. Mode of transmission
• D. Portal of entry

Correct answer: D

Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.

3. A healthcare provider is caring for a group of clients. Which of the following clients is not at risk for pulmonary embolism?

• A. A client who has a BMI of 30
• B. A female client who is postmenopausal
• C. A client who has a fractured femur
• D. A client who has chronic atrial fibrillation

Correct answer: B

Rationale: Postmenopausal status is not a significant risk factor for pulmonary embolism. Risk factors for pulmonary embolism include obesity (BMI of 30 or higher), immobility such as having a fractured femur, and conditions like chronic atrial fibrillation that increase the risk of blood clot formation. While postmenopausal status may be associated with other health risks, it is not directly linked to an increased risk of pulmonary embolism.

4. A healthcare professional is assessing a client following a gunshot wound to the chest. For which of the following findings should the healthcare professional not monitor to detect a pneumothorax?

• A. Tachypnea
• B. Deviation of the trachea
• C. Bradycardia
• D. Pleuritic pain

Correct answer: C

Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

5. When caring for a client on pressure support ventilation (PSV), which statement by the nurse indicates an understanding of PSV?

• A. It keeps the alveoli open and prevents atelectasis.
• B. It allows preset pressure delivered during spontaneous ventilation.
• C. It guarantees minimal minute ventilator.
• D. It delivers a preset ventilatory rate and tidal volume to the client.

Correct answer: B

Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.
