1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. How many ounces are in 1 cup?

• A. 8
• B. 80
• C. 800
• D. 8000

Correct answer: A

Rationale: 1 cup is equivalent to 8 ounces. This conversion is commonly used in cooking and baking recipes, where precise measurements are crucial for the successful outcome of dishes. Knowing this conversion helps ensure that ingredients are accurately measured and the recipe turns out as intended. Choices B, C, and D are incorrect because they do not reflect the correct conversion between cups and ounces. 80, 800, and 8000 ounces are significantly higher quantities than what is found in 1 cup, which is 8 ounces.

3. When is sterile technique used?

• A. During strict isolation procedures
• B. After terminal disinfection is performed
• C. For invasive procedures
• D. When protective isolation is necessary

Correct answer: C

Rationale: Sterile technique is utilized during invasive procedures to prevent the introduction of pathogens, minimizing the risk of infections. This strict approach ensures that the procedure is performed in a sterile environment, reducing the chances of contamination and subsequent complications.

4. During a client's first hospitalization, which of the following actions ensures the safety of the client?

• A. Keep unnecessary furniture out of the way
• B. Keep the lights on at all times
• C. Keep side rails up at all times
• D. Keep all equipment out of view

Correct answer: A

Rationale: During a client's first hospitalization, it is essential to keep unnecessary furniture out of the way to prevent obstacles and ensure a safe environment. This action helps reduce the risk of accidents or falls, promoting the client's safety and well-being. Keeping the lights on at all times may not be necessary and can disrupt the client's rest. Keeping side rails up at all times can restrict the client's movement and independence unnecessarily. Keeping all equipment out of view may hinder the healthcare team's ability to monitor and access necessary tools for providing care.

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.
