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. In Maslow’s hierarchy of physiological needs, the human need of greatest priority is:

• A. Love
• B. Elimination
• C. Nutrition
• D. Oxygen

Correct answer: D

Rationale: In Maslow’s hierarchy of physiological needs, the most basic and immediate need is physiological survival, which includes the need for oxygen. Without oxygen, the body cannot survive for more than a few minutes, making it the highest priority physiological need according to Maslow's hierarchy.

3. The healthcare professional must verify the client’s identity before the administration of medication. Which of the following is the safest way to identify the client?

• A. Ask the client for their name
• B. Check the client’s identification band
• C. State the client’s name aloud and ask the client to repeat it
• D. Check the room number

Correct answer: B

Rationale: Verifying the client's identity before administering medication is crucial to ensure patient safety. Checking the client’s identification band is the safest and most reliable method to confirm the client's identity. Identification bands are specifically designed to prevent errors in patient identification and help healthcare professionals administer care to the correct individual. Asking the client for their name (Choice A) may lead to errors if the client is unable to communicate or if there is a language barrier. Stating the client’s name aloud and asking them to repeat it (Choice C) relies on the client's ability to respond accurately. Checking the room number (Choice D) does not directly confirm the client's identity and may lead to errors if multiple patients are in the same room.

4. While teaching a newly hired nurse about varicella, a nurse in a pediatric clinic should include which of the following information?

• A. Children who have varicella are contagious until vesicles are crusted.
• B. Children who have varicella should receive the varicella (chickenpox) vaccine.
• C. Children who have varicella should be placed in airborne precautions.
• D. Children who have varicella are contagious 1-2 days before the rash appears.

Correct answer: A

Rationale: Children with varicella (chickenpox) are contagious until all vesicles are crusted over. The contagious period starts 1-2 days before the rash appears and continues until all lesions are dried and crusted. It is important to educate healthcare providers about the contagious period to prevent the spread of the virus to susceptible individuals.

5. A nurse is providing teaching about gastrostomy tube feedings to the parents of a school-age child. Which of the following instructions should the nurse give?

• A. Administer the feeding over 30 minutes
• B. Place the child in a supine position after the feeding
• C. Change the feeding bag and tubing every 3 days
• D. Warm the formula in a warm water bath before administration

Correct answer: B

Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.
