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. When applying Nagele's rule, a healthcare professional is estimating a client's expected date of delivery based on their last menstrual period, which began on April 12th. What date should the healthcare professional determine to be the client's expected delivery date? (Use mmdd format.)

• A. 119
• B. 121
• C. 115
• D. 122

Correct answer: A

Rationale: To calculate the expected delivery date using Nagele's rule, begin by subtracting 3 months from the first day of the last menstrual period (April 12th), which results in January 12th. Then, add 7 days. Therefore, the expected delivery date would be January 19th (0119). This calculation method helps healthcare professionals estimate the client's due date.

3. When providing mouth care to an unconscious client, what is the best position for the client?

• A. Fowler’s position
• B. Side-lying
• C. Supine
• D. Trendelenburg

Correct answer: B

Rationale: The best position for an unconscious client when providing mouth care is the side-lying position. This position helps prevent aspiration by allowing fluids to drain out of the mouth easily, reducing the risk of choking or aspiration pneumonia. Placing the client in a side-lying position also promotes comfort and safety during the procedure. The other options are not ideal for mouth care in an unconscious client: Fowler’s position may increase the risk of aspiration, the supine position can lead to aspiration as well, and Trendelenburg position is not recommended due to potential adverse effects on blood circulation and increased intracranial pressure.

4. The four main concepts common to nursing that appear in each of the current conceptual models are:

• A. Person, nursing, environment, medicine
• B. Person, health, nursing, support systems
• C. Person, health, psychology, nursing
• D. Person, environment, health, nursing

Correct answer: D

Rationale: The four main concepts common to nursing that appear in each of the current conceptual models are person, environment, health, and nursing. These concepts form the foundational principles that guide nursing practice and theory.

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.
