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. Which of the following patients is at greatest risk for developing pressure ulcers?

• A. An alert chronic arthritic patient treated with steroids and aspirin
• B. An 88-year-old incontinent patient with gastric cancer who is confined to bed at home
• C. An apathetic 63-year-old COPD patient receiving nasal oxygen via cannula
• D. A confused 78-year-old patient with congestive heart failure (CHF) who requires assistance to get out of bed

Correct answer: B

Rationale: The correct answer is B. An elderly patient who is incontinent, bedridden, and suffering from a serious illness like gastric cancer is at the highest risk for developing pressure ulcers. Being bedridden and incontinent increases the pressure on certain areas of the body, leading to tissue damage and the development of pressure ulcers. Additionally, the patient's age and underlying health condition further contribute to their risk. It is crucial to identify and address such risk factors promptly to prevent the occurrence of pressure ulcers in vulnerable patients.

3. Which of the following is included in Orem’s theory?

• A. Maintenance of a sufficient intake of air
• B. Self-perception
• C. Love and belonging
• D. Physiological needs

Correct answer: A

Rationale: Orem's theory, also known as the Self-Care Deficit Nursing Theory, focuses on individuals' ability to perform self-care to maintain health and well-being. One specific component of this theory is the maintenance of a sufficient intake of air, which is crucial for sustaining life and overall health. Option A is the correct choice as it directly relates to meeting physiological needs, such as the intake of air, to support optimal functioning and health. Choices B, C, and D are incorrect as they do not specifically align with Orem's emphasis on self-care and meeting physiological requirements.

4. When preparing to administer an IM injection that is irritating to the subcutaneous tissue, what is the best action to prevent tracking of the medication?

• A. Use a small gauge needle
• B. Apply ice on the injection site
• C. Administer at a 45° angle
• D. Use the Z-track technique

Correct answer: D

Rationale: The Z-track technique is the best action to prevent tracking of the medication when administering an IM injection that is irritating to the subcutaneous tissue. This technique involves pulling the skin to the side before administering the injection and then releasing the skin after the injection. By doing so, a zig-zag pathway is created, preventing the medication from leaking into the subcutaneous tissue and reducing irritation. Options A, B, and C are incorrect. Using a small gauge needle may not prevent tracking of the medication. Applying ice on the injection site or administering at a 45° angle does not specifically address preventing tracking of the medication in cases where the injection is irritating to the subcutaneous tissue.

5. After routine patient contact, how long should hand washing last at least?

• A. 30 seconds
• B. 1 minute
• C. 2 minutes
• D. 3 minutes

Correct answer: A

Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.
