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 liters are equal to 1800 ml?

• A. 1.8
• B. 18000
• C. 180
• D. 2800

Correct answer: A

Rationale: To convert milliliters (ml) to liters, divide by 1000 since 1 liter is equal to 1000 ml. Therefore, 1800 ml is equal to 1800/1000 = 1.8 liters. Choice A (1.8) is correct. Choice B (18000) is incorrect as it equates to 18000 liters, not 1.8 liters. Choice C (180) is incorrect as it represents 180 liters, not 1.8 liters. Choice D (2800) is incorrect as it does not reflect the conversion of 1800 ml to liters.

3. When teaching about electrical fire prevention at a community health fair, which of the following information should be included?

• A. Use three-pronged grounded plugs.
• B. Cover extension cords with a rug.
• C. Check for tingling sensations around the cord to ensure electricity is working.
• D. Remove the plug from the socket by pulling the plug, not the cord.

Correct answer: A

Rationale: The correct answer is to use three-pronged grounded plugs because they are safer and reduce the risk of electrical fires. Option B is incorrect as covering extension cords with a rug can pose a fire hazard. Option C is incorrect; tingling sensations around a cord indicate an electrical issue, not proper functioning. Option D is unsafe; plugs should be removed from the socket by pulling the plug, not the cord, to prevent damage and reduce the risk of electrical hazards.

4. What is the meaning of PRN?

• A. When advice
• B. Immediately
• C. When necessary
• D. Now

Correct answer: C

Rationale: The correct meaning of PRN is 'when necessary.' The abbreviation 'PRN' comes from the Latin term 'pro re nata,' which is commonly used in medical contexts to indicate that a medication should be taken as needed, not at scheduled intervals. Choice A ('When advice') is incorrect as PRN does not refer to seeking advice. Choice B ('Immediately') is incorrect as PRN does not imply urgency. Choice D ('Now') is incorrect as PRN does not mean 'immediate' but rather 'as needed.' Therefore, the correct answer is C, 'When necessary.'

5. For abdominal inspection, in which of the following positions should a patient be placed?

• A. Prone
• B. Trendelenburg
• C. Supine
• D. Side-lying

Correct answer: C

Rationale: The supine position is ideal for abdominal inspection as it allows the healthcare provider to easily access and examine the abdomen. In the supine position, the patient lies flat on their back with arms at their sides, providing a clear view and access to the abdominal area for inspection.
