1. Based on the principles of asepsis, the nurse should consider a sterile packet below waist level to be _____.

Correct answer: A

Rationale: In aseptic techniques, maintaining the sterility of items is crucial. Placing a sterile packet below waist level exposes it to potential contamination from non-sterile surfaces or objects. Therefore, the correct term to describe the sterile packet in this situation is 'contaminated.' 'Sterilized' (choice B) is incorrect as it implies the packet has undergone a sterilization process, which may not be the case if it is now considered contaminated. 'Clean' (choice C) is incorrect because although the packet was initially sterile, placing it below waist level compromises its cleanliness. 'Untouched' (choice D) is incorrect as the packet has been touched or exposed to non-sterile areas, leading to potential contamination.

2. What is the main component of air?

Correct answer: B

Rationale: Nitrogen is the main component of air, constituting approximately 78% of the Earth's atmosphere. Oxygen, carbon dioxide, and argon are also present in smaller amounts, but nitrogen is the most abundant gas in the air. Therefore, the correct answer is B. Choice A, oxygen, is essential for respiration but makes up only about 21% of the atmosphere. Choice C, carbon dioxide, is vital for photosynthesis but exists in trace amounts in the air. Choice D, argon, is a noble gas found in relatively small quantities in the atmosphere.

3. Which of the following is not part of the body’s secondary defense system?

Correct answer: D

Rationale: Cilia are not part of the body's secondary defense system. They are hair-like structures primarily involved in movement and transporting substances across cell surfaces, such as in the respiratory tract for debris and pathogen removal. However, cilia do not play a direct role in the immune response mechanisms characteristic of the body's secondary defense system. Macrophages, leukocytes, and T cells are immune cells that actively participate in the secondary defense system by targeting and eliminating pathogens.

4. Why doesn’t a raindrop accelerate as it approaches the ground?

Correct answer: B

Rationale: The correct answer is B. As a raindrop falls, it experiences air resistance which counteracts the gravitational force pulling it down. This balancing of forces prevents the raindrop from accelerating further as it approaches the ground. Choice A is incorrect because while gravity is pulling the raindrop down, air resistance opposes this force. Choice C is incorrect as the mass of the raindrop remains constant during its fall. Choice D is incorrect because objects in motion may decelerate due to various factors, but in this case, the focus is on why the raindrop doesn't accelerate.

5. What is the function of the gallbladder in the digestive system?

Correct answer: B

Rationale: The gallbladder's main function is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. Therefore, the correct answer is B, as the gallbladder acts as a reservoir for bile rather than producing it. Choices A, C, and D are incorrect because the gallbladder does not produce bile, detoxify harmful substances, or regulate blood sugar in the digestive system.
