Which of the following is a type of disposable equipment that requires special handling when discarding?

Correct Answer: A

Rationale: The correct answer is A: Razor. Razors are considered disposable sharps, which pose a potential risk of injury and infection if not handled properly. Special handling is required for disposal to prevent harm to waste handlers. Heavy-duty gloves, paper gowns, and cups are generally considered regular disposable items that do not pose the same level of risk and do not require special handling like sharps. Therefore, razors stand out as the correct choice for requiring special handling when discarding.

Correct Answer: C

Rationale: The correct answer is C: Glucose. Glucose is a natural sugar that is a primary source of energy for the body's cells. It is produced during the process of photosynthesis in plants and is essential for various cellular functions. Sodium (A) is an electrolyte, not a sugar. Cholesterol (B) is a type of lipid, not a sugar. Gluten (D) is a protein found in wheat and other grains, not a sugar used for energy. Therefore, the correct choice is glucose as it aligns with the role of sugars in providing energy for the body.

Correct Answer: D

Rationale: The correct answer is D: Midstream. A clean-catch specimen, also known as a midstream specimen, is collected after the initial stream of urine to avoid contamination from the urethra or external genitalia. This method helps ensure a more accurate sample for testing. A: Contaminated - Incorrect. This term implies impurity, which is the opposite of what a clean-catch specimen aims to achieve. B: Cleansing - Incorrect. While cleanliness is important in specimen collection, this term does not specifically refer to the methodology of a clean-catch specimen. C: Stop and start - Incorrect. This term does not accurately describe the process of collecting a clean-catch specimen, which involves a continuous flow after the initial voiding.

Correct Answer: D

Rationale: The correct answer is D: Third-degree burn. A third-degree burn affects the epidermis, dermis, and underlying tissue, resulting in damage to all layers of the skin. This type of burn is the most severe, causing significant tissue destruction and requiring medical attention. A: Second-degree burn only affects the epidermis and dermis, not the underlying tissue. B: First-degree burn only affects the outer layer of the skin (epidermis). C: Partial-thickness burn is a general term that can refer to both first- and second-degree burns, but it does not specifically indicate damage to the underlying tissue like a third-degree burn does.

Correct Answer: C

Rationale: The correct answer is C: Increased lung capacity. Deep-breathing exercises involve inhaling deeply, which helps to expand the lungs and improve their capacity. This allows for more efficient oxygen exchange and can improve overall respiratory function. Increased mucus in the respiratory system (A) is not a benefit of deep-breathing exercises and can actually be a sign of respiratory issues. Decreased salivary production (B) is unrelated to deep-breathing exercises. Decreased oxygen levels (D) would be counterproductive to the goal of deep-breathing exercises, which aim to improve oxygen intake.
