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 sharps and pose a risk of injury and infection if not disposed of properly. Special handling is required to prevent accidental cuts or punctures. Heavy-duty gloves (B) are not disposable equipment. Paper gown (C) and cup (D) are not sharps and do not pose the same risks when discarded. Sharps require specific disposal protocols to ensure safety.

Correct Answer: C

Rationale: The correct answer is C: Glucose. Glucose is a natural sugar that serves as the primary source of energy for the body's cells. It is derived from the foods we eat and is essential for various physiological 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 directly relates to being a natural sugar used by the body for energy.

Correct Answer: D

Rationale: The correct answer is D: Midstream. A clean-catch specimen, also known as midstream urine, is collected during the middle of urination to avoid contamination from the initial and final urine flow. This method minimizes external bacteria and cells from the urethra. Choice A, contaminated, is incorrect as the goal of a clean-catch specimen is to reduce contamination. Choice B, cleansing, is unrelated to the specific urine collection process. Choice C, stop and start, does not accurately describe the method used for collecting a clean-catch specimen.

Correct Answer: D

Rationale: The correct answer is D, Third-degree burn. This type of burn affects the epidermis, dermis, and underlying tissue, causing extensive damage. The epidermis and dermis are completely destroyed, leading to loss of sensation and potential scarring. First-degree burns (B) only affect the epidermis, while second-degree burns (A) involve the epidermis and part of the dermis. Partial-thickness burns (C) are a general term that can refer to both first and second-degree burns, but do not specifically indicate involvement of underlying tissue.

Correct Answer: C

Rationale: The correct answer is C: Increased lung capacity. Deep-breathing exercises involve taking slow, deep breaths, which can strengthen the respiratory muscles and improve the efficiency of oxygen exchange in the lungs. This leads to an increase in lung capacity over time. Choice A is incorrect as deep-breathing exercises actually help in clearing mucus from the respiratory system. Choice B is incorrect as deep-breathing exercises do not decrease salivary production. Choice D is incorrect as deep-breathing exercises actually help in increasing oxygen levels in the body by improving oxygen intake and utilization.
