Answer: (D)

Verified step by step guidance

1. Step 1: Begin by identifying the primary function of the organ systems listed in the problem. For example, the respiratory system is responsible for gas exchange, the endocrine system regulates hormones, and the digestive system processes food.
2. Step 2: Understand the role of the integumentary system. It includes the skin, hair, nails, and associated glands, and its primary functions are protection, temperature regulation, and sensory reception.
3. Step 3: Consider the scenario described in the problem: a nurse preparing a section of skin for an injection. This involves the skin, which is part of the integumentary system, as it serves as a protective barrier and the site of interaction.
4. Step 4: Eliminate the other options by reasoning that the respiratory, endocrine, and digestive systems are not directly involved in the preparation of skin for an injection.
5. Step 5: Conclude that the integumentary system is the correct answer because the skin is the organ being prepared for the injection, showcasing its protective and interactive role.
