One function of the integumentary system is to

Correct Answer: C

Rationale: The correct answer is C because the integumentary system, which includes the skin, hair, and nails, acts as a protective barrier for internal organs from physical injury, pathogens, and harmful UV radiation. The skin's multiple layers provide a tough, waterproof covering that shields organs underneath. Option A is incorrect because waste excretion is primarily carried out by the urinary system. Option B is incorrect as the production of vitamin C occurs in the liver and some other body tissues, not the integumentary system. Option D is incorrect as the integumentary system helps regulate body temperature through processes like sweating and shivering, rather than directly increasing body temperature.

Correct Answer: B

Rationale: The correct answer is B: Adduction. Adduction refers to the movement of a body part toward the body's midline. This movement reduces the angle between the body part and the midline. It is the opposite of abduction, which is the movement away from the body's midline. Choice A (Addition) is not a term used in anatomy for describing body movements. Choice C (Agitation) is a term unrelated to body movements. Choice D (Abduction) is the opposite movement of what is described in the question. Therefore, the correct choice is B (Adduction) as it aligns with the specific movement described in the question.

Correct Answer: A

Rationale: The correct answer is A because applying products between the toes can lead to moisture buildup, increasing the risk of fungal infections in diabetic patients. This guideline helps prevent complications like athlete's foot. Turning socks over at the tops (B) and using all-nylon socks (C) are not specific to foot care for diabetic patients. Cutting toenails carefully (D) is important but not directly related to diabetic foot care.

Correct Answer: D

Rationale: The correct answer is D: Kaposi's sarcoma. This type of cancer is commonly associated with AIDS due to its link to the human herpesvirus 8 (HHV-8), which tends to affect individuals with weakened immune systems. Kaposi's sarcoma presents as skin lesions and can also affect internal organs. Pneumocystis pneumonia (A) is an opportunistic infection common in AIDS patients, not a cancer. Prostate cancer (B) and liver cancer (C) are not specifically associated with AIDS.

Correct Answer: C

Rationale: The correct answer is C because clots in the drainage tubing can obstruct fluid drainage, leading to potential complications such as pneumothorax or hemothorax. Clots need to be reported as they can impede the effectiveness of the chest tube. Choices A, B, and D are incorrect because they do not directly relate to a critical issue with chest tubes like clots do. A - The drainage system being below chest level can affect drainage but is not as critical as clots. B - The resident's nap schedule is not relevant to chest tube care. D - The orientation of drainage containers being upright does not pose a direct problem unless it impacts drainage flow.
