One function of the integumentary system is to

Correct Answer: C

Rationale: The correct answer is C: Protect internal organs from injury. The integumentary system consists of the skin, hair, nails, and glands that protect the body from external factors like pathogens, UV rays, and physical injuries. The skin acts as a barrier, preventing harmful substances from entering the body and also helps regulate body temperature. Choices A, B, and D are incorrect because excreting waste through urine is the function of the urinary system, the production of vitamin C is primarily done by the liver and kidneys, and increasing body temperature is regulated by the thermoregulatory system, not the integumentary system.

Correct Answer: B

Rationale: The correct answer is B: Adduction. Adduction refers to the movement of a body part towards the midline of the body. This is the correct term for moving a body part towards the body. In contrast, A: Addition is not a term used in anatomy for this type of movement. C: Agitation is unrelated to the movement of body parts. D: Abduction is the opposite movement, where a body part moves away from the midline of the body. Therefore, B is the correct answer as it specifically describes the action of moving a body part towards the body's midline.

Correct Answer: A

Rationale: The correct answer is A because applying products between the toes can lead to moisture accumulation, which increases the risk of fungal infections in diabetic individuals. It is crucial to maintain dryness in the foot area to prevent infections. Turning socks over at the tops (choice B) does not directly relate to foot care for diabetic residents. Using all-nylon socks (choice C) may not be suitable as they can trap moisture. Cutting toenails carefully (choice D) is important but does not address the specific guideline for foot care in diabetic individuals.

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 with Human Herpesvirus 8 and weakened immune system. Kaposi's sarcoma presents as skin lesions or tumors in various organs. Choices A, B, and C are incorrect as Pneumocystis pneumonia is a common opportunistic infection in AIDS, prostate cancer and liver cancer are not specifically linked to AIDS.

Correct Answer: C

Rationale: The correct answer is C because clots in the drainage tubing can obstruct the flow of fluid, leading to complications like pneumothorax. It is crucial to report this issue promptly to prevent respiratory distress. A: Drainage system level does not directly affect the function of the chest tube. B: Resident's nap frequency is unrelated to chest tube care. D: Upright drainage containers are appropriate for gravity drainage.
