Rheumatoid arthritis is an autoimmune illness. With an autoimmune illness, the body's ______ system attacks normal tissue.

Correct Answer: D

Rationale: The correct answer is D: Immune. In autoimmune illnesses like rheumatoid arthritis, the body's immune system mistakenly attacks its own tissues. The immune system is responsible for recognizing and fighting off foreign invaders, but in autoimmune diseases, it malfunctions and targets healthy cells. The endocrine system (choice A) regulates hormones, the lymphatic system (choice B) helps with immune response, and the circulatory system (choice C) transports nutrients and oxygen but is not directly involved in autoimmune attacks. Thus, the immune system (choice D) is the correct choice in this context.

Correct Answer: A

Rationale: The correct answer is A: Intolerance to cold. Hypothyroidism is characterized by a slowed metabolism, leading to feeling cold. Choice B, bulging eyes, is a symptom of hyperthyroidism. Choice C, rapid heartbeat, is a symptom of hyperthyroidism as well. Choice D, normal menstrual periods, is not specific to hypothyroidism. Therefore, the correct choice is A.

Correct Answer: C

Rationale: Flexion is the correct answer because it refers to the bending of a body part, decreasing the angle between two body parts.

Therefore, flexion is the most appropriate term for bending a body part.

Rationale: The correct answer is C because subacute care is designed for individuals who require more than basic care but do not need intensive acute care. It provides a higher level of medical supervision and skilled nursing care than long-term care. Choice A is incorrect because subacute care is typically provided in a healthcare facility, not a home setting. Choice B is incorrect as it refers to a different type of care for individuals with developmental disabilities. Choice D is incorrect because subacute care is not specifically focused on elderly patients who are dying but rather on those needing specialized care for a limited period.
