The shingles virus can cause

Correct Answer: C

Rationale: The correct answer is C: Chickenpox in a person who has never had it. The shingles virus, also known as herpes zoster, is caused by the reactivation of the varicella-zoster virus, which initially causes chickenpox. When the virus reactivates, it can lead to a painful rash and blisters, known as shingles, particularly in individuals who have had chickenpox before. Scabs due to tiny mites (A), abrasion due to friction (B), and severe fungal infections (D) are unrelated to the shingles virus and do not align with its characteristic symptoms.

Correct Answer: A

Rationale: The correct answer is A: Brain. The brain is a crucial component of the central nervous system, responsible for processing information, controlling bodily functions, and regulating emotions. It is the main organ that coordinates all activities in the body. Nerves (choice B) are part of the peripheral nervous system, not the central nervous system. Eyes and ears (choice C) are sensory organs that transmit information to the brain but are not part of the central nervous system. The autonomic nervous system (choice D) is a division of the peripheral nervous system that controls involuntary bodily functions, such as heart rate and digestion, and is not part of the central nervous system.

Correct Answer: C

Rationale: The correct answer is C: Iodine. Iodine is essential for thyroid hormone production, which regulates metabolism. Common table salt is often iodized to prevent iodine deficiency. Potassium (A) is important for heart and muscle function, but not specifically for thyroid function. Magnesium (B) plays various roles in the body but is not directly related to thyroid function. Copper (D) is involved in enzyme function but is not a primary mineral for thyroid gland function.

Correct Answer: B

Rationale: The correct answer is B: Assistive device. Assistive devices are designed to help disabled individuals perform daily activities. They can include wheelchairs, hearing aids, and adaptive tools. Orthotic devices (A) are used for support or alignment, not specifically for daily activities. Restorative devices (C) aim to improve function, not solely assist in daily living. Range of motion devices (D) focus on movement limitations, not daily tasks. Therefore, B is the best choice for devices aiding in daily living activities.

Correct Answer: C

Rationale: The correct answer is C: Bereavement. Bereavement refers to the period following a loss in which mourning occurs. It is a time of grieving and coming to terms with the loss. Breakthrough is unrelated, burnout refers to exhaustion, and blackout denotes a loss of consciousness. Bereavement specifically addresses the process of mourning and coping with loss.
