The ________ cerebral hemisphere of the brain controls the motor activity on the right side of the body.

Correct Answer: D

Rationale: The correct answer is D: Left. The left cerebral hemisphere controls motor activity on the right side of the body due to the brain's contralateral organization. This means that the left hemisphere is responsible for controlling the opposite side of the body. The other choices are incorrect because the right hemisphere does not control the right side of the body (A), the middle hemisphere is not a recognized brain division (B), and the spinal cord is not directly involved in motor control originating from the brain (C).

Correct Answer: D

Rationale: The correct answer is D: Hyperextended. When a joint is extended beyond its normal range of motion, it is considered hyperextended. This means that the joint is moved past its usual limit in the direction opposite to flexion. Flexion (choice A) is the bending of a joint, not extending it. Opposed (choice B) refers to two things being against each other and is not related to joint motion. Pronation (choice C) is the inward rotation of the forearm, not joint extension. Hyperextension is the only choice that accurately describes the scenario of a joint being extended beyond its normal motion limit.

Correct Answer: C

Rationale: The correct answer is C: Autopsy. An autopsy is a thorough examination of a body by a pathologist to determine the cause of death. Atrophy (A) refers to the wasting away of body tissues, not an examination. Anatomy (B) is the study of the structure of organisms, not specifically related to determining cause of death. Avulsion (D) is the tearing away of a body part, not related to postmortem examinations. Therefore, C is the correct answer as it directly relates to the process of determining cause of death through a detailed examination.

Correct Answer: C

Rationale: The correct answer is C: Hepatitis B. This is because Hepatitis B is an occupational hazard for healthcare workers, requiring employers to provide the vaccine to employees free of charge. Measles, Ebola, and Malaria are not typically considered occupational hazards in most work settings, so providing vaccines for these diseases is not a legal requirement for employers. Hepatitis B vaccination helps protect employees from potential exposure in the workplace, making it a necessary and mandated vaccine for certain occupations.
