The nurse is assessing a client’s joint for range of movement after falling in the shower. The nurse asks the client to move the right arm away from the center of the body. The nurse correctly documents the joint movement as?
Flexion
Extension
Abduction
Adduction

Choice A rationale: Flexion involves decreasing the angle between two body parts, typically bending a joint.
Choice B rationale: Extension involves increasing the angle between two body parts, typically straightening a joint.
Choice C rationale: Moving the right arm away from the center of the body is an example of abduction, which is the movement of a body part away from the midline.

Correct Answer is D
Explanation
Choice A rationale: The normal liver span is 6-12 cm above the right coastal margin hence this finding is normal.
Choice B rationale: This finding is normal and does not indicate hepatomegaly.
Choice C rationale: Additional health history questions regarding alcohol intake may not be relevant in this case since the patient has a normal liver span.
Choice D rationale: The normal liver span in the midclavicular line is 6 to 12 cm, so an area of dullness of 11 cm above the right costal margin is within the normal range.
Correct Answer is C
Explanation
Choice A rationale: The central nervous system consists of the brain and spinal cord, not "electrical impulse stimulators."
Choice B rationale: The hypothalamus is a part of the brain, but the central nervous system encompasses both the brain and the spinal cord.
Choice C rationale: The central nervous system (CNS) is made up of the brain and spinal cord. The CNS processes and interprets sensory information and sends motor commands to effectors.
Choice D rationale: The peripheral nervous system and autonomic nervous system are distinct from the central nervous system and are not part of the CNS.
