A nurse is assessing a client who has a spinal cord injury at the level of T6. Which of the following findings should the nurse expect? (Select all that apply.)

Choice A reason:

This is a correct answer. A spinal cord injury at the level of T6 affects the sensory nerves that innervate the lower half of the body, resulting in loss of sensation below the waist.

Choice B reason:

This is a correct answer. A spinal cord injury at the level of T6 affects the motor nerves that innervate the lower half of the body, resulting in paralysis of the lower extremities.

Choice C reason:

This is a correct answer. A spinal cord injury at the level of T6 affects the autonomic nerves that innervate the bladder and bowel, resulting in impaired bladder and bowel control.

Choice D reason:

This is an incorrect answer. A spinal cord injury at the level of T6 does not affect the cranial nerves that innervate the pharynx and esophagus, which are responsible for swallowing.

Choice E reason:

This is a correct answer. A spinal cord injury at the level of T6 affects the autonomic nerves that innervate the sweat glands and thermoregulatory centers, resulting in decreased sweating and shivering.

Choice A reason:

This is a correct answer. Glia cells are supportive cells that provide insulation, protection, nutrition, and regulation for neurons. One type of glia cells, called oligodendrocytes, produce myelin that insulates nerve fibers and increases the speed of electrical impulses.

Choice B reason:

This is an incorrect answer. Glia cells do not transmit electrical impulses along nerve fibers. This is the function of neurons, which are the primary cells of the nervous system.

Choice C reason:

This is an incorrect answer. Glia cells do not secrete neurotransmitters that communicate with other cells. This is also the function of neurons, which release neurotransmitters at the synapses to transmit signals to other neurons, muscles, or glands.

Choice D reason:

This is an incorrect answer. Glia cells do not destroy pathogens and foreign substances in the nervous system. This is the function of microglia, which are a type of immune cells that reside in the nervous system and act as macrophages.
