A nurse is caring for a client who had a right sided stroke and is exhibiting homonymous hemianopsia when eating. Which of the following actions should the nurse take?

Choice A reason: Hyperthermia. This answer is incorrect because hyperthermia is not a complication of a cervical spinal cord injury, but rather a condition that can worsen the injury. Hyperthermia can increase the metabolic demand and oxygen consumption of the injured spinal cord, leading to more damage and inflammation.

Choice B reason: Absence of bowel sounds. This answer is correct because absence of bowel sounds is a complication of a cervical spinal cord injury, which can affect the autonomic nervous system and impair the function of the gastrointestinal system. A cervical spinal cord injury can cause spinal shock, which leads to decreased peristalsis and paralytic ileus.

Choice C reason: Polyuria. This answer is incorrect because polyuria is not a complication of a cervical spinal cord injury, but rather a condition that can occur after the resolution of spinal shock. Polyuria can result from the loss of sympathetic control over the renal system, leading to increased urine output and decreased antidiuretic hormone secretion.

Choice D reason: Weakened gag reflex. This answer is correct because weakened gag reflex is a complication of a cervical spinal cord injury, which can affect the autonomic nervous system and impair the function of the respiratory system. A cervical spinal cord injury can cause damage to the cranial nerves that control the gag reflex, leading to difficulty swallowing, aspiration, and pneumonia.

Choice E reason: Hypotension. This answer is correct because hypotension is a complication of a cervical spinal cord injury, which can affect the autonomic nervous system and impair the function of the cardiovascular system. A cervical spinal cord injury can cause neurogenic shock, which leads to decreased sympathetic tone, vasodilation, and reduced cardiac output.

Choice A reason: The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygen saturation of the arterial blood. Central cyanosis occurs when the arterial blood has a low oxygen saturation due to a cardiopulmonary problem. The oral mucosa is less affected by peripheral factors such as temperature, vasoconstriction, or skin pigmentation.

Choice B reason: The conjunctivae are not a reliable indicator of central cyanosis because they can be affected by other conditions such as anemia, jaundice, or eye infections. The conjunctivae are the thin membranes that cover the white part of the eye and the inner surface of the eyelids.

Choice C reason: The ear lobes are not a reliable indicator of central cyanosis because they can be affected by peripheral factors such as temperature, vasoconstriction, or skin pigmentation. The ear lobes are the fleshy lower part of the external ear.

Choice D reason: The soles of the feet are not a reliable indicator of central cyanosis because they can be affected by peripheral factors such as temperature, vasoconstriction, or skin pigmentation. The soles of the feet are the bottom part of the feet.
