Grace [21]

You are caring for a patient who has suffered a spinal cord injury. You are concerned about the patient's elimination status. As the nurse, your primary concern is to establish a bowel and bladder routine for the patient.

It is a priority to ensure appropriate elimination for the spinal cord injury patient. It is OK to consult with family members to ascertain culinary preferences, although this is not the major focus. Speaking with the patient to learn about previous elimination habits is not appropriate because spinal cord damage alters elimination behaviours. Setting up a sleep routine does not apply to elimination.

What is the spinal cord?

  • The spinal cord is a long, tube-like tissue band.
  • It is the link between your brain and your lower back.
  • The spinal cord transmits nerve messages from the brain to the body and vice versa.
  • These nerve messages assist you in feeling feelings and moving your body.
  • Any spinal cord damage might impair your movement or function.
