A nurse is caring for a client who is at risk for shock. Which of the following findings is the earliest indicator that this complication is developing?

Choice A Reason: This is incorrect because the results are not within the expected reference range. The client's BUN, creatinine, and hematocrit are elevated, indicating dehydration or reduced renal perfusion.

Choice B Reason: This is correct because evaluating urine for amount and for specific gravity can help assess the client's hydration status and renal function. These actions can help assess the client's hydration status and renal function, which may be affected by nausea and vomiting. The client's BUN, creatinine, and hematocrit are elevated, indicating dehydration or reduced renal perfusion. The normal ranges for BUN are 7 to 20 mg/dL, for creatinine are

0.6 to 1.2 mg/dL, and for hematocrit are 38% to 50% for males. The nurse should monitor the urine output and specific gravity, which reflect the concentration and volume of urine. The normal range for urine output is 30 to 60 mL/hour, and for specific gravity is 1.005 to 1.030.

Choice C Reason: This is incorrect because collecting a urine specimen for culture and sensitivity is not indicated for this client. This action is used to diagnose urinary tract infections, which are not suggested by the client's symptoms or results.

Choice D Reason: This is incorrect because decreasing the IV fluid infusion rate and limiting oral fluid intake can worsen the client's dehydration and renal perfusion. The nurse should maintain adequate fluid intake and balance to prevent further complications.

Choice A: A cervical spinal cord injury can impair the function of cranial nerves, leading to a weakened gag reflex and an increased risk of aspiration.

Choice B:Patients with spinal cord injuries are more likely to experience poikilothermia (difficulty regulating body temperature), but this often results in hypothermia, not hyperthermia, due to the loss of autonomic temperature control.

Choice C:Spinal shock, which often follows a spinal cord injury, can cause decreased or absent bowel sounds due to a temporary loss of autonomic function and decreased peristalsis.

Choice D:Depending on the level and severity of the injury, paralysis can occur, affecting motor function below the injury site. A cervical spinal cord injury may lead to quadriplegia (tetraplegia).

Choice E:Clients with spinal cord injuries are more likely to experience urinary retention, rather than polyuria, due to loss of bladder control and autonomic dysfunction. A foley catheter may be needed initially, followed by intermittent catheterization.

Choice F:Neurogenic shock, a potential complication of cervical spinal cord injuries, can cause hypotension due to the loss of sympathetic nervous system control over blood vessel tone, leading to vasodilation and bradycardia.
