A nurse is providing care for a postoperative client. Which of the following manifestations should the nurse identify as indicating the development of postoperative shock?

A. Administer acetaminophen by mouth for pain control: While pain management is important, it is not the priority intervention in this situation. Administering acetaminophen for pain control can be done after the client's condition has been assessed and any potential serious injuries, such as head trauma, have been addressed.

B. Perform a thorough health history: Obtaining a health history is essential for understanding the client's baseline health status and any pre-existing conditions that may affect their current condition. However, in the acute phase following a traumatic fall, the priority is to assess and manage any potential life-threatening injuries.

C. Prepare for a STAT non-contrast CT scan: This is the correct answer. In cases of traumatic falls, particularly when there is concern for head injury or intracranial bleeding, obtaining a non-contrast CT scan of the head is a priority. This imaging study helps identify any intracranial injuries such as hemorrhage or skull fractures, allowing for prompt intervention if necessary.

D. Insert an indwelling urinary catheter to monitor urine output: Monitoring urine output is important for assessing renal function, but it is not the priority intervention in the immediate aftermath of a traumatic fall. The focus initially should be on assessing and managing potential life-threatening injuries, particularly those related to head trauma.

A. Respiratory rate of 12/min: A respiratory rate of 12/min is within the normal adult range (12-20 breaths per minute). In the context of increased intracranial pressure (ICP), respiratory rate changes might be noted as part of the Cushing's reflex (which is characterized by bradycardia, hypertension, and abnormal respiratory patterns like Cheyne-Stokes or ataxic breathing), but a rate of 12/min on its own is not indicative of a worsening condition. However, if the patient begins to show signs of irregular or abnormal breathing patterns, this would raise concern.

B. Blood pressure of 108/74 mm Hg: This blood pressure is also within the normal range and does not suggest a worsening of intracranial pressure. In fact, ICP can lead to a rise in blood pressure (due to the body's compensatory mechanisms, known as Cushing's triad), along with bradycardia and abnormal respirations. Thus, a stable blood pressure like 108/74 mm Hg is not concerning in this context.

C. Changes to pupil size and shape: Changes in pupil size, shape, or reactivity are significant indicators of worsening intracranial pressure. Unequal pupils (anisocoria), sluggish or absent response to light, and fixed dilated pupils are signs of brainstem compression or damage, which often occur as ICP increases. This could indicate herniation or severe brain injury, which are worsening conditions.

D. Swelling of the optic nerve: Swelling of the optic nerve, or papilledema, is another important sign of increased intracranial pressure. It occurs due to increased pressure within the skull, which causes congestion and swelling of the optic disc. This finding can be seen on fundoscopy and indicates a worsening condition, as it suggests elevated pressure affecting the brain.

E. Decreasing Glasgow Coma scores: A decreasing Glasgow Coma Scale (GCS) score is a critical indicator of worsening neurologic function in a patient with increased ICP. The GCS is used to assess a patient's level of consciousness, and a decreasing score suggests that the brain's function is deteriorating. This can be caused by worsening edema, brain herniation, or other severe neurological impairments associated with elevated ICP.
