A client in the gynecology clinic asks the nurse, ‘’What are the risk factors for developing cervical cancer?’’ Which statement by the nurse is the best response?

A) 3% Normal Saline:
Elevated ICP can lead to a life-threatening condition known as cerebral herniation, and it often triggers the Cushing’s triad—widened pulse pressure, bradycardia, and irregular respirations, all of which the nurse has noted. Hypertonic saline (such as 3% Normal Saline) is commonly used to manage increased ICP because it creates an osmotic gradient that draws fluid out of the brain tissue, reducing cerebral edema and lowering ICP. The goal is to reduce swelling and prevent further brain damage.

B) Nitroprusside:
Nitroprusside is a potent vasodilator that is used to treat hypertension and reduce afterload in conditions like heart failure or aortic dissection. However, in this case, nitroprusside is contraindicated because it could cause a drop in systemic blood pressure, which would worsen cerebral perfusion in a patient with elevated ICP.

C) Norepinephrine:
Norepinephrine is a vasopressor used to treat hypotension by increasing systemic vascular resistance and blood pressure. Although norepinephrine may be used to support blood pressure in critically ill patients, in this context of elevated ICP, the priority is to reduce ICP, not to increase blood pressure further. Increasing the systemic vascular resistance with norepinephrine could exacerbate ICP by increasing the volume of blood in the cranium

D) Furosemide:
Furosemide is a loop diuretic that can reduce fluid volume and help treat conditions like edema or heart failure. While furosemide can reduce overall fluid volume, it is not typically used to manage elevated ICP in this context. Diuretics like furosemide may have a role in managing cerebral edema, but they are not as effective as hypertonic saline in rapidly reducing ICP.

A) Respiratory compromise
A spinal cord injury (SCI) at the level of C-3 (cervical spine) results in the loss of function of the diaphragm, which is innervated by the phrenic nerve originating from C-3 to C-5. As a result, the patient is at high risk for respiratory compromise and may require mechanical ventilation. Respiratory failure is a leading cause of death and complications in individuals with high cervical spinal cord injuries, particularly when the injury is at or above C-4.

B) Hypertension
Although spinal cord injuries can cause autonomic dysreflexia (a condition where the body’s autonomic nervous system overreacts to stimuli, leading to dangerously high blood pressure), this condition is more common in individuals with injuries above T6. At C-3, respiratory issues are the primary concern, and hypertension is not the leading cause of complications.

C) Septic shock
Septic shock can occur after any significant injury, especially if the individual develops infections (e.g., from urinary retention, pressure ulcers, or pneumonia). However, septic shock is not the main cause of complications or death related to a C-3 spinal cord injury.

D) Bradycardia
Bradycardia (a slow heart rate) can indeed be a concern in patients with SCI, especially those with injuries at or above the T1 level. However, at the level of C-3, the main cause of complications is respiratory failure, not bradycardia. While bradycardia can occur due to disruption of sympathetic nervous system control, respiratory compromise is the most critical immediate concern.
