An adult client with a closed head injury was admitted to the intensive care unit (ICU) one hour ago following a motor vehicle collision. The client's telemetry displays normal sinus rhythm. After placing an intraventricular cannula for intracranial pressure monitoring, the healthcare provider (HCP) prescribes protocols for IV infusions of mannitol and dopamine. Which nursing intervention has the highest priority?
Observe vital signs sequences as a way of assessing for Cushing's triad.
Evaluate hourly urinary output.
Monitor arterial blood pressure.
Assess intracranial pressure following intracranial transducer placement.
The Correct Answer is D
A. Observe vital signs sequences as a way of assessing for Cushing's triad. Cushing’s triad (hypertension with widened pulse pressure, bradycardia, and irregular respirations) is a late sign of increased intracranial pressure (ICP). While monitoring for it is important, early recognition and direct ICP monitoring are more effective in preventing deterioration.
B. Evaluate hourly urinary output. Mannitol is an osmotic diuretic that can cause significant diuresis, requiring close monitoring of urine output to prevent dehydration and electrolyte imbalances. However, assessing ICP is the priority because increased ICP can cause brain herniation, which is life-threatening.
C. Monitor arterial blood pressure. Dopamine is a vasopressor used to maintain cerebral perfusion pressure (CPP), which is crucial in head injury management. While blood pressure monitoring is essential, directly assessing ICP ensures that treatment is effective in preventing secondary brain injury.
D. Assess intracranial pressure following intracranial transducer placement. The highest priority is monitoring ICP immediately after placement to detect dangerous elevations that could lead to herniation. The intraventricular catheter provides real-time pressure readings, guiding interventions like mannitol administration and blood pressure control to optimize cerebral perfusion and prevent worsening neurological damage.

Correct Answer is A
Explanation
A. Provide a bedside table for the client to lean across. Clients with acute pancreatitis often experience severe epigastric pain that radiates to the back. Leaning forward helps reduce pressure on the inflamed pancreas and relieves pain by minimizing peritoneal irritation. Providing a bedside table allows the client to rest in a comfortable, supported position, improving pain management without additional interventions.
B. Place bed in the reverse Trendelenburg position. Reverse Trendelenburg elevates the head and lowers the feet, which does not specifically relieve pain associated with pancreatitis. The client instinctively leans forward for relief, and adjusting the bed position would not provide the same benefit. This intervention does not directly address the underlying cause of discomfort.
C. Encourage bed rest until analgesic takes effect. Although pain control is essential, keeping the client in a supine or bedrest position can increase abdominal pressure and worsen discomfort. Allowing the client to assume a comfortable position enhances the effectiveness of analgesics and prevents unnecessary distress. Pain relief strategies should focus on both pharmacologic and positioning interventions.
D. Raise the head of the bed to a 90-degree angle. Elevating the head of the bed can improve breathing and reduce reflux, but it does not provide the same pressure relief as leaning forward. Sitting upright without forward support does not effectively relieve peritoneal irritation from pancreatic inflammation. Providing a bedside table supports proper positioning and enhances comfort.
Correct Answer is A
Explanation
A. Administer a PRN bolus normal saline. The client is exhibiting signs of hypovolemic shock, including tachycardia (HR 110 bpm), tachypnea (RR 24), and hypotension (BP 80/50 mmHg) following massive gastrointestinal bleeding and multiple blood transfusions. Immediate fluid resuscitation with a normal saline bolus is the priority to restore intravascular volume, maintain perfusion, and prevent further deterioration.
B. Obtain a blood specimen for hematocrit. While monitoring hematocrit is important to assess ongoing blood loss, it does not take priority over treating the client’s current hypovolemia. A delay in resuscitation could worsen hypotension, decrease organ perfusion, and lead to shock.
C. Measure strict hourly urinary output. Monitoring urine output is important in assessing renal perfusion and fluid balance, but the client’s immediate need is volume replacement. If fluid resuscitation is delayed, renal perfusion could worsen, leading to acute kidney injury.
D. Switch oxygen delivery to a face mask. The client’s oxygen saturation is 94% on 4 L/min nasal cannula, indicating adequate oxygenation at this time. Increasing oxygen delivery is not immediately necessary compared to fluid resuscitation. However, if the client’s condition worsens, oxygen therapy adjustments may be needed.
