## 문제

A 7-year-old child with a newly diagnosed brainstem glioma is experiencing increased intracranial pressure (ICP). The child exhibits decerebrate posturing, irregular respirations, and a widening pulse pressure. Which nursing intervention should be the immediate priority?

The nurse is caring for a pediatric patient with brainstem glioma showing signs of increased intracranial pressure.

## 보기

1. Administer prescribed mannitol intravenously
2. Position the child in Trendelenburg position to improve cerebral perfusion
3. Encourage deep breathing exercises to improve oxygenation
4. Elevate the head of the bed 30 degrees and maintain neutral head alignment **✔ 정답**

**정답: 4**

## 해설

Elevating the head of the bed 30 degrees with neutral head alignment is the immediate priority intervention for managing increased ICP in pediatric patients with brain tumors.

This question assesses critical thinking about immediate nursing interventions for increased intracranial pressure in a pediatric patient with a brainstem glioma. The presented clinical picture—decerebrate posturing, irregular breathing, and widened pulse pressure—indicates Cushing's triad, signifying severely elevated intracranial pressure requiring immediate intervention.

Elevating the head of the bed to 30 degrees and maintaining the head in a neutral position is the most immediate and appropriate nursing intervention. This uses gravity to promote venous drainage from the brain, reducing intracranial volume and pressure. This positioning intervention can be implemented immediately without waiting for a physician's order and carries minimal risk of complications. Neutral head alignment prevents compression of the jugular veins, which would impede venous return and worsen intracranial pressure.

Pathophysiologically, the Monro-Kellie doctrine is relevant. According to this doctrine, the cranial cavity contains three components—brain tissue, cerebrospinal fluid, and blood—and an increase in one component must be compensated by a decrease in another to maintain normal intracranial pressure. In brainstem glioma, tumor growth increases brain tissue volume, so proper positioning helps optimize the vascular component by enhancing venous drainage.

This intervention is especially important for pediatric patients because children, though initially able to accommodate increased pressure due to unfused cranial sutures, have limited compensatory capacity and can deteriorate rapidly. Tumors in the brainstem location are particularly dangerous as they affect vital functions, including the respiratory and cardiac centers.

Immediate positioning adjustment is a fundamental nursing intervention that should be performed alongside or before other treatments, making it the priority action in this emergency situation.

## 심화 해설

Clinical Judgment
This question assesses priority nursing interventions in an emergency situation of acute increased intracranial pressure (ICP) due to a brainstem glioma. The patient's presentation of decerebrate posturing, irregular respirations, and widening pulse pressure is **Cushing's triad**, Notify HCP! signifying progressive brainstem compression and a life-threatening condition. In this situation, the nurse's first action is to select a **basic intervention that can be implemented immediately, does not require waiting for a prescription, and minimizes further injury**. Positioning adjustment (head of bed elevated 30 degrees, neutral alignment) is a critical primary intervention that promotes cerebral venous return to immediately reduce intracranial volume and buy time while more invasive treatments (such as mannitol administration) are being prepared.

Memory Tip: **P**ositioning is **P**riority for **P**ressure! When ICP is elevated, check the **P**osition first before waiting for a prescription. **HOB 30, Neutral Neck** is the standard.

KR vs US: The principles of positioning management for patients with increased ICP are the same in both Korea and the US. However, in the US NGN exam, questions often prioritize "a safe, independent nursing intervention that can be performed immediately upon reporting" over "reporting to the physician and waiting for a prescription." Administering prescribed medication is an important intervention, but positioning adjustment must absolutely precede it.

## 임상 시나리오

Clinical Practice Guide
Positioning management for patients with increased intracranial pressure: Elevate the head of bed (HOB) to about 30 degrees, and maintain neutral alignment with the neck straight. Turning the neck to the side, bending it, or leaning against the bed rails can compress the jugular veins, obstruct venous return, and further increase intracranial pressure.
Caution: In SATA (Select All That Apply) questions, if both "positioning adjustment" and "mannitol administration" appear as options, "what can be implemented immediately (positioning adjustment)" takes priority over "what is implemented after a prescription (medication administration)." Also, remember that the Trendelenburg position is an absolutely contraindicated posture that worsens intracranial pressure.

## 핵심 개념

- **Brainstem Glioma (뇌간 교종)** — A tumor that occurs in the brainstem. The brainstem houses vital centers essential for sustaining life, such as those controlling breathing, heartbeat, and blood pressure, so tumors in this area are extremely dangerous and can quickly cause symptoms of increased intracranial pressure.
- **Increased Intracranial Pressure (ICP) (두개내압 상승)** — A condition in which the pressure inside the cranial cavity is abnormally elevated. It can be caused by brain tumors, hemorrhage, edema, etc., and is an emergency situation that can lead to brain herniation and death.
- **Cushing's Triad (쿠싱 삼징후)** — Late-stage signs of severe increased intracranial pressure include: 1) widening pulse pressure due to elevated systolic blood pressure and decreased diastolic blood pressure, 2) bradycardia, and 3) irregular respirations. (In this case, bradycardia is not specified, but the other two signs appear along with decerebrate rigidity.)
- **Decerebrate Posturing (제뇌경직 자세)** — Pathological posturing indicating brainstem injury. The patient extends and internally rotates the arms and legs, with ankle flexion. This signifies damage at or above the midbrain level and carries a poor prognosis.
- **Mannitol (만니톨)** — Osmotic diuretic. It increases intravascular osmotic pressure to draw water from brain tissue into the blood vessels, reducing cerebral edema and lowering intracranial pressure. It is administered by rapid intravenous injection.
