What is the normal intracranial pressure (ICP) range the nurse tries to maintain?

Rationale:
A. Antidiarrheal medication for diarrhea is incorrect because, although diarrhea can contribute to fluid loss, administering antidiarrheals is not a priority intervention in the acute management of hypovolemic shock. Immediate life-saving measures focus on restoring circulation, oxygenation, and treating the underlying cause rather than symptom control.

B. Assist during emergency revascularization is incorrect because revascularization is primarily indicated for cardiogenic or obstructive causes of shock (such as myocardial infarction or vascular occlusion), not hypovolemic shock, which results from a loss of intravascular volume.

C. Eliminate and treat the cause of shock is correct because stopping the source of fluid loss (such as hemorrhage, dehydration, burns, or third spacing) is essential to prevent further volume depletion and progression of shock.

D. Intubate for oxygenation and ventilation is correct because patients in hypovolemic shock may have impaired oxygen delivery to tissues. Airway protection and supplemental oxygen or mechanical ventilation may be necessary to optimize oxygenation and reduce the work of breathing.

E. Replace lost volume with appropriate fluid is correct because rapid fluid resuscitation with isotonic crystalloids and/or blood products is the cornerstone of treatment for hypovolemic shock to restore circulating volume, improve cardiac output, and maintain tissue perfusion.

Rationale:
A. Rupture of a bleb is correct because spontaneous pneumothorax often occurs when a subpleural bleb ruptures, allowing air to escape into the pleural space and causing lung collapse. This is commonly seen in young, tall, thin individuals or patients with underlying lung disease.

B. Lung abscess is incorrect because a lung abscess is a localized infection with pus formation within lung tissue. While it causes inflammation and destruction of lung parenchyma, it does not typically introduce air into the pleural space unless it ruptures, which is uncommon and not considered a primary cause of pneumothorax.

C. Central line placement is correct because iatrogenic pneumothorax can occur during procedures such as subclavian or internal jugular central venous catheter insertion if the pleura or lung is accidentally punctured.

D. Dyspnea is incorrect because dyspnea is a symptom, not a cause. It commonly occurs as a result of pneumothorax but does not cause one.

E. Trauma is correct because blunt or penetrating chest trauma (such as rib fractures or stab wounds) can allow air to enter the pleural space, leading to a traumatic pneumothorax.
