4 A tension pneumothorax is life threatening and requires immediate intervention. On inspiration, air enters the pleural space, does not escape on expiration, and increases the intrapleural pressure. This pressure collapses the injured lung and shifts the mediastinal contents, compressing the heart, great vessels, trachea, and eventually the uninjured lung.

The emergency department nurse is triaging patients. Which patient should be prioritized? 1) An adult patient experiencing mild chest pain 2) An adolescent patient with a possible fractured wrist 3) An older adult patient with a hip fracture who is in pain 4) A school-age patient with asthma presenting with dyspnea

4 According to the Five-Level Emergency Severity Index (ESI), a patient experiencing severe respiratory distress such as the school-age patient with asthma who is having difficulty breathing (dyspnea) would receive priority care as an ESI-1.

The first step in the management of a patient being treated for hyperthermia includes which nursing action? 1. Inserting an indwelling catheter 2. Initiating intravenous access 3. Implementing low flow oxygen 4. Relocating to a cool environment

4 All interventions for hyperthermia start with removal to a cooler environment and hydration. Heat stress or heat edema may require nothing more than removing to a cooler environment. The patient with heat syncope requires safety maneuvers to help prevent injury from falling. After being gently helped to the floor, the patient should be placed in the recovery position until full recovery of consciousness. Heat cramping requires rehydration with oral fluids containing electrolytes to correct the fluid and electrolyte loss.

4 Because the majority of gunshot wounds require an investigation by law enforcement, nurses working in emergency departments and trauma centers should be familiar with their agency's protocols for maintaining evidence required by law enforcement. Often, law enforcement does not want the victim's hands or the area around the victim's wounds cleansed. Clothes and personal items are often wanted as evidence. The nurse should not bathe the patient and provide a clean gown. The nurse should not ask the patient who shot him or where the weapon is. The nurse should preserve the chain of evidence.

The nurse monitors for which acid-base disorder in the patient with early hypothermia? 1. Metabolic acidosis 2. Metabolic alkalosis 3. Respiratory acidosis 4. Respiratory alkalosis

4 Mild hypothermia is when the body's core temperature is 89.6°F to 95°F (32°C to 35°C). The human body tries to compensate for decreases in body temperature by stimulating the sympathetic nervous system to shiver and increase heart rate, blood pressure, respirations, and promote peripheral vasoconstriction. Tachypnea causes a decrease in carbon dioxide (CO2) levels, resulting in a respiratory alkalosis.

The nurse is providing care to several patients in the emergency department. Which patient is the priority when using the three-tiered triage system? 1) A patient with a simple fracture 2) A patient experiencing renal colic 3) A patient with severe abdominal pain 4) A patient with chest pain and diaphoresis

Which nursing actions are appropriate during the primary survey of the emergency assessment process? Select all that apply. 1) Inserting a nasogastric tube 2) Immobilizing the cervical spine 3) Arranging for diagnostic studies 4) Preparing for chest tube insertion 5) Applying direct pressure to a wound

2 4 5 The primary survey focuses on airway, breathing, circulation (ABC), disability, and exposure or environmental control. It aims to identify life-threatening conditions so that appropriate interventions can be started. Nursing actions that are appropriate during the primary survey include immobilizing the cervical spine, preparing for chest tube insertion, and applying direct pressure to a wound.

In caring for a patient being rewarmed for treatment of hypothermia, the nurse correlates which laboratory value to "afterdrop"? 1. Calcium 14.5 mg/dL 2. Glucose 55 mg/dL 3. Sodium 150 mEq/L 4. Potassium 2.8 mEq/L

1 Rewarming the core at a prescribed rate is important to prevent significant complications. Rewarming too rapidly can cause hyperkalemia as potassium shifts out of the cells and a condition known as afterdrop. Afterdrop is defined as a precipitous reduction in core temperature due to redistribution of body heat to improperly warmed peripheral tissues, with rapid shunting of cold blood from the periphery to the core as the direct result of vasodilation. This causes a bolus of cold, hyperkalemic, acidotic blood to return from the periphery to the heart, which results in a biochemical injury that leads to severe hypotension and dysrhythmias.

The nurse is conducting a secondary survey as part of the emergency assessment. Which is the priority nursing action during the health history portion of the assessment? 1) Determining drug allergies 2) Noting the general appearance 3) Examining the neck for stiffness 4) Auscultating for heart and lung sounds
