pleurisy.

Irritation or damage to the pleural surfaces that causes sharp chest pain during inhalation is called: Question 8 options: 1) pleurisy. 2) dyspnea. 3) pneumonitis. 4) pneumothorax.

pleurisy.

In order to avoid exacerbating a patient's injury, it is especially important to use extreme caution when providing positive-pressure ventilation to patients with a: Question 10 options: 1) flail chest. 2) pneumothorax. 3) cardiac tamponade. 4) myocardial contusion.

pneumothorax

A 28-year-old male was struck in the chest with a baseball bat during an altercation. He is conscious and alert and complains of severe chest pain. Your assessment reveals a large area of ecchymosis over the sternum and a rapid, irregular pulse. In addition to providing supplemental oxygen, you should: Question 4 options: 1) apply an AED and assess his BP. 2) prepare for immediate transport. 3) determine if he has cardiac problems. 4) apply bulky dressings to the sternum.

prepare for immediate transport.

Because the depth of an open abdominal wound is often difficult to determine: Question 5 options: 1) vital signs should be monitored frequently. 2) prompt transport to the hospital is essential. 3) the EMT must perform a thorough exam. 4) the abdomen must be vigorously palpated.

prompt transport to the hospital is essential.

You are transporting a 28-year-old man with a frostbitten foot. The patient's vital signs are stable and he denies any other injuries or symptoms. The weather is treacherous and your transport time to the hospital is approximately 45 minutes. During transport, you should: Question 8 options: 1) rewarm his foot in 102°F to 104°F (38.9°C to 40°C) water. 2) administer oxygen via a nonrebreathing mask. 3) cover his foot with chemical heat compresses. 4) protect the affected part from further injury.

protect the affected part from further injury.

Following blunt trauma to the chest, an 18-year-old female presents with respiratory distress, shallow breathing, and cyanosis. Her blood pressure is 80/50 mm Hg and her pulse is 130 beats/min and thready. You should: Question 9 options: 1) apply 100% oxygen via a nonrebreathing mask. 2) place her supine and elevate her lower extremities. 3) perform a rapid head-to-toe physical assessment. 4) provide ventilation assistance with a BVM.

provide ventilation assistance with a BVM.

A man called EMS 12 hours after injuring his chest. Your assessment reveals a flail segment to the right side of the chest. The patient is experiencing respiratory distress and his oxygen saturation is 78%. His breath sounds are equal bilaterally and his jugular veins are normal. You should suspect: Question 9 options: 1) traumatic asphyxia. 2) pulmonary contusion. 3) massive hemothorax. 4) tension pneumothorax.

pulmonary contusion.

The two MOST efficient ways for the body to eliminate excess heat are: Question 9 options: 1) respiration and bradycardia. 2) perspiration and tachycardia. 3) sweating and vasodilation. 4) hyperventilation and tachycardia.

sweating and vasodilation.

Common signs and symptoms of a chest injury include all of the following, EXCEPT: Question 6 options: 1) tachypnea. 2) hematemesis. 3) localized pain. 4) chest wall ecchymosis.

tachypnea.

Elevation of the rib cage during inhalation occurs when: Question 4 options: 1) the diaphragm descends. 2) abdominal contents descend. 3) intrathoracic pressure decreases. 4) the intercostal muscles contract.

the intercostal muscles contract.

Very young children tend to breathe predominantly with their diaphragm because: Question 2 options: 1) their chest wall and ribs are very pliable. 2) they require less tidal volume per breath. 3) their intercostal muscles are not fully developed. 4) there is no nerve innervation of the intercostal muscles.

their intercostal muscles are not fully developed.
