Quiz 15

Which of the following statements regarding inhaled poisons is correct?

Lung damage may progress after the patient is removed from the environment

Initial dose of Narcan by the EMT is:

1 mg/nostril

Hypothermia occurs when the core body temperature falls below:

95°F (35°C)

activated charcoal administration in contraindicated in patients who have ingested

acids or alkalis

A 30-year-old male was rescued after being lost in the woods for approximately 18 hours. The outside temperature is 30°F (-1°C). He is immediately placed in the warmed ambulance, where you perform a primary assessment. He is unresponsive, pale, and apneic. You should:

assess for a carotid pulse for up to 60 second

Patients with generalized hypothermia are at an increased risk of a local cold injury because

blood is shunted away from the extremities to the body's core

EMT administration of Narcan is contraindicated in patients in

cardiac arrest

When a warm hand is immersed in water that is 70°F (21°C), heat is transferred from the hand to the water through a process called:

conduction

The transfer of heat to circulating air, such as when cool air moves across the body's surface, is called:

convection

The official transfer of patient care does not occur until the EMT:

gives an oral report to the emergency room physician or nurse

Shivering is a mechanism in which the body generates heat by:

increasing the metabolic rate

What maneuver should be used to open the airway of an unresponsive patient with suspected trauma?

jaw-thrust maneuver

narcan administered by the EMT is indicated for

morphine overdose

A frostbitten foot can be identified by the presence of:

mottling and blisters

Before giving activated charcoal, you should:

obtain approval from medical control

heroin is an

opioid

Airborne substances are diluted with:

oxygen

Your assessment of a 23-year-old female reveals a core body temperature of 93.4°F (34°C). She is conscious, answers your questions appropriately, is shivering, and complains of nausea. Her skin is cold and pale, her muscles appear rigid, and her respirations are rapid. In addition to monitoring her ABCs, administering oxygen, and turning up the heat in the back of the ambulance, you should:

place heat packs to her groin, axillae, and behind her neck; cover her with warm blankets; and avoid rough handling

A 20-year-old male was pulled from cold water by his friends. The length of his submersion is not known and was not witnessed. You perform a primary assessment and determine that the patient is apneic and has a slow, weak pulse. You should:

provide rescue breathing, remove wet clothing, immobilize his spine, keep him warm, and transport carefully

Pain that may be perceived at a distant point on the surface of the body, such as the back or shoulder, is called:

referred pain

Which of the following would be the LEAST likely to occur in a patient with a core body temperature of between 89°F (32°C) and 92°F (33°C)?

tachycardia

A person who routinely misuses a substance and requires increasing amounts to achieve the same effect is experiencing:

tolerance

All are routes for drugs except: a. transitional route b. transcutaneous c. oral d. injection

transitional route

Rough handling of a hypothermic patient with a pulse may cause:

ventricular fibrillation

A patient with spontaneous respirations is breathing:

without assistance
