Test #1

Question 1

Meaning of Myo

Answer 1

muscle

Question 1

Meaning of Gastro

Answer 1

stomach

Question 2

meaning of the suffix itis

Answer 2

inflammation

Question 3

EMTs should have a strong working knowledge of medical terminology in order to

Answer 3

perform and document more accurate patient assessments

Question 4

The central nervous system is composed of the

Answer 4

brain and spinal cord

Question 5

A by-product of involuntary muscle contraction and relaxation is

Answer 5

heat

Muscle activity generates heat as a by-product, regardless of whether it is voluntary or involuntary. This is due to the metabolic processes in the muscle cells during contraction and relaxation. Lactic acid is a by-product of anaerobic metabolism, which can occur during intense muscle activity when the oxygen supply is insufficient, but it is not specifically a by-product of involuntary muscle activity. Heat, on the other hand, is universally produced by muscles during any form of contraction.

Question 6

What are ventricles

Answer 6

ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system

Question 7

. A patient has a blood pressure of 130/70 mm Hg. The “130” in this measurement represents

Answer 7

ventricular contraction (Systolic pressure)

Question 8

If a patient’s chest barely moves during inhalation, even if the patient’s respiratory rate is normal, you should suspect that

Answer 8

minute volume is decreased

Question 9

The waste products of aerobic metabolism include

Answer 9

carbon dioxide and water

Question 10

The physical act of moving air into and out of the lungs is called

Answer 10

ventilation

Question 11

Diffusion

Answer 11

Diffusion is the process whereby gases move from an area of high pressure to low pressure. This includes during - Internal respiration - this is the movement in the internal tissues between cells and capillaries, and - External respiration - when gas is exchanged between the alveoli and lung capillaries

Question 12

Atherosclerosis is defined as

Answer 12

the buildup of plaque inside the walls of blood vessels

Question 13

The respiratory rate of 30 breaths per minute in an infant is

Answer 13

normal

Question 14

Normally, the newborn’s respiratory rate is

Answer 14

30 to 60 breaths per minute

Question 15

A palpable pulse is created by

Answer 15

pressure waves through the arteries caused by cardiac contraction

Question 16

An elderly patient has fallen and hit her head. Your initial care should focus on:

Answer 16

airway, breathing, and circulation

ABC

Question 17

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

Answer 17

Jaw-thrust maneuver

Question 18

When you shine a light into one pupil, the normal reaction of the other pupil should be to

Answer 18

become smaller

C. A 55-year-old male with a severe headache and 2 days of nausea
D. A 61-year-old female who is unconscious with facial cyanosis

Answer 19

Question 20

Upon arriving at a potentially unsafe scene, you should first

Answer 20

ensure that you are safe

Question 21

A man was found unresponsive in his bed at home on a winter morning. There is no evidence of injury and the patient’s medical history is not known. The patient’s face is cyanotic, yet the pulse oximeter reads 98%. Which of the following would MOST likely explain this?

A. Severe pulmonary edema

C. His extremities are cold
D. Increased body temperature

Answer 21

Carbon monoxide poisoning

Question 22

Answer 22

nonrebreathing mask

Question 23

hypoxic meaning

Answer 23

not having enough oxygen

Question 24

During your assessment of a patient with respiratory distress, you hear wheezing when listening to breath sounds. This indicates

Answer 24

a lower airway obstruction

Question 25

fluid in the alveoli makes what sound

Answer 25

Crackles

Question 26

During your assessment of a patient with respiratory distress, you hear wheezing when listening to breath sounds. This indicates:

Answer 26

a lower airway obstruction
