You should increase the​ patient’s oxygen flow rate to improve tissue oxygenation.

Question 7

Which of the following statements best describes the exchange of gas in the​ alveoli?

Answer 7

Air moves into the​ alveoli, blood is transported by the pulmonary​ capillaries, and diffusion occurs.

A​ 21-year-old patient presents with labored breathing and audible​ wheezes, heart rate of​ 124, respiration​ 36; he has significantly altered mentation. What is the treatment for this​ patient?
A​ 21-year-old patient presents with labored breathing and audible​ wheezes, heart rate of​ 124, respiration​ 36; he has significantly altered mentation. What is the treatment for this​ patient?

Answer 8

Ventilate with a​ bag-valve mask with high oxygen or FROPVD.

Question 9

Which of the following can cause respiratory​ depression?Which of the following can cause respiratory​ depression?

Answer 9

​End-stage COPD changes the stimulus to breathe from high carbon dioxide levels to low oxygen​ levels, causing breathing to become depressed when oxygen is administered.

Question 10

What is the percentage of oxygen provided by connecting a high flow of oxygen to the oxygen inlet found on a pocket​ mask?

Answer 10

50%

Question 11

You and your EMT partner are preparing to ventilate an elderly​ non-trauma patient who has a stoma. Your partner performs the​ head-tilt, chin-lift maneuver and you ask him to return the​ patient’s head to a neutral position.​ “Why? This is not a pediatric​ patient!” your partner protests. What would you​ say?

Answer 11

It is not necessary to position the airway of a stoma breather when providing ventilations.

Question 12

The movement of oxygen and carbon dioxide between the alveoli and circulating blood is​ called:

Answer 12

pulmonary respiration

Question 13

Why does a patient involved in an auto crash who has major internal abdominal bleeding require oxygen to maintain internal​ respiration?

Answer 13

A lack of circulating volume decreases the oxygen and carbon dioxide transport capability of the blood.

Question 14

The movement of oxygen and carbon dioxide across the cell membranes from the capillaries is​ called:

Answer 14

internal respiration.

Question 15

A​ 16-year-old patient presents with labored breathing and increased respiratory​ rate, increased heart​ rate, and leaning forward with his hands on his knees. His skin is a normal color and his pulse oximetry is 96. This patient is suffering from​ respiratory:

Answer 15

distress

Question 16

What are the signs of​ hypoxia?

Answer 16

Cyanosis​ (blue or gray​ skin) and deterioration of the​ patient’s mental status

Question 17

You are aggressively ventilating an adult patient with a​ bag-valve mask when you notice that his previously strong pulse is getting weaker. You​ should:

Answer 17

reduce the volume of the ventilations.

Question 18

Which of the following is acceptable for maintaining a seal between an oxygen cylinder and​ regulator?

Answer 18

gasket

Question 19

You are transporting a​ 44-year-old female with chest pain and sudden respiratory distress. She is​ agitated, anxious, and refuses to have a nonrebreather mask applied. Which of the following is the best​ option?

Answer 19

use a nasal cannula instead

Question 20

Venturi masks are designed to mix oxygen​ with:

Answer 20

inhaled air

Question 21

Which of the following oxygen cylinders would normally run out after 50 minutes when flowing at 10 liters per​ minute? Assume a pressure of​ 2,000 psi displayed on the pressure gauge.

Answer 21

E cylinder

Question 22

The process of air moving in and out of the chest is​ called:

Answer 22

ventilation

Question 23

A nonrebreather mask at 12 to 15 liters per minute will generally provide the patient what percentage of​ oxygen?

Answer 23

80-90

Question 24

What two measurements are multiplied to calculate the minute​ volume?

Answer 24

Tidal volume and respiratory rate

Question 25

While ventilating an intubated patient with a​ bag-valve-mask-unit, you notice increased resistance to the ventilations. This may indicate​ that:

Answer 25

air is escaping through a hole in the lung and filling the pleural space.

Question 26

What signs and symptoms would indicate inadequate breathing in a​ patient?

Answer 26

Increased effort to​ breathe, cyanosis, clammy​ skin, altered mental status

Question 27

A​ ________ is not typically used in the prehospital setting for oxygen administration.

Answer 27

partial rebreather mask

Question 28

Your patient is a motorcyclist who was ejected after striking a guard rail. The patient is unresponsive to painful stimuli and is breathing shallowly six to eight times per minute. Which of the following should you do​ first?

Answer 28

Use a​ bag-valve mask with supplemental oxygen.

Question 29

Of the three types of oxygen​ flowmeters, which one can only be used​ upright?

Answer 29

​Pressure-compensated flowmeter

Question 30

The oxygen flow rate for a nasal cannula should not exceed​ ________ liters per minute.

Answer 30

6

Question 31

Why is inhalation described as an active​ process?

Answer 31

It requires chest muscles to contract and use energy to​ move, creating a negative pressure.

Question 32

Which of the following describes why fast respiration may decrease minute​ volume?

Answer 32

The lungs may not have adequate time to fill and exchange gas.

Question 33

Which of the following is necessary to deliver oxygen to patients at a safe​ pressure?

Answer 33

regulator

Question 34

The normal urge to breathe is stimulated by chemoreceptors that measure changing levels of what two​ gases?

Answer 34

O2 CO2

Question 35

Your patient is a​ 65-year-old male with a history of COPD. He is sitting up and complaining of a severe shortness of breath. You​ should:

Answer 35

apply a nonrebreather mask giving 15 lpm of oxygen.

Answer 36

200

Question 37

Answer 37

It pushes the​ patient's vocal cords into the​ paramedic's view.
