Q

When does respiratory distress change to respiratory​ failure?

A

When continuation of a respiratory challenge results in the systems being unable to keep up with the​ demand, and the skin color and mental status change.

Q

Your patient is a​ 55-year-old man with a history of chronic bronchitis. You have been called to his home today because of an increase in his level of respiratory distress. The patient is on 2 liters per minute of oxygen by nasal cannula at home. Your assessment reveals difficulty speaking due to shortness of​ breath, leaning forward to​ breathe, a productive​ cough, and a respiratory rate of 32 per minute. Which of the following is true concerning the best course of action for this​ patient?

A

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

Q

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

A

​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.

Q

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?

A

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

Q

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

Q

What are the signs of​ hypoxia?

A

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

17
Q

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:

A

reduce the volume of the ventilations.

18
Q

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

A

gasket

19
Q

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?

A

use a nasal cannula instead

20
Q

Venturi masks are designed to mix oxygen​ with:

A

inhaled air

21
Q

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.

A

E cylinder

22
Q

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

A

ventilation

23
Q

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

A

80-90

24
Q

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

A

Tidal volume and respiratory rate

25
Q

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

A

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

26
Q

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

A

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

27
Q

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

A

partial rebreather mask

28
Q

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?

A

Use a​ bag-valve mask with supplemental oxygen.

29
Q

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

A

​Pressure-compensated flowmeter

30
Q

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

A

6

31
Q

Why is inhalation described as an active​ process?

A

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

32
Q

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

A

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

33
Q

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

A

regulator

34
Q

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

A

O2 CO2

35
Q

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:

A

apply a nonrebreather mask giving 15 lpm of oxygen.

36
Q

The safe residual for an oxygen cylinder is​ ________ psi.

A

200

37
Q

The paramedic is intubating a patient and asks you to assist by gently pressing your thumb and index finger to either side of the throat just over the​ patient’s Adam’s apple. As you​ press, you gently direct the throat upward and to the​ patient’s right. What is the purpose of this​ maneuver?

A

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