Questions and Answers

1.

I hate fill in the blank because it is impossible to get everybody to enter the same thing, and there is nothing more frustrating then getting a question wrong just because you used a capital letter. Oh well, let's do it anyway, just follow the rules! Oxygen toxicity is caused as a result of ____ ________. (2 words, 1st word 4 letters, 2nd 8 letters all lower case with a space inbetween)

Correct Answer
free radicals
Free Radicals
free radical
Free radical
freeradical

Explanation
Oxygen free radicals are byproducts of cellular metabolism that can damage or kill cells if they get out of control.

2.

Oxygen toxicity primarily affects the _____ and the ___. (2 words, first word 5 letters, second "word" 3 letters, 1 space in between, and once again all lower case)

Correct Answer
lungs cns
lungs CNS
Lungs CNS
Lungs cns
lungs central nervous system

Explanation
Oxygen toxicity primarily affects the lungs and the central nervous system (CNS).

3.

The two primary factors of O2 toxicity are PIO2 AND exposure time.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The partial pressure of inspired O2 and the time exposed to it are the primary factors.

Rate this question:
4.

CNS effects only occur at pressures lower than 1ATM.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
CNS effects usually only happen when a patient is breathing oxygen at pressures greater than 1ATM, and although they probably could (and do) occur at less, the "only" is the falsifier here.

Rate this question:
5.

Damage to lung tissue can occur at clinical O2 levels.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
According to Egan's this is a true statement (p.870)

Rate this question:
6.

What is the vasoconstrictive reaction that causes necrosis and proliferation of vessels leading to scar tissue, retinal detachment, and possible blindness in newborns called? (1 of it's names anyway, I've seen at least 3 so far)
- A.
  
  Retinology of Newborn
- B.
  
  Rhinoplasty of Newborn
- C.
  
  Rhinoceritis Prematurus
- D.
  
  Retinopathy of Newborn
- E.
  
  NOTA
Correct Answer
D. Retinopathy of Newborn

Explanation
Retinopathy of Newborn, Retinopathy of Prematurity (ROP), or Retrolental Fibroplasia. Retinopathy of Newborn is what we called it in class. The other stuff is made up, although I guess you could give a newborn a nose-job (rhinoplasty).

Absorption atelectasis is a reaction to increased FIO2 that results in a decrease in:
- A.
  
  CO2
- B.
  
  N2
- C.
  
  PAO2
- D.
  
  H2
- E.
  
  AOTA
- F.
  
  NOTA
Correct Answer
B. N2

Explanation
Absorption atelectasis occurs as high levels of O2 push N2 out of the blood and cause rapid decrease of total pressure of venous gasses. This can lead to lung collapse, especially if alveoli become obstructed.

Rate this question:
8.

Absorption atelectasis can occur in patients breathing room air.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Low tidal volumes in semi-conscious or unconscious patients can possibly lead to this situation.

Rate this question:
9.

According to the book (Egan's p.872) this is a natural response that prevents absorption atelectasis in alert individuals.
- A.
  
  Sigh
- B.
  
  Cough
- C.
  
  Hiccup
- D.
  
  Belch
- E.
  
  NOTA
Correct Answer
A. Sigh

Explanation
Sighing or what I think they mean yawning supposedly periodically hyperinflates the lung.

Rate this question:
10.

Major alveolar injury occurs after the exudative phase in pulmonary injury of hypoxia.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Major alveolar injury occurs first and as the type I cells are destroyed type II cells develop causing super surfactant slip n' slide (exudative phase) that can then lead to fibrosis as hyaline membranes form in the damaged alveolar regions.

11.

The "goal" of O2 therapy is to have the patient:
- A.
  
  At 100% for less than 24 hours
- B.
  
  Decreased to 70% within 2 days
- C.
  
  Decreased to 50% or less within 5 days
- D.
  
  AOTA
Correct Answer
D. AOTA

Explanation
The "true goal" is to use the lowest FIO2 with adequate tissue oxygenation, but this is the rule of thumb info off of page 871 that was also presented in lecture.

Rate this question:
12.

It is ALWAYS necessary to ween patients from 100% O2 within the 24 hour window.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
If your patient needs the O2 you give it to them. Sparing them from any effects of oxygen toxicity isn't going to do them any good if they suffer tissue damage from hypoxia.

Rate this question:
13.

Adults can usually breathe 50% FIO2 for extended periods of time without any damage.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
P.871 of Egan's
