I am working through the self-quiz on Airways (chapter 6) and I'm confused by some of the answer I got wrong...
First problem: Multiple choice question 22:
Which of the following statements about oxygen administration is true?
A) Non-rebreather mask is used for 4-6 l/m
B) Nasal cannula good for 90%
C) Cylinder can explode if damaged
D) The portable cylinders used by most EMS systems are D and E
I went with D, and was told the answer is C. I am directed to page 119 for a reminder. 119 says: "The high pressure can cause an explosion if damaged" Fair enough. So why did I pick D? Well, page 118 says; "The portable oxygen cylinders used by most EMS systems are either D or E sized."
So I'm right, but I'm also wrong? Why would a multiple choice ask me to select the ONE true answer, then present me with TWO true answers and then tell me I got it wrong? I got the wrong right one, not the right right one. Right?
Am I reading this wrong? Or is this a misprint?
Second problem: True/False Question 25:
A nasal airways can only be used on an unconscious patient?
I said False. Book says TRUE. Points me to page 99 for clarification. Page 99 says; "Nasal airways can be used on both unconscious and conscious patients."
Why does it say I'm wrong? Am I missing something, or is this another misprint?
Third problem: True/False Question 30:
The most common foreign object that causes airway obstruction is food.
I said True. Book says FALSE. Sends me to page 111 for my chewing-out. Second-to-last sentence on page 111 says; "Food is the most common foreign object that causes airway obstruction."
Mind. completely. blown. So the textbook tells me that food IS the most common foreign object, but the true/false question tell me it is NOT.
So, with these three, either I am indescribably stupid or these are misprints. I cannot wrap my brain around the concept that food both IS and IS NOT the most common foreign object that... eh, you get the idea. I keep rereading the sentences over and over to see if they're being sneaky and pitting subtle differences in there that make my answers legitimately incorrect...
This begs another question... How many of the answers I supposedly got right that I actually got wrong...
