Why Are There Multiple Choice Questions on Mechanical Ventilation?

In order to give high quality patient care, all health professionals near the bedside must learn about the functions, limitations, and advantages of different ventilator modes. It is also important for the health professional to understand the various ways in which a patient may adjust or react to a ventilator. Knowledge about these aspects empower those who work in the health industry to promptly identify problems and quickly take corrective actions.

1. An artificial airway, like an endotracheal tube, is used in the following type of ventilation.

A. Positive Pressure

B. Negative pressure

  • Answer: A

2. Pressure is applied to the abdomen and thorax to draw air into the lungs through the upper airway in the following type of ventilation.

A. Positive Pressure

B. Negative pressure

  • Answer: B

3. Iron lung ventilators used after the polio epidemics in the first half of the 20th century belong to...

A. Positive Pressure Ventilation

B. Negative pressure Ventilation

  • Answer: B

4. One of the following modes of ventilation “locks out” the patient's efforts to breathe.

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Assist Control Mode

D. Pressure Control Mode

  • Answer: A
ICU without mechanical ventilators.

ICU without mechanical ventilators.

5. One of the following modes of ventilation has the risk of the patient getting respiratory alkalosis.

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Assist Control Mode

D. Pressure Control Mode

  • Answer: C

6. The mode of ventilation which allows the patient to breathe spontaneously at his or her own respiratory rate and depth between the ventilator breaths is...

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Assist Control Mode

D. Pressure Control Mode

  • Answer: B

7. Minute ventilation is equal to...

A. FiO2 X PEEP

B. FiO2/PEEP

C. Tidal Volume X Respiratory Rate

D. Tidal Volume/Respiratory Rate

  • Answer: C

8. What are the Ventilator Parameters adjusted to maintain the optimum Minute Ventilation?

A. FiO2 and PEEP

B. Tidal Volume and Respiratory Rate

  • Answer: B

9. Which are the Ventilator Parameters adjusted to maintain the optimum oxygenation?

A. FiO2 and PEEP

B. Tidal Volume and Respiratory Rate

  • Answer: A

10. One of the following modes of ventilation reduces the work of breathing by overcoming the resistance created by ventilator tubing.

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Assist Control Mode

D. Pressure Support Mode

  • Answer: D

11. Short Answer: What is the difference between a CPAP and a BiPAP?

CPAP is essentially a constant PEEP. BiPAP is CPAP plus Pressure support. Both these modes have shown to reduce need for intubation and mortality among COPD patients.

12. CPAP and BiPAP modes are usually used...

A. in conjunction with bronchodilators and steroids

B. to delay intubation

C. as a weaning protocol

D. All of the above

  • Answer: D

13. Which one of the following modes of ventilation is triggered by time, limited by pressure and affects aspiration only?

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Assist Control Mode

D. Pressure Control Mode

  • Answer: D

14. There can be variations in the minute ventilation in one of the following modes of ventilation as the respiratory rate and tidal volume is determined by the

A. Controlled Mandatory Ventilation

B. Synchronous Intermittent Mandatory Ventilation

C. Pressure Control Mode

D. Pressure Support Mode

  • Answer: D

15. Which of the following conditions require a higher PEEP to be applied in recruiting collapsed alveoli?

A. Asthma

B. Acute Respiratory Distress Syndrome

C. Bronchietasis

D. Emphysema

  • Answer: B

16. One of the following is a risk of keeping high PEEP

A. Hypotension

B. Hypertension

C. Hyperthermia

D. Hypothermia

  • Answer: A

Good Evening JR Khisna,

i'm Azila from Malaysia interested to get your permission for using your questionnaire for using collection data for my research which way it's in progress right now. I hope that u will reply my email as soon as possible because I need your permission before I can adapt the questionnaire in my research. Tq for your attention.

thanks :)

My brother became septic after bowel blockage , kept him alive til all family members could get to the hospital, don' t remember seeing any tubes, I do remember when we all arrived and said our goodbyes the dr asked him if he was comfortable and looked like he was controlling a machine, would like to know how he was kept alive

Hi sciddharthakoonwar@kgmcindia.edu ,

Hi Siddarth

This material is free of cost

sciddharthakoonwar@kgmcindia.edu on October 20, 2017:

It was rather is of great use to me. But my appetite is huge and pocket empty. can I get such academic material regularly free of cost for the benefit of my own and my critical care pediatric patients and residents ? if yes the how ??

JR Krishna (author) from India on February 05, 2017:

Dear Fahad,

Please share the article in your friends' circle

These are important mcqs for students of medicine, nursing, respiratory therapy and physiotherapy.

Many thanks

Hi Bethany

I am glad that that answer could be of use to you.

You are most welcome for any further clarifications :)

Bethany Segovia from Texas on September 25, 2015:

Thanks for the reply! I was just curious as to if there were some distinguishing features between the two. Being new to the field, it's great to have a perspective on terminology that may not be taught anymore, but that is still thrown around. There's nothing worse than talking to a doctor and hearing a term you aren't familiar with in the hospital atmosphere. Thanks for the learning opportunity.

JR Krishna (author) from India on September 25, 2015:

Hi Bethany

Both terms mean the same. "controlled mechanical ventilation" is relatively an older terminology. I mean when we were (older generation) were students, we were taught is "controlled mechanical ventilation or "controlled mandatory ventilation.

Now you are using the term "continuous mechanical ventilation"

The characteristics are same

However, now a days we hardly see this mode being used

It was a very common mode for post neuro-surgical patients in the 90s

Patients were given sedation and muscle paralysing agents along with CMV

Bethany Segovia from Texas on September 25, 2015:

I enjoyed your MCQs, however I'm curious about the term "controlled mechanical ventilation." The term I am familiar with is "continuous mechanical ventilation" and have always been taught that it is interchangeable with assist-control. Just trying to compare my knowledge base to yours! :)

JR Krishna (author) from India on January 07, 2014:

I m sorry for your loss.

my dad died after being sedated because he refused to take the oxegen tank

Hi DDE,

Thanks for the visit
