NPS EXAM WITH WELL DETAILED QUESTION &
ANSWERS PERFECTLY A+ GRADED WITH RATIONALE
NEW UPDATE
Whats the most common O2 administration device used for a neonate and what starting FiO2 (if
not previously on O2) CORRECT ANSWER>>>>Oxygen Hood 30-45%
What is the flow rate range of an oxygen hood that will ensure adequate flushing of CO2
CORRECT ANSWER>>>>7-15 L/m
Humidity or heated aerosol provided with oxygen hood should be delivered at what temp.
range CORRECT ANSWER>>>>30 - 34 C
Where is the best place to analyze O2 within the oxygen hood and why CORRECT
ANSWER>>>>At the infants mouth because O2 has a tendency to settle and the bottom.
(↑FiO2 at bottom than at the top)
How can excessive noise from a nebulizer (air-entrainment) transmitted to the oxygen hood be
reduced so that hearing damage and restlessness in the neonate can be prevented
CORRECT ANSWER>>>>Use Air-O2 blender to acheive precise FiO2 (quieter than air
entraiment port) and set aerosol mask at 100%
,Why is temperature regulation in the oxygen hood important CORRECT
ANSWER>>>>If too cool then O2 consumption will ↑
If too warm then apnea and insensible water loss (dehydration) can occur
[Keep temp. between 30 - 34C]
What is the minimum age for use of a non-rebreather mask CORRECT
ANSWER>>>>Peds at least 1 year old
Max FiO2 of NRB CORRECT ANSWER>>>>100%
If the reservoir bag NRB collapses completely with each breathe then... CORRECT
ANSWER>>>>Flow is insufficient...INCREASE THE FLOW
Troubleshooting a NRB mask whose reservoir bag does not collapse at all with each breath
involves... CORRECT ANSWER>>>>1. Proper sealing of mask on face (POOR SEAL IS
MOST COMMON CAUSE)
2. Replace mask due to faulty NRB valve
If the reservoir bag of an NRB does not collapse with each breathe, and a loud "hissing sound" is
heard form the flow meter then... CORRECT ANSWER>>>>the flow is set too high
(reduce the flow)
What O2 device should be used for a pt whose has irregular Vt and erractive RR
CORRECT ANSWER>>>>Venturi Mask
, In order for venti mask to be effective, what should it accomplish with regard the the pts.
breathing CORRECT ANSWER>>>>Meet or exceed pt inspiratory demand
How do you know if a venti mask is meeting or exceeding a pt inspiratory CORRECT
ANSWER>>>>Total flow of device must be greater than the pt VE
How do you calculate total flow CORRECT ANSWER>>>>Magic Box then add parts.
Sum of the parts x set flow = total flow of device
Compare total flow to pt VE
NC are better suited for neonates or peds?
(Not HFNC) CORRECT ANSWER>>>>Peds
What is the achievable FiO2 with a NC on a neonate?
What is the achievable FiO2 with a NC on a ped? CORRECT ANSWER>>>>60%
45%
(Peds have higher insp. demands therefore will entrian more room air and ↓ FiO2)
What is the flow rate range for a NC on a neonate CORRECT ANSWER>>>>0.25 - 2.0
L/m
Since neonatal flowmeters come in mL/min, what should a neonatal flow meter be set a to
achieve a flow of 0.25 L/m CORRECT ANSWER>>>>Set neonatal flowmeter at 250
mL/min
