Most common inexpensive device. It is easy to apply and permits some
freedom of movement.

Answer 9

Nasal cannula/Nasal prongs

Question 10

Concentration of nasal cannula:

Answer 10

Low concentration of O2 (24–25%) at 2-6L/min.

Question 11

Covers the client’s nose and mouth. Exhalation ports on the sides of the mask allow exhaled carbon dioxide to escape.

Answer 11

Face mask

Question 12

Delivers oxygen concentrations from 40–60% at 5–8L/min.

Answer 12

Simple face mask

Question 13

The oxygen reservoir bag that is attached allows the client to rebreathe about the first 1/3 of the
exhaled air in conjunction with
oxygen.

Answer 13

Partial rebreather mask

Question 14

Concentration of partial rebreather mask:

Answer 14

O2 of 60–90% at 6–10L/min.

Question 15

The bag of the partial rebreather mask must not totally deflate during inspiration to avoid:

Answer 15

CO2 buildup

Question 16

One-way valves are located on the
mask and between the reservoir and mask to prevent the room air and client’s exhaled air from entering the bag.

Answer 16

Non-rebreather mask

Question 17

Concentration of the non-rebreather mask:

Answer 17

Highest O2 concentration (95–100%) at 10–15L/min.

Question 18

Has wide-bore tubing and color-coded jet adapters that correspond to precise oxygen concentrations and liter flow.

Answer 18

Venturi mask

Question 19

Concentration of the Venturi mask:

Answer 19

O2 of 24–20% or 50% at 4-10L/min.

Question 20

Can replace oxygen masks when masks are poorly tolerated by the patient.

Answer 20

Face tent

Question 21

Concentration of the face tent:

Answer 21

O2 of 30–50%at 4-5L/min.

Question 22

Used for oxygen-dependent
clients. Oxygen is delivered via a cannula, surgically inserted into the trachea. The client requires less oxygen because all of the flow delivered enters the lungs.

Answer 22

Transtracheal Oxygen Delivery

Question 23

It holds the catheter in place.

Answer 23

Chain around the neck

Question 24

How to keep the catheter patent?

Answer 24

Clean the rod in and out of it. Then,
inject again 1.5mL of NSS for 2–3 times a day.

Question 25

A rigid plastic dome that encloses an infant’s head. Gas should not be allowed to be blown directly into the infant’s face.

Answer 25

Oxygen hood

Question 26

A rectangular, clear, plastic canopy with outlets that connect to an oxygen source and humidifier.

Answer 26

Oxygen tent

Question 27

Cover the child in an oxygen tent with a gown or cotton blanket to protect:

Answer 27

against chilling

Question 28

Flood the oxygen tent with:

Answer 28

15L/min for about 5min., then adjust to 10–15L/min.
