\Q\.1. What interventions might a nurse suggest for a pt with congested lungs to help thin
secretions? - ANSWERS✔-Maintaining adequate fluid intake
Patients can help keep their secretions thin by drinking 2 to 3 quarts (1.9-2.9 L ) of clear fluids
daily. Fluid intake should be increased to the maximum that the patient's health state can
tolerate.
\Q\.2. If a pt is hypoxic we can administer oxygen in several different ways. What are the
methods and what rate of oxygen do we use for each (see table 38-5)? With a high flow nasal
cannula what side effect might the flow have for the patient and what might we use to provide
comfort for the patient? - ANSWERS✔-1. Nasal cannula
Low Flow
1-2 L/min = 23%-30%
3-5 L/min = 30%-40%
6 L/min = 42%
2. Simple mask
Low Flow
6-8 L/min = 40%-60% (5 L/min is minimum setting)
3. Partial rebreather mask
Low Flow
8-11 L/min = 50%-75%
4. Nonrebreather mask
Low Flow
,12 L/min = 80%-100%
5. Venturi mask
, High Flow
4-10 L/min = 24%-40%
Side effect caused by high flow:
Oxygen dries and dehydrates the respiratory mucous membranes.
What to use for comfort:
humidifying devices (supplying 20%-40% humidity) are commonly used when oxygen is
delivered at higher flow rates. Distilled or sterile water is commonly used to humidify oxygen.
When moving patients receiving humidified oxygen, make sure that water from the humidifier
does not enter the tubing through which the oxygen is flowing. Additional suggestions for
transporting a patient with a portable oxygen tank are given in Guidelines for Nursing Care 38-2.
\Q\.3. When a patient is sick with pneumonia and her oxygen saturation is low, what does mean
on a physiological level? - ANSWERS✔-Hemoglobin carries less than normal amounts of oxygen,
carbonic acid levels go up.
Incomplete lung expansion or the collapse of alveoli, known as atelectasis, prevents pressure
changes and the exchange of gas by diffusion in the lungs. Areas of the lung with atelectasis
cannot fulfill the function of respiration
(p. 1490, 1400)
\Q\.4. Respiratory rates are different for various ages. What is a normal adult respiratory rate?
Newborn? Aged (old) adult? - ANSWERS✔-Birth - 1 year: 30-55 breaths/min
Normal adult: 12-20 breaths/min
Aged (old) adult: 16-24 breaths/min
