Ch 14 Oxygenation

Front

Oxygen rate for older adult with chronic emphysema in respiratory distress?

Back

2 L/min

Answer explanation

Administering O2 at more than 2 L/min to a person with chronic pulmonary disease may cause respiratory failure.

Front

What is the recommended fluid for a patient receiving home O2 therapy to keep bronchial secretions liquefied?

Back

Water

Answer explanation

Water is the best option. Drinks with caffeine, sugar, or dairy products are not helpful to liquefy secretions.

Front

Purpose of intermittently inflated cuff in cuffed tracheostomy?

Back

Prevent aspiration when eating.

Answer explanation

The cuff is inflated to prevent aspiration while eating or when cleaning the tracheostomy tube.

Front

Appropriate nursing measure for tracheostomy care?

Back

Insert the catheter without suction.

Answer explanation

Insertion of the suction catheter without suction reduces the probability of tissue injury. Sterile gloves should be used for tracheostomy care. Suctioning should be done for a maximum of 10 seconds at a time. A used catheter should be disposed of appropriately.

Front

An 80-year-old male patient with pneumonia is on oxygen via nasal cannula at 2 L/min. Respirations: 24/min, PaO2: 88 mm Hg, pink skin tone. What action should the nurse implement?

Back

Record PaO2 level.

Answer explanation

The nurse would document PaO2 level. Normal arterial oxygen levels sometimes decrease with age, but not usually low enough to fall outside the normal range. It may be possible for an 80-year-old person to have an arterial partial pressure oxygen (PaO2) level (the amount of oxygen found in the arterial circulation) between 80 and 85 mm Hg (normal range is 80 to 100 mm Hg) without experiencing significant alterations in health.

Front

What is the appropriate value for the Venturi mask? Oxygen delivery devices with percent of oxygen delivered.

Back

4–10 L/min = 24%–55% O2

Front

A _____________ cannula is a device consisting of small tubes inserted into the nares and is the most common way to administer oxygen.

Back

nasal

Answer explanation

A nasal cannula is device consisting of small tubes inserted into the nares and is the most common way to administer oxygen.

Front

When suctioning a tracheostomy suction may be applied for a maximum of __ seconds at a time never longer.

Back

10

Answer explanation

Suctioning should be done for a maximum of 10 seconds at a time. Prolonged suctioning depletes oxygen supply.

Front

What is true regarding a patient who receives oxygen via the transtracheal method?

Back

Oxygenation is usually achieved with less oxygen flow than with other systems.

Answer explanation

The transtracheal method of receiving oxygen allows the flow rate to be decreased.

Front

Which skill can be delegated to staff other than licensed personnel? Options: IV therapy, Ear irrigation, Cold compress application, Eye irrigation

Back

Cold compress application

Answer explanation

Application of a cold compress can be delegated by the nurse; it does not require a skill or knowledge. IV therapy, ear irrigation, and eye irrigation require skill and knowledge acquired by a nurse.
