Question 1

Which of the following are acceptable methods of documenting the presence of hypoxemia in patients being considered for home O₂ therapy? I.blood gas analysis II.pulse oximetry III.physical exam

Accepted Answer

Both blood gas analysis and pulse oximetry are accepted methods of documenting hypoxemia in patients being considered for home oxygen therapy. Physical exam alone may not provide accurate information on the presence of hypoxemia. Therefore, options A (I and II) is the best choice.

Question 2

Which of the following is FALSE about home O₂ therapy?

Accepted Answer

A PRN (as needed) prescription for O₂ is not acceptable because O₂ typically requires continuous therapy to be effective.

Question 3

In addition to specifying the liter flow or concentration, which of the following must a physician include in a home O₂ prescription? I.evidence of central cyanosis II.appropriate medical diagnosis III.laboratory evidence of hypoxemia IV.frequency of use of O₂ V.duration of need for O₂

Accepted Answer

A prescription for home oxygen therapy must include an appropriate medical diagnosis, laboratory evidence of hypoxemia, the frequency of use, and the duration of need for oxygen.

Question 4

A home care patient will be receiving nasal O₂ at 0.5 L/min using a large compressed gas cylinder. Which of the following additional equipment would you specify for this patient? I.bubble humidifier II.pressure-reducing valve III.calibrated low-flow flowmeter

Accepted Answer

A pressure-reducing valve is necessary to safely reduce the high pressure from the gas cylinder to a usable level. A calibrated low-flow flowmeter is needed to accurately deliver the low flow rate of 0.5 L/min. A bubble humidifier is not typically required at such low flow rates.

Question 5

Which of the following are acceptable indicators of hypoxemia for purposes of justifying home O₂therapy? I.resting PaO₂ of 65 mm Hg (room air) II.drop in Sao₂ below 89% during ambulation III.resting arterial SaO₂ below 88% (room air)

Accepted Answer

All listed indicators (resting PaO2 of 65 mm Hg on room air, drop in SaO2 below 89% during ambulation, and resting arterial SaO2 below 88% on room air) are acceptable indicators of hypoxemia for justifying home oxygen therapy.

Question 6

Once the need for long-term home O₂ therapy has been documented, why should repeated laboratory assessment (ABG or oximetry) be conducted? I.to follow the course of the disease II.to assess changes in clinical status III.to facilitate changes in the prescription

Accepted Answer

Repeated laboratory assessments are necessary to follow the course of the disease, assess changes in clinical status, and facilitate changes in the prescription. This ensures that the patient is receiving the appropriate level of therapy and is not being over or under-treated.

Question 7

Home O₂ can be supplied by which of the following systems? I.REDOX chemical reactors II.liquid O₂ systems III.O₂concentrators

Accepted Answer

Liquid O₂ systems and O₂ concentrators are commonly used for home oxygen supply. REDOX chemical reactors are not typically used for this purpose.

Question 8

Durable medical equipment (DME) companies usually provide which of the following respiratory home care services?
I.third-party insurance processing
II.most respiratory care modalities
III.24-hours/7-days-a-week service
IV.home instruction and follow-up

Accepted Answer

Durable medical equipment (DME) companies typically offer a comprehensive range of services to support patients requiring respiratory home care. This includes processing third-party insurance claims (I), providing a variety of respiratory care modalities (II), offering round-the-clock service (III), and delivering home instruction and follow-up care (IV). These services ensure patients receive the necessary equipment and support for their respiratory needs in a home setting.

Question 9

What is the primary use of compressed O₂ cylinders in alternative settings? I.ambulation (small cylinders) II.backup supply (large cylinders) III.primary supply (large cylinders)

Accepted Answer

Compressed O2 (oxygen) cylinders are primarily used for ambulation with small cylinders to allow patients mobility and as a backup supply with large cylinders in case of emergency or when the primary supply system fails. They are not typically used as the primary supply, especially in alternative settings where other systems are usually in place for that purpose.

Question 10

What is the most common respiratory home care modality?

Accepted Answer

The answer of What is the most common respiratory home...

Question 11

Key environmental factors that should be assessed in considering discharge of a patient to the home care setting include all of the following except:

Accepted Answer

The answer of Key environmental factors that should be assessed...

Question 12

HCFA regulations require that prescriptions for home O₂therapy be based on:

Accepted Answer

HCFA regulations specify that prescriptions for home oxygen therapy must be based on documented hypoxemia, which is a lower than normal level of oxygen in the blood.

Question 13

Factors to consider when advising a patient on selection of durable medical equipment (DME) include all of the following except:

Accepted Answer

Finder's fees should not be a factor to consider when advising a patient on selection of durable medical equipment (DME) as it can be seen as a conflict of interest and can compromise the quality of care provided to the patient. Accreditation, cost, and availability are all important factors to consider to ensure the patient receives appropriate and effective DME.

Question 14

Advantages of using compressed O₂ cylinders in the home include which of the following? I.minimal waste or loss II.unlimited storage time III.widespread availability IV.minimal user hazards

Accepted Answer

Compressed O2 cylinders have minimal waste or loss, unlimited storage time, and are widely available, making options I, II, and III correct. However, they do not necessarily have minimal user hazards, so IV is incorrect.

Question 15

Home O₂ therapy can be justified in patients with PaO₂ values greater than 55 mm Hg in all of the following conditions except:

Accepted Answer

Home oxygen therapy is indicated in patients with chronic obstructive pulmonary disease and hypoxemia (PaO2 less than or equal to 55mmHg or oxygen saturation less than or equal to 88% at rest or during exercise). It is contraindicated in patients with peripheral vascular disease because of the potential risk of worsening ischemia in the distal extremities. Cor pulmonale, erythrocythemia, and congestive heart failure are all indications for home oxygen therapy.

Question 16

Disadvantages of using compressed O₂ cylinders in the home include all of the following except:

Accepted Answer

Compressed O2 cylinders do not inherently lead to gas waste when not used, as the gas remains contained within the cylinder until it is released.

Question 17

To determine if a home setting can support the equipment needs of a mechanically ventilated patient being considered for discharge, which of the following would you assess?
I.available space for equipment
II.amperage of power supply
III.number and location of grounded outlets
IV.presence of hazardous appliances

Accepted Answer

I, II, III, and IV are all important factors to assess when determining if a home setting can support the equipment needs of a mechanically ventilated patient. Available space is necessary for the equipment, the amperage of the power supply ensures the equipment can be powered safely, the number and location of grounded outlets are crucial for plugging in the equipment, and the presence of hazardous appliances must be considered to prevent accidents or interference with the equipment's operation.

Question 18

Which of the following would you recommend as the solution used to fill a bubble humidifier used for home O₂ therapy?

Accepted Answer

Distilled water is recommended for use in bubble humidifiers in home O₂ therapy because it does not contain minerals or other impurities that could cause buildup or damage to the equipment. Saline solution may be used in hospital settings or during certain medical procedures, but is not necessary for routine home O₂ therapy. Sterile water and tap water both contain impurities that could potentially harm the patient or equipment.

Question 19

To determine the need for long-term home O₂therapy after initial justification, when should blood gas analysis be repeated?

Accepted Answer

To guide practitioners in providing quality care, the AARC has published a Clinical Practice Guideline on Oxygen Therapy in the Home or Extended Care Facility. Excerpts appear on p. 1291-1292.

Question 20

Physical hazards associated with home O₂therapy equipment include all of the following except:

Accepted Answer

Home oxygen therapy equipment typically uses compressed cylinders of oxygen, which can present a hazard if they are not properly secured or if they leak. It is also important to ensure that all equipment is properly grounded to prevent electrical hazards. Liquid burns can also occur if the equipment is not handled properly. However, gaseous explosions are not a common risk associated with home oxygen therapy equipment.
