Question 1

The client is started on 90% oxygen by nonrebreather mask at 0800.The nurse working the night shift assesses the client,who complains of substernal pain and dyspnea and has rales audible in the lower lung field bilaterally.Based on these assessment findings,what does the nurse suspect?

A)Myocardial hypoxia
B)Pulmonary emboli
C)Oxygen toxicity
D)Congestive heart failure

Oxygen toxicity

Accepted Answer

The symptoms of substernal pain, dyspnea, and rales in the lungs after being on high concentrations of oxygen suggest oxygen toxicity.

Question 2

The nurse is caring for a 31-week premature infant requiring oxygen therapy after delivery.Which would be the most effective means of delivering oxygen?&#10;A)Partial rebreather mask&#10;B)Nonrebreather mask&#10;C)Face mask&#10;D)Oxygen hood&#10;

Accepted Answer

An oxygen hood is the most effective means of delivering oxygen to a premature infant. It provides a high concentration of oxygen while allowing for easy monitoring of the infant's respiratory status. Masks may not fit well on premature infants, and the flow of oxygen from a mask may not be adequate for their needs.

Question 3

When administering oxygen,which step would the nurse perform first?&#10;A)Place the mask,cannula,or tent on the client.&#10;B)Regulate the flow of oxygen.&#10;C)Pad the nasal cannula behind the client's ears.&#10;D)Fit the nose bracket on the mask to the contour of the client's face.&#10;

Accepted Answer

The nurse would first regulate the flow of oxygen to ensure that the client is receiving the appropriate amount of oxygen. Only after this is done should the nurse place the mask, cannula, or tent on the client, pad the nasal cannula behind the client's ears, or fit the nose bracket on the mask to the contour of the client's face.

Question 4

Which direction would be incorrect for the nurse to teach the client when describing the process of measuring peak expiratory flow?&#10;A)&#34;Sit upright,with the back and chest free from contact with the bed or chair.&#34;&#10;B)&#34;Reset the marker on the flow meter to zero before beginning.&#34;&#10;C)&#34;Create a tight seal around the mouthpiece with the lips.&#34;&#10;D)&#34;Exhale slowly and deeply.&#34;&#10;

Accepted Answer

The correct direction is to instruct the client to exhale quickly and forcefully into the peak flow meter to obtain an accurate reading. Exhaling slowly and deeply can result in an inaccurate measurement of the peak expiratory flow rate. Choices A, B, and C are all correct directions for measuring peak expiratory flow.

Question 5

The client is being prepared for home oxygen use.The client's spouse smokes two to three packs of cigarettes per day.Which is the nurse's priority instruction to the client and spouse?&#10;A)Inform the health care provider that home oxygen use would be dangerous for this client.&#10;B)Instruct the spouse on the need to smoke outside.&#10;C)Instruct the spouse on the hazards of smoking in the same room with the client.&#10;D)Instruct the spouse to quit smoking.&#10;

Accepted Answer

Smoking in the same room with the client can cause a fire or explosion.

Question 6

The nurse is participating in an interdisciplinary meeting for a client who requires the use of oxygen.When choosing the oxygen delivery system for the client,which items must the group take into consideration?

A)Respiratory needs
B)Comfort
C)Stage of development
D)Heart rate
E)Tidal volume

Accepted Answer

The answer of The nurse is participating in an interdisciplinary...

Question 7

The nurse would consider which action by unlicensed assistive personnel (UAP)as appropriate when observing care that is provided?&#10;A)Increasing the oxygen flow rate when low oxygen saturation is measured on the client&#10;B)Initiating oxygen therapy when a client is found to be dyspneic&#10;C)Changing the oxygen delivery from nasal cannula to face mask when the client complains of nasal discomfort&#10;D)Measuring oxygen saturation and replacing the client's oxygen mask when it becomes malpositioned while the client sleeps&#10;

Accepted Answer

UAP can measure oxygen saturation and replace a malpositioned oxygen mask under the supervision and direction of a licensed nurse, but should not make changes to the oxygen delivery method, initiate oxygen therapy, or adjust oxygen flow rates as these actions require specialized training and expertise.

Question 8

When caring for a client receiving oxygen therapy,which is not a priority documentation for the nurse to complete?&#10;A)Percentage of oxygen or flow of oxygen delivered&#10;B)Method of delivering oxygen&#10;C)Respiratory status,including respiratory rate,oxygen saturation,and respiratory assessment&#10;D)Cardiorespiratory monitoring data&#10;

Accepted Answer

Cardiorespiratory monitoring data is important information to document, but it is not the top priority when caring for a client receiving oxygen therapy. The priority documentation includes the percentage or flow of oxygen delivered, the method of delivering oxygen, and the client's respiratory status and assessment.

Question 9

The nurse is caring for a client requiring noninvasive continuous positive pressure ventilation for obstructive sleep apnea.Which less invasive treatments to reduce sleep apnea would the nurse explore prior to initiating this intervention?

A)Surgery to remove the uvula
B)Community support groups
C)Oral appliances to advance the lower jaw and base of the tongue
D)Weight loss
E)Medications

Accepted Answer

Noninvasive continuous positive pressure ventilation (CPAP) is a highly effective treatment for sleep apnea, but it is also invasive and requires daily compliance with wearing a mask. Before initiating CPAP, less invasive treatment options should be explored. Surgery to remove the uvula is rarely performed as there are more effective and less invasive options available. Community support groups may be beneficial for some clients, but they do not directly address the physical cause of sleep apnea. Medications are not typically effective for treating sleep apnea. Oral appliances to advance the lower jaw and base of the tongue and weight loss are effective noninvasive treatments for obstructive sleep apnea and should be considered before initiating CPAP.

Question 10

The client,newly prescribed continuous positive pressure ventilation,complains that the forced air is bothersome.Which interventions could the nurse recommend to reduce the client's discomfort?&#10;A)Ramping over 15 minutes&#10;B)Using heated humidification&#10;C)Reducing the pressure&#10;D)Increasing the oxygen concentration&#10;E)Changing the client's position&#10;

Accepted Answer

Ramping over 15 minutes gradually increases the pressure, allowing the client to adjust more comfortably. Using heated humidification can alleviate dryness and discomfort caused by the forced air.

Question 11

The nurse needs to deliver the highest concentration of oxygen (95% to 100%).Which type of oxygen delivery device would the nurse choose?&#10;A)Face mask&#10;B)Nasal cannula&#10;C)Partial rebreather mask&#10;D)Nonrebreather mask&#10;

Accepted Answer

The answer of The nurse needs to deliver the highest...
