Question 1:

A nurse is caring for a patient who requires oxygen therapy due to hypoxia. What is the goal of oxygen therapy for this patient?

A. To provide the highest fraction of inspired oxygen (FiO2) possible. B. To use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects. C. To maintain a constant FiO2 regardless of the patient's breathing pattern. D. To deliver a fixed amount of oxygen that is independent of the patient's condition.

Answer and Explanation

Choice A:

The goal of oxygen therapy is not to provide the highest fraction of inspired oxygen (FiO2) possible. This approach can be harmful because excessively high FiO2 levels can lead to oxygen toxicity and other side effects, especially in patients with certain conditions like chronic obstructive pulmonary disease (COPD).

Choice B:

The goal of oxygen therapy is to use the lowest FiO2 that achieves an acceptable blood oxygen level without harmful side effects. This approach is known as titrating the oxygen therapy to the patient's needs and helps prevent potential complications associated with excessive oxygen administration.

Choice C:

Maintaining a constant FiO2 regardless of the patient's breathing pattern is not the goal of oxygen therapy. In some cases, patients may require varying FiO2 levels based on their respiratory status, so it is essential to adjust the oxygen delivery accordingly.

Choice D:

Delivering a fixed amount of oxygen that is independent of the patient's condition is not the goal of oxygen therapy. Oxygen therapy should be individualized and tailored to the patient's specific needs to optimize its effectiveness and safety.

Question 2:

(Select all that apply): A nurse is educating a group of patients about different oxygen delivery devices. Which of the following are examples of low-flow oxygen delivery systems?

A. Nasal cannula. B. Simple face mask. C. Venturi mask. D. Non-rebreather mask.

Answer and Explanation

Choice A:

Nasal cannula is a low-flow oxygen delivery system because the oxygen flow rate is relatively low and the delivered oxygen is mixed with room air before reaching the patient's lungs.

Choice B:

The simple face mask is a low-flow oxygen delivery system. It delivers oxygen at a fixed flow rate and allows room air to mix with the delivered oxygen.

Choice C:

Venturi mask is not a low-flow oxygen delivery system. It is a high-flow system that provides a specific and precise FiO2, making it suitable for patients with chronic respiratory conditions.

Choice D:

The non-rebreather mask is not a low-flow oxygen delivery system. It is a high-flow system that is used when the patient requires a high FiO2, close to 100%, to ensure adequate oxygenation.

Question 3:

A nurse is assessing a patient who has been using a nasal cannula for oxygen therapy. The patient complains of nasal dryness and irritation. What intervention should the nurse implement?

A. Switch to a simple face mask for better oxygen delivery. B. Increase the flow rate of oxygen to improve humidity. C. Assess the patient's nares for patency and skin integrity. D. Reassure the patient that nasal dryness is a normal side effect.

Answer and Explanation

Choice A:

Switching to a simple face mask is not the appropriate intervention for nasal dryness and irritation. A simple face mask covers the nose and mouth, and it may not provide enough relief for nasal dryness as the oxygen flow is still directed towards the nose.

Choice B:

Increasing the flow rate of oxygen will not directly improve humidity. Nasal dryness and irritation are often caused by the lack of moisture in the delivered oxygen. Increasing the flow rate may worsen the issue.

Choice C:

Assessing the patient's nares for patency and skin integrity is the appropriate intervention. Nasal dryness and irritation can be caused by inadequate humidification of the oxygen. Checking the patency of the nares and the condition of the skin can help identify any issues that may be contributing to the discomfort.

Choice D:

Reassuring the patient that nasal dryness is a normal side effect is not sufficient. While nasal dryness can be a common side effect of using a nasal cannula, it is essential to address the issue and provide appropriate interventions to alleviate the discomfort and prevent complications.

Question 4:

A nurse is caring for a patient who is using a partial rebreather mask for oxygen therapy. The patient reports feeling short of breath. What is the nurse's priority action?

A. Increase the flow rate of oxygen to improve oxygenation. B. Assess the mask bag to ensure it remains inflated during inspiration and expiration. C. Switch the patient to a non-rebreather mask for higher oxygen delivery. D. Reassure the patient that shortness of breath is common with this type of mask.

Answer and Explanation

Choice A:

Increasing the flow rate of oxygen may not be the priority action because the patient's shortness of breath could be due to a problem with the mask itself, rather than the amount of oxygen being delivered. Before making any adjustments to the oxygen flow rate, it is essential to assess the equipment's integrity.

Choice B:

This is the priority action because a partial rebreather mask relies on the patient's exhaled breath to partially fill the reservoir bag. If the mask bag does not remain inflated during both inspiration and expiration, the patient may not be receiving the appropriate oxygen concentration, leading to increased shortness of breath. Checking the mask bag ensures that the mask is functioning correctly and delivering the intended oxygen concentration.

Choice C:

Switching the patient to a non-rebreather mask for higher oxygen delivery is not the priority action in this scenario. The non-rebreather mask is used when high oxygen concentrations are required, such as in emergencies or when a patient's condition requires immediate intervention. However, the priority at this moment is to assess the current equipment's effectiveness before considering a change in oxygen delivery method.

Choice D:

Reassuring the patient that shortness of breath is common with this type of mask is not appropriate without first addressing the issue at hand. The nurse should first assess the mask's functionality to ensure it is working correctly and providing the appropriate oxygen concentration before addressing the patient's concerns.

Question 5:

A client with a tracheostomy is receiving oxygen through a tracheostomy collar. What is the advantage of using a tracheostomy collar for oxygen delivery?

A. Provides direct oxygen delivery to the trachea. B. Allows the patient to breathe room air when disconnected from the oxygen source. C. Provides the highest fraction of inspired oxygen (FiO2) among low-flow systems. D. Delivers a fixed amount of oxygen independent of the patient's breathing pattern.

Answer and Explanation

Choice A:

Although a tracheostomy collar provides oxygen directly to the trachea, the advantage specified in the question is related to the ability to breathe room air when disconnected from the oxygen source.

Choice B:

This is the correct answer because a tracheostomy collar has an opening that allows the patient to breathe room air when the oxygen source is disconnected. This feature enables the patient to participate in activities without continuous oxygen delivery, promoting mobility and reducing the feeling of being tethered to an oxygen supply.

Choice C:

A tracheostomy collar does not provide the highest fraction of inspired oxygen (FiO2) among low-flow systems. High-flow systems, such as non-rebreather masks or venturi masks, typically provide the highest FiO2.

Choice D:

A tracheostomy collar does not deliver a fixed amount of oxygen independent of the patient's breathing pattern. Instead, it provides supplemental oxygen in response to the patient's inspiratory effort, which is a characteristic of low-flow oxygen delivery systems.

Question 6:

What is the most appropriate oxygen delivery device for a client with thick secretions, dry mucous membranes, or upper airway edema?

A. Nasal cannula. B. Simple face mask. C. Partial rebreather mask. D. Aerosol mask.

Answer and Explanation

Choice A:

Nasal cannula delivers low to moderate concentrations of oxygen and may not be effective for a client with thick secretions, dry mucous membranes, or upper airway edema. Additionally, the nasal cannula may not provide sufficient humidification to alleviate these conditions.

Choice B:

The simple face mask is not ideal for a client with thick secretions, dry mucous membranes, or upper airway edema as it may not provide enough humidification and could be uncomfortable for the patient.

Choice C:

A partial rebreather mask also may not be the most appropriate choice for this client as it has a reservoir bag that may not adequately humidify the oxygen, leading to discomfort and potential worsening of dry mucous membranes.

Choice D:

The aerosol mask is the most appropriate choice because it delivers humidified oxygen in the form of small aerosol particles, which can help alleviate thick secretions, moisturize dry mucous membranes, and reduce upper airway edema. This mask is beneficial for patients who require higher humidity levels to maintain airway patency and comfort.

Question 7:

Which of the following oxygen delivery devices provides the most precise and consistent fraction of inspired oxygen (FiO2) regardless of the patient's breathing pattern?

A. Nasal cannula. B. Simple face mask. C. Venturi mask. D. Non-rebreather mask.

Answer and Explanation

Choice A:

Nasal cannula delivers oxygen through two small prongs placed in the patient's nostrils. While it is a commonly used and well-tolerated device, the FiO2 delivered can vary significantly depending on the patient's breathing pattern and respiratory rate. Thus, it does not provide the most precise and consistent FiO2.

Choice B:

Simple face masks cover the nose and mouth and can provide higher FiO2 levels compared to nasal cannulas. However, the FiO2 delivered still depends on the patient's breathing pattern and the mask's fit, making it less precise and consistent than other options.

Choice C:

Venturi masks are designed to deliver a specific and accurate FiO2, regardless of the patient's breathing pattern. These masks have adjustable ports to control the mix of air and oxygen, providing precise oxygen concentrations.

Choice D:

Non-rebreather masks have one-way valves and a reservoir bag to deliver higher concentrations of oxygen. Although they can provide high FiO2 levels, the delivered concentration can vary based on the patient's breathing pattern and the mask's fit.

Question 8:

(Select all that apply): A client with a tracheostomy is being weaned from mechanical ventilation. Which of the following oxygen delivery devices can be used for this client?

A. Venturi mask. B. Tracheostomy collar. C. T-piece. D. Aerosol mask. E. Mechanical ventilator.

Answer and Explanation

Choice A:

Venturi masks are not typically used with tracheostomy patients, as they are more suitable for patients with intact upper airways.

Choice B:

Tracheostomy collars are specifically designed for patients with tracheostomies. They provide oxygen directly to the tracheostomy tube, making them appropriate for weaning tracheostomized patients from mechanical ventilation.

Choice C:

T-piece adapters are commonly used for patients with tracheostomies to deliver oxygen. They are simple devices that deliver oxygen directly to the tracheostomy tube.

Choice D:

Aerosol masks are not specifically designed for tracheostomy patients and may not provide adequate oxygen delivery for them.

Choice E:

Mechanical ventilators are not an oxygen delivery device; instead, they are used to provide mechanical ventilation support to the patient and can incorporate various oxygen delivery systems.

Question 9:

A nurse is caring for a client who has hypoxemia and is receiving oxygen therapy via nasal cannula at 4 L/min. The nurse should monitor the client for which of the following complications of oxygen therapy?

A. Oxygen toxicity. B. Carbon dioxide retention. C. Nasal dryness. D. Fire hazard.

Answer and Explanation

Choice A:

At a flow rate of 4 L/min, oxygen therapy through a nasal cannula can increase the risk of oxygen toxicity, especially if used for prolonged periods. Oxygen toxicity can cause damage to the lungs and other organs.

Choice B:

Carbon dioxide retention is not a common complication at this flow rate. It may occur in patients with severe chronic obstructive pulmonary disease (COPD) at higher oxygen flow rates.

Choice C:

Nasal dryness is a common but relatively minor complication of oxygen therapy via nasal cannula. It can cause discomfort but is not a severe concern.

Choice D:

Fire hazard is not directly related to the use of a nasal cannula but rather to the use of oxygen in the presence of flammable materials or near open flames. It is a concern for all oxygen delivery devices, not specific to nasal cannulas.

Question 10:

(Select all that apply) A nurse is preparing to administer oxygen therapy to a client who has COPD and requires a precise concentration of oxygen. Which of the following devices should the nurse use for this client?

A. Venturi mask. B. Non-rebreather mask. C. Aerosol mask. D. Simple face mask. E. Tracheostomy collar.

Answer and Explanation

Choice A:

A Venturi mask is designed to deliver a precise concentration of oxygen and is often used in COPD, where it is important not to over-oxygenate the patient. It allows for the adjustment of oxygen concentration by changing the color-coded entrainment adapters.

Choice B:

A non-rebreather mask is not typically used for clients who require a precise concentration of oxygen because it is designed to deliver high concentrations of oxygen, but without a way to precisely control the amount.

Choice C:

An aerosol mask can be used with a nebulizer system to deliver specific concentrations of oxygen along with medication, which is beneficial for COPD patients who may need bronchodilators or steroids in addition to oxygen therapy.

Choice D:

A simple face mask is not suitable for delivering a precise concentration of oxygen as it does not allow for the fine control needed for COPD patients. It is generally used for short-term oxygen therapy and for patients who require a moderate amount of oxygen.

Choice E:

A tracheostomy collar can provide a specific concentration of oxygen when used with a tracheostomized patient and is suitable for long-term use in COPD patients who have a tracheostomy.

Question 11:

A nurse is teaching a client who is going home on continuous liquid oxygen therapy. The client asks the nurse, "How do I know when to refill the oxygen tank?”. Which of the following responses should the nurse give?

A. "You should refill the tank when it feels light and empty.”. B. "You should refill the tank when the pressure gauge reads below 500 psi.”. C. "You should refill the tank when you hear a hissing sound from the valve.”. D. "You should refill the tank when an alarm sounds from the regulator.".

Answer and Explanation

Choice A:

Refilling the oxygen tank based on the client's perception of it feeling light and empty is not a reliable method, as it may lead to running out of oxygen unexpectedly.

Choice B:

The nurse should instruct the client to refill the oxygen tank when the pressure gauge reads below 500 psi. This is a standardized method to ensure the client does not run out of oxygen, as the pressure gauge provides an accurate measure of the remaining oxygen in the tank.

Choice C:

Refilling the tank when a hissing sound is heard from the valve is not a valid method for determining the need for a refill and may result in running out of oxygen.

Choice D:

Waiting for an alarm sound from the regulator to refill the tank is not recommended, as the tank could run out of oxygen before the alarm activates.

Question 12:

A nurse is caring for a client who is dyspneic and slightly cyanotic, with a respiratory rate of 28/min. The nurse determines that the client has impaired gas exchange during which of the following phases of the nursing process?

A. Assessment. B. Diagnosis. C. Planning. D. Evaluation.

Answer and Explanation

Choice A:

Assessment is the first phase of the nursing process where the nurse collects comprehensive data pertinent to the patient’s health or the situation. In the scenario, the nurse has already gathered data about the client’s respiratory status, indicating that the assessment phase has been completed.

Choice B:

Diagnosis is the phase where the nurse analyzes the assessment data to determine the issues, which in this case is ‘impaired gas exchange.’ This is the phase where the nurse identifies that the client’s symptoms (dyspnea and cyanosis) and elevated respiratory rate are indicative of impaired gas exchange.

Choice C:

Planning is the phase where the nurse develops a plan that prescribes strategies and alternatives to attain expected outcomes. It follows the diagnosis and involves setting priorities, but in the given scenario, the nurse is still at the stage of identifying the problem rather than planning interventions.

Choice D:

Evaluation is the final phase of the nursing process where the nurse assesses the client’s response to the nursing actions and plan’s effectiveness towards achieving the health care goals. Since the nurse is determining the issue, not evaluating the client’s response to interventions, this phase is not the correct answer.

Question 13:

A nurse is caring for a client who has been receiving oxygen via simple face mask for 6 hours. Which of the following assessment findings indicates that oxygen therapy has been effective?

A. PaO2 80 mmHg. B. SaO2 88%. C. RR 32/min. D. BP 160/90 mmHg.

Answer and Explanation

Choice A:

PaO2 (partial pressure of oxygen in arterial blood) of 80 mmHg indicates that the oxygen therapy has been effective. Normal PaO2 levels range from 75 to 100 mmHg, so a value of 80 mmHg suggests adequate oxygenation.

Choice B:

SaO2 (arterial oxygen saturation) of 88% is below the normal range (typically 95-100%) and indicates hypoxemia, suggesting that the oxygen therapy has not been fully effective.

Choice C:

A respiratory rate (RR) of 32 breaths per minute is significantly higher than the normal range (12-20 breaths per minute) and indicates respiratory distress, suggesting that the oxygen therapy has not been effective.

Choice D:

Blood pressure (BP) of 160/90 mmHg is elevated and indicates hypertension, which is not a direct measure of the effectiveness of oxygen therapy. This finding does not provide information about the patient’s oxygenation status.

Question 14:

A nurse is caring for a patient who has a tracheostomy and is receiving oxygen therapy via tracheostomy collar at 40% FiO2. The nurse should ensure that which of the following is in place to prevent complications?

A. A humidifier. B. A water seal. C. A suction catheter. D. A chest tube.

Answer and Explanation

Choice A:

A humidifier is necessary to prevent complications in a patient receiving oxygen therapy via a tracheostomy collar. Oxygen delivered through a tracheostomy can dry out the airways and cause discomfort and potential complications. Adding humidity helps maintain airway moisture and prevents drying of the mucous membranes, reducing the risk of mucus plugs and irritation.

Choice B:

A water seal is not necessary for a patient receiving oxygen therapy via a tracheostomy collar. Water seals are used in chest drainage systems to prevent air from entering the pleural space, but they are not relevant in this scenario.

Choice C:

A suction catheter is used to clear secretions from the airway but is not directly related to preventing complications with oxygen therapy via a tracheostomy collar.

Choice D:

A chest tube is not needed for a patient receiving oxygen therapy via a tracheostomy collar. Chest tubes are inserted to drain fluid or air from the pleural space, which is not applicable to this situation.

Question 15:

A nurse is caring for a patient who is receiving oxygen therapy via partial rebreather mask at 10 L/min. The nurse should instruct the patient to do which of the following to ensure effective oxygen delivery?

A. Keep the reservoir bag fully inflated at all times. B. Breathe through the mouth and exhale through the nose. C. Adjust the elastic strap to fit snugly around the face. D. Remove the mask every 15 minutes to check the skin.

Answer and Explanation

Choice A:

In a partial rebreather mask, the reservoir bag should be kept fully inflated at all times to ensure the delivery of the highest possible oxygen concentration during inspiration. The bag collects oxygen during expiration, and the one-way valve prevents the exhaled gases from entering the bag. This way, the patient can inhale a mixture of oxygen from the reservoir and fresh oxygen flow.

Choice B:

Breathing through the mouth and exhaling through the nose is not a necessary instruction for a patient using a partial rebreather mask. It doesn't directly impact the effectiveness of oxygen delivery.

Choice C:

Adjusting the elastic strap to fit snugly around the face is not specific to ensuring effective oxygen delivery. It is a general guideline for mask fitting but doesn't directly affect oxygen administration.

Choice D:

Removing the mask every 15 minutes to check the skin is not necessary and can disrupt the delivery of oxygen therapy. It's essential to maintain a consistent oxygen supply to the patient's lungs, and removing the mask frequently can compromise that. Checking the skin can be done periodically without removing the mask completely.

Question 16:

A nurse is caring for a patient who is receiving oxygen therapy via non-rebreather mask at 15 L/min. The nurse should recognize that this device has which of the following advantages?(Select all that apply)

A. It delivers the highest concentration of oxygen among low-flow systems. B. It prevents the patient from rebreathing exhaled air. C. It provides consistent and precise oxygen delivery. D. It allows room air to enter through exhalation ports. E. It minimizes the risk of carbon dioxide retention.

Answer and Explanation

Choice A:

A non-rebreather mask is designed to deliver a high concentration of oxygen, often deemed the highest among low-flow systems. It achieves this through a reservoir bag that is filled with pure oxygen, which the patient breathes in without the dilution of room air.

Choice B:

This mask has one-way valves that prevent the patient from rebreathing exhaled carbon dioxide. The exhaled air exits through side ports, ensuring that only oxygen from the reservoir is inhaled.

Choice C:

While a non-rebreather mask delivers a high concentration of oxygen, it does not provide a consistent and precise oxygen delivery compared to devices like a Venturi mask, which are designed to deliver a specific and constant oxygen concentration.

Choice D:

The design of a non-rebreather mask does not allow room air to enter through the exhalation ports. The one-way valves are there to ensure that exhaled air does not enter the reservoir bag and that room air does not mix with the oxygen being inhaled.

Choice E:

By delivering a high concentration of oxygen and preventing the rebreathing of exhaled gases, a non-rebreather mask minimizes the risk of carbon dioxide retention, which can be a concern with other oxygen delivery systems that allow for the rebreathing of a portion of exhaled air.

Question 17:

A nurse is caring for a patient who is receiving oxygen therapy via nasal cannula. The nurse notices that the patient's nares are dry and irritated. What should the nurse do first?

A. Apply petroleum jelly to the nares. B. Increase the flow rate of oxygen. C. Change the nasal cannula to a face mask. D. Connect the device to a humidifier.

Answer and Explanation

Choice A:

Applying petroleum jelly to the nares is not the first action to take. It might provide temporary relief, but it is essential to address the root cause of dryness, which is the lack of moisture in the oxygen delivered.

Choice B:

Increasing the flow rate of oxygen is not the first step because it may not address the dryness issue. It can lead to a higher concentration of oxygen, but it won't solve the problem of dry and irritated nares.

Choice C:

Changing the nasal cannula to a face mask is not necessary to address the dryness. Face masks may not be well-tolerated by some patients, and it's better to try less invasive interventions first.

Choice D:

The nurse should connect the nasal cannula to a humidifier first. Dry and irritated nares are common side effects of oxygen therapy via nasal cannula, and using a humidifier adds moisture to the oxygen, reducing irritation and discomfort for the patient.

Question 18:

A nurse is teaching a patient who has a prescription for home oxygen therapy. Which of the following instructions should the nurse include? (Select all that apply.).

A. Avoid smoking or being near open flames while using oxygen. B. Use cotton or wool clothing and bedding while using oxygen. C. Check the position of the oxygen delivery device frequently. D. Report any signs of hypoxia or hypercarbia to the provider. E. Adjust the flow rate of oxygen as needed.

Answer and Explanation

Choice A:

The nurse should instruct the patient to avoid smoking or being near open flames while using oxygen. Oxygen supports combustion, and smoking or exposure to flames can lead to a fire hazard.

Choice B:

Using cotton or wool clothing and bedding is not a recommended instruction for oxygen therapy. Synthetic materials are preferred as they are less likely to catch fire compared to cotton or wool.

Choice C:

Checking the position of the oxygen delivery device frequently is important to ensure proper oxygen delivery and avoid any displacement or obstruction that may compromise the therapy's effectiveness.

Choice D:

Instructing the patient to report any signs of hypoxia (low oxygen levels) or hypercarbia (high carbon dioxide levels) to the provider is crucial for early detection of potential complications and appropriate management.

Choice E:

Instructing the patient to adjust the flow rate of oxygen as needed allows them to respond to varying oxygen requirements, especially during activities or changes in their respiratory condition.

Question 19:

A nurse is assessing a patient who is receiving oxygen therapy via venturi mask. The nurse hears a hissing sound from the mask and observes that the patient's skin color is pale. What should the nurse say to the patient?

A. "I'm going to check your oxygen level with this device on your finger.”. B. "You need to breathe more deeply and slowly to get enough oxygen.”. C. "There is a problem with your mask and I need to fix it right away.”. D. "You are getting too much oxygen and I need to lower the flow rate.".

Answer and Explanation

Choice A:

The nurse should not immediately check the patient's oxygen level with a finger device because the priority is to address the hissing sound from the mask and the patient's pale skin color, which could indicate inadequate oxygen delivery.

Choice B:

Instructing the patient to breathe more deeply and slowly won't address the issue of the hissing sound and the possible oxygen delivery problem. The nurse should address the equipment issue first.

Choice C:

This is the correct choice. The nurse should inform the patient that there is a problem with the mask, and it needs to be fixed promptly to ensure adequate oxygen therapy.

Choice D:

Lowering the flow rate may not be appropriate until the nurse has assessed and resolved the problem with the mask. It's essential to troubleshoot the equipment first.

Question 20:

A nurse is evaluating the effectiveness of oxygen therapy for a patient who has COPD. The nurse notes that the patient's PaO2 is 65 mmHg and SaO2 is 88%. What should the nurse say to the patient?

A. "Your oxygen levels are within the normal range for your condition.”. B. "Your oxygen levels are too low and you need more oxygen.”. C. "Your oxygen levels are too high and you need less oxygen.”. D. "Your oxygen levels are not affected by your oxygen therapy.".

Answer and Explanation

Choice A:

The patient's PaO2 is 65 mmHg and SaO2 is 88%. PaO2 values below 80 mmHg and SaO2 below 90% are considered below normal ranges. Therefore, the patient's oxygen levels are not within the normal range for the condition.

Choice B:

This is the correct choice. The patient's PaO2 and SaO2 levels indicate that they are not receiving enough oxygen, and additional oxygen therapy is needed.

Choice C:

The patient's oxygen levels are low, not high. Providing less oxygen would worsen the situation.

Choice D:

The patient's oxygen levels are affected by oxygen therapy, as they indicate that the current therapy is insufficient. Additional interventions are needed to improve oxygenation.
