Explanation
Answer: d. Non-rebreather mask Explanation
A non-rebreather mask is the most suitable delivery method for a client with severe hypoxemia, as it provides the highest concentration of oxygen (up to 95%) by utilizing a reservoir bag and one-way valves to prevent the rebreathing of exhaled air.
Incorrect choices:
a. Nasal cannula delivers lower concentrations of oxygen and is more appropriate for clients with mild hypoxemia.
b. Simple face mask delivers moderate concentrations of oxygen and is suitable for clients with stable oxygen needs.
c. Venturi mask delivers precise concentrations of oxygen and is commonly used in clients with chronic respiratory conditions.
When administering oxygen therapy, what should the nurse prioritize to ensure the safety of the client?
Explanation
Answer: b. Monitoring oxygen saturation levels Explanation:
Monitoring the client's oxygen saturation levels using a pulse oximeter is crucial to assess the effectiveness of oxygen therapy and ensure the client's oxygen needs are being met adequately.
Incorrect choices:
a. Assessing the client's respiratory rate is important but does not directly measure the adequacy of oxygen therapy.
c. Evaluating the client's level of dyspnea provides subjective information but does not quantify the client's oxygenation status.
d. Adjusting the oxygen flow rate as needed is a valid action, but monitoring oxygen saturation levels is essential to guide the adjustment accurately.
Which intervention should the nurse prioritize to promote effective airway clearance in a client with impaired oxygenation?
Explanation
Answer: c. Encouraging deep breathing and coughing Explanation:
Deep breathing and coughing help to mobilize and clear respiratory secretions, promoting effective airway clearance and improved oxygenation.
Incorrect choices:
a. Incentive spirometry exercises help promote lung expansion but are not directly aimed at airway clearance.
b. Bronchodilator medications are primarily used to alleviate bronchospasm and improve airflow, but they may not directly address airway clearance.
d. Positioning the client in high Fowler's position facilitates lung expansion and may improve oxygenation but does not directly address airway clearance.
A client with chronic obstructive pulmonary disease (COPD) is prescribed long-term oxygen therapy. What is the most important nursing consideration for this client?
Explanation
Answer: b. Monitoring the client's carbon dioxide levels
Explanation: Clients with COPD have a chronic retention of carbon dioxide, so monitoring carbon dioxide levels is essential to prevent the development of respiratory acidosis while providing long-term oxygen therapy.
Incorrect choices:
a. Assessing for signs of oxygen toxicity is important but is not specific to clients with COPD.
c. Proper humidification of oxygen is beneficial but does not take precedence over monitoring carbon dioxide levels in clients with COPD.
d.Ensuring an adequate supply of oxygen is a general consideration for all clients receiving oxygen therapy and is not specific to clients with COPD.
A client is receiving oxygen therapy via a nasal cannula. What is the appropriate flow rate for this client?
Explanation
Answer: b. 4-6 liters per minute
Explanation: The appropriate flow rate for oxygen therapy via a nasal cannula typically ranges from 1-6 liters per minute, with 4-6 liters per minute being a common range to achieve adequate oxygenation.
Incorrect choices:
a. 1-2 liters per minute may be appropriate for clients with mild hypoxemia or during rest.
c. 8-10 liters per minute is generally too high for a nasal cannula and may not be well-tolerated by the client.
d. 12-15 liters per minute is excessively high for a nasal cannula and may be more suitable for a higher flow oxygen delivery system such as a non-rebreather mask or Venturi mask.
