The nurse is caring for a client who is experiencing mild shortness of breath during the immediate postoperative period, with oxygen saturation readings between 89% and 91%. What method of oxygen delivery is most appropriate for the client’s needs?
Partial non-rebreathing mask
Simple (Oxy Plus) mask
Nasal cannula
Non-rebreathing mask
The Correct Answer is C
A. Partial non-rebreathing mask:
This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.
B. Simple (Oxy Plus) mask:
The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.
C. Nasal cannula:
Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.
D. Non-rebreathing mask:
The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.

Correct Answer is B
Explanation
A. To ensure long-term prevention of asthma exacerbations:
This statement is not accurate. Prednisone is typically not used for long-term prevention of asthma exacerbations. It is more commonly prescribed for short-term use during acute exacerbations to quickly reduce inflammation and improve symptoms.
B. To gain control of inadequately controlled, persistent asthma:
This is the most accurate explanation. Prednisone is often prescribed to gain control over inadequately controlled, persistent asthma by providing anti-inflammatory effects and helping to manage symptoms during acute episodes.
C. To cure any systemic infection underlying asthma attacks:
Prednisone is not used to cure infections. While it can have anti-inflammatory and immunosuppressive effects, its primary role in asthma is to reduce airway inflammation and control symptoms, not to treat underlying infections.
D. To prevent recurrent pulmonary infections:
Prednisone is not typically prescribed for the prevention of infections. Its use in asthma is more focused on managing inflammation and symptoms during acute exacerbations rather than preventing infections.
Correct Answer is B
Explanation
A. Factor VIII: Factor VIII is a component of the clotting cascade, but it is not the antidote for warfarin. Factor VIII is used in the treatment of hemophilia A.
B. Vitamin K: This is the correct answer. Vitamin K is the antidote for warfarin overdose. It helps in the synthesis of clotting factors.
C. IVIG (Intravenous Immunoglobulin): IVIG is not an antidote for warfarin. It is used for various immune-related conditions.
D. Factor X: Factor X is also a clotting factor, but it is not the antidote for warfarin. Factor Xa inhibitors are used as anticoagulants.
