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?

A. Intermittent claudication:

Intermittent claudication is more commonly associated with peripheral arterial insufficiency rather than venous insufficiency. It is caused by inadequate blood flow to the muscles during activity, resulting in cramping or pain that typically resolves with rest.

B. Brownish discoloration to the legs:

Brownish discoloration to the legs, often referred to as hemosiderin staining, is a common finding in peripheral venous insufficiency. It occurs due to the breakdown of red blood cells and the deposition of hemosiderin in the tissues, especially around the ankles.

C. Weak or absent pedal pulses:

Weak or absent pedal pulses are more indicative of peripheral arterial insufficiency rather than venous insufficiency. Peripheral arterial disease can result in decreased blood flow to the extremities, leading to diminished pulses.

D. Unequal peripheral pulses between extremities:

Unequal peripheral pulses between extremities are also more suggestive of arterial insufficiency. Conditions such as atherosclerosis or arterial embolism can cause variations in pulses between different limbs.

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.
