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 D
Explanation
A. The client now has developed a myocardial infarction:
A myocardial infarction (heart attack) is characterized by prolonged ischemia leading to damage or death of heart muscle cells. While the symptoms described could be concerning for a heart attack, the term "myocardial infarction" would typically imply a more sustained and severe ischemic event.
B. The client has developed Prinzmetal's angina:
Prinzmetal's angina, also known as variant angina, is characterized by chest pain that usually occurs at rest and is caused by vasospasm of the coronary arteries. The given scenario does not specifically describe the typical characteristics of Prinzmetal's angina.
C. The client now has stable angina:
Stable angina typically follows a predictable pattern and is relieved with rest and/or nitroglycerin. However, the scenario describes a change in the usual pattern of chest pain.
D. The client now has unstable angina:
Unstable angina is characterized by a change in the usual pattern of stable angina, often occurring at rest or with minimal exertion and not relieved by usual measures. This option seems to align with the information provided.
Correct Answer is D
Explanation
A. Visible clubbing of the fingers and toes
Clubbing is a condition characterized by changes in the shape and appearance of the fingers and toes. It involves enlargement of the fingertips and the nails becoming curved and rounded. Clubbing is not typically associated with peripheral arterial occlusive disease (PAD). It is more commonly seen in conditions such as chronic respiratory or cardiovascular diseases.
B. Unequal peripheral pulses between extremities
Unequal peripheral pulses can be indicative of vascular abnormalities. However, in PAD, the characteristic finding is diminished or absent pulses rather than unequal pulses between extremities. Other conditions, such as arterial embolism or thrombosis, may present with unequal pulses.
C. Reddened extremities with muscle atrophy
Reddened extremities and muscle atrophy are not typical findings in PAD. These symptoms are more characteristic of conditions associated with chronic inflammation or compromised venous circulation, such as chronic venous insufficiency or venous stasis.
D. Loss of hair on the distal extremities
Loss of hair on the distal extremities, particularly on the lower legs and feet, is a common finding in PAD. It results from reduced blood flow and oxygen supply to the hair follicles in the affected areas.
