A community health nurse teaches a group of seniors at an assisted living facility about modifiable risk factors that contribute to the development of peripheral arterial disease (PAD). The nurse knows that the teaching was effective based on which of the following statements?

A. The development of chronic obstructive pulmonary disease (COPD)

Explanation: The signs and symptoms described, including crackles, orthopnea, S3 heart sound, cough with pink, frothy sputum, and low pulse oximetry, are more indicative of heart failure than COPD.

B. The development of left-sided heart failure

Explanation: This is the correct answer. The signs and symptoms, such as crackles, orthopnea, and cough with pink, frothy sputum, are characteristic of left-sided heart failure. The S3 heart sound is often associated with increased ventricular filling pressures.

C. The development of right-sided heart failure

Explanation: The presented signs and symptoms are more consistent with left-sided heart failure. Right-sided heart failure is often associated with peripheral edema, hepatomegaly, and jugular venous distension.

D. The development of cor pulmonale

Explanation: Cor pulmonale is typically associated with right-sided heart failure due to chronic lung disease. The signs and symptoms described are more indicative of left-sided heart failure.

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.
