A nurse formulates the problem of ineffective airway clearance for a client who has pneumonia. Which assessment data best supports this problem?
Respiratory rate of 24/min.
Weak, nonproductive cough.
Pulse oximetry (SpO2) of 90%.
Shortness of breath with activity.
The Correct Answer is B
Choice A reason:
A respiratory rate of 24/min is slightly elevated, which can be expected in a client with pneumonia due to the body's attempt to increase oxygen intake and carbon dioxide elimination. However, this rate does not directly indicate ineffective airway clearance.
Choice B reason:
A weak, nonproductive cough is a key indicator of ineffective airway clearance. In pneumonia, the presence of secretions in the airways is common, and an effective cough is necessary to clear these secretions. A weak cough that does not produce sputum suggests that the client is unable to clear their airways effectively, which can lead to impaired gas exchange and worsening of symptoms.
Choice C reason:
Pulse oximetry (SpO2) of 90% indicates that the client's oxygen saturation is below the normal range, which is typically between 95-100% for healthy individuals. While this finding is concerning and warrants intervention, it is a result of ineffective airway clearance rather than a direct indicator of it.
Choice D reason:
Shortness of breath with activity is common in clients with pneumonia and can result from various factors, including impaired gas exchange, decreased lung compliance, and increased work of breathing. While it may be associated with ineffective airway clearance, it is not as specific as a weak, nonproductive cough for indicating this particular problem.

Correct Answer is D
Explanation
Choice A Reason
Applying cool compresses to the affected limb can help reduce swelling and provide pain relief. However, it's important to follow the surgeon's specific postoperative orders, as the application of cold can vary depending on the surgical technique and patient's condition.
Choice B Reason
Placing a soft pillow under the knee is not recommended after total knee replacement surgery. This position can lead to decreased range of motion and contractures. The knee should be kept in a more extended position to promote healing and mobility.
Choice C Reason
Promoting bedrest for an extended period is not typically advised following knee replacement surgery. Early mobilization is important to prevent complications such as deep vein thrombosis and to encourage circulation and healing. The duration of bedrest should be as per the surgeon's protocol.
Choice D Reason
Encouraging increased fluid intake is important after surgery to prevent dehydration, promote kidney function, and ensure adequate blood volume and circulation. Proper hydration is essential for healing and can help with the metabolism of medications used during and after surgery.
Correct Answer is C
Explanation
Choice A Reason
While hypertension can contribute to the development of PAD, it does not directly cause fats to deposit in the arteries. Hypertension can damage the arterial walls, making them more susceptible to atherosclerosis, but it is not the primary mechanism of PAD development.
Choice B Reason
Excess fats in the diet can contribute to atherosclerosis, which is the accumulation of plaques in the arterial walls. However, the fats do not simply get stored; they combine with other substances, including calcium and inflammatory cells, to form plaques that can restrict blood flow.
Choice C Reason
This statement is the most accurate. PAD is primarily caused by atherosclerosis, which is the buildup of plaques formed by fats, cholesterol, calcium, and other substances in the blood. These plaques can harden and narrow the arteries, leading to reduced blood flow to the extremities. The process can be exacerbated by factors such as smoking, diabetes, and high cholesterol.
Arterial spasms can occur, but they are not the typical cause of chronic PAD. Spasms are more often associated with conditions like Raynaud's phenomenon or can be a response to stress or cold temperatures. PAD is usually a result of progressive atherosclerosis rather than intermittent spasms.
