A nurse caring for a client who has an infected wound removes a dressing saturated with blood and purulent drainage. How should the nurse dispose of the dressing material?

Choice A rationale:

This choice is not correct because verifying the oxygen flow rate every other day is not part of the discharge teaching for a client on home oxygen therapy. The flow rate should be checked regularly, not just every other day, to ensure the client's safety and well-being.

Choice B rationale:

This choice is correct. Checking the tops of the ears for skin breakdown is important in a client using a nasal cannula for oxygen therapy. Prolonged use of the cannula can lead to irritation and pressure-related skin breakdown behind the ears.

Choice C rationale:

This choice is correct. Posting "no smoking signs in a prominent location in the home" is an important safety measure for a client on oxygen therapy. Oxygen supports combustion, and smoking in the presence of oxygen can lead to fire hazards.

Choice D rationale:

This choice is correct. Checking the cannula position on a regular basis is essential to ensure that the oxygen is being delivered effectively and that the client is not experiencing discomfort or skin breakdown due to improper positioning.

Choice E rationale:

This choice is correct. Applying petroleum ointment to the nares if they become dry and irritated is a suitable intervention to maintain the client's comfort and prevent skin irritation from the cannula.

The correct answer is choice B. Increased anteroposterior diameter of the chest.

Choice A rationale:

Petechiae on the chest (Choice A) are tiny red or purple spots that appear on the skin due to small blood vessel breakage. They are not typically associated with COPD and emphysema. Petechiae are more often related to conditions like thrombocytopenia or certain infections, where blood clotting is impaired.

Choice B rationale:

Increased anteroposterior diameter of the chest, often referred to as "barrel chest," is a characteristic finding in clients with COPD and emphysema. This occurs due to the hyperinflation of the lungs and the loss of elasticity in the lung tissues, which causes the chest to become rounded and the ribs to be positioned more horizontally.

Choice C rationale:

An oxygen saturation level of 96% (Choice C) is within the normal range for oxygen saturation. However, while it's important for clients with COPD to maintain adequate oxygen levels, this value doesn't specifically correlate with the client's symptoms of a wet cough and occasional shortness of breath.

Choice D rationale:

Respiratory alkalosis (Choice D) involves an increase in blood pH due to decreased levels of carbon dioxide (hypocapnia) caused by hyperventilation. While respiratory alkalosis can occur in clients with COPD due to compensatory hyperventilation, it is not a direct assessment finding related to the client's symptoms of a wet cough and occasional shortness of breath.
