An adolescent arrives at the emergency department (ED) with a fever and persistent lower right quadrant abdominal pain.

The patient is anxious, fearful, and hyperventilating.

What acid-base imbalance does the nurse anticipate the patient will develop?

Choice A rationale
The absence of coarse crackles is not necessarily an indication that chest physiotherapy (CPT) has been effective for a client with chronic obstructive pulmonary disease (COPD). Coarse crackles are often heard in conditions where there is fluid in the airways, such as pneumonia or heart failure. While their absence might indicate that there is no fluid in the airways, it does not necessarily mean that secretions have been effectively mobilized.
Choice B rationale
An increase in breath sounds is a good indication that chest physiotherapy (CPT) has been effective for a client with COPD3. CPT is a group of therapies designed to improve respiratory efficiency, promote expansion of the lungs, strengthen respiratory muscles, and eliminate secretions from the respiratory system. When these secretions are effectively mobilized and removed, breath sounds can become clearer and more easily heard.
Choice C rationale

The absence of fine crackles is not necessarily an indication that CPT has been effective for a client with COPD. Fine crackles are often heard in conditions where there is fluid in the airways or alveoli, such as pneumonia or heart failure. While their absence might indicate that there is no fluid in the airways or alveoli, it does not necessarily mean that secretions have been effectively mobilized.
Choice D rationale
An increase in respiratory rate is not necessarily an indication that CPT has been effective for a client with COPD. In fact, an increased respiratory rate could indicate respiratory distress, which could suggest that the therapy has not been effective or that the client’s condition has worsened.

Choice A rationale
Ceasing the use of the nasal cannula would interrupt the client’s oxygen therapy, which could potentially worsen their condition. Therefore, this is not the best course of action.
Choice B rationale
Reducing the flow rate to 1 L/minute may not be appropriate as the client’s oxygen needs may not be met at a lower flow rate. The redness under the chin is likely due to the friction from the cannula tubing, not the flow rate of the oxygen.
Choice C rationale
Applying lubricant to the cannula tubing may not be effective in preventing skin breakdown and could potentially cause additional discomfort or complications for the client.
Choice D rationale
Attaching padding around the cannula tubing can help reduce the friction between the tubing and the skin, which can help prevent skin breakdown. This is the most appropriate action to take in this situation.
