When addressing a local community group on the topic of obesity, the nurse should include the following points:

Choice A Reason
A blood pressure of 120/80 mmHg is considered within the normal range and is an ideal target for most individuals being treated for hypertension. This finding would not typically alert the nurse to a side effect of lisinopril.

Choice B Reason
Serum potassium of 5.5 mEq/L is higher than the normal range, which is typically between 3.5 and 5.0 mEq/L. Lisinopril can cause hyperkalemia, which is an elevated level of potassium in the blood. This is a known side effect of lisinopril, especially in clients with renal impairment, as it inhibits the renin-angiotensin-aldosterone system and reduces potassium excretion.

Choice C Reason
A heart rate of 80 beats per minute is within the normal range for adults, which is typically 60-100 beats per minute at rest. This finding would not alert the nurse to a side effect of lisinopril.

Choice D Reason
A respiration rate of 16 breaths per minute is within the normal range for adults, which is typically 12-20 breaths per minute at rest. This finding would not alert the nurse to a side effect of lisinopril.

Choice A reason:
Using bronchodilators every 2 hours as needed may not be appropriate for all clients. Bronchodilators are typically used on a schedule or as needed based on symptoms, but overuse can lead to tolerance and decreased effectiveness. The nurse should provide education on the proper use and timing of bronchodilators.

Choice B reason:
Pursed-lip breathing is a technique that helps control shortness of breath and improve ventilation. It can slow down the client's breathing, promote relaxation, and ensure more effective lung function. This technique is particularly beneficial during an acute exacerbation of COPD and should be included in the discharge teaching plan.

Choice C reason:
Increasing home oxygen without proper assessment can be dangerous. Oxygen therapy should be titrated based on the client's oxygen saturation and clinical status. Clients with COPD are at risk of CO2 retention, and too much oxygen can suppress their drive to breathe. The nurse should educate the client on monitoring their SpO2 and when to adjust oxygen levels, typically under the guidance of a healthcare provider.

Choice D reason:
Huff coughing is a technique used to clear mucus from the airways. While it can be effective, it should be taught by a respiratory therapist or nurse who can assess the client's ability to perform the technique correctly. It is not the first-line teaching for a client being discharged with an acute exacerbation of COPD.
