A nurse is providing discharge teaching to a female client who has the communicable disease herpes simplex virus II. Which of the following instructions should the nurse include in the teaching?

A) Instruct the client to perform coughing exercises after meals.
Coughing exercises after meals can help clear the airways of mucus, which is beneficial for clients with COPD. Effective airway clearance is crucial to improve breathing and reduce the risk of infections. This intervention can enhance respiratory function and comfort.

B) Limit the client's fluid intake to 1,500 mL/day.
Limiting fluid intake is generally not recommended for clients with COPD unless there is a specific medical reason, such as heart failure. Adequate hydration helps keep mucus thin and easier to expectorate, which is important for respiratory health.

C) Encourage the client to sit in a chair for 1 hr several times per day.
Encouraging the client to sit in a chair helps promote mobility and prevent complications associated with prolonged bed rest. However, while sitting up can improve lung expansion, it is not the most specific or direct intervention to address dyspneic episodes.

D) Initiate oxygen therapy for the client via nasal cannula at 10 L/min.
Administering oxygen at a high flow rate like 10 L/min is not typically appropriate for clients with COPD due to the risk of depressing their respiratory drive. Oxygen therapy should be carefully titrated and monitored based on the client's needs and blood gas levels.

A) Decreased deep-tendon reflexes: Decreased deep-tendon reflexes can indicate hyperkalemia, which occurs when potassium levels are too high. This is not a sign of effective potassium chloride supplementation for hypokalemia, as it suggests an imbalance in the opposite direction.

B) Regular heart rhythm: A regular heart rhythm is a key indicator that potassium levels are within the normal range. Potassium is crucial for proper cardiac function, and maintaining an adequate level helps prevent arrhythmias and supports effective heart rhythms.

C) Hypoactive bowel sounds: Hypoactive bowel sounds can be associated with various conditions, including electrolyte imbalances like hypokalemia. However, the presence of hypoactive bowel sounds does not directly indicate that potassium chloride supplementation is effective.

D) Respiratory rate 10/min: A respiratory rate of 10/min is below the normal range and can be a sign of respiratory depression or other issues. This finding does not relate to the effectiveness of potassium chloride supplements in treating hypokalemia.
