A nurse is providing preoperative teaching to a client who is to undergo a transurethral resection of the prostate to treat benign prostatic hypertrophy. Which of the following client statements should the nurse identify as an understanding of 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) Bounding peripheral pulses: Metabolic acidosis typically does not cause bounding peripheral pulses. In metabolic acidosis, vasodilation might occur, but it usually leads to weaker, not bounding, pulses due to decreased cardiac output and blood pressure.

B) Hyperreflexia: Hyperreflexia is not commonly associated with metabolic acidosis. Instead, metabolic acidosis may cause symptoms like muscle weakness or fatigue due to the effect of acid-base imbalance on neuromuscular function.

C) Cool skin: While cool skin can sometimes be associated with poor perfusion in severe cases, it is not a direct manifestation of metabolic acidosis. Metabolic acidosis more commonly affects internal physiology rather than peripheral skin temperature directly.

D) Hypotension: Hypotension is a common manifestation of metabolic acidosis. The acidosis leads to vasodilation and decreased cardiac contractility, resulting in a drop in blood pressure. This is a critical sign for the nurse to monitor as it indicates the severity of the acid-base imbalance and its effect on the cardiovascular system.
