A nurse is reviewing the laboratory results of a client who has Crohn's disease and experienced an exacerbation 7 days ago. Which of the following laboratory results should the nurse identify as an indication the client is experiencing malnutrition?

A) Weight gain: Weight gain is more commonly associated with right-sided heart failure due to fluid retention and peripheral edema. While left-sided heart failure can lead to overall heart failure, causing weight gain, it is not as specific as breathlessness for left-sided failure.

B) Warm extremities after walking: Warm extremities are generally a sign of good circulation. In clients with left-sided heart failure, reduced cardiac output often leads to poor peripheral circulation, which would more likely cause cool extremities.

C) Breathlessness when carrying an object: Left-sided heart failure leads to decreased cardiac output and pulmonary congestion. As a result, clients often experience breathlessness or dyspnea, especially during physical activities, because the heart cannot efficiently pump blood, leading to fluid buildup in the lungs.

D) Increased urinary output during the day: Left-sided heart failure usually causes decreased renal perfusion, leading to reduced urinary output during the day. Clients might experience nocturia (increased nighttime urination) due to fluid reabsorption when lying down, but increased daytime output is not typical.

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.
