A nurse is collecting data for a client who has COPD. The nurse should expect the client's chest to be which of the following shapes?

A. Constipation

Constipation is not typically associated with obstructive sleep apnea. However, sleep disturbances and certain medications used to manage OSA may indirectly contribute to constipation in some cases.

B. Nausea

Nausea is not a common symptom of obstructive sleep apnea. While sleep disturbances may affect gastrointestinal function in some individuals, nausea is not a typical manifestation of OSA.

C. Headache

One of the common findings associated with obstructive sleep apnea (OSA) is headache. This occurs due to the repeated episodes of apnea (cessation of breathing) during sleep, which leads to intermittent hypoxia (low oxygen levels) and subsequent cerebral vasodilation. The vasodilation can trigger headaches, often described as morning headaches, upon waking up. These headaches are typically frontal and may be accompanied by other symptoms such as fatigue and irritability.

D. Hypotension

Hypotension (low blood pressure) is not a typical finding in obstructive sleep apnea. In fact, individuals with OSA are more likely to have hypertension (high blood pressure) due to the effects of repeated apnea episodes on the cardiovascular system, such as increased sympathetic activity and arterial stiffness.

A. Rest in a supine position.

This option is not recommended for improving gas exchange in emphysema. Resting in a supine position can lead to decreased lung expansion and increased dyspnea in individuals with emphysema. Optimal lung expansion is crucial for efficient gas exchange, and certain positions, such as sitting upright or using pillows to support the head and chest, are preferred to facilitate breathing.

B. Consume a low-protein diet.

A low-protein diet is not directly related to improving gas exchange in emphysema. In fact, adequate protein intake is important for maintaining overall health and supporting respiratory muscle function. Protein is necessary for tissue repair and maintaining muscle strength, including the respiratory muscles. Therefore, a balanced diet that includes adequate protein intake is recommended for individuals with emphysema.

C. Breathe in through her nose and out through pursed lips.

This is the correct choice. Breathing in through the nose and out through pursed lips helps to create positive pressure in the airways during exhalation. This positive pressure helps to keep the airways open, prevents premature collapse of the air sacs (alveoli), and facilitates more effective gas exchange. It also slows down the rate of breathing, reduces the work of breathing, and can alleviate shortness of breath (dyspnea) in individuals with emphysema.

D. Limit fluid intake throughout the day.

Limiting fluid intake throughout the day is not recommended for improving gas exchange in emphysema. Adequate hydration is important for thinning respiratory secretions, which can make it easier to clear mucus from the airways. Dehydration can worsen respiratory symptoms and increase the risk of complications. Therefore, maintaining adequate fluid intake is essential for individuals with emphysema.
