A nurse is reinforcing teaching with a client who is to start taking montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

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. "You should inhale through your nose and exhale through your mouth during purse-lipped breathing."

Pursed-lip breathing is a breathing technique commonly used by individuals with COPD to help improve breathing efficiency and manage dyspnea (shortness of breath). During purse-lip breathing, the individual inhales slowly through the nose and exhales slowly and gently through pursed lips, creating a slight resistance to the airflow. This technique helps to keep the airways open longer during exhalation, reduces air trapping, and improves oxygenation.

B. "Your inspiration should be longer than expiration during purse-lipped breathing."

Pursed-lip breathing typically involves making both the inspiration and expiration longer than usual. The focus is on slowing down the breathing rate and extending the exhalation phase to promote better gas exchange and reduce respiratory effort.

C. "You should cough forcefully during exhalation when you are purse-lipped breathing."

Pursed-lip breathing is a gentle breathing technique used to promote relaxation and control of breathing. Forceful coughing during exhalation is not part of purse-lip breathing and may not be appropriate, especially for individuals with COPD who are prone to airway irritation and bronchospasm.

D. "You should be flat on your back when you perform purse-lipped breathing."

The position for performing purse-lip breathing is not specific to lying flat on the back. Individuals can perform purse-lip breathing in various positions that are comfortable and allow for effective breathing, such as sitting upright or leaning slightly forward. The key is to find a position that facilitates relaxation and optimal lung expansion.
