A nurse is evaluating teaching on a client who has a new prescription for montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.

Repositioning the client is the appropriate action for the nurse to take, as chest burning may indicate that the chest tube is kinked, twisted, or compressed, which can impair drainage and ventilation. The nurse should gently move the client to a different position and check that the chest tube is not bent or occluded by clothing, bedding, or furniture. The nurse should also ensure that there are no dependent loops or coils in the tubing and that it is secured to prevent dislodgment.

a) Increasing the client's wall suction is not advisable, as it can cause increased negative pressure in the pleural space and lead to tension pneumothorax. Increasing the wall suction does not affect the patency of the chest tube or the drainage of air or fluid from the lung. The nurse should maintain the wall suction at the prescribed level and monitor for any changes in the suction chamber.
c) Clamping the client's chest tube is not advisable, as it can cause air or fluid accumulation in the pleural space and lead to tension pneumothorax. Clamping the chest tube does not relieve chest burning or improve drainage or ventilation. The nurse should only clamp the chest tube for a brief period of time and under specific circumstances, such as changing the drainage system, assessing for an air leak, or preparing for chest tube removal.
d) Stripping the client's chest tube is not advisable, as it can cause increased negative pressure in the pleural space and lead to tissue damage or bleeding. Stripping the chest tube involves applying manual pressure along the tubing to force out any clots or debris that may obstruct drainage. However, this practice is not recommended, as it can cause more harm than good. The nurse should only milk the chest tube gently and intermittently if ordered by the provider and if there is evidence of obstruction.
