A nurse is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the nurse anticipate administering?

Increased anteroposterior diameter of the chest, also known as barrel chest, is a common finding in clients who have COPD with emphysema. It is caused by chronic air trapping and hyperinflation of the lungs, which results in fattening of the diaphragm and widening of the rib cage.

a) Oxygen saturation level 96% is within the normal range of 95% to 100% and does not indicate hypoxemia or impaired gas exchange. Clients who have COPD with emphysema typically have lower oxygen saturation levels, ranging from 88% to 92%.
b) Respiratory alkalosis is a condition in which the blood pH is elevated due to decreased carbon dioxide levels. It is caused by hyperventilation, which can occur in response to hypoxia, anxiety, or pain. Clients who have COPD with emphysema usually have respiratory acidosis, which is a condition in which the blood pH is lowered due to increased carbon dioxide levels. It is caused by hypoventilation, which results from impaired lung function and airway obstruction.
d) Petechiae on chest are small red or purple spots on the skin caused by bleeding from capillaries. They are not a typical finding in clients who have COPD with emphysema, unless they have severe coughing episodes or coagulation disorders. They can indicate infection, inflammation, trauma, or vascular disease.

These responses are correct and explain how albuterol helps the client's breathing. Albuterol is a short- acting beta2-agonist that causes bronchodilation and relieves bronchospasm, which are the main causes of wheezing and dyspnea in clients who have asthma or COPD. By opening the airways, albuterol improves gas exchange and oxygenation.

b) The medication will decrease coughing episodes. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have a direct effect on coughing, which is a reflex response to irritation or obstruction of the airways. Coughing may be beneficial for clearing secretions and mucus from the lungs, but it may also cause bronchoconstriction and inflammation. The nurse should advise the client to use other measures to decrease coughing, such as drinking fluids, using a humidifier, or taking an expectorant.
c) The medication will reduce inflammation. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have an anti-inflammatory effect on the airways, which are often inflamed and swollen in clients who have asthma or COPD. Inflammation can contribute to airway obstruction and mucus production, which impair gas exchange and oxygenation. The nurse should inform the client that albuterol is used for quick relief of acute symptoms, but not for long-term control or prevention of inflammation. The client may need to use another medication, such as an inhaled corticosteroid, to reduce inflammation.
e) The medication will stimulate flow of mucus. This response is incorrect and does not explain how albuterol helps the client's breathing. Albuterol does not have a direct effect on mucus production or clearance, which are often increased in clients who have asthma or COPD. Mucus can cause airway obstruction and infection, which impair gas exchange and oxygenation. The nurse should advise the client to use other measures to stimulate flow of mucus, such as drinking fluids, using a humidifier, or taking an expectorant.
