A nurse is preparing to administer ampicillin 500 mg via intermittent IV bolus over 30 min. Available is 500 mg ampicillin in 50 mL dextrose 5% in water (DSW). The nurse should set the pump to deliver how many mL/hr?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

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.

This statement indicates an understanding of the teaching, as weight loss is one of the most effective ways to decrease the number of nightly apneic episodes in clients who are obese and have obstructive sleep apnea. Obstructive sleep apnea is a condition in which the upper airway collapses or becomes blocked during sleep, causing pauses in breathing and hypoxia. Obesity is a major risk factor for obstructive sleep apnea, as excess fat tissue around the neck and throat can narrow the airway and increase its collapsibility. Losing weight can reduce the pressure on the airway and improve its patency.

b) "I sleep better if I take a sleeping pill at night." This statement indicates a lack of understanding of the teaching, as sleeping pills are not recommended for clients who have obstructive sleep apnea. Sleeping pills can worsen the condition by relaxing the muscles of the throat and tongue, which can further obstruct the airway and decrease the arousal response to hypoxia. The nurse should advise the client to avoid sleeping pills and other sedatives or alcohol before bedtime.
c) "It might help if I tried sleeping only on my back." This statement indicates a lack of understanding of the teaching, as sleeping on the back is not helpful for clients who have obstructive sleep apnea. Sleeping on the back can increase the risk of airway obstruction by allowing gravity to pull the tongue and soft palate backward, which can block the airway and cause snoring and apnea. The nurse should suggest that the client try sleeping on the side or elevate the head of the bed to prevent this.
d) "I should get a humidifier to run at my bedside at night." This statement indicates a lack of understanding of the teaching, as a humidifier is not likely to decrease the number of nightly apneic episodes in clients who have obstructive sleep apnea. A humidifier can moisten the air and ease breathing for clients who have dry or irritated nasal passages, but it does not address the underlying cause of airway obstruction or hypoxia. The nurse should inform the client that a humidifier may not be effective for obstructive sleep apnea and may increase the risk of infection or mold growth if not cleaned properly.
