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.)

A. Administration of a prescribed bronchodilator is typically recommended approximately 30 minutes prior to meals rather than 1 hour. This pharmacological timing helps reduce dyspnea and facilitates easier deglutition and mastication by improving airflow. Using it too early may result in the peak therapeutic effect tapering off before the client finishes the meal.

B. Consuming 3 large meals each day is contraindicated for clients with chronic obstructive pulmonary disease because a distended stomach can exert upward pressure on the diaphragm. This abdominal crowding significantly increases the work of breathing and leads to early satiety or respiratory distress. Clients are instead encouraged to eat 5 to 6 small, frequent, nutrient-dense meals.

C. The nurse should instruct the client to limit water or fluid intake during the actual mealtime to prevent premature gastric distention. Early fullness from fluids reduces the client’s ability to consume essential solid nutrients and calories required to support the increased metabolic demands of labored breathing. Fluids should be consumed between meals to maintain adequate hydration and thin secretions.

D. Reducing protein intake is inappropriate because these clients require high-protein and high-calorie diets to prevent muscle wasting and support the respiratory muscles. The metabolic cost of breathing in chronic obstructive pulmonary disease is significantly elevated, often leading to a state of malnutrition or cachexia. Protein is vital for tissue repair and maintaining the functional integrity of the diaphragm.

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.
