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 findings are expected to be assessed in a client who has emphysema, which is a type of chronic obstructive pulmonary disease (COPD) characterized by destruction and enlargement of alveoli, loss of elastic recoil, and air trapping. These changes impair gas exchange and oxygenation, leading to chronic hypoxia and hypercapnia.

a) Dyspnea, or difficulty breathing, is a common symptom of emphysema, as the client has reduced lung capacity and increased work of breathing. Dyspnea may be worse with exertion, stress, or infection, and may cause anxiety and fatigue. The nurse should monitor the client's respiratory rate, rhythm, depth, and effort, and provide oxygen therapy as prescribed.
b) Barrel chest, or increased anteroposterior diameter of the chest, is a physical sign of emphysema, as the client has chronic air trapping and hyperinflation of the lungs. Barrel chest may also cause kyphosis, or curvature of the spine, and reduced chest wall movement. The nurse should measure the client's chest circumference and observe for any deformities or asymmetry.
d) Clubbing of the fingers, or enlargement and rounding of the nail beds, is a late sign of emphysema, as the client has chronic hypoxia and tissue ischemia. Clubbing may also affect the toes and ears, and may indicate pulmonary or cardiac disease. The nurse should inspect the client's nails for shape, color, angle, and capillary refill.

c) Deep respirations are not expected to be assessed in a client who has emphysema, as the client has shallow and rapid breathing due to air trapping and reduced lung compliance. Deep respirations may indicate other conditions, such as metabolic acidosis or anxiety. The nurse should assess the client's arterial blood gas levels and provide reassurance and relaxation techniques as needed.
e) Bradycardia, or slow heart rate, is not expected to be assessed in a client who has emphysema, as the client has tachycardia or normal heart rate due to hypoxia and increased sympathetic stimulation. Bradycardia may indicate other conditions, such as medication side effects, vagal stimulation, or heart block. The nurse should monitor the client's pulse rate, rhythm, quality, and electrocardiogram as indicated.

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.
