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. Dyspnea:
Dyspnea (shortness of breath) is a common symptom in emphysema due to the destruction of alveolar walls and the resulting reduction in surface area for gas exchange. As the disease progresses, the patient experiences increasing difficulty in breathing, especially during exertion or when the disease becomes more severe.

B. Barrel chest:
A barrel chest is often seen in emphysema, as it results from hyperinflation of the lungs. The increased air trapping due to damaged alveoli causes the chest to expand and become rounded, leading to the characteristic "barrel chest" appearance. This happens because the lungs are constantly overinflated, and the chest wall becomes rigid and rounded as a result.

D. Clubbing of the fingers:
Clubbing of the fingers can occur in chronic respiratory conditions like emphysema due to prolonged hypoxia (low oxygen levels in the blood). This is a compensatory mechanism that involves changes in the nails and fingers. The tips of the fingers become rounded and bulbous over time, and this is commonly associated with long-standing pulmonary diseases.

Oral candidiasis, also known as thrush, is a fungal infection of the mouth caused by Candida albicans. It is a common adverse effect of inhaled corticosteroids, such as fluticasone, which can suppress the normal flora of the oral cavity and create a favorable environment for fungal growth. It manifests as white patches or plaques on the tongue, palate, or cheeks that can be scraped off.

a) Polyuria, or excessive urination, is not an adverse effect of fluticasone. It can be caused by diabetes mellitus, diabetes insipidus, diuretics, or kidney disease.
b) Hypoglycemia, or low blood glucose level, is not an adverse effect of fluticasone. It can be caused by
insulin overdose, oral hypoglycemic agents, alcohol intake, or prolonged fasting.
c) Hypertension, or high blood pressure, is not an adverse effect of fluticasone. It can be caused by stress, obesity, smoking, salt intake, or kidney disease.
