A client receives a prescription for vancomycin 500 mg IV every 8 hours. The medication is provided in "500 mg per 100 mL of dextrose 5% in water." To administer the medication over an hour, the nurse should set the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
Answer and Explanation

The Correct Answer is ["100"]

Vancomycin dosage: 500 mg

Concentration of vancomycin solution: 500 mg per 100 mL

Total volume of solution for each dose: 100 mL (since the concentration is 500 mg per 100 mL) To administer 500 mg of vancomycin, we need 100 mL of the solution.

To administer the medication over 1 hour, we need to deliver the entire 100 mL over 1 hour. Therefore, the infusion rate (in mL/hr) would be 100 mL/hr.

Correct Answer is ["0.8"]

Explanation

The vial contains 0.3 mg of medication, which has been reconstituted with 2 mL of sterile water. Therefore, each milliliter of solution contains 0.15 mg of medication.

The prescribed dose is 0.125 mg, so the nurse should administer \( \frac{0.125\ mg}{0.15\ mg/mL} = 0.8333 \) mL of the solution.

After rounding to the nearest tenth, the nurse should administer 0.8 mL of the reconstituted solution to the client every other day.

Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"A"},"F":{"answers":"B"}}

Explanation

A. Rhonchi are abnormal breath sounds that indicate the presence of mucus or fluid in the airways. Finding rhonchi in the right lung suggests the presence of respiratory congestion or obstruction, which may indicate ineffective treatment or ongoing respiratory issues.

B. Symmetric chest expansion indicates equal and adequate movement of both sides of the chest during inhalation. This finding suggests that there are no restrictions or abnormalities in the chest wall or lung tissue, which is indicative of effective treatment.

C. Oxygen saturation greater than 94% indicates adequate oxygenation of the blood, which is a positive indicator of effective treatment, particularly in clients with respiratory issues such as pneumonia or COPD.

D. A PaCO2 level of 55 mm Hg indicates hypercapnia, which is an elevated level of carbon dioxide in the blood. This finding suggests inadequate ventilation or respiratory failure, indicating ineffective treatment.

E. The ability to ambulate without experiencing shortness of breath suggests improved respiratory function and effective treatment, as it indicates adequate oxygenation and ventilation.

F. Diminished breath sounds suggest reduced airflow or lung volume in the affected area. This finding may indicate ongoing respiratory issues or incomplete resolution of the condition, suggesting ineffective treatment.
