Erthy is given an intravenous antibiotic (gentamicin) at a dose of 7 mg/kg per day for a period of 7 days. This dose will be assessed after a week and adjusted accordingly. The gentamicin will be administered in 87 mL of Normal Saline (NS) over a time period of 20 minutes. Please answer the following questions:

1. How much will Erthy be getting per day in mg based on this order?


2. How much volume of the gentamicin (in mL) should be added to the IV bag; the concentration of gentamicin is 10 mg per mL.


3. By including the volume of the gentamicin solution added to the IV bag (i.e. the volume of the bag will be 87 mL plus the volume of the gentamicin solution), calculate the IV flow rate for this infusion in both mL/min and mL/hr.

Extracted text: Mrs. AB presented at the emergency department on Wednesday night with her 4 year old daughter (Erthy). Both Mrs. AB and Erthy were not feeling well. Erthy was constipated, had very low urine output, a high fever (39.9°C), and tachycardia (elevated heart rate); she also appeared very pale and had cold extremities (hands and feet). Erthy's fever had started on Sunday night and by the time she was at the emergency department, the fever had not subsided. Mrs. AB told the triage nurse that she gave Erthy Motrin® every evening and TylenolTM 2 times a day since Monday morning (i.e. Motrin® was administered a total of 3 times while TylenolTM was administered a total of 6 times before Mrs. AB arrived to the emergency department). At the time of administration, Erthy's weight was 19kg. When the triage nurse asked Mrs. AB how she (the mother) was feeling, Mrs. AB told her she had trouble swallowing and had a swollen lymph node (but no cough); Mrs. AB had a temperature of 37.1°C however had taken an Advil earlier in the day (1 hour before arriving to the emergency department). Based on her symptoms, the triage nurse thinks that Erthy is suffering from sepsis secondary to a UTI (urinary tract infection). He also suspects that Mrs. AB has strep throat (caused by the bacteria streptococcus). The emergency doctor agrees when she sees the family and admits Erthy to the hospital, where she is started on IV fluids and antibiotics. Mrs. AB gets a prescription for Cephalexin.
