You have just started working in an Urgent Care Clinic as a nurse.  Mom brings in her 3 year old little boy, Brandon.  Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby!  He's also been pulling a lot at his right ear and sounds congested.  At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg.  Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips.  His temperature is 39C, other vitals signs are normal.  Though he looks ill he appears to be medically stable.  The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom.  The orders include:  push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of amoxicillin at a concentration of 40mg/kg given twice daily (total of 80mg/kg daily).  Now you need to explain a few things to Mom as she's looking frantic - after all this is baby number one and NEVER gets sick!  Be sure to base dosing of medications on his HEALTHY weight of 32 pounds. Since he is usually a healthy toddler you can assume that the difference in his usual weight (at the Pediatrician) from today's weight is probably due to dehydration.  Thus "push fluids"  Based on the weights provided, how many cubic centimeters of fluid does Brandon need to take in to get back to his health weight? You tell Mom that over-the-counter ibuprofen liquid comes in a concentration of 100 mg/5 cc (5 cc = 1 teaspoon).  How many ccs of ibuprofen should Mom give Brandon should his temperature rise above 38C?  And what is 38C in F, Mom is not familiar with the metric system.  You tell Mom the pharmacy will give fill a prescription for Amoxicillin liquid at a concentration of 250mg/cc.  But you need to tell her, based on the dosing by the doctor, how many ccs of amoxicillin she should give Brandon twice daily so that he indeed receives 40 mg/kg with each dose

Question

You have just started working in an Urgent Care Clinic as a nurse.  Mom brings in her 3 year old little boy, Brandon.  Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby!  He's also been pulling a lot at his right ear and sounds congested.  At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds.

On exam today, his weight is 12.5 kg.  Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips.  His temperature is 39C, other vitals signs are normal.  Though he looks ill he appears to be medically stable.  The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom.  The orders include:  push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of amoxicillin at a concentration of 40mg/kg given twice daily (total of 80mg/kg daily).  Now you need to explain a few things to Mom as she's looking frantic - after all this is baby number one and NEVER gets sick!  Be sure to base dosing of medications on his HEALTHY weight of 32 pounds.

  1. Since he is usually a healthy toddler you can assume that the difference in his usual weight (at the Pediatrician) from today's weight is probably due to dehydration.  Thus "push fluids"  Based on the weights provided, how many cubic centimeters of fluid does Brandon need to take in to get back to his health weight?
  2. You tell Mom that over-the-counter ibuprofen liquid comes in a concentration of 100 mg/5 cc (5 cc = 1 teaspoon).  How many ccs of ibuprofen should Mom give Brandon should his temperature rise above 38C?  And what is 38C in F, Mom is not familiar with the metric system.
  3.  You tell Mom the pharmacy will give fill a prescription for Amoxicillin liquid at a concentration of 250mg/cc.  But you need to tell her, based on the dosing by the doctor, how many ccs of amoxicillin she should give Brandon twice daily so that he indeed receives 40 mg/kg with each dose
Expert Solution
Introduction

Concentration of a solution is usually defined as the mass of solute present in a given amount of solution. Temperature is the measure of the hotness or coldness of a system. It is measured using thermometer in day to day life.

 

Given data

Concentration of ibuprofen is 10 mg/kg

Concentration of amoxicillin is 40 mg/kg

Body weight of the examined child is 12.5 kg.

Healthy body weight of a child is 32 pounds.
