we have demerol 50 milligrams/milliliter in stock and a patient is to be given 35 milligrams of demerol every 4 hours.
so we can use the simple ratio method to find the number of milliliters that should be given per dose.
therefore, every dose of demerol of 0.7 milliliter should be given to the patient.
to find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%
here the decrease = 45 - 18 = 27
percent decrease = × 100%
= × 100% = 60%
range provides provides context for the mean, median and mode. to find the mode, identify which value in the data set occurs most often. range, which is the difference between the largest and smallest value in the data set, describes how well the central tendency represents the data.
