Sagot :
Answer:
15.8757 grams
Explanation:
35lbs = 15.8757kg
15.8757 * 2 = 31.7514 ml of d50
the concentration states that g=1/2ml
31.7514/2 = 15.8757 grams of dextrose.
Answer:
16 grams of dextrose
Explanation:
Weight in Kilograms
The first step in solving this dosage calculation problem is to convert the patient's weight from pounds (lb) to kilograms (kg). To do so, multiply the weight in pounds by a conversion factor reflecting the proportion that there are 2.2 lb in each kg.
35 lb × (1 kg / 2.2 lb)
lb in both numerator and denominator will cancel each other out, leaving kg as the remaining unit.
(35 × 1 kg) / 2.2
= 15.909
≈ 16 kg
Ordered Amount
Next, this weight in kilograms is used to determine how many milliliters (mL) of dextrose (D50) the patient should be administered, per the written prescription usually under the instruction of a provider (e.g. physician). This is known as the ordered amount. To do so, multiply the weight in kilograms by the rate of mL per kg.
16 kg × (2 mL / kg)
kg in both numerator and denominator will cancel each other out, leaving mL as the remaining unit.
(16 × 2 mL) / 1
= 32 mL
Dose to Administer
Finally, the amount of dextrose to administer is determined by multiplying the ordered amount (32 mL) by the concentration of the medication within the pre-filled syringe, typically provided from the pharmacy's stock of available medications. This is called the dosage strength. The following formula represents the described calculation:
ordered amount × dosage strength = administered dose
32 mL × (25 g / 50 mL)
mL in both numerator and denominator will cancel each other out, leaving grams (g) as the remaining unit of measurement.
(32 × 25 g) / 50
= 800 g / 50
= 16 g
16 grams of dextrose should be administered to the patient experiencing hypoglycemia.
