Mary has an order to be given Atropine gr. 1/150 sc on call from the O.R. The O.R. has called for Mary, so you need to prepare her injection right away. The label states : Atropine 0.4 mg/ml. How many ml are you to administer?0.35 ml0.5 ml1 ml1.5 ml
Maggie has Morphine sulfate gr 1/6, IM, q6 hours prn, for leg pain. She is complaining of pain at a 7 on a scale of 1-10. The label on the box of syringes states Morphine sulfate 15mg/2ml. How many ml will you administer? 0.66 ml1.33 ml1.45 ml1.66 ml
To calculate the amount of Atropine to administer, we need to convert the dose from grains to milligrams and then divide by the concentration.
1. First, convert the Atropine dose from grains to milligrams. Remember that 1 grain is approximately 64.8 milligrams.
1/150 grain × 64.8 mg/grain = 0.432 mg
2. Next, divide the dose (0.432 mg) by the concentration (0.4 mg/ml) to find the volume:
Volume = Dose / Concentration
Volume = 0.432 mg / 0.4 mg/ml
Calculating this gives us:
Volume = 1.08 ml
Therefore, you should administer 1.08 ml of Atropine.
For the second question:
1. Convert the Morphine dose from grains to milligrams. 1 grain is approximately 64.8 milligrams.
1/6 grain × 64.8 mg/grain = 10.8 mg
2. Divide the dose (10.8 mg) by the concentration (15 mg/2 ml) to find the volume:
Volume = Dose / Concentration
Volume = 10.8 mg / 15 mg/2 ml
Calculating this gives us:
Volume = 1.44 ml
Therefore, you should administer 1.44 ml of Morphine sulfate.
To determine the amount of medication to administer, we can use the equation:
Amount to administer (in ml) = Desired dose (in mg) / Concentration (in mg/ml)
1. For Mary's Atropine injection:
The desired dose is 1/150 gr (gr means grain) or 0.4 mg.
The concentration is 0.4 mg/ml.
Plugging these values into the equation:
Amount to administer = 0.4 mg / 0.4 mg/ml = 1 ml
Therefore, you are to administer 1 ml of Atropine to Mary.
2. For Maggie's Morphine injection:
The desired dose is 1/6 gr or approximately 15 mg.
The concentration is 15 mg/2 ml.
Plugging these values into the equation:
Amount to administer = 15 mg / (15 mg/2 ml) = 1 ml / (2/15) = 7.5 ml / 2 = 3.75 ml
Since the question provides options in ml, we need to round our answer to the nearest tenth. Therefore, you will administer 3.8 ml of Morphine to Maggie.
None of the given options match with the calculated amount for Maggie's Morphine injection, so please double-check the given options or consult a healthcare professional for the correct dosage.
