1 g = ___ mg - ANS1000 mg
1 kg=___lb - ANS2.2 lb
1 kg=__g - ANS1000 g
1 L= ____ mL - ANS1000 mL
1 mg= _____ mcg - ANS1000 mcg
1 oz. =__mL - ANS30 mL
1 tbsp= ___ mL - ANS15 mL

A nurse is being concerned for a affected person who weighs 128 lb. What is the patient's
weight in kg?
(Round to nearest 10th. Use a main 0 if it applies. Do not use a trailing zero.) - ANSAnswer:
58.2 kg
Follow these steps for the Ratio and Proportion technique of calculation:
Step 1: What is the unit of size the nurse ought to calculate? Kg
Step 2: Set up an equation and solve for X.
2.2 lb/ 1 kg = Client's weight in lb /X kg
2.2 lb/ 1 kg = 128 lb / X kg
X kg = fifty eight.181818 kg
Step 3: Round if essential. Fifty eight.181818 kg = fifty eight.2 kg
Step 4: Determine whether the load conversion makes sense. If the consumer weighs 128 lb
and 2.2 lb equals 1 kg, it makes experience that the client weighs 58.2 kg.
A nurse is getting ready a label for amoxicillin oral suspension that became simply
reconstituted. The nurse have to document on the label that the drugs have to be discarded
what number of days following reconstitution?
(Picture of Amoxicillin label:
, Front: Brand name, Amoxicillin for oral suspension, four hundred mg/5mL, 75 mL (while
reconstituted), while reconstituted: each five mL consists of: Amoxicillin because the
trihydrate 400mg)
back: Usual dosage: administer every 12 hours. Internet contents: Equivalent of 6 grams of
amoxicillin). Directions for mixing: faucet bottle until all powder flows freely; Add
aproximately 1/3 total amount of water for reconstitution (general=fifty one mL); shake
vigorously to wet powder; every five mL carries: Amoxicillin 400mg. Keep tightly closed.
Shake well earlier than the use of. Rerigeration is finest however not required. Discard
suspension after 14 days.) - ANSAnswer: 14 days
Explanation: According to the medicine label, the amoxicillin oral suspension must be
discarded 14 days following reconstitution to reduce the risk of injury to the client.
A nurse is preparing to manage 2 Tbsp of ibuprofen to a purchaser. How many mL must the
nurse administer in keeping with dose?
(Round to the closest whole range. Use a main zero if it applies. Do now not use a trailing
zero.) - ANSAnswer: 30 mL
Follow those steps for the Ratio and Proportion technique of calculation:
Step 1: What is the unit of size the nurse must calculate? ML
Step 2: What is the dose the nurse must administer? Dose to manage = Desired 2 Tbsp
Step three: What is the dose to be had? Dose to be had = Have 1 mL
Step 4: Should the nurse convert the devices of dimension? Yes (Tbsp does no longer equal
mL)
1 Tbsp / 15 mL = 2 Tbsp / X mL
X mL = 30 mL
Step 5: Round if important.
Step 6: Determine whether or not the amount to manage makes feel. If the prescription
reads 2 Tbsp and 1 Tbsp equals 15 mL, it makes feel to manage 30 mL. The nurse need to
administer ibuprofen 30 mL.
A nurse is preparing to manage 750,000 devices of procaine penicillin G IM. Available is
procaine penicillin G injection six hundred,000 units/mL. How many mL must the nurse
administer in keeping with dose?
(Round answer to nearest 10th. Use a main zero if it applies. Do no longer use a trailing
zero.) - ANSAnswer: 1.Three mL
Follow those steps for the Ratio and Proportion approach of calculation:
Step 1: What is the unit of dimension the nurse need to calculate? ML
Step 2: What is the dose the nurse ought to administer? Dose to manage = Desired 750,000
units
Step three: What is the dose available? Dose to be had = Have 600,000 gadgets
Step four: Should the nurse convert the gadgets of dimension? No
Step 5: What is the quantity of the dose to be had? 1 mL
Step 6: Set up an equation and solve for X.
