A nurse is teaching a client who has a new prescription for sucralfate 1 g PO BID.
Available is sucralfate 1 g/10 mL. How many tsp should the nurse instruct the client to self-administer per dose? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero.). tsp.
The Correct Answer is ["2"]
Step 1 is to determine the amount of medication needed. The order is for 1 g and the available medication is 1 g/10 mL. So, we calculate 1 g ÷ 1 g/10 mL = 10 mL. Since 1 tsp is approximately 5 mL, we then calculate 10 mL ÷ 5 mL/tsp = 2 tsp. So the correct answer is 2 tsp.

Correct Answer is ["9.4"]
Explanation
Step 1 is to calculate the dose to be administered which is 300 mg. Step 2 is to calculate the concentration of the available medication which is 160 mg/5 mL. Step 3 is to calculate the volume to be administered as (300 mg ÷ (160 mg/5mL)) = 9.375 mL.
So, the correct answer is, after analyzing all steps, the nurse should administer 9.4 mL per dose (rounded to the nearest tenth).
Correct Answer is ["1.9"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg. Given that 1 kg = 2.2 lb, we calculate:
165 lb ÷ 2.2 = 75 kg
Step 2 is to calculate the volume of naloxone to be administered. The prescribed dosage is 10 mcg/kg, so we first determine the total dose:
10 mcg/kg × 75 kg = 750 mcg
Next, we convert the available concentration of naloxone from mg/mL to mcg/mL:
0.4 mg/mL × 1000 mcg/mg = 400 mcg/mL
Now, we calculate the required volume by dividing the total dose by the concentration:
750 mcg ÷ 400 mcg/mL = 1.875 mL
Rounding to the nearest tenth, the correct amount to administer is 1.9 mL.
