A nurse is preparing to reconstitute amoxicillin powder. According to the medication label, how many mL of oral suspension should the nurse expect the bottle to contain following reconstitution? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["75"]
The medication label for amoxicillin powder provides the instructions for reconstituting the oral suspension. The nurse should follow these steps:
- Tap the bottle until all the powder is loose.
- Add about 17 mL of water to the bottle (one-third of the total amount of 51 mL).
- Shake the bottle well to mix the powder and water.
- Add the remaining 34 mL of water to the bottle and shake again.
- Check that the final volume of the oral suspension is 75 mL.
The nurse should expect the bottle to contain 75 mL of oral suspension after reconstitution.
This is because each 5 mL of oral suspension contains 400 mg of amoxicillin, and the net contents of the powder are equivalent to 6 grams (6000 mg) of amoxicillin.
Therefore, 6000 mg / 400 mg = 15, which means that 15 doses of 5 mL each are needed to use up all the powder. Multiplying 15 by 5 mL gives 75 mL, which is the final volume of the oral suspension.

Explanation
To calculate the correct dosage of levothyroxine, the nurse should follow these steps:
- Convert the patient's weight from pounds to kilograms: 220 lb ÷ 2.20462 lb/kg = 99.79 kg
- Calculate the total dose of levothyroxine: 5 mcg/kg × 99.79 kg = 498.95 mcg
- Determine the number of tablets to administer: 498.95 mcg ÷ 75 mcg/tablet = 6.65 tablets
Therefore, the nurse should administer 7 tablets of levothyroxine.
Correct Answer is ["1"]
Explanation
This is a question that tests the nurse's ability to calculate drug dosages based on the client's weight and the drug concentration. To solve this problem, the nurse needs to follow these steps:
1. Convert the client's weight from pounds to kilograms by dividing by 2.2. 176 lb / 2.2 = 80 kg.
2. Multiply the client's weight in kilograms by the prescribed dose in micrograms per kilogram to get the total dose in micrograms. 80 kg x 50 mcg/kg = 4000 mcg.
3. Convert the total dose in micrograms to milligrams by dividing by 1000. 4000 mcg / 1000 = 4 mg.
4. Divide the total dose in milligrams by the drug concentration in milligrams per milliliter to get the volume in milliliters. 4 mg / 4 mg/mL = 1 mL.
5. Round the answer to the nearest whole number and add a leading zero if it applies. Do not use a trailing zero. The final answer is 1 mL.
Therefore, the nurse should administer 1 mL of lorazepam IM to the client.
