A client who is experiencing indigestion receives a prescription for magnesium hydroxide 1200 mg by mouth every 6 hours. The bottle is labeled "Magnesium Hydroxide, USP 400 mg per 5 mL." How many ounces should the nurse instruct the client to take with each dose? (Enter numerical value only.)
The Correct Answer is ["0.51 "]
The client receives a prescription for magnesium hydroxide 1200 mg by mouth every 6 hours.
The bottle is labeled "Magnesium Hydroxide, USP 400 mg per 5 mL", so the client should take 15 mL of medication with each dose (1200 mg / 400 mg/5 mL * 5 mL).
Since 1 ounce is equivalent to 29.5735 mL, the client should take 0.51 ounces of medication with each dose (15 mL / 29.5735 mL/ounce).

Correct Answer is ["375"]
Explanation
To calculate the number of milliliters that remain to be infused, we can use the following formula: Volume remaining = Total volume - Volume infused
In this case, the total volume is 1000 mL and the volume infused is:
125 mL/hour x 5 hours = 625 mL So the volume remaining is:
1000 mL - 625 mL = 375 mL.
Correct Answer is ["2.4"]
Explanation
Step 1 is to identify the ordered dose and the correct available concentration based on the route of administration.
Ordered Dose: 4,780 IU
Route: IV (Intravenous)
Available Strength: 10,000 IU
Reconstitution Volume for IV: 5 mL
Step 2 is to calculate the volume to administer in milliliters (mL)
Volume = (Ordered Dose ÷ Available Dose) × Available Volume
Volume = (4,780 ÷ 10,000) × 5
4,780 ÷ 10,000 = 0.478
0.478 × 5 = 2.39
Volume to administer = 2.39 mL
Step 3 is to round to the nearest tenth
2.39 rounds to 2.4
Answer: 2.4
