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 ["18"]
Explanation
The client is to receive furosemide 60 mg every 12 hours.
The drug is available in a concentration of 10 mg/mL, so the nurse should administer 6 mL of medication (60 mg / 10 mg/mL).
The nurse plans to administer the dosage over 20 minutes, so the infusion rate should be 18 mL/hour (6 mL / (20 minutes / 60 minutes/hour)).
Correct Answer is ["56"]
Explanation
Answer: 56 gtt/min.
Rationale:
To calculate the infusion rate in gtt/min, we'll use the following formula:
Infusion Rate (gtt/min) = Volume (mL) / Time (min) x Drop Factor (gtt/mL)
1. Convert volume to mL:
2 liters = 2000 mL
2. Convert time to minutes:
12 hours = 12 x 60 = 720 minutes
3. Plug in the values:
Infusion Rate (gtt/min) = 2000 mL / 720 min x 20 gtt/mL
4. Calculate:
Infusion Rate (gtt/min) ≈ 55.56 gtt/min
5. Round to the nearest whole number:
Infusion Rate (gtt/min) ≈ 56 gtt/min
Therefore, the nurse should regulate the infusion to 56 gtt/min.
