The client is prescribed magnesium hydroxide 5 oz PO for heartburn. The nurse has administered the prescribed dose 3 times today. How many mL of magnesium hydroxide has the client ingested? (Enter numeric value only.)
The Correct Answer is ["133"]
Given:
Prescribed dose: 1.5 oz
Number of doses administered: 3 times
Step 1: Convert ounces to milliliters:
1 ounce (oz) = 29.5735 mL
Prescribed dose in mL = 1.5 oz x 29.5735 mL/oz = 44.36025 mL
Step 2: Calculate the total volume ingested:
Total volume (mL) = Prescribed dose per dose (mL) x Number of doses
Total volume (mL) = 44.36025 mL/dose x 3 doses
Total volume (mL) = 133.08075 mL
Step 3: Round to the nearest whole number:
Total volume (mL) ≈ 133 mL

Correct Answer is ["375"]
Explanation
Given:
Total volume of infusion: 1000 mL
Infusion rate: 125 mL/hour
Infusion started 5 hours ago
Step 1: Calculate the volume infused in 5 hours:
Volume infused = Infusion rate (mL/hour) x Time (hours)
Volume infused = 125 mL/hour x 5 hours
Volume infused = 625 mL
Step 2: Calculate the remaining volume:
Remaining volume = Total volume - Volume infused
Remaining volume = 1000 mL - 625 mL
Remaining volume = 375 mL
Correct Answer is ["0.7"]
Explanation
Given:
Ordered dose of Hydroxyzine: 35 mg
Concentration of Hydroxyzine: 50 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
35 mg / Volume = 50 mg/mL
Step 3: Solve for the unknown volume:
Volume = 35 mg / (50 mg/mL)
Volume = 35 mg x (1 mL / 50 mg)
Volume = 0.7 mL
