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 ["33"]
Explanation
Rationale:
Given:
Total dose of Potassium Chloride: 30 mEq
Volume of solution: 100 mL
Infusion rate: 10 mEq/hour
Step 1: Determine the concentration of Potassium Chloride in the solution:
Concentration (mEq/mL) = Total Potassium Chloride (mEq) / Volume of solution (mL)
Concentration (mEq/mL) = 30 mEq / 100 mL
Concentration (mEq/mL) = 0.3 mEq/mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Infusion rate (mEq/hr) / Concentration (mEq/mL)
Infusion rate (mL/hr) = 10 mEq/hr / 0.3 mEq/mL
Infusion rate (mL/hr) = 33.33 mL/hr
Step 3: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 33 mL/hr
Correct Answer is ["600"]
Explanation
Given:
Volume of fluid: 200 mL
Infusion time: 20 minutes
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Convert infusion time from minutes to hours:
Infusion time (hr) = 20 minutes / 60 minutes/hr
Infusion time (hr) = 1/3 hour
Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 200 mL / (1/3) hr
Flow rate (mL/hr) = 200 mL x (3/1) hr
Flow rate (mL/hr) = 600 mL/hr
