A nurse is preparing to administer penicillin G potassium 1,000,000 units intermittent IV bolus. The label on the vial indicates to reconstitute with 50 ml of sterile water to make penicillin G potassium 100,000 units/ml. How many ml, should the nurse administer? (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 ["10"]
To determine how many milliliters (mL) of the reconstituted penicillin G potassium to administer, you can use the following calculation:
Given:
- Reconstituted concentration: 100,000 units/mL
- Total dose to be administered: 1,000,000 units
Now, use the formula:
Volume (mL) = Total dose (units) / Concentration (units/mL)
Volume (mL) = 1,000,000 units / 100,000 units/mL
Volume (mL) = 10 mL
So, the nurse should administer 10 mL of the reconstituted penicillin G potassium.

Correct Answer is ["167"]
Explanation
To calculate the infusion rate in mL/hr for dextrose 5% in water 1,000 mL over 6 hours, you can use the following formula:
Infusion Rate (mL/hr) = Total Volume (mL) / Total Time (hr)
Infusion Rate = 1,000 mL / 6 hr ≈ 166.67 mL/hr
Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 167 mL/hr.
Correct Answer is ["300"]
Explanation
To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
1 Tbsp is approximately equal to 15 mL.
Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
Calculate the amount of guaifenesin in the client's dose:
Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.
