A nurse is preparing to administer procaine penicillin G 800000units IM to a client who has a gonococcal infection. Available is procaine penicillin G suspension for injection 600.000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.3"]
Given:
Desired dose of procaine penicillin: 800,000 units
Concentration of procaine penicillin suspension: 600,000 units/mL
Step 1: Set up the proportion:
Desired dose (units) / Volume to administer (mL) = Concentration (units/mL)
Step 2: Substitute the values:
800,000 units / Volume = 600,000 units/mL
Step 3: Solve for the unknown volume:
Volume = 800,000 units / 600,000 units/mL
Step 4: Calculate the volume:
Volume = 1.333333333 mL
Step 5: Round to the nearest tenth:
Volume ≈ 1.3 mL

Correct Answer is ["188"]
Explanation
Given:
Total volume to be infused: 1,500 mL
Infusion time: 8 hours
Step 1: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 2: Substitute the values:
Infusion rate (mL/hr) = 1,500 mL / 8 hr
Step 3: Calculate the infusion rate:
Infusion rate (mL/hr) = 187.5 mL/hr
Step 4: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 188 mL/hr
Correct Answer is ["0.25"]
Explanation
Given:
Desired dose of phytonadione: 0.5 mg
Concentration of phytonadione injection: 1 mg/0.5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
0.5 mg / Volume = 1 mg/0.5 mL
Step 3: Solve for the unknown volume:
Volume = 0.5 mg / (1 mg/0.5 mL)
Step 4: Calculate the volume:
Volume = 0.25 mL
