A nurse is preparing to administer procaine penicillin G 1,200,000 units IM to a client who has a gonococcal infection. Available is procaine penicillin G injection 600,000 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 ["2"]
To calculate the correct dosage, the nurse needs to divide the total units prescribed by the concentration of units per milliliter available. In this case, 1,200,000 units prescribed divided by 600,000 units per mL results in 2 mL.

Correct Answer is B
Explanation
A. Offering the medication preemptively is not indicated because the prescription specifies administration only if saturation occurs within 15 minutes.
B. Administering the medication once if the client saturates the perineal pad within 15 minutes aligns with the prescription's directive to use oxytocin to manage excessive bleeding promptly.
C. Waiting 15 minutes after saturation does not align with the urgency indicated by the prescription, which specifies immediate administration upon saturation.
D. Administering the medication each time the pad saturates within 15 minutes could lead to excessive dosing and is not in accordance with the prescription's one-time use instruction.
Correct Answer is ["12.2"]
Explanation
To calculate the IV pump setting, first convert the newborn's weight from pounds to kilograms, knowing that 1 pound is equivalent to 0.453592 kilograms. The newborn weighs 6.7 pounds, which is approximately 3.039 kg (6.7 lb * 0.453592 kg/lb). Next, calculate the total amount of potassium needed per hour by multiplying the newborn's weight in kilograms by the prescribed dose: 0.4 mEq/kg/hr * 3.039 kg = 1.2156 mEq/hr. Since the available potassium is 10 mEq in 100 mL, this means there is 0.1 mEq/mL. To find out how many mL/hr to administer, divide the total mEq needed per hour by the concentration: 1.2156 mEq/hr ÷ 0.1 mEq/mL = 12.156 mL/hr. Rounded to the nearest tenth, the IV pump should be set to deliver 12.2 mL/hr.
