The healthcare provider prescribes penicillin 200,000 units intramuscularly for a patient with pneumonia.

The available vial is labeled “Penicillin 500,000 units/mL”. How much penicillin should be administered to the patient? (Enter numerical value only.

If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.4"]

Step 1 is to determine the amount of penicillin in each milliliter (mL) of the available solution. The vial is labeled as “Penicillin 500,000 units/mL”.

Step 2 is to divide the prescribed dose by the concentration per mL. So, the calculation is 200,000 units ÷ 500,000 units/mL. The result is 0.4 mL.

Correct Answer is B

Explanation

Choice A rationale
Similar to, while spicy foods can irritate the urinary tract, they do not have a direct impact on the care and management of an indwelling urinary catheter after a TURP3.
Choice B rationale
As in, drinking 3 liters of water each day is important as it helps flush the bladder and reduce the risk of urinary tract infections, which are a common complication after a TURP3.
Choice C rationale
As in, clamping the catheter is not typically recommended as it can lead to urinary retention and increase the risk of urinary tract infections.
Choice D rationale
As in, avoiding driving for 2 weeks is a general recommendation after any major surgery to allow the body time to heal, but it does not directly relate to the care of an indwelling urinary catheter.
