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.)
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 D
Explanation
Choice A rationale
Brown, rough, greasy, wart-like papules on the face are not typically associated with overexposure to PUVA treatment. These symptoms could be indicative of a different skin condition.
Choice B rationale
Thick skin plaques topped by silvery-white scales are characteristic of psoriasis vulgaris, not overexposure to PUVA treatment. PUVA is used to treat these symptoms, not cause them.
Choice C rationale
Needing sunglasses because sunlight hurts the eyes is not a typical sign of overexposure to PUVA treatment. This could be a sign of a different issue, such as an eye condition or side effect from a different medication.
Choice D rationale
Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. If a patient is overexposed to PUVA, they may experience a burning sensation, discomfort, and redness at the treatment site.
