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
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
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
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
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.

A. Painful areas should be rubbed gently until the pain subsides. B. Wearing gloves when handling cold items guards against painful spasms. C. Return appointments will be needed for IV pain medication. D. Enrolling in a pain clinic can provide pain relief alternatives.

Correct Answer is B

Explanation

Choice A rationale
Rubbing painful areas gently until the pain subsides is not typically recommended for managing pain in Raynaud’s disease. This could potentially cause more harm than good19.
Choice B rationale
Wearing gloves when handling cold items can help guard against painful spasms in Raynaud’s disease. Cold temperatures can trigger Raynaud’s attacks, so protecting the hands from cold is a key part of managing the condition19.
Choice C rationale
The need for return appointments for IV pain medication is not typically a primary component of pain management in Raynaud’s disease. Pain in Raynaud’s disease is usually managed through lifestyle modifications and medications19.
Choice D rationale
While enrolling in a pain clinic can provide pain relief alternatives, it’s not the first line of management for pain in Raynaud’s disease. The primary management strategies include avoiding cold exposure and using medications to improve blood flow19.
