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 A

Explanation

Choice A rationale
An ABO incompatibility reaction can occur if a patient receives the wrong type of blood during a blood transfusion. Symptoms of an ABO incompatibility reaction include lower back pain and hypotension, which are serious and should be reported immediately to the healthcare provider.
Choice B rationale
A delayed painful rash with urticaria is not typically a symptom of an ABO incompatibility reaction. While it could indicate an allergic reaction, it is not as immediate or potentially life-threatening as the symptoms in Choice A1.
Choice C rationale
Acute rhinitis and nasal stuffiness are more commonly associated with respiratory infections, not ABO incompatibility reactions. These symptoms are not typically a direct result of a blood transfusion.
Choice D rationale
Arthritic joint changes and chronic pain are not associated with ABO incompatibility reactions. These symptoms are more likely related to long-term conditions like arthritis.

A. Activity level of bowel sounds. B. Level and amount of physical activity. C. Eating patterns of dietary intake. D. Color and consistency of feces.

Correct Answer is C

Explanation

Choice A rationale
While the activity level of bowel sounds can provide information about the functioning of the gastrointestinal system, it is not the most important data to manage the patient’s pain from chronic pancreatitis.
Choice B rationale
The level and amount of physical activity can affect the patient’s pain level, but it is not the most crucial data for managing pain in chronic pancreatitis.
Choice C rationale
Eating patterns of dietary intake are the most important data to manage the patient’s pain. In chronic pancreatitis, certain foods can exacerbate the pain. Understanding the patient’s dietary habits can help in providing appropriate dietary modifications.
Choice D rationale
The color and consistency of feces can provide information about the patient’s digestive health, but it is not the most important data to manage the patient’s pain from chronic pancreatitis.
