A nurse is preparing to administer 250 mg of an antibiotic intramuscularly to a pregnant client for a sexually transmitted infection.
The available medication is 3 g/5 mL. How many mL should the nurse administer per dose? (This is a medical math querry no options provided) .
The Correct Answer is ["0.42"]
Step 1: Convert grams to milligrams: 3 g = 3000 mg Step 2: Find out how many milligrams are in each milliliter: 3000 mg ÷ 5 mL = 600 mg/mL Step 3: Calculate how many milliliters to administer for a 250 mg dose: 250 mg ÷ 600 mg/mL = 0.42 mL So, the nurse should administer
0.42 mL of the antibiotic per dose.

Correct Answer is C
Explanation
Choice A rationale
Elevating the client’s legs is not the first action to take. While it can help with circulation, it does not directly address the issue of late decelerations.
Choice B rationale
Administering oxygen using a nonrebreather mask can be beneficial as it can increase the amount of oxygen available to the fetus. However, it is not the first action to take.
Choice C rationale
Placing the client in the lateral position is the correct action. This position can help improve placental blood flow and potentially improve the oxygen supply to the fetus.
Choice D rationale
Increasing the rate of maintenance IV infusion is not the first action to take. While it can help maintain hydration and blood pressure, it does not directly address the issue of late decelerations.
