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 D
Explanation
Choice A rationale
Hypomagnesemia is not typically a primary concern for newborns of mothers with diabetes mellitus. While it can occur in newborns, it is not directly related to macrosomia or maternal diabetes.
Choice B rationale
Hypocalcemia can occur in newborns, especially preterm infants, infants of diabetic mothers, and those with perinatal asphyxia. However, it is not the primary concern in this scenario.
Choice C rationale
Hyperbilirubinemia can occur in newborns for a variety of reasons, including prematurity, blood group incompatibility, and other factors. While infants of diabetic mothers may have an increased risk of jaundice, it is not the primary concern in this scenario.
Choice D rationale
Hypoglycemia is the correct answer. Infants of diabetic mothers are at risk for hypoglycemia after birth. During pregnancy, the fetus produces extra insulin in response to the mother’s high blood glucose levels. After birth, the newborn continues to produce extra insulin for a short time until it adjusts to normal glucose-insulin balance. This can lead to hypoglycemia, which is a primary concern and requires immediate attention.
Correct Answer is B
Explanation
Choice A rationale
Inserting an indwelling urinary catheter is not the priority nursing action. While it may be necessary later, especially if the client goes to surgery, it is not the immediate concern.
Choice B rationale
Initiating IV access is the correct action. The client is losing blood rapidly, has hypotension, and tachycardia. IV access will allow IV fluids and blood to be administered quickly if hypovolemia develops.
Choice C rationale
Witnessing the signature for informed consent for surgery is not the priority nursing action. While consent will be necessary if the client needs a cesarean section, the immediate concern is stabilizing the client.
Choice D rationale
Preparing the abdominal and perineal areas is not the priority nursing action. This would be done as part of surgical preparation if a cesarean section is needed, but it is not the immediate concern.
