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 B
Explanation
Choice A rationale
An Apgar score of 7 is considered fairly low and would typically be associated with a newborn who has more significant health concerns.
Choice B rationale
An Apgar score of 8 is considered to be within the normal range. This score would be consistent with a newborn who has a pink trunk and head, bluish hands and feet, flexed extremities, a weak and slow cry, a heart rate of 130/min, and cries in response to suctioning.
Choice C rationale
An Apgar score of 9 is considered to be within the normal range. However, given the newborn’s weak and slow cry, an Apgar score of 9 would be less likely.
Choice D rationale
An Apgar score of 10 is very unusual, as almost all newborns lose 1 point for blue hands and feet, which is normal for after birth.
Correct Answer is D
Explanation
Choice A rationale
Intermittent abdominal pain following passage of bloody mucus is more commonly associated with labor or conditions like bloody show but not specifically indicative of placenta previa.
Choice B rationale
Increasing abdominal pain with a non-relaxed uterus could be a sign of conditions such as uterine rupture or contractions, but it is not a typical sign of placenta previa. In placenta previa, the uterus is typically soft and non-tender.
Choice C rationale
Abdominal pain with scant red vaginal bleeding could be indicative of several conditions, including early labor or placental abruption, but it is not a typical sign of placenta previa. Placenta previa is usually characterized by painless bleeding.
Choice D rationale
Painless red vaginal bleeding is a classic sign of placenta previa. This occurs because the placenta, which is implanted low in the uterus, near or over the cervical os, begins to separate as the cervix effaces and dilates, leading to bleeding.
