Your patient is ordered to receive 20 units Pitocin in D5%W 500 mLs at 12 milliunits/minute.
What flow rate will you set the IV pump to deliver? Numeric values only.
The Correct Answer is ["mLs\/hr."]
Step 1 is to convert the order from milliunits/minute to units/hour. So, 12 milliunits/minute is equal to 0.72 units/hour. Step 2 is to calculate the total units in the IV bag, which is 20 units. Step 3 is to calculate the total volume of the IV bag, which is 500 mL. Step 4 is to calculate the flow rate. So, (0.72 units/hour ÷ 20 units) × 500 mL = 18 mL/hr. So, the correct flow rate to set on the IV pump is 18 mL/hr.

Explanation
Choice A rationale:
The first sign of breast development is not menarche. It is a part of puberty, but it is not the definition of menarche.
Choice B rationale:
A woman’s first sexual experience is not menarche. Menarche refers to a specific biological event.
Choice C rationale:
Menarche is defined as a woman’s first menstrual period. This is the correct definition.
Choice D rationale:
A full hormonal cycle is not menarche. While the hormonal cycle is related to menstruation, it is not the definition of menarche.
Correct Answer is D
Explanation
Choice A rationale:
The face as the presenting part is not indicated by LSA. LSA stands for Left Sacrum Anterior, which indicates the baby’s position in the womb.
Choice B rationale:
The shoulder as the presenting part is not indicated by LSA. LSA refers to the baby’s position, not the presenting part.
Choice C rationale:
The occiput as the presenting part is not indicated by LSA. LSA refers to the baby’s position, not the presenting part.
Choice D rationale:
The buttocks as the presenting part is indicated by LSA. LSA (Left Sacrum Anterior) means the baby’s sacrum (buttocks) is presenting, and it is oriented to the mother’s left side and is facing forward (anterior).
