A nurse is preparing to infuse 1 liter of 0.9% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many drops/min? Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["31"]
The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min
Infusion rate (gtts/min) = 31.25 gtts/min
Rounding to the nearest whole number, we get 31 gtts/min.

Correct Answer is B
Explanation
Choice A Reason: Linea nigra is a dark vertical line that appears on the abdomen of some pregnant women. It is caused by increased melanin production and usually fades after delivery.
Choice B Reason: Pica is a condition in which a person has an abnormal desire to eat substances that are not food, such as ice, clay, dirt, or chalk. It is more common in pregnant women and may indicate a deficiency in iron or other nutrients.
Choice C Reason: Ballottement is a technique of palpating a floating structure by bouncing it gently and feeling it rebound. In obstetrics, it can be used to detect the presence of the fetus by feeling its head move when the cervix is tapped.
Choice D Reason: Quickening is the first perception of fetal movements by the pregnant woman. It usually occurs between 16 and 20 weeks of gestation.
Correct Answer is ["2 mL"]
Explanation
The correct answer is 2 mL. To calculate the volume to administer, the nurse should use the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 1,200,000 units / 600,000 units/mL
Volume (mL) = 2 mL
Rounding to the nearest whole number, we get 2 mL.
