A nurse is planning to obtain a blood specimen from a newborn via a heel stick.
Which of the following actions should the nurse take?
Cool the newborn's heel prior to the procedure.
Puncture the center of the newborn's heel.
Cleanse the puncture site with alcohol gauze prior to the procedure.
Administer vitamin K 30 minutes prior to each blood draw.
The Correct Answer is C
Choice A rationale
Cooling the newborn’s heel would constrict blood vessels and make it more difficult to obtain a blood sample. Warming the heel is the preferred method to increase blood flow.
Choice B rationale
Puncturing the center of the newborn’s heel is not recommended as it could cause more pain and potential injury to the bone. The puncture should be done on the outer edges of the heel.
Choice C rationale
Cleansing the puncture site with alcohol gauze is essential to reduce the risk of infection and ensure that the sample is not contaminated.
Choice D rationale
Administering vitamin K before each blood draw is unnecessary. Vitamin K is typically given as a one-time dose to prevent bleeding issues, not related to blood draw procedures.

Correct Answer is D
Explanation
Choice A rationale
Repeating the CST isn't necessary with a negative result, which indicates no significant uterine contractions affecting the fetus.
Choice B rationale
Administering an IV fluid bolus is not warranted by a negative CST result.
Choice C rationale
Preparing for a cesarean birth isn't necessary since a negative CST indicates no immediate fetal distress.
Choice D rationale
A negative CST indicates that there are no late decelerations, so the nurse should allow the labor to progress naturally.
Correct Answer is A
Explanation
Choice A rationale
Terbutaline can cause tachycardia. A heart rate of 132/min is significantly higher than normal and could indicate severe cardiovascular effects.
Choice B rationale
While headaches can occur with terbutaline, they are generally not life-threatening and don't require immediate intervention compared to tachycardia.
Choice C rationale
Nasal congestion is a minor side effect and not a priority compared to a significantly elevated heart rate.
Choice D rationale
Tremors are common with terbutaline use, but they are usually not as concerning as a significantly elevated heart rate
