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 A
Explanation
-
Preterm Labor Risk: At 32 weeks of gestation, regular contractions every 5 minutes could indicate the onset of preterm labor. This is concerning because preterm labor can lead to preterm birth, which poses significant risks to the baby's health and development.
-
Frequency and Intensity: These contractions are occurring frequently (every 5 minutes) and are described as stronger than usual Braxton Hicks contractions. This frequency and the strength of the contractions are unusual for Braxton Hicks, which are typically irregular and less intense.
-
Effacement and Cervical Changes: Although the cervix is closed, it is 80% effaced. Effacement means the cervix is thinning, which, in combination with regular contractions, may indicate that the body is preparing for labor.
-
Urinary Leakage: The client also reported urinary leakage earlier in the day, which could be a sign of ruptured membranes (water breaking). This, combined with regular contractions, increases the need for careful monitoring.
Correct Answer is B
Explanation
Choice A rationale
Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause
variable decelerations on fetal monitoring.
Choice B rationale
Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates
or effaces.
Choice C rationale
A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in
placenta previa.
Choice D rationale
Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use
or other uterine stimulants.
