A nurse is assessing a client who has a grade 2 placental abruption.
Which of the following findings should the nurse expect?
Fetal heart rate of 150/min with moderate variability.
Painless vaginal bleeding.
Soft abdomen.
Heart rate 120/min.
The Correct Answer is D
Choice A rationale
A fetal heart rate (FHR) of 150/min with moderate variability is within the normal range (110-160/min) and suggests adequate fetal oxygenation, which is less indicative of a significant Grade 2 abruption. A Grade 2 (moderate) abruption typically involves 20%-50% placental separation, often resulting in fetal distress like persistent late decelerations or tachycardia as a compensatory response to hypoxemia.
Choice B rationale
Placenta previa, not abruption, classically presents with painless, bright red vaginal bleeding due to the placenta covering the cervical os. Placental abruption, caused by premature separation of the placenta from the uterine wall, typically causes bleeding accompanied by significant, severe, and unrelenting abdominal pain due to concealed hemorrhage and uterine irritability.
Choice C rationale
A soft abdomen suggests a relaxed uterus, which is normal. In Grade 2 placental abruption, blood often becomes trapped between the placenta and uterine wall, causing uterine tetany or hypertonicity (increased muscle tone) and rigidity, which presents as a firm or board-like abdomen that is tender to palpation.
Choice D rationale
A heart rate of 120/min (tachycardia) in the client is an expected finding in a moderate (Grade 2) placental abruption. The client is experiencing hypovolemia due to hemorrhage (internal and/or external bleeding), which triggers a compensatory sympathetic nervous system response, increasing the heart rate to maintain cardiac output and tissue perfusion.

Correct Answer is A
Explanation
Choice A rationale
The umbilical cord stump typically dries, shrivels, and spontaneously separates from the infant's abdomen due to a process similar to dry gangrene (ischemic necrosis) within one to three weeks after birth; therefore, this statement indicates correct understanding of the normal timeline for cord care and healing.
Choice B rationale
A newborn's skin is sensitive and prone to drying, and daily tub baths are unnecessary and may cause skin irritation; sponge baths are used until the cord stump falls off, and then typically only two to three baths per week are recommended initially to maintain skin integrity.
Choice C rationale
The correct procedure for using a bulb syringe is to compress the bulb before insertion into the mouth (or nose) to create the negative pressure, then release the compression slowly to suction mucus; compressing it after insertion would expel air into the baby's mouth instead of suctioning.
Choice D rationale
Placing a baby on their side to sleep increases the risk of the baby rolling onto their stomach, which is associated with an elevated risk of Sudden Infant Death Syndrome (SIDS); the universally recommended safe sleep position is supine (on the back).
Correct Answer is ["0.25"]
Explanation
Step 1 is: Determine the number of tablets by dividing the prescribed dose by the available dose per tablet. (50 mcg÷ 200 mcg/tablet) = 0.25 tablet. The final calculated answer is 0.25 tablet.
