Question 1 of 5
Which condition must occur in order for identical (monozygotic) twins to develop?
Correct Answer: C
Rationale: The correct answer is C: One sperm fertilizes one ovum. Identical twins develop from a single fertilized egg that splits into two embryos. This process results in monozygotic twins with identical genetic makeup. If one sperm fertilizes two ova (
A), it would result in fraternal (dizygotic) twins, not identical twins. Two sperm fertilizing two ova (
B) would also produce fraternal twins with different genetic compositions. If two sperm fertilize one ovum (
D), it would lead to chromosomal abnormalities, not identical twins.
Therefore, the only scenario that aligns with the development of identical twins is when one sperm fertilizes one ovum, leading to the formation of monozygotic twins.
Question 2 of 5
The client who is scheduled for a nonstress test (NST) asks the nurse to explain the purpose of the test. Which of the following is the correct response?
Correct Answer: A
Rationale: The correct response is A: The purpose of the NST is to assess the fetal CNS. This is correct because a nonstress test is used to evaluate the fetal well-being by monitoring the fetal heart rate in response to fetal movement. The CNS controls the heart rate, so the test assesses the functionality of the fetal CNS.
Incorrect choices:
B: Gestational age is typically determined through ultrasound or last menstrual period.
C: Fetal lie refers to the position of the fetus in the uterus, which is determined through physical examination or ultrasound.
D: Fetal breathing can be assessed through ultrasound or other specialized tests, not the NST.
In summary, the correct response focuses on the specific purpose of the NST, which is to evaluate the fetal CNS, making it the most appropriate choice among the options provided.
Question 3 of 5
Two hours after delivery the nurse assesses the client and documents that the fundus is soft, boggy, above the level of the umbilicus, and displaced to the right side. The nurse encourages the client to void. Which is the rationale for this nursing action?
Correct Answer: A
Rationale:
Correct Answer: A
Rationale:
1. After delivery, the uterus should be firm and midline to facilitate uterine contractions and prevent excessive bleeding.
2. A soft, boggy uterus may indicate uterine atony, which can lead to postpartum hemorrhage.
3. A full bladder can impede uterine contractions by displacing the uterus and preventing it from contracting effectively.
4. By encouraging the client to void, the nurse helps ensure that the bladder is not obstructing the uterus, promoting proper uterine involution and preventing complications.
Summary of Incorrect
Choices:
B: Overdistended bladder pressing on episiotomy may cause dehiscence, but this is not the primary concern in this scenario.
C: Bladder distention causing urinary stasis and infection is a potential complication, but it is not directly related to uterine contractions.
D: Massaging the fundus can be helpful but addressing the full bladder is a priority
Question 4 of 5
An 8-year-old child is admitted to a pediatric unit with a fractured femur and is placed in skeletal traction. Which of the following nursing interventions is the most appropriate?
Correct Answer: C
Rationale: The correct answer is C: Compare pulses on affected site to contralateral side. This is the most appropriate nursing intervention because it helps in assessing the circulation and perfusion to the affected limb. By comparing pulses on the affected side to the contralateral side, the nurse can detect any potential circulation issues or complications related to the traction. Positioning the weights securely is important but not as critical as monitoring pulses. Providing high-fat meals and diversional activities are not directly related to the immediate care of a fractured femur in traction.
Question 5 of 5
A 6-year-old child is brought to the emergency department after falling down the outdoor steps. The parent's account of the incident appears different than the neighbor's account of the incident. Upon questioning the child, the nurse should recognize which of the following as usual pattern of behavior exhibited by an abused child?
Correct Answer: B
Rationale: Abused children often repeat their parents' stories to avoid implicating them.
