NURS 306 Final Quiz V3 | NURS 306 OB |
Actual Q&A with Rationale (NURS306
Final Quiz) | West Coast University
1. A nurse is calculating a client’s expected date of delivery using Naegele’s rule. The client’s
last menstrual period began on October 10. What is the correct EDD?
A. January 17
B. July 10
C. July 17
D. August 10
Answer: C
Rationale: To use Naegele’s rule, the nurse subtracts 3 months and adds 7 days to the first
day of the last menstrual period. For October 10, subtracting 3 months leads to July, and
adding 7 days results in July 17. This calculation assumes a standard 28-day menstrual
cycle.
2. A nurse is caring for a client who is in the first stage of labor and has an umbilical cord
prolapse. Which of the following actions should the nurse take first?
A. Cover the cord with sterile saline-soaked gauze
B. Prepare for an emergency cesarean birth
C. Place the client in a high-Fowler’s position
,D. Apply upward pressure to the presenting part with a sterile gloved hand
Answer: D
Rationale: Applying upward pressure to the presenting part relieves compression on the
umbilical cord, which is the immediate priority to maintain fetal oxygenation. Following
this, the nurse should place the client in a Trendelenburg or knee-chest position.
Immediate delivery via cesarean section is typically necessary after stabilizing the cord.
3. A client at 34 weeks of gestation presents with painless, bright red vaginal bleeding. Which
condition should the nurse suspect?
A. Placental abruption
B. Cervical insufficiency
C. Placenta previa
D. Preterm labor
Answer: C
Rationale: Placenta previa is classically characterized by the onset of painless, bright red
vaginal bleeding during the third trimester. This occurs because the placenta is implanted
over or near the cervical os. In contrast, placental abruption usually involves painful, dark
red bleeding and a board-like abdomen.
4. A nurse is monitoring a fetal heart rate (FHR) tracing and notes early decelerations. Which
of the following is the most likely cause of this finding?
A. Uteroplacental insufficiency
, B. Fetal head compression
C. Umbilical cord compression
D. Fetal hypoxia
Answer: B
Rationale: Early decelerations are caused by fetal head compression during contractions
and are generally considered a benign finding. The deceleration usually mirrors the
contraction, beginning and ending at the same time. No specific nursing intervention is
required other than continued observation.
5. A nurse is reviewing the laboratory results of a client who is at 32 weeks of gestation and
has preeclampsia. Which of the following findings is indicative of HELLP syndrome?
A. Elevated liver enzymes (AST/ALT)
B. Elevated hemoglobin
C. Increased platelet count
D. Decreased creatinine levels
Answer: A
Rationale: HELLP syndrome stands for Hemolysis, Elevated Liver enzymes, and Low
Platelets. Elevated AST and ALT levels indicate hepatic involvement and damage due to the
disease process. The nurse should also monitor for a drop in hematocrit and a platelet
count below 100,000/mm3.
