Actual Q&A with Rationale (NURS306
Final Quiz) | West Coast University
1. A nurse is caring for a client who is at 34 weeks of gestation and has a prescription for
magnesium sulfate. Which of the following findings should the nurse identify as a priority to
report to the provider?
A. Flushing or a feeling of warmth
B. Deep tendon reflexes of 2+
C. Respiratory rate of 10/min
D. Sedation or drowsiness
Answer: C
Rationale: Magnesium sulfate toxicity is a critical concern that the nurse must monitor for
continuously during administration. A respiratory rate below 12/min is a primary
indicator of toxicity and requires immediate cessation of the infusion and notification of the
provider. The nurse should also have calcium gluconate readily available as the antidote to
reverse these life-threatening effects.
2. A client is in the first stage of labor and the nurse notes late decelerations on the fetal
heart rate monitor. Which of the following actions should the nurse take first?
A. Increase the IV fluid rate
,B. Reposition the client to a lateral position
C. Apply oxygen via nonrebreather mask
D. Perform a vaginal examination
Answer: B
Rationale: Late decelerations are indicative of uteroplacental insufficiency, which poses a
risk for fetal hypoxia. Turning the patient to the side is the initial priority because it
relieves pressure on the inferior vena cava and improves placental perfusion. After
repositioning, the nurse should follow up with other intrauterine resuscitation measures
like oxygen administration and fluid boluses.
3. Using Naegele’s rule, what is the estimated date of delivery (EDD) for a client whose last
menstrual period began on March 15?
A. December 22
B. December 8
C. January 22
D. December 15
Answer: A
Rationale: Naegele’s Rule is a standardized method used to estimate the delivery date by
calculating from the first day of the last menstrual period. The formula requires subtracting
, 3 months and adding 7 days and 1 year to the start of the LMP. In this case, March 15 minus
3 months is December 15, and adding 7 days results in December 22.
4. A nurse is assessing a postpartum client 2 hours after delivery and notes the fundus is
boggy and displaced to the right. Which of the following is the priority nursing action?
A. Massage the fundus until firm
B. Administer oxytocin as prescribed
C. Assist the client to the bathroom to void
D. Assess the amount of lochia
Answer: C
Rationale: A fundus that is displaced to the right or left usually indicates a distended
bladder, which prevents the uterus from contracting effectively. Assisting the patient to
empty their bladder will allow the uterus to return to the midline and firm up. If the fundus
remains boggy after voiding, then fundal massage and medication may be indicated.
5. A nurse is teaching a client who is pregnant about a nonstress test (NST). Which of the
following statements by the client indicates an understanding of the procedure?
A. I will need to be NPO for 4 hours before the test
B. I should press the button when I feel the baby move
C. The test will take about 2 hours to complete
D. This test measures the baby’s lung maturity
