The primary goal of magnesium sulfate therapy in preeclampsia is to:
A. Lower BP
20
B. Prevent seizures
C. Improve placental blood flow
s
D. Stop preterm labor
am
Answer: B
Rationale: Magnesium sulfate is an anticonvulsant, not an antihypertensive.
Ex
A client on magnesium sulfate has absent reflexes and a respiratory rate of 8. What is the
priority action?
s
A. Increase IV fluids
rt
B. Administer calcium gluconate
pe
C. Lower magnesium dose
D. Monitor O2 saturation
Ex
Answer: B
Rationale: These are signs of magnesium toxicity. Antidote = calcium gluconate.
se
A client with severe preeclampsia is receiving magnesium sulfate. Which finding should the
ur
nurse report to the healthcare provider immediately?
A. Flushing and feeling warm
N
B. Deep tendon reflexes 1+
C. Respiratory rate 10 breaths/min
D. Urine output 40 mL/hr
(
Correct Answer: C. Respiratory rate 10 breaths/min
Rationale: A respiratory rate below 12 is a sign of magnesium toxicity and requires immediate
intervention. Flushing and mild decrease in reflexes are expected side effects urine output
above 30 mL/hr is adequate
,Mallory, a 32-week pregnant client, is admitted with regular contractions, mild back pain, and
increased vaginal discharge. After assessment, the
nurse notes contractions every 4-5 minutes, cervical dilation of 2 cm, and a Category I fetal
heart rate. What is the priority nursing action?
A. Prepare for immediate delivery
B. Begin magnesium sulfate as ordered
C. Encourage ambulation to progress labor
26
D. Administer betamethasone and monitor for side effects
Correct Answer: B. Begin magnesium sulfate as ordered
20
Rationale: The priority is to initiate tocolysis (magnesium sulfate) to delay labor
long enough for corticosteroids (betamethasone) to enhance fetal lung maturity. Immediate
s
delivery is not indicated, and ambulation could worsen preterm labor risk
am
Hyperemesis Gravidarum: Prioritizing Assessment A pregnant client at 10 weeks gestation
presents with severe nausea and vomiting, dry mucous membranes, and reports she has not
Ex
kept any food or fluids down for 48 hours. Which assessment finding would require
immediate intervention?
s
A. Pulse 110 bpm
rt
B. Weight loss of 2 lbs
pe
C. Serum potassium 2.6 mEq/L
D. Mild ketones in urine
Ex
Correct Answer: C. Serum potassium 2.6 mEq/L
Rationale: A potassium level of 2.6 mEq/L is critically low and can lead to life-threatening
cardiac arrhythmias. This requires immediate intervention. Tachycardia, mild weight loss, and
se
ketonuria are expected findings in hyperemesis but are not as immediately dangerous as severe
hypokalemia

,A 29-week pregnant client presents with a sudden gush of fluid Correct Answers:
and is diagnosed with ·Begin continuous fetal monitoring
PPROM. What are the priority nursing interventions? ·Monitor maternal temperature every 4 hours
(Select all that apply.) ·Administer corticosteroids as ordered
·Restrict ambulation
·Begin continuous fetal monitoring
·Monitor maternal temperature every 4 hours Rationale:
·Encourage frequent vaginal exams Continuous fetal monitoring and temperature checks are critical to assess for fetal distress
·Administer corticosteroids as ordered and infection. Corticosteroids promote fetal lung maturity. Vaginal exams
·Restrict ambulation are minimized to reduce infection risk, and ambulation is restricted to decrease the risk
of
cord prolapse
