,NU 170 Final Exam Maternal-Child Nursing (2026) UPDATED – Galen
1. A nurse is caring for a client who is in the first stage of labor and has a fetal heart rate (FHR)
of 140/min with late decelerations. Which of the following is the priority nursing action?
A. Administer oxygen at 8 to 10 L/min via nonrebreather mask
B. Turn the client to a side-lying position
C. Increase the rate of the maintenance IV fluid
D. Document the finding and continue to monitor

action is to improve placental perfusion by positioning the mother on her side. Oxygen
administration and increasing IV fluids are secondary steps.

the nurse report to the provider immediately?
A. A single artery in the umbilical cord

continuous IV infusion. Which of the following findings indicates magnesium toxicity?

B. Deep tendon reflexes 1+
C. Respiratory rate 10/min
D. Urinary output 20 mL/hr

Rationale: Magnesium sulfate is a CNS depressant. Toxicity is indicated by a respiratory
rate less than 12/min, loss of deep tendon reflexes, and urinary output less than 30 mL/hr.
4. Which of the following interventions is appropriate for a child diagnosed with Tetralogy of
Fallot experiencing a ‘tet spell’?
A. Administer high-flow oxygen via a simple mask
