,NU 170 Exam 3 | Maternal-Child Nursing | Advanced Study Guide 2026/2027 UPDATE – Galen
1. A nurse is caring for a client with severe preeclampsia receiving intravenous magnesium
sulfate. Which assessment finding should the nurse prioritize as a sign of magnesium toxicity?
A. Respiratory rate of 10 breaths per minute
B. Blood pressure of 150/95 mmHg
C. Presence of +2 deep tendon reflexes
D. Increased urine output of 50 mL/hr
Answer: A
Rationale: Magnesium sulfate toxicity is characterized by respiratory depression (less
than 12/min), loss of deep tendon reflexes, and decreased urinary output. A respiratory
rate of 10 is the most critical priority.
2. A 28-week gestation client presents with painless, bright red vaginal bleeding. Which
diagnostic procedure should the nurse anticipate being contraindicated?
A. Transabdominal ultrasound
B. Vaginal examination
C. Fetal heart rate monitoring
D. Hemoglobin and hematocrit levels

Rationale: Painless bright red bleeding is indicative of placenta previa. Manual vaginal
exams are strictly contraindicated until placenta previa is ruled out, as it can cause massive
hemorrhage.
3. Which clinical manifestation is specifically associated with Abruptio Placentae rather than
Placenta Previa?
A. Painless vaginal bleeding
B. Board-like, rigid abdomen
C. Soft, non-tender uterus
D. Fetal heart rate within normal limits
Answer: B
Rationale: Abruptio placentae is characterized by painful vaginal bleeding, uterine
tenderness, and a rigid, board-like abdomen due to concealed or overt hemorrhage within
the uterine wall.
4. A postpartum client is experiencing heavy vaginal bleeding and a boggy fundus. What is the
priority nursing action?
A. Administer oxygen via non-rebreather mask
B. Perform fundal massage
