A nurse is assessing a client who has placenta previa and is receiving fetal monitoring.
Which of the following clinical findings should the nurse expect?
Variable decelerations.
Painless vaginal bleeding.
Rigid abdomen.
Uterine tachysystole.
The Correct Answer is B
Choice A rationale
Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause
variable decelerations on fetal monitoring.
Choice B rationale
Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates
or effaces.
Choice C rationale
A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in
placenta previa.
Choice D rationale
Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use
or other uterine stimulants.

Correct Answer is A
Explanation
Choice A rationale
A respiratory rate of 12/min indicates that the respiratory depression caused by magnesium sulfate toxicity has been effectively reversed by calcium gluconate. Normal respiratory rate in adults is 12-20 breaths per minute.
Choice B rationale
Absent deep tendon reflexes indicate ongoing magnesium sulfate toxicity. Calcium gluconate administration should restore normal reflexes, not cause their absence.
Choice C rationale
Slurred speech is a sign of magnesium sulfate toxicity. Effective treatment with calcium gluconate should improve neurological function and resolve symptoms like slurred speech.
Choice D rationale
A urine output of 22 mL/hr is below the normal range and suggests renal impairment or ongoing toxicity. Effective treatment should result in an increase in urine output to within the normal range (greater than 30 mL/hr).
Correct Answer is A
Explanation
Choice A rationale
Fetal heart rate (FHR) accelerations with fetal movement are a sign of a healthy and reactive nonstress test. This indicates that the fetus is well-oxygenated and there is no immediate distress.
Choice B rationale
Late decelerations of the FHR occur with contractions and are a concern for fetal hypoxia. This does not indicate a reactive nonstress test and instead suggests the need for further evaluation.
Choice C rationale
Variable decelerations are abrupt decreases in FHR and could indicate umbilical cord compression. This does not correlate with a reactive nonstress test.
Choice D rationale
FHR pattern with minimal variability can be a sign of fetal distress or compromised oxygenation. It is not indicative of a reactive nonstress test.
