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 C
Explanation
Choice A rationale
Feeding from only one breast can lead to engorgement and a decrease in milk supply in the affected breast. It is important to continue breastfeeding from both breasts, even if one is infected.
Choice B rationale
Discarding milk is not necessary and can lead to a decrease in milk supply. The infection does not harm the baby, and breastfeeding helps to drain the breast and clear the infection.
Choice C rationale
Moist heat can help to increase blood flow and promote healing in the affected breast. Applying warm compresses or taking warm showers can help to reduce pain and inflammation associated with mastitis.
Choice D rationale
While staying hydrated is important for overall health, there is no specific requirement to drink at least 1500 milliliters of fluid per day for mastitis. Adequate fluid intake should be maintained, but there is no direct correlation with resolving the infection.
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).
