Maternal Newborn ATI Proctored Exam

Correct Answer: D

Rationale: Calcium gluconate is the antidote for magnesium sulfate toxicity. In cases of magnesium sulfate toxicity, calcium gluconate is administered to counteract the effects of magnesium and restore calcium levels. Magnesium toxicity can lead to symptoms such as muscle weakness, respiratory depression, and cardiac arrhythmias. Calcium gluconate helps in reversing these effects by competing with magnesium and preventing its adverse manifestations. Nifedipine is a calcium channel blocker used for conditions like hypertension and angina, not for magnesium toxicity. Pyridoxine is vitamin B6 and is not the antidote for magnesium toxicity. Ferrous sulfate is an iron supplement and is not used to treat magnesium sulfate toxicity.

Correct Answer: A

Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.

Correct Answer: C

Rationale: The correct answer is C. Taking iron supplements with orange juice, which contains vitamin C, enhances the absorption of iron, making the treatment more effective. Choices A, B, and D are incorrect because taking ferrous sulfate with milk, calcium-rich foods, or breakfast may hinder iron absorption due to interactions with calcium or other substances that compete with iron absorption.

Correct Answer: A

Rationale: During early pregnancy, nausea and vomiting in the morning are common symptoms. Eating crackers or plain toast before getting out of bed can help manage morning nausea by stabilizing blood sugar levels. This simple and easily digestible snack can alleviate symptoms by providing some sustenance to the stomach before fully waking up and moving around. Choices B, C, and D are incorrect. Waking up during the night to eat a snack may disrupt sleep patterns, skipping breakfast can worsen symptoms by allowing the stomach to remain empty for longer periods, and eating a large evening meal may exacerbate morning nausea due to increased stomach contents.

Correct Answer: A

Rationale: In this scenario, the correct answer is "Oligohydramnios". Oligohydramnios, which refers to low amniotic fluid volume, may necessitate amnioinfusion to address the deficiency. Fetal cord compression is another indication for amnioinfusion as it can help alleviate pressure on the umbilical cord. Hydramnios or polyhydramnios, conversely, involve an excess of amniotic fluid and do not typically require amnioinfusion. Therefore, choices B, C, and D are incorrect in this context.
