Correct Answer is A

Explanation

A. Early decelerations are typically benign and occur in response to head compression during contractions. They mirror the uterine contractions and are not associated with fetal distress.

B. Fetal hypoxia is associated with variable or late decelerations, not early decelerations.

C. Abruptio placentae is a medical emergency characterized by premature separation of the placenta from the uterine wall, which can lead to late decelerations due to fetal hypoxia.

D. Postmaturity is a term used to describe a pregnancy that extends beyond 42 weeks gestation and is not directly related to fetal heart rate patterns during labor.

A. Hypotension B. Tachycardia C. Muscle cramps D. Hyperreflexia E. None F. None

Correct Answer is A

Explanation

A. Hypotension occurs because hypermagnesemia causes vasodilation, which lowers blood pressure. Magnesium acts as a smooth muscle relaxant, decreasing vascular resistance and contributing to hypotension. This is a common clinical finding when magnesium levels exceed the normal range.

B. Tachycardia is not expected with hypermagnesemia. Elevated magnesium levels depress the heart's electrical activity, leading to bradycardia (slow heart rate) instead of tachycardia.

C. Muscle cramps are typically associated with hypomagnesemia, which increases neuromuscular excitability. In hypermagnesemia, neuromuscular function is suppressed, leading to muscle weakness rather than cramps.

D. Hyperreflexia is a symptom of hypomagnesemia, not hypermagnesemia. In hypermagnesemia, neuromuscular activity is depressed, resulting in diminished or absent deep tendon reflexes
