A nurse is assessing a client who has a magnesium level of 4.4 mEq/L. Which of the following findings should the nurse expect?
Hypotension
Tachycardia
Muscle cramps
Hyperreflexia
None
None
The Correct Answer is A
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

Correct Answer is A
Explanation
A.
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.
Correct Answer is C
Explanation
A. Holding the newborn in an en face position: This action promotes bonding between the mother and the newborn and is a positive interaction.
B. Asking the father to change the newborn's diaper: Involving the father in caregiving tasks fosters family involvement and bonding.
C. Viewing the newborn's actions to be uncooperative: This suggests a negative perception of the newborn's behavior, which could indicate potential issues with bonding or misunderstanding
infant cues, requiring the nurse's intervention.
D. Requesting the nurse take the newborn to the nursery so she can rest: While rest is important for the mother, separating the newborn from the mother could disrupt bonding and breastfeeding, so this action should be discussed further with the client to explore other options.
