Causes for hypocalcemia include:
A. Bedrest

C. Presence of Vitamin D (vit D help increase Ca+)
D. Pancreatitis

C. B/p= 78/65D. Negative Trousseau sign
The nurse is caring for a patient with a Mg = 0.8. Which manifestation would correlate with this lab?
A. Nystagmus - eyes get twitchy
B. HR = 45 (would be tachycardic if mag is low)
C. B/p= 78/65 (would be hypertensive if mag is low)
D. Negative Trousseau sign (would be positive if Mag is low)

Why do we give pregnant women magnesium?
TO SLOW CONTRACTIONS the more the mag the slower all muscles contract....the heart slows down...the blood vessels vasodialate...blood pressure drops....
