Answer to Question 1

ANS: B, D, E
Signs of magnesium toxicity include the following:
 Respiratory rate of less than 12 breaths/min (hospitals may specify a rate < 14 breaths/min)
 Maternal pulse oximeter reading lower than 95
 Absence of deep tendon reflexes
 Sweating, flushing
 Altered sensorium (confused, lethargic, slurred speech, drowsy, disoriented)
 Hypotension
 Serum magnesium value above the therapeutic range of 4 to 8 mg/dL
Cold, clammy skin and a pulse oximeter reading of 95 would not be signs of toxicity.

Answer to Question 2

ANS: C
A 10 solution contains 10 g in 100 mL.
X minutes = 1 minute  100 mL  1 g = 10 minutes
1 mL 10 g
