सही उत्तर: क) Loss of the patellar (knee) reflex
Patellar reflexes disappear at about 8-10 mEq/L, before respiratory depression (about 12 mEq/L) and cardiac arrest at higher levels. So reflexes, respiratory rate and urine output are monitored before each dose.

Which antihypertensive is contraindicated in pregnancy?
