Nursing NUR304 Lecture Notes - Lecture 6: Antiemetic, Vestibular System, Intracranial Pressure
Document Summary
Nausea & vomiting can be caused by a variety of conditions such as infections, drugs, motion, organic disease or psychological factors. The underlying cause of the symptoms must be elicited before emesis is corrected. The vomiting center in the medulla responds to stimulation from many peripheral areas as well as stimuli from cns itself, the ctz in the medulla, the vestibular apparatus of the ear & the cerebral cortex. Because of their antiemetic and antinauseant action the antiemetics may mask overdose caused by other drugs. 1- take a complete history, if it is unusual occurance or if it is a recurring phenomenon. 2- assess for other untoward symptoms as increased intracranial pressure or intestinal obstruction (antiemetic may mask signs of underlying pathology) 3- caution the client that drug tends to cause drowsiness & dizziness, advise him\her to avoid hazardous tasks.
