The nurse is caring for a patient who was admitted for a lorazepam (Ativan) overdose. Which assessment finding indicates that the patient is experiencing withdrawal?
a. Lethargy
b. Urine output of 40 mL/hr
c. Heart rate of 48 beats/min
d. Blood pressure of 140/90
D
Elevated blood pressure is consistent with withdrawal from a central nervous system (CNS) de-pressant like lorazepam (Ativan), a benzodiazepine. If an individual has been abusing drugs that depress the CNS and goes through withdrawal, other symptoms would include an elevation in pulse, nervousness, and heightened anxiety. The patient would likely be agitated rather than le-thargic and tachycardic. Urine output of 40 mL/hr is a normal finding.
