, The nursing process provides a systematic approach to the provision of care for the

Nursing Process - ECT -
• Assessment: correct answers o A complete physical examination must be completed
o Assessment of the cardiovascular and pulmonary status as well as lab blood and
urine studies; a skeletal history and x-ray should also be considered
o Consent must be obtained
o ECT is voluntary and that consent may be withdrawn at any time
Nurses may be required to assess: correct answers o The client's mood and level of
interaction with others
o Evidence of suicidal ideation, plan, and means
o Level of anxiety and fears associated with receiving ECT
o Thought and communication patterns
o Baseline memory for short and long term events
o Client and family knowledge of indications for, side effects of, and potential risks
associated with ECT

• Planning/Implementation: correct answers o Approximately 30 min before treatment,
administer the pretreatment medication as prescribed by the physician. The usual order
is for atropine sulfate or glycopyrrolate (Robinul) given IM; either of these meds may be
ordered to decrease secretions (to prevent aspiration) and counteract the effects of
vagal stimulation (bradycardia) induced by ECT
o A muscle relaxant, usually succinylcholine chloride, is given IV to prevent severe
muscle contractions during the seizure, thereby reducing the possibility of fractured or
dislocated bones.
o Because succinylcholine paralyzes respiratory muscles as well, the client is
oxygenated with pure oxygen during and after the treatment, except for the brief interval
of electrical stimulation, until spontaneous respirations return.
o Monitor Pulse, respirations, and BP Q15minutes for the first hour, during which time
the client should remain in bed
o MAINTAIN AIRWAY
