A nurse is educating a client who has chemotherapy-induced peripheral neuropathy. Which of the following information should the nurse include in the teaching?

Choice A reason: Confusion upon waking is a common and expected side effect of electroconvulsive therapy (ECT). Clients often experience transient disorientation, memory impairment, or headache immediately after the procedure. This occurs because ECT induces a controlled seizure, which temporarily alters brain activity. Nurses must prepare clients for these short-term cognitive effects and reassure them that confusion typically resolves within hours.

Choice B reason: Lorazepam is not administered before ECT because benzodiazepines can raise the seizure threshold and interfere with the therapeutic effect. Instead, clients are given a short-acting anesthetic and a muscle relaxant (commonly methohexital and succinylcholine) to induce unconsciousness and prevent musculoskeletal injury during the seizure. Therefore, this statement is inaccurate.

Choice C reason: ECT does not work by stimulating the vagus nerve. Vagus nerve stimulation (VNS) is a separate treatment modality used for refractory depression and epilepsy. ECT works by inducing a generalized seizure through controlled electrical currents applied to the brain, which alters neurotransmitter activity and improves mood regulation.

Choice D reason: A magnet placed on the scalp is associated with transcranial magnetic stimulation (TMS), not ECT. TMS uses magnetic fields to stimulate specific brain regions without inducing seizures. ECT, in contrast, uses direct electrical currents to trigger a therapeutic seizure. Confusing these modalities can mislead clients, so nurses must clarify the distinction.

Choice A reason: Arterial blood gases are not routinely required before initiating lithium therapy. They are more relevant in respiratory or metabolic disorders, not in baseline monitoring for lithium.

Choice B reason: Total cholesterol is not directly affected by lithium therapy. While metabolic monitoring may be necessary for some psychiatric medications, cholesterol is not a priority baseline test for lithium.

Choice C reason: Thyroid hormones should be evaluated because lithium can interfere with thyroid function, leading to hypothyroidism. Baseline thyroid levels are essential to monitor for potential adverse effects during therapy.

Choice D reason: Hemoglobin levels are not directly impacted by lithium therapy. While general health screening may include hemoglobin, it is not a priority baseline test specific to lithium administration.
