The nurse is continuing to care for the client in the emergency department (ED). Exhibits The nurse should monitor the client for which of the following based on the result of the client's laboratory test? Select all that apply.

Rationale for correct choices: Amnesia: GHB is known to cause memory loss or amnesia, particularly retrograde amnesia, which makes the client unable to recall events that occurred during intoxication. This is a common effect of GHB when it is used as a "date rape drug." Nausea and vomiting: GHB can cause gastrointestinal symptoms, including nausea and vomiting. This is a well-known side effect, especially when the drug is ingested in larger quantities or in combination with alcohol. Respiratory depression: One of the most concerning effects of GHB is respiratory depression. This can be life-threatening, as GHB has a sedative effect on the central nervous system, potentially leading to slow or shallow breathing and, in extreme cases, respiratory failure. Rationale for incorrect choices: Hyperthermia: GHB typically causes sedation and hypothermia rather than hyperthermia. While stimulant drugs (e.g., methamphetamine) can lead to increased body temperature, GHB is more commonly associated with decreased body temperature. Tachycardia: GHB does not typically cause tachycardia. It is more likely to cause bradycardia (slower heart rate) or maintain normal heart rates due to its sedative effects. Combativeness: GHB is a sedative and CNS depressant, not a stimulant. Therefore, it is unlikely to cause combativeness, which is more typically associated with stimulant drugs like cocaine or methamphetamine.
