Final answer:
A client on oxazepam suggesting increased risk of CNS depression to a nurse would be indicating the use of other CNS depressants like alcohol or opiates, or mentioning effects such as heightened sedation or motor impairment, which can signal possible CNS depression or overdose risks.
Step-by-step explanation:
If a client prescribed oxazepam, a type of benzodiazepine, makes a statement indicating concurrent use of other central nervous system (CNS) depressants like alcohol or opiates, or the use of barbiturates, this would suggest to the nurse an increased risk of CNS depression. The combination of these substances can lead to additive effects, significantly increasing the impact on the CNS, potentially causing severe respiratory depression, increased sedation, and possibly leading to overdose.
Furthermore, if the client mentions experiencing effects such as undue sedation, impaired motor and sensory function, or decreased cognitive abilities, these could be signs of CNS depression. The nurse should also be vigilant for any signs of tolerance, dependence, euphoria, and talkativeness, as these could be indicators that the client is at a higher risk of CNS depression or other adverse effects.
