Final answer:
The nurse should administer Flumazenil to the client receiving moderate (conscious) sedation with midazolam in order to reverse the effects of the sedative and restore normal breathing.
Step-by-step explanation:
The nurse should administer Flumazenil to the client receiving moderate (conscious) sedation with midazolam.
Flumazenil is a medication used to reverse the effects of benzodiazepines, such as midazolam. It works by blocking the receptors that benzodiazepines bind to, thereby reversing their sedative effects.
In this case, the client's decreased respiratory rate and decreased oxygen saturation indicate that the sedative effect of midazolam is too strong, and Flumazenil can help reverse this effect and restore normal breathing.
