A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?

A. Drowsiness:
This is the correct answer. Drowsiness or sedation is a common side effect of paroxetine, which is a selective serotonin reuptake inhibitor (SSRI). Clients should be informed about the potential for drowsiness, especially when initiating the medication or adjusting the dosage.
B. Tinnitus:
Tinnitus (ringing in the ears) is not a common side effect of paroxetine. It is important to monitor for auditory issues with medications, but paroxetine is not typically associated with tinnitus.
C. Peripheral edema:
Peripheral edema is not a common adverse effect of paroxetine. Swelling of the extremities is not typically associated with SSRIs like paroxetine.
D. Alopecia:
Alopecia (hair loss) is not commonly associated with paroxetine. Hair loss is not a typical side effect of SSRIs.

A. Identify the client using two identifiers:
This is the correct answer. Before administering any medication, especially controlled substances, it is crucial to positively identify the client using two identifiers (e.g., name, date of birth, or medical record number). This helps prevent medication errors.
B. Remove the medication from the medication dispensing cabinet:
While removing the medication from the dispensing cabinet is part of the administration process, it should occur after confirming the client's identity to ensure the right medication is being given to the right person.
C. Compare the amount of medication available to the inventory record:
Checking the medication inventory is an important step in overall medication management, but it is not the first action when planning to administer a controlled substance.
D. Document the administration of the medication:
Documentation is an essential part of the medication administration process, but it should occur after the medication has been given, not as the first action.
