The practical nurse (PN) is providing discharge instructions to a client who had a partial thyroidectomy. When explaining the actions of the prescribed thyroid supplement levothyroxine sodium, which parameter should the PN tell the client is most important to monitor for potential side effects?

Choice A reason: Recording blood pressures is relevant, as diazepam may cause hypotension, but it is less critical than respiratory monitoring. Status epilepticus requires rapid seizure control, and diazepam’s respiratory depression risk is more immediate, as it can lead to life-threatening hypoxia if not addressed promptly.

Choice B reason: Measuring urinary output monitors renal function but is not urgent in status epilepticus. Diazepam’s primary risk is respiratory depression, not renal effects. Ensuring airway and breathing stability is more critical, as seizures and the drug both threaten respiratory function, making this choice secondary.

Choice C reason: Monitoring respiratory rate and effort is critical, as diazepam, a CNS depressant, can cause respiratory depression, especially in status epilepticus, where seizures already compromise breathing. Hypoventilation risks hypoxia, potentially leading to brain damage or death, making this the most urgent intervention to ensure airway safety.

Choice D reason: Observing eye deviation may indicate ongoing seizures but is less urgent than respiratory monitoring. Diazepam controls seizures, but its side effect of respiratory depression poses an immediate threat. Ensuring adequate ventilation is the priority to prevent hypoxia during acute seizure management.

Choice A reason: Taking a benzodiazepine with morphine is incorrect, as it increases sedation and respiratory depression risk, a dangerous opioid side effect. This indicates misunderstanding, as morphine’s primary management focuses on pain and side effects like constipation, not concurrent sedative use.

Choice B reason: Observing bowel movements and using a stool softener shows understanding, as morphine causes constipation by slowing gastrointestinal motility via opioid receptors. Proactive management with stool softeners prevents complications like impaction, aligning with safe opioid use in cancer pain management.

Choice C reason: Grapefruit juice avoidance is irrelevant to morphine, as it affects drugs metabolized by CYP3A4, not opioids. Morphine is metabolized via glucuronidation, unaffected by grapefruit. This indicates misunderstanding, as it does not address morphine’s key side effects or management.

Choice D reason: Watching for agitation or insomnia is not a primary concern with morphine, which causes sedation. These symptoms may relate to other conditions, but they do not reflect understanding of morphine’s effects, like constipation, making this choice incorrect.
