Which patient factor increases risk with a PCA basal rate: opioid-naïve status or opioid tolerance?
Which patient factor increases risk with a PCA basal rate: opioid-naïve status or opioid tolerance?
Tap to reveal answer
Opioid-naïve status. Opioid-naïve patients lack tolerance, making them more susceptible to respiratory depression from continuous basal infusions.

What is the PCA “basal rate” setting?
What is the PCA “basal rate” setting?
Tap to reveal answer
Continuous background opioid infusion. A basal rate provides a steady low-dose opioid delivery to maintain analgesia, supplementing patient-initiated boluses.

What does the PCA “lockout interval” prevent?
What does the PCA “lockout interval” prevent?
Tap to reveal answer
Repeat dosing within a set time to limit overdose risk. The lockout interval enforces a minimum time between doses, safeguarding against excessive opioid accumulation and resultant toxicity.

Which device should be used to detect hypoventilation earlier than pulse oximetry in PCA patients?
Which device should be used to detect hypoventilation earlier than pulse oximetry in PCA patients?
Tap to reveal answer
Capnography (end-tidal $CO_2$ monitoring). Capnography measures exhaled carbon dioxide levels, identifying hypoventilation sooner than pulse oximetry, which may remain normal until severe hypoxia develops.

Which parameter is most important to trend for PCA opioid safety: pain score or sedation level?
Which parameter is most important to trend for PCA opioid safety: pain score or sedation level?
Tap to reveal answer
Sedation level. Trending sedation provides earlier detection of opioid-induced central nervous system depression compared to pain scores, which may not correlate with safety risks.

Which monitoring finding is the most concerning early sign of opioid-induced respiratory depression on PCA?

Decreased respiratory rate. Opioids primarily depress the respiratory center, making bradypnea an early indicator of potential life-threatening hypoventilation.

Tap to reveal answer
PCA by proxy. This term describes unauthorized activation by non-patients, which bypasses the safety mechanism of patient-controlled dosing and increases overdose risk.

Tap to reveal answer
Self-titration reduces oversedation risk when used correctly. Patient self-administration allows for precise dosing based on real-time pain needs, minimizing the risk of excessive opioid accumulation from delayed nurse responses.

Decreased $RR$. Opioids cause respiratory depression, whereas uncontrolled pain typically elevates blood pressure through sympathetic activation.

Which patient statement requires immediate correction: “My spouse can press it while I sleep” or “Only I press it”?
Tap to reveal answer
“My spouse can press it while I sleep.”. This statement promotes PCA by proxy, which circumvents safety features and risks oversedation since the patient may not be alert enough to self-dose.

Press the button at onset of pain; do not wait until severe. Early activation maintains steady analgesia levels, preventing pain escalation that requires higher doses and increases side effect risks.
