For a patient on a PCA pump who experiences nocturnal pain, what pre-bed dosing instruction should the nurse provide?

• A. Doses every 10 minutes for 30 minutes before bed
• B. Discontinue PCA
• C. Increase basal rate
• D. Switch to oral analgesic

Answer: (A)

Anticipating pain during a long sleep period and keeping relief continuous with the PCA system is the idea here. Giving a pre-bed bolus series uses the PCA’s fast-acting doses to build a protective level of analgesia before the patient is asleep, so pain doesn’t wake them or become hard to treat once they’re resting. This approach leverages the bolus function without relying on the basal rate, which could lead to more medication than needed over time if pain is predictable mostly at night.

Discontinuing PCA would remove the precise, rapid relief tools the patient has, and switching to an oral analgesic may not provide quick enough or reliable relief during sleep. Increasing the basal rate isn't the best choice for nocturnal pain, because it raises the overall, continuous amount of drug and can increase the risk of oversedation or respiratory depression without specifically addressing a nighttime pain spike.
