The registered nurse is assessing a 62-year-old female client who is receiving intravenous hydromorphone via a patient-controlled analgesia (PCA) pump after major abdominal surgery. The nurse finds the client somnolent, falling asleep mid-sentence during the assessment, and difficult to arouse. When stimulated, the client states, "My pain is still an 8 out of 10," and reaches for the demand button. The client's vital signs are: blood pressure 104/62 mm Hg, heart rate 64 beats/minute, respiratory rate 9 breaths/minute, and SpO2 91% on room air.

Which action should the nurse take first?

  1. Obtain a venous blood gas sample to evaluate the partial pressure of carbon dioxide (PCO2).
  2. Hold the PCA pump immediately, stimulate the client to take deep breaths, and closely monitor sedation.
  3. Administer a nonsteroidal anti-inflammatory drug (NSAID) as an adjunct to help lower the pain score.
  4. Encourage the client to press the PCA demand button to achieve adequate comfort.
