A nurse is caring for a client who has ulcerative colitis and is receiving sulfasalazine. Which of the following findings requires immediate intervention?

A. "Instruct the client's visitors not to operate the PCA pump.” Only the client should press the PCA button to self-administer medication. Allowing visitors or family members to press the button ("PCA by proxy") increases the risk of over-sedation, respiratory depression, and opioid toxicity. The nurse should reinforce to visitors that only the client should control medication delivery based on their own pain level.

B. "Check the client's pain level every 8 hours." Pain assessment should be performed more frequently than every 8 hours when a client is receiving morphine PCA. Pain, sedation level, and respiratory status should be monitored every 1–2 hours initially and then at regular intervals as determined by hospital protocol to ensure effective pain management and prevent complications such as respiratory depression.

C. "Diarrhea is an adverse effect of morphine PCA." Morphine is an opioid analgesic that commonly causes constipation, not diarrhea. Opioids slow gastric motility, which can lead to delayed bowel movements, bloating, and discomfort. Clients on long-term opioid therapy often require stool softeners or laxatives to prevent opioid-induced constipation.

D. "Using morphine PCA increases the client's risk of toxicity." PCA pumps are designed with preset dose limits and lockout intervals to prevent overdose. While there is a risk of opioid toxicity if the system is misused (e.g., PCA by proxy or improper settings), PCA is actually safer than traditional opioid administration methods because it allows for precise dosing and patient-controlled pain management. Proper monitoring helps prevent complications.

A. Assist the client to a left lateral position. The preferred position for vaginal suppository insertion is the dorsal recumbent (lying on the back with knees bent) or the lithotomy position. The left lateral position is typically used for rectal suppository administration, not vaginal medication insertion.

B. Insert the suppository along the posterior wall of the vaginal canal. The suppository should be inserted along the posterior vaginal wall, as this allows for proper absorption and helps ensure the medication remains in place. The client should be advised to lie down for at least 10-15 minutes after insertion to prevent the suppository from slipping out.

C. Apply a light coating of petroleum jelly to the suppository. Petroleum jelly should never be used as it can interfere with medication absorption and may break down the suppository. If lubrication is needed, a small amount of water-soluble lubricant (e.g., KY Jelly) can be applied to facilitate insertion.

D. Put on sterile gloves before handling the suppository. Clean gloves (not sterile gloves) are sufficient for vaginal suppository administration. The vaginal canal is not a sterile environment, so strict aseptic technique is not required. However, proper hand hygiene and glove use are essential to prevent contamination and infection.
