Final answer:
For a patient on a morphine PCA without a basal infusion rate, there is no risk of overdosing as the medication is administered only at the patient's request. The PCA pump is designed to prevent overdose, and healthcare professionals monitor the dosage closely. Reassuring the patient and educating them on the proper use of the PCA pump can alleviate their fear.
Step-by-step explanation:
If the patient is on a morphine Patient-Controlled Analgesia (PCA) without a basal infusion rate, there is no risk of overdosing as the medication is administered only at the patient's request. The PCA pump allows the patient to self-administer a predetermined dose of morphine by pressing a button. The PCA pump is programmed to deliver a specific dose of morphine each time the button is pressed, with a lockout period to prevent excessive dosing.
To address the patient's fear of overdosing, reassure them that the PCA pump is designed to prevent overdose and that healthcare professionals monitor the dosage closely. Educate the patient on how to use the PCA pump properly, including the functionality of the lockout feature. It may also be helpful to explain the signs and symptoms of overdose and the importance of reporting any concerns to the healthcare team.
