Final answer:
In critical care, a nurse's duties before dialysis include evaluating lab results, potentially administering or withholding antihypertensive medications, assessing dialysis access sites, and weighing the patient to monitor fluid status. These tasks are done under the supervision of a registered nurse to ensure the patient's safe and effective dialysis treatment.
Step-by-step explanation:
When a patient is in the critical care unit and scheduled to receive dialysis, the nurse's responsibilities under the direct supervision of a registered nurse include several key tasks to ensure the safety and efficacy of the dialysis treatment.
- Evaluate morning laboratory results and report any abnormalities. This is critical, as it helps in adjusting the dialysis treatment according to the patient's current metabolic needs.
- Administer the patient's antihypertensive medications only if indicated. Sometimes, these may be withheld just before dialysis to prevent potential complications, such as hypotension, during the procedure.
- Assess the dialysis access site and promptly report any abnormalities. A well-functioning access site is necessary for effective dialysis.
- Weigh the patient to monitor fluid status. Weight changes can indicate fluid losses or gains between dialysis sessions.
- Hold or give all medications based on the provider's orders. Often, certain medications are withheld until after the dialysis session to avoid removal by the dialysis process.
This comprehensive care approach ensures that the patient's treatment is tailored specifically to their needs, optimizing health outcomes and maintaining safety during dialysis.
