A client with possible acute kidney injury (AKI) is admitted to the hospital and mannitol is prescribed as a fluid challenge. Prior to carrying out this prescription, what intervention should the nurse implement?
A.
No specific nursing action is required.
B.
Collect a clean catch urine specimen.
C.
Instruct the client to empty the bladder.
D.
Obtain vital signs and breath sounds.
The correct answer and Explanation is :
The correct answer is: D. Obtain vital signs and breath sounds.
Explanation:
Before administering mannitol as a fluid challenge to a client with possible acute kidney injury (AKI), it is crucial for the nurse to obtain baseline vital signs and assess breath sounds. Here’s why this intervention is important:
- Monitoring Vital Signs:
- Blood Pressure and Heart Rate: Mannitol can influence fluid balance and blood pressure. It is essential to have a baseline measurement of the client’s blood pressure and heart rate to monitor for any significant changes or adverse reactions following administration. Mannitol can cause changes in blood volume and blood pressure, so close monitoring is necessary to detect hypotension or any other complications.
- Temperature: While not directly affected by mannitol, monitoring temperature helps in overall assessment and in identifying potential infections or inflammatory responses.
- Assessing Breath Sounds:
- Mannitol acts as an osmotic diuretic, promoting diuresis and potentially impacting fluid balance. The nurse should listen for any signs of pulmonary edema or fluid overload in the lungs. This assessment helps ensure that the client is not developing complications related to fluid shifts or retention.
Other Interventions:
- Collecting a Clean Catch Urine Specimen: While important for diagnostic purposes, it is not the immediate priority before administering mannitol. However, monitoring urine output and characteristics is essential after administration to evaluate the effectiveness of the treatment.
- Instructing the Client to Empty the Bladder: This is more relevant for collecting urine samples or preventing discomfort. It is not directly related to the immediate safety or monitoring concerns before administering mannitol.
In summary, obtaining vital signs and assessing breath sounds ensures that the nurse has a baseline for comparison and can detect any adverse reactions or complications early. This step is integral to safely administering mannitol and managing the client’s condition effectively.
