A nurse is caring for a client who is experiencing postoperative nausea and vomiting. The nurse should monitor the client for which of the following complications of vomiting?

A. To confirm the placement of the NG tube:
Confirming NG tube placement is typically done using other methods, such as auscultation of air insufflation, pH testing, or X-ray. Gastric residual measurement helps assess the status of the stomach content but is not the primary method for confirming tube placement.

B. To determine the client's electrolyte balance:
While the gastric contents do contain electrolytes, the primary purpose of measuring gastric residual is to assess gastric emptying and potential feeding intolerance. It is not the most accurate method for determining overall electrolyte balance.

C. To identify delayed gastric emptying:
This is the correct and primary purpose. Measuring gastric residual helps in identifying if there's a delay in the stomach emptying the previously administered feeding, which can inform the nurse about the client's tolerance to enteral nutrition.

D. To remove gastric acid that might cause dyspepsia:
The process of measuring gastric residual doesn't involve removing gastric acid. It's more about assessing how much of the previously administered feeding remains in the stomach. If there's a high residual volume, it may suggest delayed emptying or feeding intolerance. The focus is on adjusting the feeding plan rather than removing gastric acid.

A. "I will cover the catheter so he cannot see it."
Explanation: This statement suggests attempting to hide the feeding tube from the client. However, addressing the issue of attempting to remove the feeding tube requires a more comprehensive approach, and simply covering the catheter may not address the root cause.

B. "Let me provide more stimulation in his environment."
Explanation: This statement suggests increasing environmental stimulation. While environmental interventions can be considered, it's important to address the specific behavior and assess whether increased stimulation is an appropriate and effective intervention. It may not directly address the issue of attempting to remove the feeding tube.

C. "Let's wait until tonight to see if he continues this behavior."
Explanation: This statement suggests a passive approach of waiting to see if the behavior persists. However, if a client is attempting to remove a feeding tube, it's important to address the issue promptly to prevent potential harm or complications. Waiting may not be the most proactive approach in this situation.

D. "I will call the doctor and get the prescription."
Explanation: This is the most appropriate choice. Applying restraints requires a healthcare provider's order. The nurse should communicate with the doctor to discuss the client's behavior, assess the need for restraints, and obtain the necessary prescription if deemed appropriate. This ensures a lawful and ethical approach to using restraints.
