A nurse is collecting data from a client who is receiving magnesium sulfate via continuous IV infusion to treat preeclampsia. Which of the following findings indicates that the medication is having a therapeutic effect?

A. Measure the duration of the seizure. This is the correct action. Monitoring the duration of the seizure is important for assessing its severity and deciding when to intervene medically. A seizure lasting longer than 5 minutes requires immediate intervention.

B. Lower the side rails of the bed when the seizure begins. This is not recommended. The side rails should be raised to protect the client from injury. Lowering them could increase the risk of falling out of bed.

C. Insert an oral airway into the client's mouth. This is incorrect. Inserting an airway into the mouth during a seizure can be dangerous and may result in injury to the client or the nurse. The client’s airway should be kept clear, but inserting an object into the mouth is not recommended.

D. Restrain the client's arms and legs to prevent injury. This is incorrect. Restraining the client during a seizure can cause injury to both the client and the nurse. It is better to allow the seizure to proceed naturally while ensuring the client is protected from injury (e.g., by placing a soft pillow under their head or cushioning hard surfaces around them).

A. Administering a subcutaneous insulin injection requires nursing knowledge and skill to ensure correct dosage, technique, and monitoring for side effects. This should not be delegated to an assistive personnel (AP).

B. Removing an NG tube requires nursing assessment to determine if removal is appropriate and safe for the client. It also requires skill in managing complications that may arise. This should not be delegated to an AP.

C. Providing discharge teaching about home IV medication therapy is a complex task that requires nursing knowledge about medication management, potential complications, and instructions for safe administration. It cannot be delegated to an AP.

D. Collecting a sputum culture can be delegated to an AP. This is a task within their scope of practice, provided the AP has been trained in collecting samples and the procedure is straightforward.
