An incident report is a tool used to document any unexpected or adverse event that occurs in the healthcare setting. It is important to report incidents to ensure proper investigation, analysis, and implementation of measures to prevent future occurrences.

In this example, the incident involves an error with an electronic IV pump resulting in the delivery of an incorrect amount of fluid, which can have serious implications for the client's safety and well-being.

The other examples listed may require further actions but may not necessarily require an incident report:

1. A nurse discovers that a client's family member has administered a PCA dose: While it is concerning that a client's family member administered a patient-controlled analgesia (PCA) dose, it is more appropriate to address this situation through immediate intervention, education, and communication with the healthcare provider. An incident report may not be necessary unless there are further complications or system issues related to this incident.
2. A nurse observes another nurse remove wrist restraints one at a time from a client who is currently calm: While the observation of improper restraint removal raises concerns about proper restraint protocol, it is more appropriate to address this situation through immediate intervention and communication with the involved nurse and healthcare provider. Depending on the severity of the situation, an incident report may or may not be warranted, but it is not the primary action in this case.
3. A nurse observes a client vomiting after receiving an oral pain medication: While it is important to assess and address the client's condition and any adverse reactions, such as vomiting after receiving medication, it may not necessarily require an incident report. The nurse should assess the client, notify the healthcare provider, and document the incident appropriately in the client's medical record.

Varicella zoster is highly contagious, and airborne precautions should be implemented. Assigning the client to a negative pressure airflow room helps prevent the spread of the virus to others by containing and filtering the air within the room.

In addition to airborne precautions, contact precautions should also be implemented. This includes using gloves and gowns when providing care to the client to minimize direct contact with infectious materials.

The other options listed are not appropriate interventions for a client with varicella zoster: While it is important to minimize close contact with an infectious client, varicella zoster is primarily transmitted through airborne droplets. Visitors should follow the appropriate precautions, such as wearing masks and adhering to hand hygiene, rather than just maintaining a certain distance.

Aspirin should not be given to clients with varicella zoster, especially children, due to the risk of developing Reye's syndrome. Reye's syndrome is a rare but serious condition that can cause swelling in the liver and brain. Acetaminophen (paracetamol) is typically recommended for managing fever in clients with varicella zoster.
