A nurse is reviewing the ABG values of a client. The client has a pH of 7.2, PaCO2 of 60 mm Hg, and HCO3 of 25 mEq/L. The nurse should identify that the client has which of the following acid-base imbalances?

A. Instructing a staff member to maintain a log of emergency care provided is not the first action that the nurse should take. This is an important task, but it can be done later, after ensuring the safety of the staff and children and providing immediate care to those who need it.

B. Applying cervical spine collars to children who have suspected neck trauma is not the first action that the nurse should take. This is a priority intervention, but it can only be done after surveying the scene for potential hazards and making sure that it is safe to approach and touch the children.

C. Notifying guardians of the emergency and injuries to their children is not the first action that the nurse should take. This is a necessary step, but it can be delegated to another staff member or done after providing initial care to the children.

D. Surveying the scene for potential hazards to staff and children is the correct answer. This is the first action that the nurse should take, according to the principles of emergency care. The nurse needs to assess the situation and ensure that there are no dangers such as fire, electricity, gas, or falling debris that could harm anyone at the scene. The nurse also needs to determine how many children are injured, how severe their injuries are, and what resources are available to help them.

A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.

B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.

C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.

D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.
