A nurse is reviewing laboratory results of a client. The client's ABG results are as follows: pH 7.2, HCO, 26 mEq/L, PaCO2 52 mm Hg. Which of the following acid-base imbalances should the nurse identify the client is experiencing?

A) Discontinue the overhead trapeze:
The overhead trapeze can be beneficial for the client to assist with repositioning and mobility, especially postoperatively. Removing it would hinder the client's ability to move independently and could increase the risk of complications from immobility.

B) Turn the client every 6 hr while in bed:
Turning the client every 6 hours is insufficient for preventing complications such as pressure ulcers. Standard care involves repositioning the client at least every 2 hours to maintain skin integrity and promote circulation.

C) Remind the client that phantom limb pain does not need treatment:
Phantom limb pain is a real and often distressing condition for many amputees. It requires appropriate treatment and management strategies to ensure the client's comfort and psychological well-being. Dismissing the pain can lead to increased distress and hinder recovery.

D) Assist the client to a prone position every 3 hr:
Positioning the client in a prone position regularly helps prevent contractures, particularly hip flexion contractures, which are common after lower limb amputations. This position can stretch the hip muscles and aid in maintaining proper alignment and mobility, making it a beneficial intervention in postoperative care.

A) Evaluate the client's understanding of diabetes management: While it is important to assess the client’s understanding of diabetes management to prevent future hyperglycemic episodes, this is not the immediate priority. The client's current hyperglycemic-hyperosmolar state needs urgent intervention to stabilize their condition before educational measures can be effective.

B) Administer potassium supplements: Potassium supplementation may be necessary, especially if the client is hypokalemic, but it is not the first action. Electrolyte levels should be monitored and corrected as part of the treatment, but the initial priority is to address the severe dehydration and hyperglycemia.

C) Initiate a continuous infusion of 0.9% sodium chloride: This is the most critical first step. Clients in a hyperglycemic-hyperosmolar state are typically severely dehydrated due to osmotic diuresis. Initiating a continuous infusion of isotonic saline helps to restore intravascular volume, improve perfusion, and stabilize hemodynamics, which is essential before addressing other issues.

D) Check for improvements in the client's level of consciousness: Monitoring the client's level of consciousness is important as it provides information about their neurological status and response to treatment. However, this is a subsequent action after initiating fluid resuscitation, which directly addresses the immediate life-threatening aspects of the hyperglycemic-hyperosmolar state.
