A nurse is teaching the guardian of an infant who has developmental dysplasia of the hip about a Pavlik harness. Which of the following Instructions should the nurse include?

A.

A. Auscultating the client's left arm for a bruit helps assess the patency and function of the arteriovenous fistula. A bruit indicates normal blood flow through the fistula.

B. Comparing blood pressure in both arms every 2 hours is not specifically related to monitoring the arteriovenous fistula. Blood pressure comparison may be done periodically but is not as directly relevant to postoperative care of the fistula.

C. Instructing the client to keep the left arm in a dependent position may help with venous return but is not the primary action for monitoring the arteriovenous fistula's patency and function.

D. Encouraging the client to restrict movement of the left arm is not necessary unless there are specific instructions from the surgeon. Encouraging gentle movement and range of motion exercises may actually be beneficial for preventing stiffness and promoting healing.

A. A blood glucose level of 120 mg/dL is within the expected range for a client receiving total parenteral nutrition and does not require immediate intervention.

B. A serum sodium level of 138 mEq/L is within the normal range and does not require immediate intervention.

C. An oral temperature of 37.6°C (99.7°F) is slightly elevated but may be within the client's normal range and does not require immediate intervention unless accompanied by other signs of infection.

D. A weight increase of 2 kg (4.4 lb) in the past 24 hours indicates fluid overload, which can lead to complications such as heart failure or pulmonary edema. Immediate intervention, such as adjusting the rate of fluid administration or notifying the healthcare provider, is necessary to prevent further complications.
