The parents of a child with acid-base imbalance ask the nurse about mechanisms that regulate acid-base balance. Which statement by the nurse accurately explains the mechanisms regulating acid-base balance in children?

When caring for a child with an open fracture, the nurse should carefully assess for signs and symptoms of infection. An open fracture refers to a fracture where the bone is exposed through the skin, creating a direct pathway for microorganisms to enter and cause infection. Infection is a significant concern in open fractures and can lead to serious complications if not identified and treated promptly. Signs of infection may include increased pain, swelling, redness, warmth, purulent drainage, fever, or systemic signs of infection such as elevated white blood cell count.

Osteoarthritis in (option A) is incorrect because it, is not an immediate concern in the care of a child with an open fracture. Osteoarthritis refers to degenerative joint disease that typically develops over time and is not directly related to the acute management of an open fracture.

epiphyseal disruption in (option B) is incorrect because it, refers to an injury involving the growth plate (epiphyseal plate) that can affect bone growth and development. While it is a potential concern in fractures that involve the growth plate, it is not specific to open fractures and may not be an immediate priority in the initial assessment of an open fracture.

periosteum thickening in (option D) is incorrect because it, may occur in response to injury and fracture healing, but it is not specifically associated with open fractures and is not a primary focus in the initial assessment of an open fracture.

In this scenario, the child's increased urination after a serious motor vehicle crash may
indicate a potential issue with fluid balance. Monitoring the child's intake and output is the
priority action for the nurse. This involves accurately measuring and recording the fluids the
child consumes (intake) and the fluids the child eliminates through urine, sweat, and other
sources (output). By closely monitoring the child's intake and output, the nurse can assess the
child's fluid status and identify any abnormalities or imbalances that may require further
intervention.
Restrict dietary sodium intake in (option A) is incorrect because restricting dietary sodium
intake, may be necessary in certain situations, such as if the child has a known sodium
imbalance or hypertension. However, it is not the priority action in this scenario.
Assess the daily serum sodium level in (option B) is incorrect because assessing the daily
serum sodium level, is important to evaluate the child's electrolyte balance. However, it is not
the priority action compared to monitoring the child's intake and output.

Weigh the child daily in (option C) is incorrect because weighing the child daily, is a useful
measure to assess changes in fluid balance. However, it is not the priority action in this
scenario compared to monitoring the child's intake and output, which provides real-time
information on fluid balance.
