This problem will have 4 answers. The physician orders Ancef 400mg IV every 8 hours for a child weighing 44 lbs. You have on hand Ancef 330 mg/mL. The recommended daily IV dosage for a child is 75 mg/kg/day.

1. What is the child's weight in kg? 

a) Compare the total intake and output of fluids for the 24 hours: To assess fluid balance and status, the nurse must compare the intake and output of fluids. This helps to determine whether the patient is retaining or losing fluids.

b) Compare the patient's intake with the normal range of adult fluid intake: While this is useful for understanding general fluid needs, it does not directly assess the patient's fluid status. The comparison should be between intake and output.

c) Ensure the information is included in the verbal end-of-shift report: While this is good practice, the focus should be on using the information to assess the patient's fluid balance.

d) Report the exact milliliter of intake to the physician's office nurse: The exact intake should be recorded in the patient's chart and used for clinical decision-making, but it does not need to be reported to a physician's office nurse unless specified.

a) Respiratory Decompression: "Respiratory Decompression" is not a term used in ABG interpretation.

b) Respiratory Alkalosis: Respiratory alkalosis is characterized by a pH greater than 7.45 and a PaCO2 less than 35 mm Hg. In this case, the pH is low (7.31), and the PaCO2 is elevated, which is not consistent with respiratory alkalosis.

c) Respiratory PH: "Respiratory PH" is not a proper ABG term.

d) Respiratory Acidosis: The pH is 7.31, which is acidotic (normal range is 7.35-7.45). The PaCO2 is 50 mm Hg (elevated), indicating that the cause of the acidosis is respiratory in nature, as the kidneys have not yet compensated with HCO3 (bicarbonate).
