Final answer:
The nurse should review the serum liver enzymes prior to administering the initial dose of a statin medication, as statins can potentially cause liver damage.
Step-by-step explanation:
Prior to administering an initial dose of a statin medication, the nurse should review the serum liver enzymes. Statin medications can potentially cause liver damage, so it is important to assess the patient's liver function before starting the medication. Elevated levels of liver enzymes can indicate liver dysfunction, which may contraindicate the use of statins.
