A nurse is caring for a patient who is receiving DSW with 20 mEq of KCL at 75 mL/hr. The provider has prescribed 1 g of ceftriaxone IV. When preparing to administer this medication by IV piggyback, which of the following data is the highest priority for the nurse to consider before administration?

B. This is the highest priority. Before administering ceftriaxone via IV piggyback, the nurse must ensure compatibility with the primary IV solution (D5W with KCl). Certain medications can interact chemically or physically with other IV solutions or medications, leading to precipitation, inactivation, or other adverse effects. Compatibility should be verified through appropriate resources or pharmacy guidelines.

A. Vital signs provide crucial information about the patient's overall condition, but they do not directly impact the administration of the IV medication ceftriaxone. However, if there are significant changes in vital signs (e.g., fever, hypotension), these could influence the decision to administer ceftriaxone or any medication.

C. Important, but not directly related to medication administration. The patient's level of consciousness is crucial for assessing their neurological status and response to treatment, but it does not affect the administration of ceftriaxone IV piggyback specifically.

D. Important, but not the highest priority in this context. Monitoring the amount of IV solution in the primary bag is essential to ensure continuous fluid delivery and prevent interruptions in therapy.

However, for the immediate preparation and administration of ceftriaxone IV piggyback, ensuring compatibility with the primary IV solution takes precedence.
