The nurse is caring for a client receiving an intravenous medication that is a vesicant. The IV flow has stopped and there is pain, burning and swelling at the IV site. What action should the nurse take first?

B. Tachycardia (elevated heart rate) can be a sign of various underlying conditions, including pain, anxiety, or cardiovascular compromise. While tachycardia may occur as a response to stress or pain associated with the catheter insertion procedure, it can also indicate complications such as hemorrhage, cardiac dysrhythmias, or pulmonary embolism, which require prompt evaluation and intervention.
A. While this can be concerning, it is not typically directly related to complications of a subclavian central venous catheter insertion unless there is evidence of arterial injury or thrombosis.
C. Bibasilar crackles are abnormal lung sounds that can indicate fluid accumulation in the lungs, such as pulmonary edema or pneumonia. However, this may not be directly related to the subclavian central venous catheter insertion itself.
D. Headache is a non-specific symptom that can have numerous causes, including stress, dehydration, or tension.

D. Calling the prescribing physician to clarify the order is the most appropriate action in this situation. Direct communication with the physician allows the nurse to express concerns, seek clarification, and ensure that the medication order is appropriate and safe for the client.
A. Administering a medication at a higher than recommended dose could potentially harm the client and is not in line with safe medication administration practices. It's essential to follow the established guidelines and recommendations for medication dosing to avoid adverse effects or complications.
B. Holding the ordered dose and documenting the rationale is an appropriate initial action. This allows the nurse to pause the administration of the medication, prevent potential harm to the client, and provide a clear record of the decision-making process. Holding the dose also provides an opportunity for further clarification with the prescribing physician.
C. While reporting a mistake to the pharmacy is important, it may not be the most immediate action to take when dealing with a higher than recommended dose of medication. Direct communication with the prescribing physician is necessary to clarify the order and ensure appropriate action is taken promptly.
