A nurse calls a health care provider to report that a client with congestive heart failure (CHF) is exhibiting dyspnea and worsening of wheezing. The health care provider, who is in a hurry because of a situation in the emergency department, gives the nurse a telephone prescription for furosemide (Lasix) but does not specify the route of administration. What is the appropriate action on the part of the nurse?

Telephone prescriptions involve a health care provider dictating a prescribed therapy over the telephone to the nurse. The nurse must clarify the prescription by repeating it clearly and precisely to the health care provider. The nurse then writes the prescription on the health care provider's prescription sheet or enters it into the electronic medical record. It is crucial not to interpret an unclear prescription or administer a medication by a route that has not been expressly prescribed. In this case, the nurse should call the health care provider who gave the telephone prescription to clarify the prescription, ensuring the correct route of administration is specified. Options B, C, and D are incorrect because administering the medication without clarification, seeking assistance from the nursing supervisor, or choosing an arbitrary route of administration can compromise patient safety and violate medication administration protocols.
