A nurse is reviewing a client's laboratory results before administering furosemide 40 mg IV bolus. For which of the following values should the nurse withhold the medication and contact the provider?

Choice A Reason:
Contact the provider to clarify the prescription is not appropriate. Contacting the provider might not be necessary in this case. The prescription specifies "NOW," indicating an urgent administration, which is a clear directive to administer the medication promptly without further clarification.
Choice B Reason:
Administer the medication within 90 minutes is appropriate. "NOW" typically implies an urgent need for administration, and within a hospital setting, "NOW" often indicates a timeframe of around 90 minutes for prompt administration of the medication.
Choice C Reason:
Notify the pharmacy to send the medication immediately is inappropriate. With the prescription stating "NOW," the need for immediate administration usually requires using the hospital's available stock of the medication rather than waiting for delivery from the pharmacy. This action might cause a delay in administration.
Choice D Reason:
Inform the client there is a prescription available if needed is inappropriate. This option is not suitable in this scenario. "NOW" in the prescription implies the immediate need for administration, so informing the client about the availability of the prescription doesn't align with the urgency implied by the directive "NOW."

Choice A Reason:
Levothyroxine 100 mcg PO every morning is incorrect. Indicates the dosage (100 mcg) and the route (by mouth) to be taken every morning.
Choice B Reason:
Simvastatin 40 mg PO at bedtime: Specifies the dosage (40 mg) and the timing (at bedtime) for administration.
Choice C Reason:
Acetaminophen 500 mg every 4 hr RN for fever is correct. The term "RN" in this context might be interpreted as "right now" rather than the intended meaning, which could cause confusion regarding the frequency of acetaminophen administration. The nurse should seek clarification to ensure accurate and safe dosing instructions.
Choice D Reason:
Morphine 4 mg IV every 4 hr PRN for pain: Specifies the dosage (4 mg), the route (intravenous), and the frequency (every 4 hours as needed) for pain management.
