Final Answer:
Yes, it is within the licensed practical nurse's scope of practice to administer an initial dose of 4mg of morphine and provide an additional 4mg if the patient's pain persists, as long as the maximum range of 8mg is not exceeded within any 4-hour time frame.
Step-by-step explanation:
In the given order for morphine (4-8mg IV every 4 hours, prn), the range indicates the flexibility in dosage based on the patient's needs. Administering an initial dose of 4mg is appropriate, and if the pain persists, an additional 4mg may be given within the specified time frame. However, it is crucial not to exceed the maximum limit of 8mg within any 4-hour period.
To further elaborate, the initial dose of 4mg serves as a starting point, and the additional 4mg can be administered if needed, ensuring a cumulative total does not surpass 8mg within a 4-hour window. This approach aligns with the healthcare provider's order and allows for personalized care based on the patient's response to the initial dosage.
Adhering to the specified dosage range is essential for patient safety and effective pain management. The nurse should closely monitor the patient's response to each dose, document the administration accurately, and communicate any concerns or notable changes in the patient's condition to the healthcare team. This approach ensures that the LPN operates within their scope of practice while providing patient-centered care in accordance with the prescribed medication order.
