The following order has been written for your client: morphine 1 mg intravenously (IV) every 2 hours as needed for pain. Which of these is true regarding this order?
If the client is still in severe pain 1 hour after the last dose, the nurse can administer an additional 1 mg of morphine.
Morphine will be given enterally.
Every two hours, the nurse will assess the need for morphine to determine if 1 mg IV should be given.
Morphine will be given every 2 hours.
The Correct Answer is C
The order states that morphine 1 mg should be given intravenously (IV) every 2 hours as needed for pain. This means that the nurse should assess the client's pain level every 2 hours and determine if 1 mg of morphine IV is needed to manage the pain.
Option A is incorrect because the order specifies that morphine should be given every 2 hours as needed, not every hour.
Option B is incorrect because the order specifies that morphine should be given intravenously (IV), not enterally.
Option D is incorrect because the order specifies that morphine should be given as needed for pain, not automatically every 2 hours.

Explanation
In pharmacodynamics, receptors play a crucial role in mediating the effects of medications ¹. Medications must bind with receptors to mimic or block the actions of the body's own regulatory molecules ¹. This binding can activate or inhibit the receptor, leading to a biological response ¹.
Option B is incorrect because activation of the receptor by the medication does not necessarily cause the cell to develop a new function.
Option C is incorrect because receptors do not start the process of metabolism of the medication by the liver.
Option D is incorrect because binding a medication to a receptor does not necessarily make the medication more selective to that type of receptor.
