A nurse is consulting a formulary about a client's new prescription for raloxifene. The nurse should identify that this medication is used to treat which of the following conditions?

A. Pruritus, which is itching, is a common adverse effect associated with the use of opioids, including morphine. Itching can occur when opioids are administered through various routes, including epidural infusion. The exact mechanism for opioid-induced itching is not fully understood, but it is thought to be related to the release of histamines or other chemical mediators.
B. Gastric bleeding is not a common adverse effect of epidurally administered opioids like morphine. Gastric bleeding is more associated with non-steroidal anti-inflammatory drugs (NSAIDs) and certain other medications.
C & D. Tachypnea (rapid breathing) and cough are not typical adverse effects of epidurally administered opioids. However, opioids can cause respiratory depression (slow and shallow breathing), so monitoring respiratory status is important when using these medications.

A. Naloxone IV:
This choice is incorrect. Naloxone is an opioid receptor antagonist used to reverse the effects of opioid overdose. It works by displacing opioids from the receptors and rapidly reversing their effects. However, in this scenario, the client is experiencing pain 1 hour after receiving morphine, indicating that the morphine's analgesic effects have likely worn off. Naloxone is not used to manage pain, but rather to reverse opioid overdose.

B. Fentanyl transmucosal:
This choice is incorrect. Fentanyl transmucosal formulations are used for breakthrough pain in opioid-tolerant patients with chronic pain conditions. It is not typically the first choice for immediate pain relief after intravenous morphine administration. Additionally, it's worth noting that fentanyl transmucosal products, like fentanyl lollipops, are usually reserved for chronic pain management and may not be suitable for immediate post-administration pain relief.

C. Morphine tablet:
This is the correct choice. If the client is experiencing pain 1 hour after receiving morphine intravenously, it's reasonable to administer an oral or sublingual form of morphine for continued pain relief. Morphine tablets are commonly used for pain management and can provide sustained relief over a longer duration. This choice aligns with the patient's initial prescription for pain control.

D. Lidocaine patch:
This choice is incorrect. Lidocaine patches are used to manage localized neuropathic pain, such as postherpetic neuralgia. They work by numbing the skin and underlying tissues in the area where they are applied. While lidocaine patches can be effective for certain types of pain, they are not typically used to address the acute pain associated with cancer and immediate post-administration pain relief.
