A nurse is caring for a client who has received an overdose of morphine. The nurse has an order to administer naloxone, an opioid antagonist. Which of the following effects should the nurse expect after giving naloxone?

A high INR indicates that the client is at risk of bleeding due to excessive anticoagulation. The nurse should first assess for signs of bleeding, such as bruising, petechiae, hematuria, or melena.

Then, the nurse should notify the provider and follow orders to reverse the anticoagulation effect, such as administering vitamin K or fresh frozen plasma.

Holding the next dose of warfarin may be appropriate, but it is not the priority action.

Incorrect choices:

a) Administer vitamin K: Vitamin K is an antidote for warfarin overdose, but it should not be given without a provider's order. It may also take several hours to reverse the anticoagulation effect.

b) Notify the provider: Notifying the provider is an important step, but it is not the first action. The nurse should assess the client's condition before calling the provider.

c) Hold the next dose of warfarin: Holding the next dose of warfarin may prevent further anticoagulation, but it does not address the current risk of bleeding. The nurse should assess and intervene for bleeding before holding the medication.

A. Increased respiratory rate: Naloxone is an opioid antagonist that rapidly reverses the effects of opioid overdose, including respiratory depression, sedation, and hypotension. The primary goal of naloxone administration is to restore adequate breathing by increasing the respiratory rate.

B. Decreased pain level:Naloxone reverses opioid effects, which means it can bring back pain that was previously managed by morphine. The client may experience increased pain, not a decrease.

C. Increased sedation:Naloxone reverses sedation, so the client is more likely to become alert and possibly agitated, rather than more sedated.

D. Decreased blood pressure: Morphine can cause hypotension, but naloxone reverses opioid-induced effects, which may result in a rise in blood pressure rather than a decrease.
