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. 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.

When mixing two types of insulin in one syringe, the nurse should follow the mnemonic RN or "regular before NPH". This means that the nurse should first inject air into the NPH vial, then inject air into the regular vial, then withdraw regular insulin from the vial, and finally withdraw NPH insulin from the vial. This order prevents contamination of the regular insulin with NPH insulin and ensures accurate dosing.

Incorrect choices:

a) Inject air into the NPH vial: This is correct, but it is not the next action. The nurse should inject air into the NPH vial before drawing up any insulin.

c) Withdraw NPH insulin from the vial: This is incorrect and can lead to a medication error. The nurse should withdraw NPH insulin after withdrawing regular insulin.

d) Withdraw regular insulin from the vial: This is correct, but it is not the next action. The nurse should inject air into the regular vial before withdrawing regular insulin.
