Nokea
A 78-year-old patient is in the recovery room after having a lengthy surgery on his hip. As he is gradually awakening, he requests pain medication. Within 10 minutes after receiving a dose of morphine sulfate, he is very lethargic and his respirations are shallow, with a rate of 7 breaths/minute. The nurse prepares for which priority action at this time?
- A. Assessment of the patient's pain level
- B. Immediate intubation and artificial ventilation
- C. Administration of naloxone (Narcan)
- D. Close observation of signs of opioid tolerance
Correct Answer: C
Rationale: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose, such as respiratory depression. The patient's symptoms of lethargy and shallow respirations at 7 breaths/minute indicate a potential opioid overdose, making naloxone administration the priority action. The other options are not appropriate in this urgent situation.

A patient is to receive methadone 2.5 mg intramuscularly (IM) now. The medication is available in a concentration of 10 mg/mL. Identify how many milliliters of methadone will be drawn up for this dose.
Correct Answer: 0.25 mL
Rationale: 10 mg : 1 mL :: 2.5 mg : x mL; (10 * x) = (1 * 2.5); 10x = 2.5; x = 0.25 mL.

A patient with a history of chronic pain has been using an opioid analgesic for 4 months and reports that a larger dose of the pain medication is needed for the same pain relief. The nurse is aware that this patient is experiencing which of these?
- A. Opioid addiction
- B. Opioid tolerance
- C. Opioid toxicity
- D. Opioid abstinence syndrome
Correct Answer: B
Rationale: Opioid tolerance is a common physiologic result of long-term opioid use. Patients with opioid tolerance require larger doses of the opioid agent to maintain the same level of analgesia. This situation does not describe toxicity (overdose), addiction, or abstinence syndrome (withdrawal).
The nurse is assessing a patient who has been admitted to the emergency department for a possible opioid overdose. Which assessment finding is characteristic of an opioid drug overdose?
- A. Dilated pupils
- B. Restlessness
- C. Respiration rate of 6 breaths/min
- D. Heart rate of 55 beats/min
Correct Answer: C
Rationale: The most serious adverse effect of opioid use is CNS depression, which may lead to respiratory depression. Pinpoint pupils, not dilated pupils, are seen. Restlessness and a heart rate of 55 beats/min are not indications of an opioid overdose.
