A nurse is preparing to administer naloxone IV bolus to a client who has opioid use disorder and has developed acute opioid toxicity. Which of the following actions should the nurse take?
Check the client's vital signs every 15 min.
Give the naloxone slowly for 15 seconds.
Expect the onset of naloxone to occur in 15 min.
Anticipate the effects of naloxone to last for 24 hr.
The Correct Answer is A
A. Vital signs should be monitored every 15 minutes because naloxone has a short duration and the client may experience opioid re-sedation as the antagonist wears off.
B. Naloxone should be administered over 2 minutes, not 15 seconds, to reduce abrupt opioid withdrawal symptoms.
C. Naloxone has a rapid onset (1-2 minutes IV, 2-5 minutes IM).
D. The effects of naloxone last only 30-90 minutes, requiring repeated doses if opioids are still in the system.

Correct Answer is B
Explanation
A. Insulin vials should not be shaken because this can create air bubbles, leading to inaccurate dosing. Instead, NPH insulin should be gently rolled between the palms to evenly mix the suspension. Regular insulin does not require mixing.
B. Once regular and NPH insulin are mixed, they should be administered promptly to maintain their stability and effectiveness. Delaying administration may alter insulin absorption, leading to unpredictable glucose control.
C. Regular insulin should be drawn up before NPH insulin to prevent contaminating the clear regular insulin with the cloudy NPH insulin. The correct order is to inject air into the NPH vial first (without withdrawing insulin), then inject air into the regular insulin vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
D. The correct technique is to first inject air into the NPH vial, then inject air into the regular insulin vial. This prevents contamination and maintains sterility. However, when withdrawing insulin, regular insulin is drawn first to prevent mixing of NPH insulin into the regular insulin vial.
Correct Answer is D
Explanation
A. Empty the collection chamber every 8 hr – Incorrect. The collection chamber is not emptied; instead, it is replaced when full to prevent air re-entry.
B. Check the patency of the tubing every 2 hr – While monitoring the tubing is essential, checking patency is not the most specific nursing priority.
C. Keep the drainage system above the level of the client's chest – Incorrect. The system should remain below chest level to prevent backflow of drainage.
D. Ensure 2 cm (0.8 in) of water is in the water seal chamber – Correct. The water seal chamber maintains negative pressure and prevents air from entering the pleural space, making this a crucial step in chest tube management.
