A nurse is assessing a client who has oxygen toxicity. Which of the following findings should the nurse expect?
Metallic taste in mouth
Facial flushing
Muscle twitching
Periorbital edema
The Correct Answer is C
A. Metallic taste in the mouth:
This is not a typical finding of oxygen toxicity. Metallic taste may be associated with other factors but is not a specific indicator of oxygen toxicity.
B. Facial flushing:
Facial flushing is not a typical finding in oxygen toxicity. It is more commonly associated with other conditions, such as certain allergic reactions or vasodilation.
C. Muscle twitching
Muscle twitching, also known as myoclonus, is a recognized symptom of central nervous system oxygen toxicity. High concentrations of oxygen, particularly at increased pressures, can cause neurotoxic effects leading to muscle twitching, dizziness, and even convulsions.
D. Periorbital edema:
Periorbital edema is not a common manifestation of oxygen toxicity. It is more commonly associated with conditions related to fluid balance or kidney function.

Explanation
Clindamycin is an antibiotic that can treat infections caused by staphylococci bacteria. It can be given by intermittent IV bolus, which means injecting the drug into a vein over a short period of time. To calculate the infusion rate for clindamycin, we need to use the formula:
Infusion rate (ml/hr) = Volume (ml) / Time (hr)
In this case, the volume is 50 ml and the time is 0.5 hr (30 min). Plugging these values into the formula, we get:
Infusion rate (ml/hr) = 50 ml / 0.5 hr
Infusion rate (ml/hr) = 100 ml/hr
Therefore, the nurse should set the IV pump to deliver 100 ml/hr of clindamycin.
Correct Answer is C
Explanation
A. Close the fire doors on the unit:
Closing fire doors is a safety measure to contain smoke and flames, but activating the fire alarm is the priority to ensure a swift and comprehensive response.
B. Use a fire extinguisher to put out the fire:
While using a fire extinguisher is an important action, it should come after activating the fire alarm. The fire alarm alerts everyone to the emergency, and then the appropriate personnel can use fire extinguishers as needed.
C. Move any clients in the immediate vicinity:
Priority action during a fire: The priority in any fire situation is to ensure the safety of individuals in the immediate area. The acronym RACE is commonly used in healthcare settings to outline the steps to take in the event of a fire:
- Rescue anyone in immediate danger.
- Alarm: Activate the fire alarm.
- Contain the fire by closing doors.
- Extinguish the fire if it is small and safe to do so, or Evacuate the area if necessary.
