lisabon 2012 [21]
I think the nurse should asses the blood pressure, skin color, and moisture. Sinus bradycardia may be defined as a sinus rhythm with resting heart rate of 60 beats per minute or less. However few patients become symptomatic until their heart rate drops to less than 50 beats per minute. Intervention for sinuses bradycardia should be based on assessment of the clients condition. The patient may remain asymptomatic, the nurse may choose to increase the IV flow rate, administer atropine, or notify the Rapid Response Team depending on the severity of the symptoms.

Ronch [10]
The statement above is FALSE. In the scenario given above the doctor is working at the organ level. This is because, he is working with lung which is an organ that participates in breathing. The lung is an organ because it is made up of different tissues which are in turn made up of different cells. 
Working at the cellular level involve working with cells. For instance, when a microbiologist is growing a cell in a culture, he is working at a cellular level.
