Ninа wоrks in reseаrch аnd develоpment department оf a large pharmaceutical lab. Nina's team is working on finalizing a laboratory clinical trail that has been in progress for the last 7 days. Nina is coming near the end of a 12-hour long shift, and is feeling a bit fatigued. While working on the final stage of the trial, she mixes the wrong chemical compounds together, which unfortunately invalidates the entire experiment. Now her team will be forced to start the entire clinical trial over again, which means it will take at minimum an additional 7 days until the experiment can be completed.   This would be an example of which one of the following types of risk?

Her v/s are BP: 110/70, P: 110, RR: 24/min, SpO₂: 92% on room air. On physical exam, the nurse practitioner observes accessory muscle use and auscultates diffuse expiratory wheezing. Using GINA guidelines, what is the best initial management?
