Final answer:
Coach Kelly should shake the inhaler and remove the mouthpiece cover, possibly attaching a spacing device, to safely prepare it for Emily's use. Testing the inhaler on others or calling for permission are unnecessary steps.
Step-by-step explanation:
Before Coach Kelly hands the inhaler to Emily, she should perform two critical steps to ensure the medication is delivered correctly and safely. First, she should shake the inhaler to mix the medication properly, which is often a necessary step to prepare the medication for use. Secondly, she should remove the mouthpiece cover and, if available, attach a spacing device. The spacing device helps to ensure that the medication is inhaled correctly into the lungs. It is important to note that Coach Kelly should not test the inhaler on herself or a bystander, and she should not need to call Emily's parent for permission, as the use should have been pre-arranged as part of Emily's asthma management plan.
