Anurse used a 0.02-mg/l solution of disinfectant to clean a patient’s wound. what is the concentration of the solution expressed as a percentage?

A milligram is 0.001 grams, so if the concentration is 0.02mg/L, it is 0.00002g/L. Therefore, the concentration is 0.00002/1, which can be converted to 2 grams per 100,000 liters, or 0.002%.

20 times a minute is usually the average respritory rate of an adult. additionally the patient is breathing on his own, is clearly maintaining his airway, and is intaking a sufficient amount of air. you shouldn't use a bag valve mask, cpap, or other form of positive pressure ventilation, unless the patient has lost control of his airway, and is not breathing (apneic) or has rapid breathing or slow and shallow respirations. this patient would most likely and should be put on an non-rebreather mask or nrb attached to 100% high flow oxygen at 15 l/min. don't use a nasal cannula, as the amount of oxygen it provides is limited with a rate of 6 l/min.
