29-female with hx of asthma and marijuana vaping arrives in the ED, suspected flu A (pending viral panel). She has temperature of 38.8 C, harsh, painful cough, expiratory wheezing, increased A/P diameter, SOB, RR =28, HR =118. Patient is speaking in short sentences but mentation is OK, A & O x 4. Her SpO2 on RA is 87%. 1 (2) What are your initial priorities for this patient? What interventions and treatments would you order? Bullet points are OK 2 (2) Two hours later her RR = 30, HR = 128, temperature 39.8 C on 50% on Oxymask 8 LPM and SpO2 = 86%. Mentation is OK, A & O x 4, work of breathing remains moderate, still wheezy and scattered diminished but A/P diameter not as hyperinflated. What interventions do you want to make at this time? 3  (1) What supportive interventions would you order for this patient? 4  (1) Two hours later, ABG drawn on 80% FiO2: 7.28 / 44 / 42 / 25.9, WOB is high and high accessory muscle use.

The authorities want to study the true proportion of households using the drop-off location for plastic recycling. They have taken a random sample of 120 households and asked them if they use drop-off facility. Of the sampled households, 45 said they use the drop-off bins.  Find a 95% confidence interval for the true proportion of households using the drop-off location for plastic recycling. Interpret the above calculated interval in the context of the problem. The authorities believe about 35% of the households in the town are using the drop-off location for plastic recycling. Based on the interval in part 1, are the authorities correct? Explain using the interval.
