Question #: 52 A 35 year old man is in your office and suddenly develops a severe asthmatic wheezing. You decide to use intravenous theophylline for treatment. The pharmacokinetics of theophylline include the following average parameters: Vd-35 L, CL 48 mL/min; half life 8hrs. If an intravenous infusion of theophylline is started at a rate. of 0.48 mg/min, how long will it take to reach >90% of the final steady state concentration?. A. 0.729 hr B. 8 hr C. 16 hr D. 32 hr E. 64 hr

48 You have enoximone 100 mg in 100 mL, and the rate at which the pump is running = 30 mL/hour. What dose is the pump delivering in mcg/kg/min? (Patient's weight = 96 kg)

Question 49 A client with hypernatremia in a hypovolemic state is MOST likely to exhibit what clinical manifestation? Question 49 options: Dry mucus membranes Increased production of dilute urine Increased skin turgor Serum sodium of 140 mmol/L

Could you please answer this question. Thanks so much. What is the ventilator order for this patient? Defend your answer. Patient Barry King is a 27-year-old, asthma patient with COVID-19, who now needs Mechanical ventilation due to respiratory failure related to complications from COVID. He currently weighs 75kg. His current vitals are as follows: RR-24, Breath sounds- coarse crackles in both lungs. His temperature is 102.3, BP- 152/100, HR- 115 bpm, FiO2 on 50% high flow oxygen and ABG results are:pH- 7.29, PACO2-58, PAO2-49, HCO3-23. The MD wants you to suggest ventilator orders for RT to carry out. Please write reasonable orders and defend your order (include Vt, RR, Mode, PEEP, FiO2 and other procedures or orders that would help).
