 If lucky people earn Ylucky=100 and unlucky people earn Yunlucky=50 with a 50/50 chance symmetrical luck component μ, s.t.μlucky= -μunlucky what is the value of μ?

A nurse is caring for a patient who is being treated for Covid-19 pneumonia and ARDS and requires a mechanical ventilator. The physician orders an arterial blood gas, which provides the following results: pH = 7.18, pCO2= 48 mmHg, HCO3= 29 mEq/L, SaO2=92%. Based on these results, which of the following best describes this patient’s condition?

A client converts from normal sinus rhythm at 80 bpm to atrial fibrillation with a ventricular response at 166 bpm. Blood pressure is 162/74 mm Hg. Respiratory rate is 20 breaths per minute with normal chest expansion and clear lungs bilaterally. IV heparin and Diltiazem are given. The nurse caring for the client understands that the main goal of treatment is what?

Please name 4 manifestions of a tension pneumothorax (2 must be specific, and 2 can be considered for any type of pneumothorax). Good luck!! Total 1 point E.C. available – 0.25 point for each answer.
