EXTRA CREDIT: +4 points possible   A titration is performed using sodium hydroxide, NaOH, at a concentration of 0.1211 M to determine the concentration of a hydrochloric acid solution of unknown concentration. A volume of 10.00 mL of the hydrochloric acid solution is used in each trial. Using the balance chemical reaction and data table below, determine the concentration of the hydrochloric acid solution. HCl(aq) + NaOH(aq) –> NaCl(aq) + H2O(l) Concentration of NaOH 0.1211 M Volume of HCl used 10.00 mL Initial buret reading of NaOH 0.35 mL Final buret reading of NaOH 14.20 mL

The clinic nurse is reviewing patient charts for the next day. Which patient would the nurse identify as most at risk for developing coronary artery disease? 

The nurse is assessing a 45-year-old female sex who has an elevated fasting blood glucose and is on furosemide (Lasix) for hypertension. What other assessment finding would indicate this patient has metabolic syndrome? 

A 46-year-old patient presents to the clinic with complaints of fever, chills, and malaise, which has progressively gotten worse over the past three days.
