The patient who has had emesis or vomiting for the last 3 days has blood gases of pH of 7.8, HCO3- of 30 mEq/L, and PCO2 of 36 mm Hg. These laboratory values are consistent with which acid-base imbalance?

What is the length of time needed for a drug to reach the minimum effective concentration (MEC)?

A school-age child with a history of asthma has brought a note home from school stating there has been one case of meningitis (Neisseria meningitides) in the school. Since the mother is a nurse, she is very concerned since she knows the portal of entry of this pathogen is:

@X@user.full_name@X@ @GMU: Radioactive substances decay by first-order kinetics. How many years would be required for a sample containing plutonium-94 to decrease to 55.44% of its initial activity? The half-life of plutonium-94 is 2.44e4 years.

@X@user.full_name@X@ @GMU: When 2.795 g of urea was dissolved in 109.8 g of benzene, the boiling point was 354.3 K. What is the formula mass of this compound? The boiling point elevation constant for benzene is 2.53 (°C*kg)/mol. The melting point and boiling points are 5.50°C and 80.10°C, respectively.

@X@user.full_name@X@ @GMU: Initially there were equilibrium concentrations of 0.3344 M A, 0.2118 M B, and 0.1961 M C. Which change will cause the equilibrium to shift from left to right if the reaction is endothermic? Use the reaction below.5A(aq) → 3 B(aq) +3 C(aq) K = 0.424
