1. The nurse is teaching about the process of exchanging gases through the alveolar capillary membrane. Which term will the nurse use to describe this process?

Analogous or homologous?  Whales evolved from a land mammal that found its way back to the sea and adapted to life underwater.  Thus, whales have lungs and breathe air from the surface like mammals, rather than gills that extract oxygen from the water like fish.  Given this information are the following comparisons examples of analogy or homology?   A) Whale fin and dog front leg (at the level of ‘forelimbs’) B) Whale fin and zebrafish fin (at the level of ‘fin’)

4. The patient is experiencing angina pectoris. Which assessment finding does the nurse expect when conducting a history and physical examination?

16. Which intervention is appropriate to include in the plan of care for a patient experiencing narcolepsy?

A 0.100 M solution of a weak monoprotic acid, HA, has a measured pH of 2.87 at 25 °C. What is the best estimate of Ka for HA?

A student titrates 25.00 mL of 0.100 M acetic acid (Kₐ = 1.8 × 10⁻⁵) with 0.100 M NaOH at 25 °C. What is the best estimate of the pH at the equivalence point? (Use Kw = 1.0 × 10⁻¹⁴.)

A student mixes 50.0 mL of 0.100 M HCl with 30.0 mL of 0.100 M NaOH. What is the pH of the resulting solution? Assume volumes add.

A student mixes 25.00 mL of 0.100 M NH₃ with 20.00 mL of 0.100 M HCl. Which pair of solute species is present in the greatest amounts after the reaction goes to completion?

A 2.50 × 10⁻³ M Ba(OH)₂ solution is prepared at 25 °C. Assuming complete dissociation, what is the pH of the solution?

Which is the correct net ionic equation for the reaction of acetic acid, HC₂H₃O₂(aq), with aqueous hydroxide ion?
