Explain water's concave meniscus in terms of cohesive and adhesive forces - ansCohesive forces are the
attractions between particles of the same type, such as the bonds between water molecules whereas
adhesive forces are attractions between a particle of one type and particles of a different type, such as
the bonds between water molecule and those of its glass container. These cohesive and adhesive forces
combine to cause liquids to form a meniscus (curved surface) in a glass tube. A liquid with strong
cohesive forces, such as water, tries to roll itself into a ball to minimize surface tension, but water is also
attracted to the walls of any tube by adhesive forces, causing the water to form a concave meniscus.
Explain why sugar can be made to dissolve more quickly by grinding it to a fine crystal - ansGrinding
sugar to a fine crystal increases the surface area of the crystal and this makes it dissolve more quickly
because solute particles dissolve by leaving the surface of their bulk structure which is in contact with
the solvent
Explain why the vapor pressure of a liquid increases with increasing temperature - ansWater molecules
in the liquid state freely vibrate and rotate. As the temperature rises, the vibrations and rotations
become intense enough to overcome the forces that keep the molecules together. The molecules begin
to undergo translational motion allowing the molecules to convert to the vapor state and these exert a
pressure above the still-existing liquid molecules called the vapor pressure of the substance. Higher
temperature = greater conversion to vapor = higher vapor pressure
Fluids - anssubstances like liquids and gases which have no fixed shape and so they flow
Ionization - ansthe splitting of molecules to form ions
List and describe the two components of a solution - ansThe minor component of a solution which is
being dissolved is called the solute while the major component doing the dissolving is called the solvent.
Molality - ansthe number of moles of solute present per kilogram of solvent
Molarity - ansthe number of moles of solute present per liter of solution

Nonelectrolytes - anscompounds which dissolve to form solutions of molecules which do not conduct an
electric current
Phase - ansany state of matter such as solid, liquid or gas
Strong electrolytes - anssolutes that ionize completely
Sublimation - ansthe conversion of a solid directly to the gas state
Surface tension - ansthe force that causes a liquid which is in contact with a gas like air to assume a
shape that has the least amount of surface area causing the surface to act like a thin elastic sheet
Triple point - ansthe temperature and pressure at which the solid, liquid and gas phases can coexist
Vapor pressure - anspressure exerted by vapor molecules above a liquid
Weak electrolytes - anssolutes that only partially ionize
What rule is used to predict the solubility of materials? - ansThe "like dissolves like" rule is used to
predict the solubility of materials with polar solvents only dissolving polar (and ionic) substances and
nonpolar solvents only dissolving nonpolar substances.
Why are liquids the least common state of matter? - ansthey can exist only within a relatively narrow
range of temperatures and pressures
Why does a bottle of soda pop "fizz" when it is opened? - ansWhen a bottle of soda pop is opened, the
pressure above the solution decreases and some of the carbon dioxide bubbles off since a lower
pressure allows the gas molecules in the solution to escape

Why does a phase change occur at one temperature rather than over a temperature range? - ansDuring
a phase change, the temperature of the material remains constant as all of the energy being added is
being used to overcome forces of attraction between the particles and separate them so the
temperature does not rise. Over any other portions of the temperature range, when a material is
heated, the temperature of the material will rise as the energy added causes the molecules to move
faster and demonstrate a higher temperature, which is really a measure of the kinetic energy of the
molecules
Why does a temperature increase usually increase the solubility of a solid? - ansDissolving most solids is
an endothermic process; doing so absorbs heat. Adding heat (by increasing the temperature of a
solution) causes any dissolving process to change in the direction that consumes the added energy. For a
solid or liquid, heat is absorbed as the solute dissolves in water (heat of solution is endothermic,
requiring energy) so a solid or liquid is more soluble at a higher temperature
Why does diffusion take place quickly in a gas, more slowly in a liquid and not at all in a solid? -
ansDiffusion is the non-energy-requiring movement of particles from regions of higher concentration to
regions of lower concentration. Diffusion in a liquid occurs more slowly than in a gas since the gas
particles are moving more rapidly. Solids do not show the property of diffusion since the particles in a
solid can only vibrate around a fixed point rather than move throughout the sample.
Why is liquid water more dense than ice? - ansIce has empty spaces between the
molecules in its structure as compared to liquid water
. "Red Man" Syndrome may occur during the administration of vancomycin (Vancocin), primarily due to -
ansAn increase in histamine production
*WRONG* Which medication is used to treat iron toxicity? - ansA) digoxin immune fab (Digibind)
B) Naloxone (Narcan)
C) Mephyton (Vitamin K)
D) *WRONG* deferoxamine (Digibind)

a patient who has undergone a hip replacement? - ansA)*WRONG* heparin B) enoxaparin

A nurse is caring for a patient with hyperparathyroidism and notes that the patient's serum calcium level
is 13mg/dl. Which medication should the nurse prepare to administer as prescribed to the patient? -
anscalcintonin (Miacalcin)
A patient has a prescription to take Guaifenesin (Mucinex) every 4 hours, as needed. The nurse
determines that the patient understands the MOST effective use of the medication if the patient states
that he or she will: - anstake the medication with a full glass of water
A patient's capillary blood glucose reading is 33mg/dl. Which of the following medications will the nurse
administer if the patient is unable to tolerate PO? - ansDextrose 50% IV push
A provider orders one liter of NS to be infused over four hours. At what rate would you set the IV pump?
- ans250ml/hr
Acetylsalicylic acid (Aspirin) has which of the following pharmacological effects? - ansAnti-inflammatory,
anti-pyretic, decrease platelet aggregation
Convert 1.2 milligrams to micrograms - ans1200 mcg
Normal Saline (NS) is the solution of choice over D5W when preparing to administer a blood transfusion
because: - ansNormal Saline is an isotonic solution and prevents cell hemolysis
