NAGELHOUT CHAPTER 15: CHEMISTRY
AND PHYSICS FOR NURSE ANESTHESIA
ACTUAL EXAMQUESTIONS WITH ANSWERS
GRADED A+
Question 1
How does the radius of a tube affect flow according to Poiseuille's law?
Correct Answer
Doubling the radius results in a 16-fold increase in flow.
Question 2
What is the role of intermolecular forces in gases?
Correct Answer
They are weaker than kinetic energy, allowing gas molecules to move freely.
Question 3
What does 'a' measure in the Van der Waals equation?
Correct Answer
The attraction between the particles.
Question 4
What is the significance of molecular modeling?
Correct Answer
It expands the understanding of molecular geometries and behaviors.

,Question 5
What is wavelength?
Correct Answer
The distance from one wave crest to the next.
Question 6
What is a double covalent bond?
Correct Answer
The sharing of two pairs of electrons between atoms.
Question 7
How does mass differ from weight?
Correct Answer
Mass is the total amount of matter in an object, while weight is the total effect of
gravity on that mass.
Question 8
How much volume does one mole of gas occupy at standard temperature and
pressure?
Correct Answer
22.4 liters.
Question 9
What is the equivalent of 1 atm in mm Hg?
Correct Answer
1 atm is equivalent to 760 mm Hg.

,Question 10
What are alkenes?
Correct Answer
Alkenes are hydrocarbons that contain one or more double bonds between carbon
atoms.
Question 11
What does 'b' represent in the Van der Waals equation?
Correct Answer
The volume excluded by a mole of particles.
Question 12
What is the normal range for systemic vascular resistance (SVR)?
Correct Answer
Normal SVR is 800 to 1200 dyne sec/cm5.
Question 13
What does the term 'dyne' refer to?
Correct Answer
The dyne is a smaller unit used to express measures of force.
Question 14
What is the wall tension of a normal aorta with a radius of 2 cm and mean pressure of
100 mm Hg?
Correct Answer
2.66 N/cm

, Question 15
What is the formula for gravitational acceleration?
Correct Answer
g = G * (Me / r²e), where g is gravitational acceleration, G is the gravitational
constant, Me is the mass of Earth, and r²e is the mean radius of Earth.
Question 16
What do valence shell electron pair repulsion (VSEPR) diagrams represent?
Correct Answer
They depict electron repulsion and the geometric distribution of atoms in covalently
bonded molecules.
Question 17
What is the formula that describes the relationship in Henry's Law?
Correct Answer
p = kc, where p is the partial pressure, k is Henry's constant, and c is the
concentration of the solute.
Question 18
What is the significance of the conservation of energy in fluid dynamics?
Correct Answer
More energy is imparted toward velocity as opposed to pushing on the walls of the
tube.
Question 19
What is the role of temperature in the solubility of gases?
Correct Answer
Lower temperatures allow more gas to dissolve in liquids due to decreased kinetic
energy.
