NURS PATHO EXAM TEST BANK 7T ED LATEST VERSION
UPDATED AND REVISED IN 2025 A+
Chapter 1. Cellular Biology
MULTIPLE CHOICE
1. A student is observing a cell under the microscope. It is observed to have
supercoiled DNA with histones. Which of the following would also be observed
by the student?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled
DNA within its nucleus; thus, the nucleus should be observed.
A single circular chromosome is characteristic of prokaryotic cells, which do not have
histones.
Free-floating nuclear material describes a prokaryotic cell, which would not have
a distinct nucleus.
Eukaryotic cells have membrane bounded cellular components called organelles.
No organelles describes a prokaryotic cell.
2. A nurse is instructing the staff about cellular functions. Which cellular
function is the nurse describing when an isolated cell absorbs oxygen and uses it
to transform nutrients to energy?
,a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration
,ANS: D
The ability of the cell to absorb oxygen refers to the cells function of respiration.
The ability of the cell to function within a society of cells refers to its
function of communication.
The ability of the cell to take in nutrients refers to the cells function of metabolic
absorption.
The ability of the cell to synthesize new substances and secrete these elsewhere
refers to the cells function of secretion.
3. A eukaryotic cell is undergoing DNA replication. In which region of the cell
would most of the genetic information be contained?
a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus
ANS: C
The region of the cell that contains genetic material, including a large amount
of ribonucleic acid, most of the DNA, and DNA-binding proteins, is the
nucleolus.
The mitochondria is the site of cellular respiration.
The ribosomes are involved in manufacturing of proteins within the cell.
The nucleus contains the nucleolus, and it is the nucleolus that contains genetic
material.
4. The fluid mosaic model for biologic membranes describes membrane behavior.
, According to this model, which of the following float singly or as aggregates in
the fluid lipid bilayer?
a. Peripheral membrane proteins
b. Integral membrane proteins
