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
organellesdescribes a prokaryotic cell.
2. A nurse is instructing the staff about cellular functions. Which cellular function is the
nursedescribing when an isolated cell absorbs oxygen and uses it to transform nutrients to
energy?
a. Metabolic absorption
b. Communication
c. Secretion
d. Respiration

NURS 6325Patho Test Bank.
by Huether, McCance Test Bank
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
cellsfunction 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
ribonucleicacid, most of the DNA, and DNA-binding proteins, is the nucleolus.
