Exam 3: Bacteria and Archaea

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. As an RN in a primary care office, you recently took care of a 15-year-old patient with severe gastrointestinal distress. Since the patient had experienced diarrhea, vomiting, and a fever for 4 days, a stool culture was ordered in an attempt to identify a disease-causing pathogen. The laboratory results have just been faxed over to your office and you begin to read the data. -Microscopic analysis revealed the presence of gram-negative bacilli in the patient's stool.Based upon this information,you picture in your mind which of the following images?

The difference in cell wall structure of Mycobacterium and Nocardia compared to the typical gram-positive bacterial cell wall structure is

The outcome of the Gram stain is based on differences in the cell's

If bacteria living in salty seawater were displaced to a freshwater environment,the cell structure that would prevent the cells from rupturing is the

Chemical analysis of a bacterial cell structure detects calcium and dipicolinic acid.What is the identity of this structure?

Flagella move in a whiplike motion.

The site(s)for most ATP synthesis in bacterial cells is(are)the

Which of the following is mismatched?

Endospores of certain bacterial species can enter tissues in the human body,germinate,and cause an infectious disease.

Lipopolysaccharide is an important cell wall component of

Each bacterial species represents a distinct organism that can produce viable offspring when mating with other bacteria of its kind.

Gram-negative bacteria

The two functions of bacterial appendages are

Which of the following is not a phenotypic trait of bacteria?

Bacterial endospores are not produced by

The slime layer provides bacteria greater pathogenicity as compared to the capsule.

The term that refers to the presence of a tuft of flagella emerging from the same site is

A flagellum is anchored into the bacterial cell envelope by its

If during the Gram stain procedure,the bacterial cells were viewed immediately after crystal violet was applied,gram-positive cells would be purple but gram-negative cells would be colorless.

Please read the clinical scenario, and then answer the question that follow to become familiar with the traditional NCLEX question format. As a triage nurse in the ER, you begin the assessment of an elderly patient complaining of bloody diarrhea and severe stomach cramps. You find the patient has a fever of 104oF as well, and is showing signs of dehydration. IV fluids are administered while further analysis of the patient continues. -Testing is performed on the specimen in the laboratory.The Gram stain is an important test,as it differentiates bacteria into two broad classes: gram positive and gram negative.Which step in this process is the differential step,for it only acts upon one type of cell?
