Case Study 2 Quiz  Question 1 2 / 2 pts Match the following terms: When an antibiotic is ... prescribed based on susceptibility testing When an antibiotic is prescribed to prevent an infection from occurring When an antibiotic is prescribed based on symptoms/signs of an infection  Question 2 2 / 2 pts Which of the following is NOT a common sign/symptom of a urinary tract infection? Rash and hives on the skin.

Lower abdominal pain.  Question 3 2 / 2 pts What is the most common causative agent of uncomplicated urinary tract infections? Uropathogenic Staphylococcus aureus (UPSA). Uropathogenic Pseudomonas aeruginosa (UPPA). Uropathogenic Escherichia coli (UPEC). Uropathogenic Enterococcus faecalis (UPEF).  Question 4 2 / 2 pts What does the term "superbug" refer to in the context of antimicrobial resistance? Any microbe that is exposed to an antibiotic. A microbe that has acquired resistance to multiple antimicrobial agents. A microbe that is susceptible to antibiotics. A microbe that has developed a new form of infection. A microbe that mutates under the selective pressure of the immune system.  Question 5 0 / 2 pts True or False: Transformation is a process that can only occur in a limited number of bacterial species. True False  Question 6 2 / 2 pts In a laboratory setting, how might you demonstrate transduction as a method of horizontal gene transfer? Mix a bacterial culture with a viral phage known to carry resistance genes. Culture bacteria on a medium containing dead cells with resistance genes. Use a chemical agent to induce pili formation between bacterial cells. Apply an electrical current to increase the uptake of environmental DNA by bacteria. Heat shock bacteria to induce spontaneous uptake of resistance genes.  Question 7 2 / 2 pts Which strategy do bacteria use to reduce the intracellular concentration of an antibiotic? Synthesizing more nucleic acids. Change pores of channels, reducing the cell’s permeability to the drug. Increasing metabolic pathways. Binding the antibiotic to extracellular proteins. Releasing the antibiotic into the environment by simple diffusion  Question 8 2 / 2 pts The E-test differs from the disk diffusion test because it: Uses a gradient of antibiotic concentrations to find the MIC. Determines the genetic basis of bacterial resistance. Requires bacterial culturing in a broth medium. Indicates whether an antibiotic is bactericidal or bacteriostatic. Is used exclusively for viral infections.  Question 9 2 / 2 pts True or False: Handwashing according to protocols is a responsibility of healthcare workers under antibiotic stewardship to prevent the spread of resistant infections. True False  Question 10 0 / 2 pts Which of the following is NOT listed as a reason that healthcare settings are perfect for the spread of resistant microbes? Many transmission opportunities. Limited pathogen presence. Presence of many drugs. Many pathogens. Unregulated antibiotic use in developing countries. Quiz Score: [Show More]
