2026 WGU D116 UNIT 8 EXAM LATEST UPDATED QUESTIONS AND
VERIFIED ANSWERS
1. A patient has an infection caused by Streptococcus pyogenes. The
prescriber is considering prescribing dicloxacillin PO.
What should the provider do?correct answer Question the need for a penicillinase-
resistant penicillin
Provider should consider prescribing another drug
2. A nurse practitioner is teaching a nursing student about a specific
acquired immune system.
Which statement by the student indicates a need for further
teaching?correct answer "The skin is a factor in specific acquired immunity"
Skin is a physical barrier that confers natural immunity
3. An otherwise healthy child receives a varicella virus vaccine.
Three weeks later, the parent calls to report that the child has a mild
case of chickenpox and wonders how this could happen after the
vaccination.
What should the provider tell the parent?correct answer "A varicella-like rash can occur
after the vaccine is given"
Children who receive the varicella vaccine may sometimes develop a mild, local varicella-like rash within a
month of receiving the vaccine
4. A patient has a viral sinus infection, and the provider tells the
patient that antibiotics will not be prescribed. The patient wants to take
an antibiotic and asks the provider what possible harm could occur by
taking an antibiotic. Which response by the provider is correct?correct answer
"Even normal flora can develop resistance and transfer this resistance to pathogens"
Antibiotics make conditions favorable for the overgrowth of microbes with acquired resistance. Normal
flora, which are present at all times, can develop resistance and transfer this resistance to pathogens if
,they occur. Even when pathogens are not present, antibiotic use can promote resistance in the future
5. A patient has a type IV hypersensitivity (delayed-type
hypersensitivity) re-sponse to an infection.
Which two types of cells are necessary for this response?correct answer
Infected macrophages and CD4 helper T cells
,The object of type IV hypersensitivity (delayed-type hypersensitivity) is to rid the body of bacteria that replicate
within macrophages. The macrophage activates the CD4 cell, which in turn activates the macrophage
6. What are penicillins?correct answer Broad spectrum bactericidal antibiotics that inhibit
cell-wall synthesis
Treat positive and negative bacteria
7. What are tetracyclines?correct answer Broad spectrum bacteriostatic abx that inhibit
bacterial protein synthesis
Treat positive and negative bacteria
8. What are fluoroquinolones?correct answer May have bacteriostatic or bactericidal
ettects depending on concen-tration
Inhibit DNA replication and are used to treat urinary, skin, respiratory, and pulmonary
infections Have strong adverse ettects
9. What are lincosamides?correct answer Primarily bacteriostatic abx that act by inhibiting
protein synthesis
Staphylococcus and other serious infections
10. What are macrolides?correct answer Primarily bacteriostatic abx that act on the protein
synthesis of gram-positive bacteria
Often used in situations when hypersensitivity to other abx prevents conventional tx and for respiratory
infections
11. What are sulfonamides?correct answer Bacteriostatic abx that act on the DNA
synthesis of a wide variety of gram-positive and gram-negative bacteria
Skin infections and burns
12. What are glycopeptides?correct answer Bactericidal abx, like vanco, that act on the cell-
wall synthesis of gram-POS-ITIVE only
Used to treat resistant forms of staphylococcus, c. ditt, and other gram-positive infections
13. What are amioglycosides?correct answer Bactericidal abx that act on protein synthesis in
, gram-negative bacteria
E. coli and staphylococcus in situations that contraindicate other medication
