Nokea
A client comes to the clinic reporting fever, chills, and coughing. The client is found to be positive for influenza. The nurse is aware that influenza is transmitted from one infected person to another. What type of infectious disorder is this considered?
- A. Localized
- B. Generalized
- C. Communicable disease
- D. Health-care-associated
Correct Answer: C
Rationale: Communicable diseases are infectious disorders that are transmitted from one infected species to another. Common signs and symptoms are the same as generalized plus organ-specific or disease-specific manifestations. Examples of the infections transmitted are influenza, chickenpox, and tuberculosis. Localized infection is confined to a small area such as a furuncle (boil). Generalized infection is a systemic or widespread infection in one or two organs such as urosepsis. A health-care-associated infection is acquired in a health care agency.

A client is diagnosed with a viral illness and requests an antibiotic to 'cure' the illness. When the request is refused by the physician, the client states to the nurse, 'I will never get better.' What is the best response by the nurse?
- A. I will speak with the physician again. You will only get better while taking an antibiotic.'
- B. Prescribing antibiotics for a viral infection may result in drug-resistant bacteria.'
- C. You need to think positively, and you will get better soon.'
- D. Taking antibiotics when you don't need them will make you sick.'
Correct Answer: B
Rationale: Causes of antibiotic resistance, a consequence of bacterial mutations that interfere with the mechanism of antibiotic action, are related to inappropriate prescription of antibiotics for viral (rather than bacterial) infection. Because viral infections are often self-limiting, with symptoms control, the client will get better. Indicating that the client is not thinking positively is a nontherapeutic comment. Informing the client that taking unnecessary antibiotics will cause illness is not detailed enough to be an informative response.
The nurse has been injured with a needlestick while caring for a newly admitted client and informs the charge nurse. What is the next thing the injured nurse should do?
- A. Document the injury in writing.
- B. Obtain the client's HIV status.
- C. Get instructions on monitoring potential symptoms.
- D. Report the injury to the supervisor.
Correct Answer: A
Rationale: Should an injury occur, health care workers are advised to follow postexposure recommendations: (1) Report the injury to one's supervisor immediately; (2) document the injury in writing; (3) identify the person or source of blood, if possible; and (4) obtain the HIV and hepatitis B statuses of the source of blood, if it is legal to do so. Unless the client gives permission, testing and revealing HIV status are prohibited; (5) obtain counseling on the potential for infection; (6) receive the most appropriate postexposure prophylaxis; (7) be tested for disease antibodies at appropriate intervals; and (8) receive instructions on monitoring potential symptoms and medical follow-up.
A client arrives at the clinic reporting vaginal discharge after having sexual intercourse 1 week ago. The client is diagnosed with gonorrhea and given a prescription for treatment. What type of infection transmission does the nurse understand occurred?
- A. Direct contact
- B. Droplet
- C. Airborne
- D. Vehicle
Correct Answer: A
Rationale: The route of transmission for a sexually transmitted disease is by direct contact. An infected person transmits the infection to a susceptible person. A droplet transmission is a spray of moist particles within a 3-foot radius of an infected person. An airborne transmission is suspension and transport on air currents beyond 3 feet. An infection transmitted by vehicle is on or in contaminated food, water, objects, or equipment.
A client visits the clinic reporting a circular rash on the upper right arm. The rash is diagnosed as tinea corporis. For what type of infection does the nurse anticipate the client will be treated?
- A. Rickettsiae
- B. Protozoans
- C. Mycoplasma
- D. Fungus
Correct Answer: D
Rationale: One type of fungal infection is superficial (dermatophytoses), which affect the skin, hair, and nails; examples include tinea corporis, or ringworm, and tinea pedis, also known as athlete's foot. Rickettsiae, protozoans, and mycoplasma have different characteristics and transmission than fungus.
The intensive care unit nurse is caring for a client with a transmissible spongiform encephalopathy. The nurse knows that this type of encephalopathy is caused by what type of infectious agent?
- A. Prion
- B. Protozoa
- C. Helminth
- D. Rickettsia
Correct Answer: A
Rationale: A prion is a protein that does not contain nucleic acid. Research suggests that normal prions present in brain cells protect against dementia. When a prion mutates, however, it is capable of becoming an infectious agent and altering other normal prion proteins into similar mutant copies. The mutant prions, which can be formed by genetic predisposition or acquired by transmission between the same or similar infected animal species, cause transmissible spongiform encephalopathies. Transmissible spongiform encephalopathies are not caused by protozoa, helminths, or rickettsias.
