  11. The large, heavy, and older adult patient, post stroke, develops an infected decubitus on the sacrum during the hospital stay. When the patient goes home, about 2 weeks later, the patient returns to the hospital with pneumonia. The distinction between these two infections is which of the following?

    A. The decubitus is considered to be caused by protozoa, whereas the pneumonia is termed unpreventable because of the size of the patient.
    B. The decubitus and pneumonia are caused by the same host.
    C. The decubitus infection was transmitted from other patients on the unit, but the pneumonia was transmitted from a neighbor visiting when the patient was at home.
    D. The decubitus is termed nosocomial and the pneumonia is termed community-acquired.
    D. Because the decubitus developed during the stay in a health care facility, it is classified as nosocomial. Because the patient did not have pneumonia when he left the facility, it is classified as community-acquired.

  12. The home health nurse, on a visit to administer the fifth in a series of 10 antibiotic doses, is told that the patient is now complaining about a bothersome vaginal discharge. The nurse will communicate the problem to arrange for medication and teaches the patient that this condition is probably the result of:

    A. allergy to the soap, or soap products, used in the area.
    B. poor genital hygiene—not changing underwear often enough.
    C. superinfection response to the antibiotic.
    D. sexual contact with another infected person.

    B. “Take the child who is not sick to her own doctor and ask this question first.”
    C. “No, the child should not visit. Infectious diseases are often most communicable in the short period before the child actually becomes ill.”
    D. “Yes, let the child visit. There is no reason not to visit, because this child is not sick.”
    C. Children, especially those who have been exposed to a contagious disease but are not yet symptomatic, are still very contagious, especially to the immunocompromised patient.

  20. The patient receiving a large IM dose of antibiotic was asked to please wait 20 to 30 minutes before checking out. The reason for this request is that:

    A. antibiotics are a common source of severe allergic reactions within the first few minutes after injection.
    B. the office staff needs to make sure that it was the right medicine before the patient leaves.
    C. the staff wants to make sure that the patient has time to pay for the services delivered that day.
    D. the nurse always forgets to ask patients about allergies before administering the antibiotic.
    A. Antibiotic administration is a common cause of anaphylaxis. The patient is asked to wait so that if this condition occurs, the patient will be with medical personnel to reverse it.

  27. The school nurse is required to report to the health department all cases of (select all that apply):

    1. rubella.
    2. Lyme disease.
    3. pediculosis.
    4. salmonella.
    5. Clostridium difficile.
    • 1, 2, 4
    • Rubella, Lyme disease, and salmonella are all reportable. Lice and Clostridium difficile are not reportable.
  28. The nurse assesses a high eosinophil count in a pediatric patient. The nurse recognizes that this elevation is an indicator of ____________________.
  29. Persons with HIV have fallen victim to PCP, Pneumocystis jiroveci, a serious pulmonary infection caused by a ____________________.
  30. The nurse reminds the patient who is to undergo hyperbaric oxygen therapy that the clothing worn into the chamber must be made of ____________________.
  31. Prioritize the events of an antibody-mediated immunity response.

    1. Antibodies seek out and bind with specific antigen.
    2. Antigen binds to a B lymphocyte.
    3. Circulating antibody-antigen complexes are destroyed.
    4. Antibodies are produced.
    5. Antibodies are replenished.
    • 2, 4, 1, 3, 5
    • Antigen binds to a B lymphocyte and antibodies are produced for that specific antigen. Antibodies seek out and bind with the specific antigen when it is reintroduced to the organism and bind with them. These circulating antigen-antibody complexes are targeted and destroyed by phagocytes. Antibodies are continually replenished in most cases.
