In which order does humoral immunity react when stimulated by an invading foreign antigen?
1) B lymphocytes become sensitized to foreign antigen. 2) Complement assists with antibody attachment to antigen. 3) White cells destroy antigen-antibody immune complexes 4) Memory cells are synthesized for future antigen recognition.
Which statement by a patient can the nurse determine indicates the need for further teaching about a prescribed anti-infective medication?
“I can miss a dose as long as I take it the next time the dose is due.”
Which statement by the patient on droplet precautions indicates understanding of how to prevent the spread of infection?
“I’ll cover my mouth whenever coughing or sneezing.”
Which action will the nurse take when caring for a patient with drug-resistant Clostridium difficile (C-Diff) to prevent spreading the infection to other patients?
Teach the patient to wash hands after toileting.
Which intervention does the nurse determine addresses the collaborative goal of “eradication of the pathogenic agent”?
Oseltamivir prescribed for influenza
Which actions will the nurse avoid to prevent indirect transmission of pathogens when caring for a patient with an infection?
Handling medical equipment, hanging patient linens, Removing food trays, Disposing of tissues
Which patient findings does the nurse determine to report to the provider because they indicate progression of the patient’s infection to sepsis?
Change in mental status to mild disorientation, Heart rate 102 beats per minute, Urine output to less than 30 mL/hour, Cold, clammy skin with pale appearance
Which humoral immune events separate it from cell-mediated immunity?
Recognition of antigen non-self-markers, B lymphocytes releasing specific antibodies, Binding of antibodies to foreign antigens,Chemotaxis from immune complex formation
Match the situation with its definition.
Isolation-Separates those with disease from those without disease, Quarantine- Restricts movement of those exposed to an infectious agent, Protective isolation- Prevents exposure of person with compromised immunity from others
Match the type of immunity with the source from which it is obtained.
