The nurse has contributed to a staff education program about the principles for the first tier of standard precautions. Which statement by a nursing student indicates a correct understanding of the teaching?
"All patients are presumed infectious."
"Isolation is not required for most diseases."
"Patients with a known infection are placed in isolation only when they are admitted."
"Patients are not considered infectious until confirmed so by the laboratory."
The Correct Answer is A
A. "All patients are presumed infectious.": This statement reflects the principle of universal precautions, which assumes that all patients may potentially transmit infectious agents, regardless of their diagnosis or symptoms. It emphasizes the importance of implementing infection prevention practices for every patient encounter to minimize the risk of transmission.
B. "Isolation is not required for most diseases.": While isolation precautions may not be required for all diseases, the statement does not fully capture the concept of universal precautions.
C. "Patients with a known infection are placed in isolation only when they are admitted.": This statement is not accurate as patients with known infections should be placed in isolation as soon as possible to prevent the spread of infection to others.
D. "Patients are not considered infectious until confirmed so by the laboratory.": Waiting for laboratory confirmation before implementing infection control measures could lead to delays in preventing transmission, as patients may be infectious before laboratory results are available.

Correct Answer is D
Explanation
A. Endogenous Infection: Endogenous infections originate from the client's own microbiota and typically do not involve medical interventions such as urinary catheterization.
B. Systemic Infection: Systemic infections affect the entire body and may not necessarily be related to the urinary tract.
C. Exogenous Infection: Exogenous infections originate from sources outside the client's body.
While the urinary tract infection could be caused by bacteria from the environment, it is more specifically categorized as a healthcare-associated infection (HAI) due to the indwelling urinary catheter being a risk factor.
D. Health Care-Associated Infection: A healthcare-associated infection (HAI) occurs as a result of healthcare interventions and can include infections related to urinary catheterization, surgery, or other medical procedures.
Correct Answer is B
Explanation
A. Normal white blood cell count: In wound sepsis, the white blood cell count is typically elevated as part of the body's immune response to infection, not normal.
B. Fever and chills: Fever (hyperthermia) and chills are common signs of systemic infection, including wound sepsis. They indicate an inflammatory response and activation of the body's defense mechanisms.
C. Decreased pain at the wound site: Increased pain at the wound site is more commonly associated with wound infection, not decreased pain.
D. Redness and swelling: Redness (erythema) and swelling (edema) are local signs of inflammation and can be present in infected wounds, but they are not specific to wound sepsis and may occur in non-infected wounds as well.
