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.
