The nurse is taking a health history for a patient who is ill in the emergency room. The patient states that he has not been around anyone that has been sick lately. The nurse suspects the patient likely contracted the illness by indirect transmission. Which is an example of this type of transmission?
Utilizing a friend's computer keyboard.
Talking directly to someone coughing.
Standing next to a person with a varicella (chickenpox) infection.
Walking past an individual coughing and sneezing.
The Correct Answer is A
A. Utilizing a friend's computer keyboard: Indirect transmission occurs when pathogens are transmitted via inanimate objects, such as keyboards, doorknobs, or utensils. If the friend's computer keyboard is contaminated with pathogens, the patient could contract an illness by touching it.
B. Talking directly to someone coughing: This is an example of direct transmission, where pathogens are transmitted through close contact with an infected person's respiratory secretions.
C. Standing next to a person with a varicella (chickenpox) infection: This is an example of direct transmission, as varicella is spread through respiratory droplets.
D. Walking past an individual coughing and sneezing: This is also an example of direct transmission, as respiratory droplets containing pathogens can land on the nurse and lead to infection if inhaled or touched.

Correct Answer is B
Explanation
A. A person with diabetes who requires hospitalization for cellulitis: Cellulitis may not necessarily be a healthcare-associated infection unless it developed as a complication during the hospitalization.
B. Pneumonia in a hospitalized patient: Pneumonia acquired during a hospital stay is considered a healthcare-associated infection (HAI) because it develops after 48 hours of hospital admission.
C. Chronic urinary tract infection for a homebound patient: A chronic urinary tract infection in a homebound patient is not automatically considered a healthcare-associated infection unless it can be directly linked to healthcare interventions or devices.
D. A sexually transmitted infection in a healthy young adult: Sexually transmitted infections are not healthcare-associated infections as they are typically acquired through sexual contact rather than healthcare settings.
Correct Answer is B
Explanation
A. Place a N95 mask on the patient: Tuberculosis (TB) is an airborne infectious disease, and N95 masks are specifically designed to filter out airborne particles, including those that may carry TB bacteria. Therefore, placing an N95 mask on the patient helps prevent the spread of TB to others during transportation.
B. Place a surgical mask on the patient: While a surgical mask may provide some level of
protection, it is not as effective as an N95 mask in filtering out airborne particles, particularly those associated with TB transmission.
C. Be sure the patient is wearing a protective gown: Protective gowns are typically used to
prevent the transmission of infection through contact with body fluids or contaminated surfaces. However, in the case of TB, airborne precautions, including respiratory protection with masks, are more crucial.
D. Instruct the patient to wear gloves to radiology: Gloves are not necessary for respiratory protection against TB during transportation to radiology.
