The nurse is collecting a culture of a wound. During the procedure, the patient asks what is a culture? Which of the following is the best response by the nurse to explain why she is culturing the wound?

"A culture identifies an antibiotic's effect on a pathogen."

"A culture determines the appropriate medication dose."

"A culture measures antibiotic levels."

"A culture identifies the presence of pathogens."

Answer and Explanation

The Correct Answer is D

A.   "A culture identifies an antibiotic's effect on a pathogen.": Cultures do not determine the effect of antibiotics on pathogens; they identify the presence of pathogens and their susceptibility to antibiotics.
B.   "A culture determines the appropriate medication dose.": Cultures do not determine medication doses; they identify pathogens and guide antibiotic selection based on susceptibility testing.
C.   "A culture measures antibiotic levels.": Cultures do not measure antibiotic levels; they identify pathogens and their susceptibility to antibiotics.
D.   "A culture identifies the presence of pathogens.": This is the correct explanation. A wound culture is performed to identify any microorganisms present in the wound, such as bacteria or fungi, which helps guide appropriate treatment.

Correct Answer is C

Explanation

A. Document the client's history of skin allergies: While important for the client's overall care, documenting the history of skin allergies is not the priority when assessing a new skin lesion.
B. Photograph the lesion for the client's medical record: Documenting the appearance of the lesion is important for the client's medical record, but it is not the priority when initially assessing the lesion.
C. Identify when the client first noticed the lesion: The priority is to gather information about the onset and characteristics of the lesion to determine its potential severity and urgency of intervention.
D. Instruct the client on the use of daily sunscreen products: While sun protection is important for skin health, it is not the priority when assessing a new skin lesion.

A. Perform hand hygiene before, during, and after direct contact with the client B. Encourage the client to consume a diet high in protein C. Change the client's bed linens each day D. Place the client in a room with positive pressure airflow

Correct Answer is A

Explanation

A. Perform hand hygiene before, during, and after direct contact with the client: Hand hygiene is one of the most effective strategies to interrupt the transmission of infections. It helps prevent the spread of pathogens from one person to another, reducing the risk of healthcare-associated infections.
B. Encourage the client to consume a diet high in protein: While proper nutrition is important for overall health and immune function, it does not directly address the transmission of the client's infection.

C. Change the client's bed linens each day: Changing bed linens regularly is important for maintaining cleanliness and comfort but is not sufficient to interrupt the transmission of infection.

D. Place the client in a room with positive pressure airflow: Positive pressure airflow rooms are typically used for patients with compromised immune systems to protect them from airborne pathogens. This strategy is not applicable for all types of infections and may not be necessary for every client with an infection.
