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 D

Explanation

A. Pupil size and reaction: Pupil size and reaction are typically assessed to monitor neurological function and are not directly related to tissue integrity.
B. Heart rate and blood pressure: Heart rate and blood pressure are vital signs that provide information about cardiovascular function but do not specifically assess tissue integrity.
C. Respiratory rate and oxygen saturation: Respiratory rate and oxygen saturation are indicators of respiratory function and oxygenation status and are not directly related to tissue integrity.
D. Skin turgor and moisture: Skin turgor, the skin's ability to return to its normal shape after being pinched, and moisture levels are important assessments for monitoring tissue hydration and integrity. Changes in skin turgor and moisture can indicate dehydration, which can impair tissue integrity and wound healing.

A. To relieve itching or discomfort B. To improve the appearance of the skin C. To remove a suspicious lesion D. To treat a skin infection

Correct Answer is C

Explanation

A. To relieve itching or discomfort: Skin biopsies are not typically performed to relieve itching or discomfort. Other treatments, such as topical medications or systemic therapies, may be used for symptomatic relief.
B. To improve the appearance of the skin: Skin biopsies are not performed for cosmetic purposes. They are diagnostic procedures used to obtain tissue samples for examination under a microscope to diagnose or rule out various skin conditions.
C. To remove a suspicious lesion: Skin biopsies are commonly performed to remove suspicious lesions, such as moles, growths, or areas of abnormal skin, for further evaluation and diagnosis.
This helps determine if the lesion is benign or malignant and guides subsequent treatment decisions.
D. To treat a skin infection: Skin biopsies are not performed as a primary treatment for skin infections. Biopsies are diagnostic procedures used to obtain tissue samples for analysis and are not typically indicated for treating infections.
