A nurse is working in a dermatology clinic. The provider orders a skin biopsy, and you need to educate the client on the purpose of a skin biopsy. Which of the following is indicative of a skin biopsy?

To relieve itching or discomfort

To improve the appearance of the skin

To remove a suspicious lesion

To treat a skin infection

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

A. Potassium: Potassium levels are not typically used to diagnose infection. Elevated potassium levels may indicate other health conditions such as kidney dysfunction.
B. BUN (Blood Urea Nitrogen): BUN levels assess kidney function and are not directly related to the presence of infection.
C. WBC count (White Blood Cell count): An elevation in the WBC count, specifically the neutrophil count (neutrophilia), is indicative of the body's response to infection or inflammation.
D. RBC count (Red Blood Cell count): RBC count is not typically used to diagnose infection.
Elevated RBC count may indicate conditions such as dehydration or polycythemia.

A. "All patients are presumed infectious." B. "Isolation is not required for most diseases." C. "Patients with a known infection are placed in isolation only when they are admitted." D. "Patients are not considered infectious until confirmed so by the laboratory."

Correct Answer is A

Explanation

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.
