The student nurse knows that an older client's skin is most likely to experience which of the following changes with aging?

Thickening of the epidermis.

Thinning of the epidermis.

Oiliness of the skin.

Increased elasticity of the skin.

Answer and Explanation

The Correct Answer is B

A.   Thickening of the epidermis: The epidermis tends to thin rather than thicken with aging.
Thinning of the epidermis can lead to increased vulnerability to injury and slower wound healing.
B.   Thinning of the epidermis: Thinning of the epidermis is a common age-related change in the skin. This thinning can result in a decreased barrier function, making the skin more susceptible to damage and infection.
C.   Oiliness of the skin: Older adults often experience a decrease in oil production, leading to drier skin rather than oilier skin.
D.   Increased elasticity of the skin: With aging, the skin tends to lose elasticity, resulting in sagging and wrinkles rather than increased elasticity.

Correct Answer is C

Explanation

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. "A culture identifies an antibiotic's effect on a pathogen." B. "A culture determines the appropriate medication dose." C. "A culture measures antibiotic levels." D. "A culture identifies the presence of pathogens."

Correct Answer is D

Explanation

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.
