A nurse is caring for a client who has a stage 3 pressure ulcer. The nurse should recognize that which of the following laboratory findings will affect wound healing?
Hemoglobin 16g/dL
INR 0.9
Serum albumin 3.2 g/dL
WBC count 8,000/mm
The Correct Answer is C
Choice A rationale: Hemoglobin level reflects the oxygen-carrying capacity of the blood but is not a direct indicator of nutritional status.
Choice B rationale: International Normalized Ratio (INR) is a measure of blood clotting, and a normal value does not directly impact wound healing.
Choice C rationale: Serum albumin is a marker of nutritional status, and a low level (hypoalbuminemia) can adversely affect wound healing. Adequate protein intake is essential for collagen synthesis and overall tissue repair.
Choice D rationale: White blood cell count is an indicator of immune response and infection but does not directly affect wound healing in the absence of infection.

Correct Answer is C
Explanation
Choice A rationale: Actinic keratosis presents as rough, scaly patches on sun-exposed skin and is not associated with the purplish-brown lesions seen in Kaposi's sarcoma.
Choice B rationale: Basal cell carcinoma typically presents as pearly or waxy bumps and is not characterized by widespread purplish-brown lesions.
Choice C rationale: Kaposi's sarcoma is characterized by the development of purplish-brown skin lesions, and it is commonly associated with advanced HIV/AIDS.
Choice D rationale: Toxic epidermal necrolysis is a severe skin reaction but is not typically associated with purplish-brown lesions.
Correct Answer is A
Explanation
Choice A rationale: the epidermis becomes thinner and more fragile with age hence making the skin of elderly individuals more prone to injury, bruising, and infections.
Choice B rationale: this is incorrect because the skin in old age loses its elasticity and becomes more wrinkled due to the loss of collagen and elastin fibers responsible for maintaining the elasticity of the skin.
Choice C rationale: subcutaneous tissue comprising mainly of fat and connective tissue increases with age especially in regions such as the abdomen.
Choice D rationale: blood vessels within the skin become narrower and less efficient with increasing age thus resulting in decreased blood flow and oxygen delivery to the skin.
Choice E rationale: sebum production which is responsible for skin lubrication increases with age thus making this statement incorrect.
