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.

A. Polymeric membrane dressing B. Hydrofiber dressing C. Hydrogel dressing D. Hydrocolloid dressing

Correct Answer is B

Explanation

Choice A rationale: this is a type of non-adherent dressing that can be used for wounds with minimal exudates hence this is not suitable for wounds with significant exudate since it causes maceration and leakage.
Choice B rationale: this is an absorbent dressing that can be used in wounds with moderate-significant exudate since it moistens the wound environment while facilitating autolytic debridement by forming a gel in contact with the exudate.
Choice C rationale: this is a type of hydrating dressing containing water or glycerin-based gel that is suitable for use in wounds with minimal exudate.
Choice D rationale: this is a type of occlusive dressing suitable for wounds with minimal-moderate exudates. It is unsuitable for wounds with significant exudate since it can result in maceration and leakage.
