After teaching a client who has a stage 2 pressure injury, a nurse assesses the client's understanding.
Which dietary choice by the client indicates a good understanding of the teaching?

Choice A rationale

There is no conclusive scientific evidence to support the claim that specific foods like chocolate, peanuts, and cola directly cause or worsen acne. Acne is a multifactorial condition primarily driven by hormonal changes, sebum production, follicular hyperkeratinization, and the bacteria Propionibacterium acnes. While a high glycemic diet may be linked to acne, there is no direct causal link with these specific foods.

Choice B rationale

Over-washing the face with harsh cleansing products can strip the skin of its natural oils (sebum), leading to a rebound effect where the sebaceous glands produce even more oil. This can exacerbate acne by creating a more favorable environment for bacterial proliferation and follicular clogging. Gentle cleansing twice a day is recommended, not frequent washing, to maintain skin barrier integrity.

Choice C rationale

Moderate sun exposure can be beneficial for some individuals with acne. Ultraviolet (UV) light has anti-inflammatory and antibacterial properties that can reduce the population of Propionibacterium acnes. Avoiding sun exposure completely is not a standard recommendation for acne prevention, although excessive sun exposure can lead to other skin problems and should be avoided.

Choice D rationale

Stress and lack of rest can increase cortisol levels, which can stimulate sebum production and inflammation, contributing to acne formation. A balanced diet provides essential vitamins and minerals for skin health, and sufficient rest helps regulate hormonal balance. Promoting overall well-being through diet and rest indirectly supports skin health and can help in the prevention of acne.

Choice A rationale

Infant skin has greater perfusion compared to adult skin due to a higher ratio of capillaries to surface area. This increased blood flow contributes to the infant's ability to dissipate heat but also makes their skin more susceptible to flushing and temperature changes.

Choice B rationale

While infants have a higher percentage of total body water, their stratum corneum, the outermost layer of skin, is thinner and has a lower lipid content, leading to a higher transepidermal water loss compared to adults. This makes their skin more prone to dryness.

Choice C rationale

Infants have a higher density of eccrine sweat glands, but their thermoregulatory system is immature. They are less efficient at perspiring and have a higher risk of hyperthermia. Their sweat glands are not fully developed or functional, which is different from increased perspiration.

Choice D rationale

Infant skin has a thinner stratum corneum and a higher surface area-to-weight ratio compared to adult skin. This anatomical difference results in a greater percutaneous absorption of topical medications and other substances. This is why care must be taken with the amount of medication applied.
