Wearing a protective gown is about protecting yourself from contact with patient fluids. When there is excessive wound drainage, there’s a high chance you’ll come into contact with wound exudate during care activities, so a gown is worn as a barrier to protect your clothing and skin and to help prevent the spread of any pathogens. Fever, while it may indicate infection, doesn’t by itself require a gown for fluid exposure. Bradycardia is a heart-rate issue and not related to barrier precautions. Localized itching is a skin symptom with no direct risk of contact with wound fluids.

Choosing where to measure temperature depends on what the patient can tolerate and how accurate that reading needs to be. For an unconscious client, using the mouth isn’t possible, and sites that require precise placement or active cooperation can be unreliable or unsafe. The underarm route is safe, easy to access, and noninvasive, making it a practical choice in this situation for learning what a UAP can do. It provides a reasonable estimate of temperature without risking discomfort or injury from more invasive or technically demanding sites. Tympanic and temporal readings can be affected by placement, ear conditions, sweating, or movement, and they require careful technique to be reliable, which isn’t guaranteed in an unconscious patient or by a UAP without specialized training. Oral temperature is not feasible when the patient cannot cooperate, and relying on it would yield invalid results. While rectal measurements can be more accurate, they are invasive and typically reserved for trained staff or specific clinical indications, not routine UAP practice.

Barrel-shaped chest describes a front-to-back (AP) diameter that is increased so it closely matches the side-to-side (transverse) diameter, giving a round, widened appearance. This pattern is commonly seen in older adults due to aging-related changes in the chest wall and lungs, such as decreased elastic recoil and gradual hyperinflation, which roughen the chest’s contour and make the AP dimension more prominent. So describing a chest where the AP and transverse diameters are roughly equal fits this barrel shape. Pectus carinatum is a protruding sternum (pigeon chest)—a fixed deformity, not the aging-related barrel shape. Pectus excavatum (funnel chest) is a sunken sternum, another distinct deformity. These do not describe the barrel-like, increased AP diameter seen with aging.

Dry skin happens when the skin’s protective barrier is disrupted and moisture escapes more easily. Cleansing products that remove natural oils are a common cause, and hard soap is particularly effective at this because it is more alkaline and harsher on the skin than mild cleansers. That harsher cleansing disrupts the lipids in the outer skin layer, increasing transepidermal water loss and leaving the skin dry, tight, and rough. Cold weather and frequent bathing can also contribute to dryness, but the cleansing agent’s properties make hard soap the most impactful factor among the options. High humidity tends to keep skin moisturized, not dry.
