The nurse is teaching a health promotion class for adults about the effects of sun exposure on skin. Which statement about the function of collagen is correct?
It is the main structural component of the dermis which provides strength and elasticity.
It increases skin elasticity with the aging process.
It forms the ridges and valleys which provide traction for grasping objects and surfaces.
It is an extensive network of blood vessels that regulates body temperature.
The Correct Answer is A
A. It is the main structural component of the dermis which provides strength and elasticity. Collagen is the primary protein in the dermis, responsible for maintaining skin strength, firmness, and elasticity. Sun exposure damages collagen fibers, leading to wrinkles, sagging skin, and premature aging.
B. It increases skin elasticity with the aging process. Collagen production decreases with age, leading to reduced skin elasticity and increased wrinkle formation. Sun damage accelerates this process by breaking down collagen fibers.
C. It forms the ridges and valleys which provide traction for grasping objects and surfaces. Friction ridges (fingerprints) are formed by the dermal papillae, not collagen. They provide grip and are genetically determined.
D. It is an extensive network of blood vessels that regulates body temperature. The dermis contains a network of blood vessels for temperature regulation, but this function is not related to collagen. Instead, collagen provides structural support to the skin.

Correct Answer is D
Explanation
A. Has hyperemia at the site of an acute local infection. Hyperemia (increased blood flow) is a sign of the body's normal immune response to infection. While the client has an infection, their immune system is still active, making them less vulnerable to new healthcare-associated infections (HAIs) compared to an immunosuppressed individual.
B. Recently received a series of adult immunizations. Vaccinations enhance the immune system and help protect against infections. This does not increase the risk of developing an HAI.
C. Lost ten pounds adhering to a low carbohydrate diet. Dietary changes alone do not significantly impact infection risk unless they lead to malnutrition. A 10-pound weight loss does not necessarily indicate a compromised immune system.
D. Receiving immune suppressant therapy for cancer. Immunosuppressive therapy weakens the immune system, making the client highly susceptible to HAIs. Cancer treatments, such as chemotherapy, radiation, or corticosteroids, reduce the body's ability to fight infections, increasing the risk of hospital-acquired infections like pneumonia, bloodstream infections, and surgical site infections.
Correct Answer is []
Explanation
Potential Condition:
Diabetic neuropathy – The client has a history of type 1 diabetes, and her elevated Hemoglobin A1C (8.2%) suggests poor blood glucose control, which increases the risk of diabetic neuropathy.
Actions to Take:
Perform a sensory test on both feet – Diabetic neuropathy can cause loss of sensation in the feet. A sensory test helps assess nerve function and detect early signs of neuropathy.
Instruct the client to change to clean, dry socks – Proper foot care is crucial for preventing infections and complications in clients with diabetes. Keeping feet dry reduces the risk of skin breakdown and infections.
Parameters to Monitor:
Pedal pulses – Poor circulation is a common complication of diabetes and neuropathy. Monitoring pedal pulses helps assess blood flow to the feet.
Blood glucose – Tight glucose control is essential for preventing the progression of diabetic neuropathy. Monitoring blood glucose levels helps guide management and treatment adjustments.
