A nurse is assessing a client at a dermatology clinic. Which of the following findings places the client at risk for developing malignant melanoma?

Dark hair

Female gender

History of chronic skin irritation

Age 19 to 30 years

Answer and Explanation

The Correct Answer is C

Choice A reason:
Dark hair is not a recognized risk factor for developing malignant melanoma. Melanoma is more commonly associated with individuals having fair skin, light hair, and light-colored eyes because they have less melanin to protect their skin from UV radiation.

Choice B reason:
While female gender is not a direct risk factor for malignant melanoma, it is important to note that melanoma rates can vary between genders at different ages. Generally, before age 50, melanoma rates are higher in women, but by age 65, rates are twice as high in men.

Choice C reason:
A history of chronic skin irritation or inflammation can potentially increase the risk of developing skin cancer, including melanoma. Chronic inflammation can lead to DNA damage and contribute to the development of cancerous cells.

Choice D reason:
Age 19 to 30 years is not considered a high-risk age group for malignant melanoma. The risk of melanoma increases with age, and it is most frequently diagnosed in older adults, although it is not uncommon in younger people.

Correct Answer is D

Explanation

Choice A reason:
It is important to keep a Plaster of Paris cast dry because moisture can weaken the cast and irritate the skin underneath. Therefore, the cast should be covered while showering to prevent it from getting wet.

Choice B reason:
Applying ice to the foot after walking can help reduce swelling and provide pain relief. It is a common recommendation for managing discomfort associated with a walking cast. The ice should be applied over the cast at the level of the injury for 15-30 minutes, repeating every few hours for the first few days.

Choice C reason:
While a musty odor can develop over time due to sweat and lack of air circulation, it is not necessarily normal and could indicate a problem such as an infection. If there is a persistent unpleasant odor, it should be evaluated by a healthcare provider.

Choice D reason:
Numbness or pain in the toes can be a sign of compromised circulation or nerve compression and should be reported immediately. It is crucial to monitor for any changes in sensation or increased pain, as these could indicate a serious issue that requires medical attention.

A. Hay fever allergy B. Anaphylaxis C. Transplant rejection D. Bacterial phagocytosis

Correct Answer is C

Explanation

Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.

Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.

Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.

Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.
