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

Age 19 to 30 years.

Dark hair.

Female gender.

History of repeated sunburn.

Answer and Explanation

The Correct Answer is D

Choice A rationale

While individuals aged 19 to 30 years are generally at a lower risk for malignant melanoma compared to older adults, melanoma can still occur at any age, especially with certain risk factors. However, age alone does not significantly increase the risk of developing malignant melanoma without additional risk factors.

Choice B rationale

Hair color has minimal impact on the risk of developing malignant melanoma. Although individuals with fair skin and light hair have a higher risk of sunburn and subsequent melanoma, having dark hair does not significantly reduce the risk compared to other factors.

Choice C rationale

Female gender does not inherently increase the risk of developing malignant melanoma. Both males and females are at risk, although certain lifestyle factors and behaviors, such as sun exposure, can influence individual risk levels regardless of gender.

Choice D rationale

A history of repeated sunburn significantly increases the risk of developing malignant melanoma. Ultraviolet (UV) radiation from sunburns causes DNA damage in skin cells, leading to mutations that can result in melanoma. Repeated sunburns exacerbate this risk, making it a critical factor in melanoma development.

Correct Answer is A

Explanation

Choice A rationale

The electrical representations of the cardiac cycle that are documented by deflections on recording paper are known as an electrocardiogram (ECG). ECGs provide a visual record of the heart's electrical activity, captured through electrodes placed on the body. These deflections correspond to the depolarization and repolarization phases of the heart's muscle cells, translating into P, QRS, and T waves on the ECG strip. The primary function is to diagnose arrhythmias, myocardial infarction, and other heart conditions by identifying abnormal patterns in these waves.

Choice B rationale

This choice describes cardiac output, the amount of blood ejected from the left ventricle over one minute, which is unrelated to the visual documentation of electrical activity provided by an ECG.

Choice C rationale

This choice refers to the stroke volume, the amount of blood ejected with each heartbeat, not the electrical representation of cardiac activity shown on an ECG.

Choice D rationale

This choice is partially correct but does not fully describe an ECG, which includes a detailed recording on paper rather than just visual electrical impulses on a screen.

A. Scleroderma. B. Pedal erythema. C. Anasarca. D. Clubbing of the nails.

Correct Answer is D

Explanation

Choice A rationale

Scleroderma is a chronic autoimmune disorder characterized by hardening and tightening of the skin and connective tissues. While it affects the skin, it is unrelated to emphysema and bronchitis, making it an unlikely finding in this client.

Choice B rationale

Pedal erythema, or redness of the feet, can result from various causes, including infections, allergies, and circulatory issues. However, it is not commonly associated with emphysema and bronchitis, making it an unlikely finding in this client.

Choice C rationale

Anasarca is generalized body swelling due to fluid retention, often seen in severe heart failure, liver disease, and kidney failure. While this condition involves significant swelling, it is not typically linked to emphysema and bronchitis.

Choice D rationale

Clubbing of the nails is a common finding in chronic respiratory conditions like emphysema and bronchitis. It involves bulbous enlargement of the fingertips and nail curvature, resulting from prolonged low oxygen levels, making it a likely finding in this client.
