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.
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 general survey is an overall assessment of a client's physical appearance, behavior, mobility, and neurological status. It provides a comprehensive overview of the client's health and well-being, making it the focus of the nurse's observations in this scenario.
Choice B rationale
Medical history includes past and current health conditions, surgeries, medications, and family health history. While important, it is not the focus of the nurse's immediate observations in this scenario.
Choice C rationale
Biographical data involves personal information such as age, gender, occupation, and marital status. While relevant to the client's health, it is not the primary focus of the nurse's observations in this scenario.
Choice D rationale
Social history includes information about the client's lifestyle, habits, and social environment. While valuable for understanding the client's overall health context, it is not the focus of the nurse's immediate observations in this scenario. .
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.
