When assessing an older adult client, the nurse notes which age-related changes of the cardiovascular system that increase the risk for falls?

A) 2: A muscle strength grade of 2 indicates that the muscle can move when gravity is eliminated, such as when the limb is supported. However, it does not have enough strength to move against gravity. This grade is not appropriate for the client described, as they can move both lower legs against gravity.
B) 3: A muscle strength grade of 3 means that the muscle can move the joint against gravity but without any additional resistance. This is less than the client’s described ability, as they can move their legs against some resistance.
C) 4: A muscle strength grade of 4 indicates that the muscle can move against gravity and moderate resistance. This matches the client’s ability to actively move both lower legs against gravity and some resistance, making it the correct documentation of their muscle strength.
D) 5: A muscle strength grade of 5 indicates normal muscle strength, where the muscle can move against gravity and full resistance without any signs of fatigue. Since the client is described as moving against some resistance but not full resistance, a grade of 5 would overestimate their current muscle strength.

A) Asymmetrical shape: One of the key "ABCD" characteristics of malignant melanoma is asymmetry. Melanomas often have an irregular shape where one half does not match the other, unlike benign moles, which are typically symmetrical. This characteristic helps in distinguishing malignant lesions from benign ones.
B) Diameter less than 6mm: Malignant melanomas are often larger than 6 mm in diameter, especially as they progress. While smaller lesions can still be malignant, a diameter less than 6 mm is not a distinguishing feature for melanoma. Typically, melanomas are identified as growing larger over time.
C) Color is uniform: Malignant melanomas usually exhibit multiple colors or uneven pigmentation rather than uniform color. Uniform color is more characteristic of benign moles. Melanomas can show a mix of colors, including shades of brown, black, and sometimes red or white.
D) Borders well demarcated: Malignant melanoma often has irregular, not well-defined borders. The edges of a melanoma are usually uneven or not clearly defined, unlike benign moles, which typically have smooth, well-demarcated borders.
