Increased lumbar curvature, which compensates for the enlarging uterus in pregnant women, is called what?

Lordosis

Kyphosis

Keratosis

Scoliosis

Answer and Explanation

The Correct Answer is A

A) Lordosis: Lordosis refers to an increased inward curvature of the lumbar spine. During pregnancy, this curvature often increases to help compensate for the growing uterus and shift the center of gravity. This adjustment helps maintain balance and alignment but can lead to noticeable changes in posture.
B) Kyphosis: Kyphosis is characterized by an exaggerated outward curvature of the thoracic spine, resulting in a hunchback appearance. It is not related to the increased lumbar curvature seen during pregnancy.
C) Keratosis: Keratosis refers to a condition involving thickening or hardening of the skin, such as actinic keratosis. It is unrelated to spinal curvature or changes associated with pregnancy.
D) Scoliosis: Scoliosis is a condition marked by an abnormal lateral curvature of the spine. It does not specifically relate to the increased lumbar curvature that occurs during pregnancy due to the enlarging uterus.

Correct Answer is A

Explanation

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.

A. the tricuspid area. B. Erb's point. C. the mitral area. D. the aortic area.

Correct Answer is D

Explanation

A) The tricuspid area: The tricuspid area is located at the lower left sternal border, around the 4th or 5th intercostal space. It is where the tricuspid valve sounds are best heard, not the area for auscultating the 2nd rib space.
B) Erb's point: Erb's point is located at the left sternal border in the 3rd intercostal space. It is a key area for auscultating both the aortic and pulmonic valves, as well as the mitral and tricuspid valves, but it is not associated with the right 2nd rib space.
C) The mitral area: The mitral area, also known as the mitral valve area, is located at the 5th intercostal space at the midclavicular line on the left side. This area is used for auscultating the mitral valve, not the right 2nd rib space.
D) The aortic area: The right 2nd rib space, also known as the 2nd intercostal space at the right sternal border, is the location where the aortic valve sounds are best auscultated. This area is used to listen to the aortic valve's closure and is the first location for cardiac auscultation.
