Choice C: Vascular spiders are dilated blood vessels that appear on the skin as red or purple spider-like lesions. They are caused by increased estrogen levels and blood volume during pregnancy. They are usually found on the face, neck, chest, or arms.

Correct Answer is A

Explanation

Choice A Reason: Trisomy numeric abnormality. Down syndrome is a genetic disorder that occurs when a person has three copies of chromosome 21 instead of two. This extra chromosome causes various physical and mental features that vary from person to person. Down syndrome is also called trisomy 21 because it involves three copies of chromosome 21.

Choice B Reason: Multifactorial inheritance is incorrect because it refers to a type of genetic disorder that results from the interaction of multiple genes and environmental factors. Examples of multifactorial disorders include cleft lip or palate, neural tube defects, diabetes, hypertension, and some types of cancer.

Choice C Reason: X-linked recessive inheritance is incorrect because it refers to a type of genetic disorder that affects males more than females because it is caused by a mutation on the X chromosome. Females have two X chromosomes, so they can be carriers or affected depending on whether they inherit one or two copies of the mutated gene. Males have one X chromosome and one Y chromosome, so they are always affected if they inherit the mutated gene from their mother. Examples of X-linked recessive disorders include hemophilia, color blindness, and Duchenne muscular dystrophy.

Choice D Reason: Chromosomal deletion is incorrect because it refers to a type of genetic disorder that occurs when a part of a chromosome is missing or deleted. This can cause various physical and mental problems depending on the size and location of the deletion. Examples of chromosomal deletion

A. linea nigra B. pica C. ballottement D. quickening

Correct Answer is B

Explanation

Choice A Reason: Linea nigra is a dark vertical line that appears on the abdomen of some pregnant women. It is caused by increased melanin production and usually fades after delivery.

Choice B Reason: Pica is a condition in which a person has an abnormal desire to eat substances that are not food, such as ice, clay, dirt, or chalk. It is more common in pregnant women and may indicate a deficiency in iron or other nutrients.

Choice C Reason: Ballottement is a technique of palpating a floating structure by bouncing it gently and feeling it rebound. In obstetrics, it can be used to detect the presence of the fetus by feeling its head move when the cervix is tapped.

Choice D Reason: Quickening is the first perception of fetal movements by the pregnant woman. It usually occurs between 16 and 20 weeks of gestation.
