Which body system has the highest risk of congenital anomaly in a child with Down syndrome?

Genitourinary system.

Reproductive system.

Gastrointestinal system.

Cardiovascular system.

Answer and Explanation

The Correct Answer is D

Choice A rationale

While the genitourinary system can be affected in individuals with Down syndrome, it is not the most commonly affected body system. Down syndrome is a genetic condition where a person is born with an extra chromosome. This can affect how their brain and body develop, leading to both physical and mental challenges.

Choice B rationale

The reproductive system is not the most commonly affected body system in individuals with Down syndrome. While individuals with Down syndrome can have reproductive health issues, these are not as common as issues with other body systems.

Choice C rationale

The gastrointestinal system can be affected in individuals with Down syndrome, but it is not the most commonly affected body system. Some individuals with Down syndrome may experience gastrointestinal issues such as constipation or gastroesophageal reflux disease.

Choice D rationale

The cardiovascular system is the most commonly affected body system in individuals with Down syndrome. Almost half of babies with Down syndrome have congenital heart disease (CHD), the most common type of congenital anomaly. CHD can lead to high blood pressure in the lungs, an inability of the heart to effectively and efficiently pump blood, and cyanosis (blue-tinted skin caused by reduced oxygen in the blood)3.

Correct Answer is B

Explanation

Choice A rationale

Measuring from the back of the head to the forehead is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.

Choice B rationale

Placing the measuring tape above the eyebrows and around the widest part of the head is the correct method for measuring head circumference in an infant. The tape should be wrapped around the head at the points just above the eyebrows, above the ears, and around the back where the head slopes up prominently from the neck.

Choice C rationale

Measuring from the chin to the top of the head is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.

Choice D rationale

Wrapping the measuring tape tightly around the neck is not the correct method for measuring head circumference in an infant. The measurement should be taken around the widest part of the head, which is typically above the eyebrows and ears.

A. 3 months. B. 6 months. C. 9 months. D. 12 months.

Correct Answer is B

Explanation

Choice A rationale

While some babies may experience rapid growth and double their birth weight within the first 3 months, this is not typically expected. Most infants are expected to double their birth weight by 5 to 6 months of age.

Choice B rationale

Most infants are expected to double their birth weight by 5 to 6 months of age. Therefore, by the age of 6 months, it would be expected for an infant to have doubled their birth weight.

Choice C rationale

By 9 months, most infants would have already doubled their birth weight. The typical expectation is for infants to double their birth weight by 5 to 6 months of age.

Choice D rationale

By 12 months, most infants would have already doubled their birth weight and are on their way to tripling their birth weight. Therefore, expecting an infant to double their birth weight by 12 months would be beyond the typical timeframe.
