-Effects...

Question 2

Which of the following was the blood test for syphilis that was required for all couples about to be married in an effort to identify and treat infected people before they could transmit the disease to a child?

Accepted Answer

The Wasserman test was historically used as a blood test for syphilis and was required for couples before marriage to prevent transmission of the disease.

Question 3

What medical condition was identified as the cause of mental retardation in a significant number of institutionalized adults?

Accepted Answer

Phenylketonuria (PKU) is a genetic disorder caused by a deficiency in the enzyme phenylalanine hydroxylase. This deficiency leads to an accumulation of phenylalanine in the body, which can cause intellectual disability if not treated early with a special diet. PKU was identified as a significant cause of mental retardation in institutionalized individuals before widespread newborn screening and dietary treatments were implemented.

Question 4

What method of laboratory testing searches for more than 20 metabolic disorders in one process, using the dried blood-spot specimen?

Accepted Answer

Tandem mass spectroscopy is used to screen for over 20 metabolic disorders in a single process using dried blood-spot specimens, making it a highly efficient and comprehensive testing method in newborn screening programs.

Question 5

Much more is known about the disruptions of fetal development that lead to birth defects than is known about carcinogenesis.

Accepted Answer

While significant research has been conducted on both fetal development and carcinogenesis, the complexities of cancer development (carcinogenesis) are generally better understood due to extensive research over many decades.

Question 6

Teratogens are limited to physical and chemical factors such as radiation and carcinogenic compounds.

Accepted Answer

Teratogens include a variety of substances and conditions such as drugs, alcohol, certain diseases, and environmental factors, not just physical and chemical factors.

Question 7

Decades ago, many states required blood tests for syphilis before a marriage license could be granted.

Accepted Answer

Many states in the United States once mandated blood tests for syphilis as a prerequisite for obtaining a marriage license, primarily to prevent the spread of this sexually transmitted infection. This practice has largely been phased out.

Question 8

Maternal infection with rubella during pregnancy can cause deafness in children.

Accepted Answer

Rubella infection during pregnancy, especially during the first trimester, can lead to congenital rubella syndrome in the child, which includes a range of birth defects such as deafness, heart defects, and developmental delays.

Question 9

Alcohol has been recognized as a teratogen since the 1970s.

Accepted Answer

Alcohol was recognized as a teratogen, which is a substance that can cause birth defects, in the early 1970s following studies and observations that linked prenatal alcohol exposure to a range of developmental disorders, now known as Fetal Alcohol Spectrum Disorders (FASD).

Question 10

In ultra-orthodox communities that practice arranged marriage, a confidential registry was established that allows matchmakers to avoid arranging marriages between carriers of Tay-Sachs and several other debilitating.

Accepted Answer

In some ultra-orthodox Jewish communities, a confidential registry known as Dor Yeshorim was established to screen for Tay-Sachs disease and other genetic disorders. This helps prevent arranged marriages between carriers of these conditions, thereby reducing the incidence of affected offspring.
