When assessing the knowledge of new parents of a child born with Maple Syrup Urine Disease (MSUD), an autosomal recessive inherited disorder, which statement is true?

Only one copy of the abnormal gene is required for the disorder to be expressed.

The disorder is carried on the X chromosome.

Both genes of a pair must be abnormal for the disorder to be expressed.

The disorder occurs in males and heterozygous females.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Incorrect. This statement describes autosomal dominant inheritance, not autosomal recessive inheritance. In autosomal dominant inheritance, only one copy of the abnormal gene is needed to cause the disorder. However, in autosomal recessive inheritance, both copies of the gene must be abnormal for the disorder to be expressed.

Choice B rationale:

Incorrect. This statement describes X-linked recessive inheritance, not autosomal recessive inheritance. In X-linked recessive inheritance, the abnormal gene is located on the X chromosome. Males have only one X chromosome, so if they inherit the abnormal gene, they will have the disorder. Females have two X chromosomes, so they must inherit two copies of the abnormal gene (one from each parent) to have the disorder.

Choice C rationale:

Correct. This statement accurately describes autosomal recessive inheritance. In autosomal recessive inheritance, both copies of the gene must be abnormal for the disorder to be expressed. This means that both parents must be carriers of the abnormal gene in order for their child to have the disorder.

Choice D rationale:

Incorrect. This statement is partially correct, but it does not fully describe autosomal recessive inheritance. The disorder can occur in both males and females, but it is not limited to heterozygous females. Homozygous females (those who have two copies of the abnormal gene) will also have the disorder.

Correct Answer is A

Explanation

Choice A rationale:

Diagnosing a fetus with a genetic disorder is outside the scope of practice for nurses. This task requires specialized training and expertise in genetics and diagnostic procedures, typically held by physicians such as geneticists, maternal-fetal medicine specialists, or genetic counselors.

Nurses play a crucial role in genetic counseling, but their responsibilities focus on:

Educating patients about genetic risks and testing options.

Obtaining informed consent for genetic testing.

Coordinating genetic testing appointments and procedures.

Providing emotional support and counseling to patients and families.

Facilitating communication between patients, families, and other healthcare providers.

Advocating for patients' rights and needs.

Choice B rationale:

Providing emotional support is a core component of nursing care, including genetic counseling. Nurses are trained to provide empathetic and compassionate support to patients and families who are facing the challenges of genetic conditions. This includes:

Active listening and validation of feelings.

Assisting with coping mechanisms and stress management.

Connecting patients with support groups and resources.

Promoting resilience and hope.

Choice C rationale:

Identifying at-risk families is a vital role for nurses in genetic counseling. By recognizing families with a history of genetic disorders or those who exhibit risk factors, nurses can initiate early intervention and preventive measures. This includes:

Taking a thorough family history.

Assessing risk factors and potential genetic concerns.

Educating families about their potential risks.

Referring families for genetic counseling and testing as appropriate.

Choice D rationale:

Collaboration with other healthcare providers and referral for specialized care are essential aspects of genetic counseling. Nurses often work within interdisciplinary teams to provide comprehensive care for patients with genetic concerns. This includes:

Communicating with geneticists, genetic counselors, and other specialists.

Coordinating referrals for genetic testing, counseling, and treatment.

Ensuring continuity of care across different healthcare settings.

A. Hispanic B. Chinese C. Caucasian/European D. African-American

Correct Answer is A

Explanation

Choice A rationale:

Hispanic women: While Hispanic cultures often emphasize strength and resilience, their expression of pain during labor can vary significantly. Some may vocalize their pain while others may remain more stoic. It's important to avoid generalizations and assess each individual's preferences and needs.

Choice B rationale:

Chinese women: In traditional Chinese culture, stoicism in the face of pain is often valued. This may be rooted in Confucianism, which emphasizes self-control and endurance. Women may be less likely to express their pain during labor to avoid appearing weak or losing face. They may also believe that vocalizing pain could negatively impact the birthing process. However, as labor progresses, they may become more vocal and request pain relief.

Choice C rationale:

Caucasian/European women: Caucasian women exhibit diverse responses to labor pain, influenced by personal experiences, cultural beliefs, and social expectations. Some may express their pain openly, while others may prefer to manage it quietly. It's crucial to avoid stereotyping and provide individualized care.

Choice D rationale:

African-American women: African-American women often express their pain during labor more openly than some other cultural groups. This may be due to historical experiences of racism and discrimination in healthcare, leading to a distrust of medical professionals and a greater reliance on self-advocacy. They may also have a stronger sense of community and support networks that encourage open expression of pain.
