Question 1
Regular
What factor describes the etiology of this genetic change?
Correct!
Incorrect
The correct answer is: B
Rationale
The patient has a nondisjunction occurring during meiosis. This genetic change is primarily attributed to nondisjunction, where chromosomes fail to separate properly, leading to an abnormal number of chromosomes in the gametes, which can result in conditions such as Down syndrome.
A: The mother also has genetic mutation of chromosome 21. While maternal genetic mutations can contribute to certain conditions, this option does not specifically address the mechanism of nondisjunction affecting the patient.
C: During meiosis, a reduction of chromosomes resulted in 23. This describes a normal meiotic process; however, it fails to highlight the critical issue of nondisjunction that leads to genetic abnormalities.
D: The patient will have a single X chromosome and infertility. This statement relates to Turner syndrome but does not pertain to the specific genetic change caused by nondisjunction during meiosis.

Question 3
Regular
Based on the nurses knowledge of neurofibromatosis, the nurse understands that a single family member has which of the following?
Correct!
Incorrect
The correct answer is: A
Rationale
A spontaneous mutation. A single family member with neurofibromatosis likely exhibits a spontaneous mutation, which arises randomly and is not inherited from parents. This condition often occurs due to new mutations in the NF1 gene.
B: A germline mutation. Germline mutations are inherited from parents and affect the entire genome, which does not apply here as the question refers to an individual family member.
C: A nondisjunction. Nondisjunction involves the failure of chromosome separation during meiosis, leading to conditions like Down syndrome, not applicable in the context of neurofibromatosis.
D: A monosomy. Monosomy refers to the absence of one chromosome in a pair, which is unrelated to neurofibromatosis and does not explain the condition in a family member.

Question 4
Regular
What will the nurse understand about the childrens possibility of inheriting the gene for the disease?
Correct!
Incorrect
The correct answer is: B
Rationale
Each child will have a 50% chance of inheriting the disease. This probability arises from the genetic pattern typically observed in autosomal dominant conditions, where one affected parent can pass on the gene to half of their offspring.
A: Each child will have a 25% chance of inheriting the disease. This percentage applies to scenarios involving two carrier parents, not applicable here with one affected parent.
C: Each child will have a 75% chance of inheriting the disease. This figure misinterprets inheritance patterns, as it suggests multiple affected genes or alleles, which isn’t relevant in this case.
D: Each child will have no chance of inheriting the disease. This scenario disregards the possibility of gene transmission from an affected parent, which clearly allows for inheritance.

What should the nurse practitioner tell them about cystic fibrosis?
Correct!
Incorrect
The correct answer is: D
Rationale
Cystic fibrosis is an autosomal recessive disorder. This means that a child must inherit two copies of the mutated gene, one from each parent, to develop the condition, highlighting its genetic transmission pattern.
A: It is an autosomal dominant disorder. Cystic fibrosis does not follow dominant inheritance, where a single mutated allele could cause the disease; it requires two recessive alleles instead.
B: It is passed by mitochondrial inheritance. Mitochondrial inheritance involves genes in mitochondrial DNA, which is unrelated to cystic fibrosis, as it stems from mutations in the CFTR gene on an autosome.
C: It is an X-linked inherited disorder. Cystic fibrosis is not linked to the X chromosome; it is caused by mutations on chromosome 7, illustrating that it does not involve X-linked inheritance.
