Question 1 of 5
Is Duchenne muscular dystrophy a sex-linked abnormality?
Correct Answer: A
Rationale: The correct answer is A: TRUE. Duchenne muscular dystrophy is an X-linked recessive disorder, primarily affecting males. This is due to the inheritance of the mutated gene on the X chromosome. Choices B, C, and D are incorrect because Duchenne muscular dystrophy is specifically classified as a sex-linked disorder affecting males due to the inheritance pattern.
Question 2 of 5
When do mothers usually feel the first fetal movements during pregnancy?
Correct Answer: A
Rationale: Mothers usually feel the first fetal movements, known as 'quickening,' around the 18th to 20th week of pregnancy. Feeling fetal movements during the first month is unlikely and uncommon. Therefore, option B is incorrect. Options C and D are also incorrect as mothers typically do feel fetal movements during pregnancy, just not during the first month.
Question 3 of 5
A nurse on an antepartum unit is reviewing the medical records for four clients. Which of the following clients should the nurse assess first?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A client is receiving oxytocin by continuous IV infusion for labor induction. Which of the following interventions should the nurse include in the plan?
Correct Answer: A
Rationale: The correct answer is to increase the infusion rate every 30 to 60 minutes. This approach allows for the careful monitoring and adjustment of oxytocin administration during labor induction. Choice B is incorrect because maintaining the client in a supine position can decrease blood flow to the placenta and compromise fetal oxygenation. Choice C is incorrect as titrating the infusion rate by 4 milliunits/min is not a standard practice for oxytocin administration. Choice D is incorrect as limiting IV intake to 4 L per 24 hours is not specifically related to the administration of oxytocin for labor induction.
Question 5 of 5
Polygenic traits are those that are:
Correct Answer: D
Rationale: Polygenic traits, such as height and skin color, are determined by several pairs of genes working together. These traits are influenced by the combined effects of multiple genes across the genome, rather than being controlled by a single gene pair. Choices A, B, and C are incorrect because polygenic traits are not specifically developed during adolescence, transmitted by the mother, or uncommon in humans. Understanding polygenic traits is essential in genetics as they demonstrate the complexity of genetic inheritance and the influence of multiple genes on a single trait.
