Nursing Elites

1. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.

2. A newborn with an anorectal anomaly had an anoplasty performed. At the 2-week follow-up visit, a series of anal dilations are begun. What should the nurse recommend to the parents to help prevent the infant from becoming constipated?

• A. Use a soy formula.
• B. Breastfeed if possible.
• C. Administer a suppository nightly.
• D. Offer glucose water between feedings.

Correct answer: B

Rationale: Breastfeeding is the best recommendation to help prevent constipation in infants. Breast milk is easily digestible and contains the right balance of nutrients, which can lead to softer stools, thus reducing the likelihood of constipation. Offering a soy formula (Choice A) may not necessarily prevent constipation as effectively as breast milk due to differences in nutrient composition. Administering a suppository nightly (Choice C) is not a routine measure for preventing constipation in infants and may not be suitable for regular use in this scenario. Offering glucose water (Choice D) between feedings is not recommended as it does not provide the necessary nutrients found in breast milk, which are essential for preventing constipation and promoting overall health in newborns.

3. A nurse on the pediatric unit is observing the developmental skills of several 2-year-old children in the playroom. Which child should the nurse continue to evaluate?

• A. Cannot stand on one foot
• B. Builds a tower of 7 blocks
• C. Uses echolalia when speaking
• D. Colors outside the lines of a picture

Correct answer: C

Rationale: The correct answer is C because using echolalia (repeating words or phrases) is not typical for a 2-year-old and may indicate the need for further evaluation. Choices A, B, and D are within the expected developmental skills for a 2-year-old. While a 2-year-old may not be able to stand on one foot for an extended period, it is not a concerning developmental milestone at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both age-appropriate activities that demonstrate fine motor skills and creativity, respectively. However, echolalia at this age could be a sign of an underlying communication or developmental issue that warrants further assessment and monitoring.

4. The nurse is assessing a family to determine if they have access to adequate health care. Which statement accurately describes how certain families are affected by common barriers to health care?

• A. After a decade of escalation, the percentage of children living in low-income families has been on the decline since 2000.
• B. White, non-Hispanic children overall are more likely than African American and Hispanic children to be in very good or excellent health.
• C. The proportion of children between the ages of 6 and 18 who are overweight is decreasing, but a large increase is occurring in African American females.
• D. The overall health care plan of working families may improve access to specialty care but limit access to preventive services.

Correct answer: B

Rationale: Choice B is the correct answer because it accurately states that White, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This reflects a disparity in health outcomes among different racial groups. Choices A, C, and D are incorrect. Choice A is unrelated to the impact of common barriers to health care on families. Choice C talks about overweight children but does not address access to health care. Choice D discusses the impact of the overall health care plan on working families but does not specifically address the disparity in health status among different racial groups.

5. A 4-year-old child is admitted to the hospital with a diagnosis of epiglottitis. What is the priority nursing intervention?

• A. Administer antibiotics
• B. Provide humidified oxygen
• C. Keep the child NPO
• D. Position the child upright

Correct answer: C

Rationale: The priority nursing intervention for a 4-year-old child admitted with epiglottitis is to keep the child NPO (nothing by mouth). This is crucial to prevent further airway compromise due to the inflamed epiglottis. Administering antibiotics may be necessary but is not the priority at this moment. Providing humidified oxygen can support oxygenation but does not address the immediate risk of airway obstruction. Positioning the child upright may help with breathing but does not address the risk of aspiration. Keeping the child NPO is essential to maintain a patent airway and prevent complications associated with epiglottitis.
