Nursing Elites

1. What is a procedure for using ultrasonic sound waves to create a picture of an embryo or fetus?

• A. Phenotype
• B. Sonogram
• C. Genotype
• D. Alpha-fetoprotein (AFP) assay

Correct answer: B

Rationale: A sonogram, also known as an ultrasound, is a procedure that utilizes sound waves to generate images of a developing embryo or fetus. This imaging technique is commonly used in prenatal care to monitor fetal development and identify any potential abnormalities. Choices A, C, and D are incorrect because a phenotype refers to an individual's observable traits resulting from genetic and environmental influences, a genotype is an individual's genetic makeup, and an alpha-fetoprotein (AFP) assay is a blood test used to screen for certain birth defects.

2. A nurse is reviewing laboratory results for a term newborn who is 24 hours old. Which of the following results require intervention by the nurse?

• A. WBC count 10,000/mm3
• B. Platelets 180,000/mm3
• C. Hemoglobin 20g/dL
• D. Glucose 20 mg/dL

Correct answer: D

Rationale: A glucose level of 20 mg/dL is critically low for a newborn and requires immediate intervention. Hypoglycemia in a newborn can lead to serious complications such as neurologic deficits. The normal range for glucose levels in a newborn is typically 40-60 mg/dL. Choices A, B, and C represent normal or acceptable values for a term newborn and do not require immediate intervention. A WBC count of 10,000/mm3, platelets of 180,000/mm3, and hemoglobin of 20g/dL are all within normal ranges for a term newborn and do not raise immediate concerns.

3. What is the typical sex chromosome pattern for males?

• A. XX
• B. XYY
• C. XY
• D. XXY

Correct answer: C

Rationale: The correct answer is C: XY. In males, the typical sex chromosome pattern consists of one X chromosome and one Y chromosome. Choice A (XX) is the sex chromosome pattern for females. Choice B (XYY) is a chromosomal disorder where males have an extra Y chromosome. Choice D (XXY) is the sex chromosome pattern associated with Klinefelter syndrome, a condition where males have an extra X chromosome.

4. A newborn is being assessed following a forceps-assisted birth. Which of the following clinical manifestations should the nurse identify as a complication of the birth method?

• A. Hypoglycemia
• B. Polycythemia
• C. Facial Palsy
• D. Bronchopulmonary dysplasia

Correct answer: C

Rationale: Facial palsy is a known complication of forceps-assisted birth. During forceps delivery, pressure applied to the facial nerve can result in facial palsy. The newborn may present with weakness or paralysis of the facial muscles on one side. Hypoglycemia (Choice A) is not directly related to forceps-assisted birth. Polycythemia (Choice B) is a condition characterized by an increased number of red blood cells and is not typically associated with forceps delivery. Bronchopulmonary dysplasia (Choice D) is a lung condition that primarily affects premature infants who require mechanical ventilation and prolonged oxygen therapy, not a direct outcome of forceps-assisted birth.

5. When children who are reared by adoptive parents are nonetheless more similar to their natural parents in a trait, it can be concluded that:

• A. the genetic characteristics of the children change over time.
• B. heredity is solely responsible for how a child grows.
• C. the environment is solely responsible for the development of those characteristics.
• D. genetics play a role in the development of those characteristics.

Correct answer: D

Rationale: When children exhibit traits that are more similar to their biological parents than their adoptive parents, it indicates a strong genetic influence on those traits. This similarity suggests that genetics play a significant role in the development of the observed characteristics. Choice A is incorrect because genetic characteristics do not change over time in this context. Choice B is incorrect as it implies that heredity is the only factor, disregarding the impact of the environment. Choice C is also incorrect as it suggests that only the environment influences trait development, overlooking the genetic contribution.
