Nursing Elites

1. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome:

• A. are unlikely to die from cardiovascular problems by middle age.
• B. have no specific characteristic features.
• C. show deficits in cognitive development.
• D. are likely to have only 46 chromosomes.

Correct answer: C

Rationale: The correct answer is C. According to a study in 2013 by van Gameren-Oosterom, individuals with Down syndrome often exhibit deficits in cognitive development. This is a common characteristic of Down syndrome, along with other health challenges. Choice A is incorrect because individuals with Down syndrome are at a higher risk of cardiovascular problems, contrary to being unlikely to die from them. Choice B is incorrect as Down syndrome is associated with specific characteristic features such as distinctive facial characteristics, making the statement that they have no specific features incorrect. Choice D is incorrect as individuals with Down syndrome have an extra copy of chromosome 21, resulting in a total of 47 chromosomes, not 46.

2. A client at 30 weeks gestation reports that she has not felt the baby move in the last 24 hours. Concerned, she arrives in a panic at the obstetric clinic where she is immediately sent to the hospital. Which assessment warrants immediate intervention by the nurse?

• A. Fetal Heart rate 60 beats per minute
• B. Ruptured amniotic membrane
• C. Onset of uterine contractions
• D. Leaking amniotic fluid

Correct answer: A

Rationale: A fetal heart rate of 60 beats per minute is significantly below the normal range (110-160 bpm) and indicates fetal distress, requiring immediate intervention. This low heart rate can be a sign of fetal compromise or distress, necessitating urgent evaluation and intervention to ensure the well-being of the fetus. Choices B, C, and D do not indicate immediate fetal distress requiring urgent intervention. Ruptured amniotic membrane, onset of uterine contractions, and leaking amniotic fluid are important assessments but do not present an immediate threat to the fetus's life like a severely low fetal heart rate.

3. Which of the following illnesses causes degeneration of the central nervous system?

• A. Tay-Sachs disease
• B. Cystic fibrosis
• C. Turner syndrome
• D. Klinefelter syndrome

Correct answer: A

Rationale: Tay-Sachs disease is a genetic disorder that causes a progressive degeneration of the central nervous system, particularly in infants. Choice B, Cystic fibrosis, is a genetic disorder that primarily affects the lungs and digestive system, not the central nervous system. Choices C and D, Turner syndrome and Klinefelter syndrome, are chromosomal disorders that do not directly involve degeneration of the central nervous system.

4. A newborn's head circumference is 12 inches (30.5 cm) and his chest measurement is 13 inches (33 cm). The nurse notes that this infant has no molding, and it was a breech presentation delivered by cesarean section. What action should the nurse take based on this data?

• A. No action needs to be taken, it is normal for an infant born by cesarean section to have a small head circumference.
• B. Notify the pediatrician immediately. These signs support the possibility of hydrocephalus.
• C. Call these findings to the attention of the pediatrician. The head/chest ratio is abnormal.
• D. Record the findings on the chart. They are within normal limits.

Correct answer: D

Rationale: Head and chest circumference measurements are within normal limits for a newborn, especially for those delivered by cesarean section, so no immediate action is required beyond documentation.

5. Is color blindness a sex-linked abnormality?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. Always

Correct answer: A

Rationale: The correct answer is A: TRUE. Color blindness is indeed a sex-linked abnormality as it is often associated with genes on the X chromosome. Since males have only one X chromosome, they are more likely to inherit color blindness if the gene is present. This makes color blindness more common in males. Choice B (FALSE) is incorrect because color blindness is linked to the X chromosome. Choices C (Sometimes) and D (Always) are incorrect as color blindness is consistently tied to the X chromosome.
