A primigravida at 36 weeks gestation who is RH-negative experienced abdominal trauma in a motor vehicle collision. Which assessment finding is most important for the nurse to report to the healthcare provider?

  • A. Fetal heart rate at 162 beats per minute
  • B. Mild contractions every 10 minutes
  • C. Trace of protein in the urine
  • D. Positive fetal hemoglobin testing
Correct Answer: D

Rationale: The correct answer is 'Positive fetal hemoglobin testing' (D). Positive fetal hemoglobin testing (Kleihauer-Betke test) indicates fetal-maternal hemorrhage, which is critical in an RH-negative mother due to the risk of isoimmunization. This condition can lead to sensitization of the mother's immune system against fetal blood cells, potentially causing hemolytic disease of the newborn in subsequent pregnancies. Reporting this finding promptly is crucial for appropriate management and interventions. Choices A, B, and C are not as critical in this scenario. While monitoring fetal heart rate and contractions is important, the detection of fetal-maternal hemorrhage takes precedence due to the serious implications it poses for the current and future pregnancies of an RH-negative mother.

Monozygotic (MZ) twins are known as fraternal twins.

  • A. TRUE
  • B. FALSE
  • C. Possibly
  • D. Never
Correct Answer: B

Rationale: The correct answer is B: 'FALSE.' Monozygotic (MZ) twins are identical twins, not fraternal. Fraternal twins are dizygotic (DZ). The statement in the question is incorrect as MZ twins are genetically identical, while fraternal twins actually refer to dizygotic twins who develop from two separate fertilized eggs. Therefore, monozygotic twins are not known as fraternal twins, making option B the correct choice. Options A, C, and D are incorrect as they do not accurately describe the relationship between monozygotic and fraternal twins.

Rico is a man who has enlarged breasts and suffers from mild mental retardation. He has a problem learning languages, and his body produces less of the male sex hormone testosterone than normal males. Rico is most likely suffering from:

  • A. Klinefelter syndrome.
  • B. Tay-Sachs disease.
  • C. Turner syndrome.
  • D. Down syndrome.
Correct Answer: A

Rationale: Rico's symptoms align with Klinefelter syndrome, which is characterized by an extra X chromosome in males (XXY). Enlarged breasts (gynecomastia), mild mental retardation, learning difficulties, and reduced testosterone production are common features of Klinefelter syndrome. Choice B, Tay-Sachs disease, is a genetic disorder that affects the nervous system and is not associated with the symptoms described. Choice C, Turner syndrome, occurs in females with a missing or partially missing X chromosome and does not fit Rico's profile. Choice D, Down syndrome, is caused by an extra copy of chromosome 21 and typically does not present with the symptoms mentioned for Rico.

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.

During the client's initial prenatal visit, which of the following would indicate a need for further assessment?

  • A. History of diabetes for 6 years.
  • B. Exercises three times a week.
  • C. Occasional use of over-the-counter pain relievers.
  • D. Maternal age 30 years.
Correct Answer: A

Rationale: A history of diabetes for 6 years indicates a pre-existing medical condition that can significantly impact both the mother and the developing fetus during pregnancy. This necessitates further assessment and monitoring to manage potential complications. Regular exercise (Choice B) is generally beneficial during pregnancy and does not raise immediate concerns. Occasional use of over-the-counter pain relievers (Choice C) is common and does not necessarily indicate a need for further assessment during the initial visit. Maternal age of 30 years (Choice D) falls within the normal range for childbearing and is not a standalone factor requiring immediate further assessment.

Which field of biology studies heredity?

  • A. Etiology.
  • B. Ecology.
  • C. Genetics.
  • D. Eugenics.
Correct Answer: C

Rationale: Genetics is the branch of biology that focuses on the study of heredity and variation in organisms. Etiology (choice A) deals with the causes of diseases, not heredity. Ecology (choice B) is concerned with the relationships between organisms and their environment, not specifically heredity. Eugenics (choice D) is a controversial field that involves improving the genetic quality of the human population through selective breeding, which is different from the study of heredity itself.
