1. Which of the following statements is true about Tay-Sachs disease?
- A. It is most commonly found among children in Jewish families of Eastern European background.
- B. Children who have this disease suffer from excessive production of mucus in the lungs and pancreas.
- C. It is most commonly found among children in Asian American families.
- D. Children who have this disease suffer from muscular dystrophy characterized by a weakening of the muscles.
Correct answer: A
Rationale: The correct answer is A. Tay-Sachs disease is most commonly found among Jewish families of Eastern European descent. It is a fatal genetic disorder that affects the nervous system. Choice B is incorrect because Tay-Sachs disease does not involve excessive mucus production in the lungs and pancreas. Choice C is incorrect as it states that Tay-Sachs disease is most commonly found among Asian American families, which is inaccurate. Choice D is also incorrect because Tay-Sachs disease does not cause muscular dystrophy characterized by weakening of the muscles.
2. _________ are problems that stem from the interaction of heredity and environmental factors.
- A. Multifactorial problems
- B. Cognitive problems
- C. Horizon problems
- D. Coronal problems
Correct answer: A
Rationale: Multifactorial problems are conditions that result from the interplay of genetic and environmental factors. These conditions, such as diabetes or heart disease, are not solely determined by genetics or environment but are influenced by a combination of both factors. Choice B, cognitive problems, refers to difficulties related to thinking, learning, and memory and are not specifically linked to genetic and environmental interactions. Choices C and D, horizon problems and coronal problems, are nonsensical terms and do not relate to the interaction of heredity and environmental factors.
3. Chromosomes are _____ structures found in cells.
- A. rod-shaped
- B. circular
- C. cone-shaped
- D. octagonal
Correct answer: A
Rationale: Chromosomes are rod-shaped structures that carry genetic information in the form of DNA. They are typically seen as elongated structures when visualized under a microscope. Choice B, circular, is incorrect as chromosomes do not have a circular shape; they are linear. Choice C, cone-shaped, is not accurate as chromosomes do not resemble cones in any way. Choice D, octagonal, is also incorrect as chromosomes do not have an octagonal appearance. Therefore, the correct answer is A, rod-shaped, which accurately describes the shape of chromosomes.
4. A healthcare provider is teaching a prenatal class about immunizations that newborns receive following birth. Which of the following immunizations should the provider include in the teaching?
- A. Hepatitis B
- B. Rotavirus
- C. Pneumococcal
- D. Varicella
Correct answer: A
Rationale: The correct answer is Hepatitis B. Newborns receive the Hepatitis B vaccine shortly after birth to provide protection against the virus. Rotavirus, Pneumococcal, and Varicella vaccines are typically administered at later stages of infancy or childhood, not immediately after birth. Rotavirus vaccine helps prevent severe diarrhea, Pneumococcal vaccine protects against infections like pneumonia and meningitis, and Varicella vaccine prevents chickenpox. However, these vaccines are not part of the routine immunizations given to newborns immediately after birth.
5. At 31 weeks gestation, a client with a fundal height measurement of 25 cm is scheduled for a series of ultrasounds to be performed every two weeks. Which explanation should the nurse provide?
- A. Assessment for congenital anomalies
- B. Recalculation of gestational age
- C. Evaluation of fetal growth
- D. Determination of fetal presentation
Correct answer: C
Rationale: The correct answer is C: 'Evaluation of fetal growth.' A fundal height measurement smaller than expected may indicate intrauterine growth restriction (IUGR), requiring serial ultrasounds to monitor fetal growth. Assessing for congenital anomalies (choice A) is usually done through detailed anatomy scans earlier in pregnancy. Recalculating gestational age (choice B) is typically unnecessary at this stage unless there are concerns about accuracy. Determining fetal presentation (choice D) is usually done closer to term to plan for the mode of delivery.
