1. What causes Down's syndrome?
- A. Alcohol abuse by the mother at the time of conception.
- B. Sex-linked chromosomal abnormalities.
- C. An extra chromosome on the 21st pair.
- D. Drug abuse by the mother during pregnancy.
Correct answer: C
Rationale: Down's syndrome, also known as trisomy 21, is caused by the presence of an extra chromosome on the 21st pair. Choice A is incorrect as alcohol abuse is not the cause of Down's syndrome. Choice B is incorrect because Down's syndrome is not related to sex-linked chromosomal abnormalities. Choice D is also incorrect as drug abuse by the mother during pregnancy is not the cause of Down's syndrome.
2. What is the primary rationale for thoroughly drying the infant immediately after birth?
- A. Stimulates crying and lung expansion.
- B. Removes maternal blood from the skin surface.
- C. Reduces heat loss from evaporation.
- D. Increases blood supply to the hands and feet.
Correct answer: C
Rationale: The primary rationale for thoroughly drying the infant immediately after birth is to reduce heat loss from evaporation. This helps maintain the infant's body temperature and prevent hypothermia. Choice A (Stimulates crying and lung expansion) is incorrect because drying the infant is not primarily done to stimulate crying but rather to prevent heat loss. Choice B (Removes maternal blood from the skin surface) is incorrect as the main reason is to prevent heat loss, not to remove maternal blood. Choice D (Increases blood supply to the hands and feet) is also incorrect as drying the infant is not intended to increase blood supply but rather to regulate body temperature.
3. Thalidomide was marketed in the 1960s as a treatment for:
- A. insomnia and nausea.
- B. infertility and impotence.
- C. Down syndrome.
- D. Turner syndrome.
Correct answer: A
Rationale: Thalidomide was initially marketed as a treatment for insomnia and nausea, particularly in pregnant women. However, it was later found to cause severe birth defects, leading to significant consequences. Choice B, infertility and impotence, is incorrect as thalidomide was not marketed for these conditions. Choices C and D, Down syndrome and Turner syndrome, are genetic conditions and not conditions for which thalidomide was intended as a treatment.
4. On the first postpartum day, the nurse examines the breasts of a new mother. Which condition is the nurse most likely to find?
- A. Firm, larger, and very tender to the touch
- B. Slightly firm with an immediate let-down response
- C. Soft with no change from before delivery
- D. Filling and secreting colostrum
Correct answer: D
Rationale: On the first postpartum day, the nurse is most likely to find the breasts filling and secreting colostrum. Colostrum secretion is common as the body prepares for breastfeeding in the initial days after delivery. Choice A is incorrect as breasts are not typically very tender immediately postpartum. Choice B is incorrect as an immediate let-down response is more related to lactation rather than the first postpartum day. Choice C is incorrect as the breasts typically undergo changes, such as filling with colostrum, after delivery.
5. A newborn is 24 hours old, and a healthcare provider is caring for them. Which of the following laboratory findings should the healthcare provider report to the provider?
- A. Hgb 20 g/dL
- B. Bilirubin 2 mg/dL
- C. Platelets 200,000/mm3
- D. WBC count 32,000/mm3
Correct answer: D
Rationale: The correct answer is D: WBC count 32,000/mm3. A WBC count of 32,000/mm3 is significantly elevated in a newborn and could indicate an infection, which needs immediate attention and intervention. High white blood cell counts in newborns can be concerning as they may suggest an ongoing infection or other underlying issues that require prompt medical evaluation and treatment. Choices A, B, and C are within normal ranges for a newborn and would not typically warrant immediate reporting to the provider. Hgb levels of 20 g/dL (Choice A) are high for newborns, but this is not as concerning as a significantly elevated WBC count. Bilirubin levels of 2 mg/dL (Choice B) are within normal limits for a newborn and do not indicate immediate issues. Platelet count of 200,000/mm3 (Choice C) is also within the normal range for a newborn and would not require immediate reporting.
