Nursing Elites

1. According to a study in the year 2013 by Fellman, if a woman is a twin, if her mother was a twin, or if she has previously borne twins, then:

• A. she will bear only monozygotic (MZ) twins.
• B. the chances of her becoming pregnant decrease.
• C. she is likely to be a healthy mother.
• D. the chances rise that she will bear twins.

Correct answer: D

Rationale: According to the study, the chances of a woman bearing twins increase if she is a twin herself, if her mother was a twin, or if she has previously borne twins. Therefore, the correct answer is D. Choice A is incorrect because the study does not specify that she will bear only monozygotic twins. Choice B is incorrect as the study does not mention any decrease in the chances of becoming pregnant. Choice C is incorrect because the study does not provide information about the woman's health status, focusing instead on the likelihood of bearing twins.

2. A new mother who is a lacto-ovo vegetarian plans to breastfeed her infant. Which information should the nurse provide prior to discharge?

• A. Continue prenatal vitamins with B12 while breastfeeding
• B. Avoid using Lanolin-based nipple cream or ointment
• C. Offer iron-fortified supplemental formula daily
• D. Weigh the baby weekly to evaluate the newborn's growth

Correct answer: A

Rationale: The correct answer is A: 'Continue prenatal vitamins with B12 while breastfeeding.' Vitamin B12 is crucial for lacto-ovo vegetarian mothers to prevent deficiencies in both the mother and the infant. Choice B is incorrect as Lanolin-based nipple cream is safe for use during breastfeeding. Choice C is not necessary unless there are specific indications for iron supplementation. Choice D, weighing the baby weekly, is important for monitoring growth but not specifically related to the mother's diet.

3. Which of the following statements is a symptom of cystic fibrosis in children?

• A. Cystic fibrosis leads to uncontrollable muscle movements and personality changes.
• B. Cystic fibrosis leads to the excessive production of thick mucus that clogs the pancreas and lungs.
• C. Cystic fibrosis causes red blood cells to clump together, obstructing small blood vessels and decreasing the oxygen supply.
• D. Cystic fibrosis causes the central nervous system to degenerate, resulting in death.

Correct answer: B

Rationale: The correct answer is B. Cystic fibrosis is a genetic disorder that causes the body to produce thick, sticky mucus. This mucus can clog the airways in the lungs and obstruct the pancreas, leading to severe respiratory and digestive problems. Choice A is incorrect because uncontrollable muscle movements and personality changes are not typical symptoms of cystic fibrosis. Choice C is incorrect because cystic fibrosis does not directly cause red blood cells to clump together and obstruct small blood vessels. Choice D is incorrect because cystic fibrosis primarily affects the respiratory and digestive systems, not the central nervous system.

4. 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.

5. A healthcare provider is assessing a newborn immediately following a vaginal birth. For which of the following findings should the provider intervene?

• A. Molding
• B. Vernix Caseosa
• C. Acrocyanosis
• D. Sternal retractions

Correct answer: D

Rationale: Sternal retractions in a newborn indicate respiratory distress and require immediate intervention. This finding suggests the newborn is having difficulty breathing and needs prompt attention to ensure adequate oxygenation. Molding, the overlapping of fetal skull bones during birth, is a normal and expected process that does not require intervention. Vernix Caseosa, the protective white substance on the skin, and Acrocyanosis, the bluish discoloration of extremities, are both common and benign findings in newborns that do not necessitate immediate action. Therefore, the healthcare provider should focus on addressing sternal retractions to manage the respiratory distress effectively.
