Nursing Elites

1. Chemicals, agents, or factors that cause physical defects in the developing embryo and are most harmful during organogenesis are:

• A. Teratogens
• B. Heterozygous
• C. Inborn errors
• D. Multifactorial

Correct answer: A

Rationale: Teratogens are substances that can cause congenital abnormalities, especially during the first trimester when organogenesis occurs. Choice A, Teratogens, is the correct answer as it specifically refers to substances that cause physical defects in the developing embryo. Choices B, Heterozygous, C, Inborn errors, and D, Multifactorial, are incorrect as they do not directly relate to substances that cause physical defects in embryos during organogenesis.

2. The nurse is assessing a 3-day-old breastfed newborn who weighed 3400 g (7 pounds, 8 oz) at birth. The infant’s mother is now concerned because the infant weighs 3147 g (6 pounds, 15 oz). The most appropriate nursing intervention is what?

• A. Recommend supplemental feedings of formula.
• B. Explain that this weight loss is within normal limits.
• C. Assess the child further to determine the cause of excessive weight loss.
• D. Encourage the mother to express breast milk for bottle-feeding the infant.

Correct answer: B

Rationale: A neonate normally loses about 10% of the birth weight by age 3 to 4 days. The birth weight is usually regained by the 10th day of life. In this case, the weight loss from 3400 g to 3147 g is within the expected range. Therefore, the most appropriate action is to explain to the mother that this weight loss is within normal limits. Choice A is incorrect because supplemental feedings of formula are not indicated for this expected weight loss in a breastfed newborn. Choice C is incorrect as there is no evidence to suggest excessive weight loss at this point. Choice D is unnecessary at this stage and may not align with the current situation of normal weight loss post-birth.

3. Which statement best describes colic?

• A. Periods of abdominal pain resulting in weight loss
• B. Usually the result of poor or inadequate mothering
• C. Periods of abdominal pain and crying occurring in infants older than age 6 months
• D. A paroxysmal abdominal pain or cramping manifested by episodes of loud crying

Correct answer: D

Rationale: Colic is characterized by episodes of loud, inconsolable crying, often due to abdominal discomfort, and typically occurs in infants younger than 6 months. It is not related to poor mothering, nor does it necessarily result in weight loss.

4. At a well-child visit, parents ask the nurse how to know if a daycare facility is a good choice for their infant. Which observation should the nurse stress as especially important to consider when making the selection?

• A. Developmentally appropriate toys
• B. Nutritious snacks served to the children
• C. Handwashing by providers after diaper changes
• D. Certified caregivers for each of the age groups at the facility

Correct answer: C

Rationale: Ensuring that providers practice proper handwashing after diaper changes is crucial in preventing the spread of infections and maintaining a hygienic environment for the infants.

5. What is characteristic of a neonate’s vision?

• A. Pupils react to light
• B. Tear glands function
• C. Blink reflex is absent
• D. Ciliary muscles are mature

Correct answer: A

Rationale: The correct answer is A: 'Pupils react to light.' Newborns' pupils do react to light, indicating that the visual pathway is functioning. However, a neonate's vision is still developing, and they can only focus on objects close to their face. Choice B is incorrect because tear glands are functional at birth. Choice C is incorrect because the blink reflex is present in neonates and helps protect their eyes. Choice D is incorrect as neonates' ciliary muscles are not fully developed.
