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. When assessing a child with leukemia, which clinical manifestations should the nurse anticipate?

• A. Petechiae, fever, fatigue
• B. Headache, papilledema, irritability
• C. Muscle wasting, weight loss, fatigue
• D. Decreased intracranial pressure, psychosis, confusion

Correct answer: A

Rationale: The correct answer is A: Petechiae, fever, fatigue. Children with leukemia commonly present with petechiae (due to low platelet count), fever (due to infection), and fatigue (due to anemia), which are classic manifestations of the disease. Option B is incorrect because headache, papilledema, and irritability are more indicative of increased intracranial pressure, not leukemia. Option C is incorrect as muscle wasting and weight loss are not typical initial manifestations of leukemia in children. Option D is incorrect as decreased intracranial pressure, psychosis, and confusion are not commonly associated with leukemia.

3. The nurse is teaching a parent of a 6-month-old infant with gastroesophageal reflux (GER) before discharge. What instructions should the nurse include?

• A. Elevate the head of the bed in the crib to a 90-degree angle while the infant is sleeping.
• B. Hold the infant in the prone position after a feeding.
• C. Discontinue breastfeeding so that a formula and rice cereal mixture can be used.
• D. Prescribed cimetidine (Tagamet) should be given 30 minutes before feedings.

Correct answer: D

Rationale: Cimetidine is an H2 blocker that reduces stomach acid, helping manage GER. Holding the infant in the prone position is not recommended due to the risk of SIDS. Breastfeeding should not be discontinued unless advised by a physician. Elevating the head to 90 degrees is excessive.

4. Which is the leading cause of death in infants younger than 1 year in the United States?

• A. Congenital anomalies
• B. Sudden infant death syndrome
• C. Disorders related to short gestation and low birth weight
• D. Maternal complications specific to the perinatal period

Correct answer: A

Rationale: Congenital anomalies are the leading cause of death in infants younger than 1 year in the United States.

5. What is the priority assessment for a nurse when caring for an infant suspected of having necrotizing enterocolitis (NEC)?

• A. Hold feedings.
• B. Check gastric residuals before feedings.
• C. Take rectal temperature.
• D. Closely monitor abdominal distention.

Correct answer: D

Rationale: The correct answer is D: Closely monitor abdominal distention. Monitoring the abdomen for signs of distention is crucial in the early detection of necrotizing enterocolitis (NEC). In NEC, the bowel wall is edematous and breaking down, leading to abdominal distention. Holding feedings is important in the management of NEC, as feedings may need to be stopped temporarily. Checking gastric residuals before feedings helps in assessing the infant's tolerance to feedings. Taking rectal temperatures is contraindicated in NEC as it can lead to the perforation of the bowel.
