Nursing Elites

1. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted by an autosomal recessive gene.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.

2. A nurse is teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration. What should the nurse emphasize?

• A. Rotate injection sites
• B. Administer insulin before meals
• C. Store insulin in the refrigerator
• D. Administer insulin at bedtime

Correct answer: A

Rationale: The correct answer is to rotate injection sites. Rotating injection sites is crucial in insulin administration to prevent lipodystrophy, which is the breakdown of subcutaneous fat at the injection site. It also helps ensure consistent insulin absorption. Administering insulin before meals (choice B) is important to match insulin peak action with the rise in blood glucose after eating. Storing insulin in the refrigerator (choice C) is correct to maintain its potency and stability. Administering insulin at bedtime (choice D) may not be suitable for all patients and is not a universal recommendation for insulin administration.

3. A nurse is caring for an infant with phenylketonuria (PKU). What diet should the nurse anticipate will be ordered by the healthcare provider?

• A. Fat-free
• B. Protein-enriched
• C. Phenylalanine-free
• D. Low-phenylalanine

Correct answer: D

Rationale: A low-phenylalanine diet is necessary for infants with PKU because it helps prevent the accumulation of phenylalanine, which can result in brain damage. Fat-free (Choice A) and protein-enriched (Choice B) diets are not specifically indicated for PKU. While phenylalanine-free (Choice C) may seem logical, complete elimination of phenylalanine is not practical or safe as it is an essential amino acid. Therefore, the correct choice is a low-phenylalanine diet, which restricts phenylalanine intake to a safe level.

4. The nurse is caring for a 3-day-old girl with Down syndrome whose mother had no prenatal care. What is the priority nursing diagnosis?

• A. Imbalanced nutrition, less than body requirements related to the effects of hypotonia
• B. Deficient knowledge related to the presence of a genetic disorder
• C. Delayed growth and development related to a cognitive impairment
• D. Impaired physical mobility related to poor muscle tone

Correct answer: A

Rationale: The priority nursing diagnosis for a 3-day-old girl with Down syndrome, whose mother had no prenatal care, is imbalanced nutrition, less than body requirements related to the effects of hypotonia. Newborns with Down syndrome often experience feeding difficulties due to hypotonia, which can lead to inadequate nutrition intake. Option B is incorrect because at this age, the infant is not capable of having knowledge deficits related to a genetic disorder. Option C is incorrect as delayed growth and development are not the immediate priority in this scenario. Option D is incorrect as impaired physical mobility is not typically a priority concern for a newborn with Down syndrome.

5. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.
