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.

What foods are appropriate for a 30-month-old toddler on a regular diet?
- A. Hamburger with bun and grapes
- B. Chicken fingers and french fries
- C. Hot dog with bun and potato chips
- D. Macaroni and cheese and Cheerios
Correct Answer: D
Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet. These foods are easy to chew, digest, and are generally well-liked by toddlers. Option A, a hamburger with bun and grapes, may be difficult for a toddler to handle due to the size of the hamburger and grapes pose a choking hazard. Option B, chicken fingers and french fries, may be too greasy and processed for a toddler's developing digestive system. Option C, hot dog with bun and potato chips, is also not ideal as hot dogs can be a choking hazard and potato chips are high in salt and may not provide adequate nutrition.
When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
- A. nondisjunction.
- B. X-linked recessive inheritance.
- C. genomic imprinting.
- D. autosomal dominant inheritance.
Correct Answer: A
Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.
What behavior does the nurse anticipate while feeding a newborn with choanal atresia?
- A. Chokes on the feeding
- B. Has difficulty swallowing
- C. Does not appear to be hungry
- D. Takes about half of the feeding
Correct Answer: D
Rationale: Correct answer: When feeding a newborn with choanal atresia, the nurse should anticipate that the infant may take only part of the feeding. This behavior is due to the condition causing difficulty in breathing through the nose while feeding, prompting the infant to pause for air. Choice A, 'Chokes on the feeding,' is incorrect as it does not specifically relate to the feeding behavior expected in choanal atresia. Choice B, 'Has difficulty swallowing,' is also incorrect because the issue in choanal atresia is primarily related to breathing rather than swallowing. Choice C, 'Does not appear to be hungry,' is not the typical behavior seen in infants with choanal atresia; they may still display hunger cues but struggle with feeding due to the condition.
A child with sickle cell anemia develops severe chest pain, fever, a cough, and dyspnea. The nurse's first action is to
- A. administer 100% oxygen to relieve hypoxia
- B. administer pain medication to relieve symptoms
- C. notify the practitioner because chest syndrome is suspected
- D. notify the practitioner because the child may be having a stroke
Correct Answer: C
Rationale: In a child with sickle cell anemia experiencing severe chest pain, fever, cough, and dyspnea, the priority action is to suspect acute chest syndrome, a life-threatening complication. The nurse's first action should be to notify the practitioner for immediate evaluation and intervention. Administering 100% oxygen (Choice A) may be necessary later but is not the initial priority. Administering pain medication (Choice B) should not precede notifying the practitioner, as addressing the underlying cause is crucial. The symptoms described are more indicative of acute chest syndrome than a stroke, so notifying the practitioner for chest syndrome (Choice C) takes precedence over suspecting a stroke (Choice D).
