1. A 1-month-old girl with low-set ears and severe hypotonia has been diagnosed with trisomy 18. Which nursing diagnosis would the nurse identify as most likely?
- A. Interrupted family process related to the child's diagnosis
- B. Deficient knowledge related to the genetic disorder
- C. Grieving related to the child's poor prognosis
- D. Ineffective coping related to the stress of providing care
Correct answer: C
Rationale: The most likely nursing diagnosis for a 1-month-old girl with trisomy 18, characterized by low-set ears and severe hypotonia, is 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience grief as they come to terms with the challenges and uncertainties associated with the condition. 'Interrupted family process' may not be as relevant since the primary focus is on the child's condition. 'Deficient knowledge related to the genetic disorder' could be important but may not be the most likely initial concern, as emotional support for the family is crucial at this point. 'Ineffective coping related to the stress of providing care' is a broad diagnosis that does not specifically address the emotional response to the child's prognosis, which is the primary concern in this case.
2. A healthcare provider is assessing a child with suspected bacterial meningitis. What is a common clinical manifestation that the provider is likely to observe?
- A. Rash
- B. Photophobia
- C. Jaundice
- D. Kernig sign
Correct answer: D
Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.
3. The parents of a 6-week-old infant who was born without an immune system ask a nurse why their baby is still so healthy. How should the nurse reply?
- A. Exposure to pathogens during this time can be limited.
- B. Some antibodies are produced by the infant’s colonic bacteria.
- C. Antibodies are passively received from the mother through the placenta and breast milk.
- D. Fewer antibodies are produced by the fetal thymus during the eighth and ninth months of gestation.
Correct answer: C
Rationale: The correct answer is C. Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially. Choice A is incorrect because a 6-week-old infant born without an immune system would not be able to limit exposure to pathogens effectively. Choice B is incorrect as antibodies produced by colonic bacteria are not a significant source of immunity in infants. Choice D is incorrect as the fetal thymus primarily plays a role in T cell development rather than antibody production during gestation.
4. 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.
5. After surgery to correct hypertrophic pyloric stenosis (HPS) in a 3-week-old infant who had been formula-fed, which postoperative feeding order is appropriate?
- A. Thickened formula 24 hours after surgery
- B. Withholding feedings for the first 24 hours
- C. Regular formula feeding within 24 hours after surgery
- D. Additional glucose feedings as desired after the first 24 hours
Correct answer: C
Rationale: After surgery for hypertrophic pyloric stenosis (HPS), it is appropriate to resume regular formula feeding within 24 hours postoperatively to promote recovery. Choice A, thickened formula after surgery, may be too heavy for the infant's digestive system at this early stage. Withholding feedings for the first 24 hours (Choice B) is not recommended as early feeding helps with recovery. Additional glucose feedings (Choice D) are not necessary and may not provide the balanced nutrition required after surgery.
