Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. A nurse is teaching the parents of a child with a diagnosis of epilepsy about seizure precautions. What should the nurse include in the teaching?

• A. Keep a diary of seizure activity
• B. Administer antiepileptic medication only when a seizure occurs
• C. Restrict the child's activities to prevent seizures
• D. Teach seizure first aid to family members

Correct answer: D

Rationale: Teaching seizure first aid to family members is crucial for ensuring the child's safety during a seizure. Keeping a diary of seizure activity (choice A) is important for tracking patterns and triggers but does not directly relate to immediate safety during a seizure. Administering antiepileptic medication only when a seizure occurs (choice B) is incorrect as medications should be given as prescribed to maintain therapeutic levels. Restricting the child's activities to prevent seizures (choice C) is not an appropriate approach as it may limit the child's quality of life without guaranteeing seizure prevention.

3. What is the priority nursing responsibility when a 3-year-old child in a crib is experiencing a tonic-clonic seizure with a clamped jaw?

• A. Apply restraints.
• B. Administer oxygen.
• C. Protect the child from self-injury.
• D. Insert a plastic airway in the child’s mouth.

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints (Choice A) can cause harm by restricting movement during the seizure. While administering oxygen (Choice B) may be necessary, it is not the immediate priority during an active seizure. Inserting a plastic airway (Choice D) is contraindicated as it can lead to injury and is not recommended during a seizure. Protecting the child from self-injury (Choice C) is crucial to prevent harm from uncontrolled movements and potential falls, ensuring the safety of the child.

4. A group of nursing students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The correct answer is 'Hormonal secretion' (Choice B). The primary function of the endocrine system is to secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction. Choice A, 'Regulation of water balance,' is primarily controlled by the kidneys and the urinary system, not the endocrine system. Choice C, 'Cellular metabolism,' is more directly related to the functions of individual cells rather than the overall function of the endocrine system. Choice D, 'Growth stimulation,' is a function that can be influenced by hormones secreted by the endocrine system, but it is not the primary function of the system.

5. What explanation should the nurse give a parent about the purpose of a tetanus toxoid injection for their child?

• A. Passive immunity is conferred temporarily.
• B. Long-lasting active immunity is conferred.
• C. Lifelong active natural immunity is conferred.
• D. Passive natural immunity is conferred temporarily.

Correct answer: B

Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.
