Nursing Elites

1. A healthcare provider is assessing a 3-month-old infant with suspected pyloric stenosis. What clinical manifestation is the healthcare provider likely to observe?

• A. Projectile vomiting
• B. Diarrhea
• C. Constipation
• D. Abdominal distension

Correct answer: A

Rationale: Projectile vomiting is a classic clinical manifestation of pyloric stenosis in infants. This occurs due to the narrowing of the pyloric sphincter, leading to the forceful expulsion of gastric contents in a projectile manner. Diarrhea (choice B) is not typically associated with pyloric stenosis. Constipation (choice C) is also not a common symptom of this condition. Abdominal distension (choice D) may occur in pyloric stenosis but is not as specific or characteristic as projectile vomiting in diagnosing this condition.

2. A 3-year-old child is being discharged after being treated for dehydration. What should the nurse include in the discharge teaching?

• A. Monitor for signs of infection
• B. Monitor for signs of dehydration
• C. Monitor for signs of hypovolemia
• D. Monitor for signs of malnutrition

Correct answer: B

Rationale: Correct! When a child is being discharged after treatment for dehydration, it is important to educate caregivers about monitoring for signs of dehydration to prevent reoccurrence. Dehydration is the primary concern in this scenario, as the child's fluid levels need to be closely monitored. Choices A, C, and D are incorrect because while infection, hypovolemia, and malnutrition are also important considerations in pediatric care, the immediate focus after treating dehydration should be on preventing its recurrence by monitoring for signs of dehydration.

3. Which of the following techniques represents the most appropriate method of opening the airway of an infant with no suspected neck injury?

• A. lift up the chin and hyperextend the neck
• B. tilt the head back without hyperextending the neck
• C. gently lift the chin while maintaining slight flexion of the neck
• D. perform the technique as you would for an older child or adult

Correct answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.

4. What is a common finding that the nurse can identify in most children with symptomatic cardiac malformations?

• A. Mental retardation
• B. Inherited genetic factors
• C. Delayed physical growth
• D. Clubbing of the fingertips

Correct answer: C

Rationale: Delayed physical growth is a common finding in children with symptomatic cardiac malformations. This occurs due to insufficient oxygenation and nutrient supply, which can affect overall growth and development. Mental retardation (Choice A) is not typically associated with symptomatic cardiac malformations. Inherited genetic factors (Choice B) may contribute to the development of cardiac malformations but are not a common finding in affected children. Clubbing of the fingertips (Choice D) is more commonly associated with chronic respiratory or cardiovascular conditions, rather than symptomatic cardiac malformations.

5. 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.
