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. Which of the following parameters would be LEAST reliable when assessing the perfusion status of a 2-year-old child with possible shock?

• A. distal capillary refill
• B. systolic blood pressure
• C. skin color and temperature
• D. presence of peripheral pulses

Correct answer: B

Rationale: Systolic blood pressure is the least reliable parameter when assessing the perfusion status of a 2-year-old child with possible shock. In pediatric patients, especially young children, blood pressure may not decrease until significant shock has already occurred, making it a late indicator of inadequate perfusion. Depending solely on systolic blood pressure to evaluate perfusion status in this age group can lead to a delay in appropriate interventions. Distal capillary refill time, skin color, and temperature changes, and the presence of peripheral pulses are more sensitive and early indicators of perfusion status in pediatric patients. Monitoring distal capillary refill provides information on peripheral perfusion, while changes in skin color and temperature can signal circulatory compromise. Evaluating the presence or absence of peripheral pulses offers insights into vascular perfusion. These parameters offer more reliable and prompt feedback on a child's perfusion status compared to systolic blood pressure.

3. Surgical repair for patent ductus arteriosus (PDA) is done to prevent the complication of

• A. pulmonary infection
• B. right-to-left shunt of blood
• C. decreased workload on left side of the heart
• D. increased pulmonary vascular congestion

Correct answer: D

Rationale: The correct answer is D: increased pulmonary vascular congestion. Surgical repair of patent ductus arteriosus (PDA) aims to prevent the complications associated with increased pulmonary vascular congestion, such as pulmonary hypertension and heart failure. Choice A, pulmonary infection, is not a direct complication of PDA but can occur secondary to other conditions. Choice B, right-to-left shunt of blood, is a feature of some congenital heart defects but not a direct complication of PDA. Choice C, decreased workload on the left side of the heart, is not a primary reason for surgical repair of PDA, as the main concern is the impact on pulmonary circulation.

4. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the healthcare provider?

• A. 100 to 150 mL
• B. 155 to 250 mL
• C. 255 to 360 mL
• D. 365 to 500 mL

Correct answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL. This range is considered safe to prevent overdistension and potential harm to the child's rectum. Choices A, C, and D exceed the safe range for a 2-year-old child and can lead to complications such as bowel perforation or electrolyte imbalances.

5. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.
