Nursing Elites

1. What is an important nursing consideration for a child with a diagnosis of juvenile idiopathic arthritis (JIA) being treated with methotrexate?

• A. Monitor liver function tests regularly
• B. Encourage regular exercise
• C. Provide high-calorie snacks
• D. Encourage frequent handwashing

Correct answer: A

Rationale: The correct answer is to monitor liver function tests regularly. Methotrexate, commonly used in JIA, can be hepatotoxic. Regular monitoring of liver function tests is crucial to detect any signs of liver damage early. While encouraging regular exercise (choice B) is generally beneficial for overall health, it is not directly related to methotrexate therapy. Providing high-calorie snacks (choice C) is not a necessary consideration in this context and can be misleading. Encouraging frequent handwashing (choice D) is important for infection control but is not specifically related to the medication methotrexate.

2. 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.

3. An infant who has had diarrhea for 3 days is admitted in a lethargic state and is breathing rapidly. The parent states that the baby has been ingesting formula, although not as much as usual, and cannot understand the sudden change. What explanation should the nurse give the parent?

• A. Cellular metabolism is unstable in young children.
• B. The proportion of water in the body is less than in adults.
• C. Renal function is immature in children until they reach school age.
• D. The extracellular fluid requirement per unit of body weight is greater than in adults.

Correct answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect as cellular metabolism instability does not directly relate to the infant's condition described. Choice B is inaccurate as the proportion of water in the body is not the primary issue causing the infant's symptoms. Choice C is incorrect as renal function being immature does not explain the sudden change in the infant's health status; it is more related to fluid balance and dehydration.

4. The healthcare professional is developing a teaching plan for a child who is to have their cast removed. What instruction would the professional most likely include?

• A. Applying petroleum jelly to the dry skin.
• B. Rubbing the skin vigorously to remove the dead skin.
• C. Soaking the area in warm water every day.
• D. Washing the skin with diluted peroxide and water.

Correct answer: C

Rationale: Soaking the area in warm water is the most appropriate instruction for a child who is having their cast removed. This method helps to gently remove dead skin without causing irritation. Applying petroleum jelly to dry skin (Choice A) is not recommended as it may not effectively aid in the removal of dead skin. Rubbing the skin vigorously (Choice B) can lead to skin irritation and should be avoided. Washing the skin with diluted peroxide and water (Choice D) may be too harsh, causing unnecessary irritation to the skin post-cast removal.

5. The nurse is teaching a father how to stimulate his 7-year-old son, who has a 'slow-to-warm-up' temperament. Which guidance will be most successful?

• A. Telling him to read stories to the child about famous athletes
• B. Suggesting he take the child to watch him play softball
• C. Urging him to sign the child up for little league football
• D. Proposing wrestling with the child and letting him win

Correct answer: A

Rationale: The correct answer is A. Reading stories to the child about famous athletes would be the most successful guidance for a child with a 'slow-to-warm-up' temperament. This approach allows for a less active and more acceptable way of engaging with the child, aligning better with the child's temperament. Choices B, C, and D involve more active and potentially overwhelming activities for a child with such a temperament, which may not be as effective in stimulating and engaging the child.
