Nursing Elites

1. Upon assessing a newborn immediately after delivery, you note that the infant is breathing spontaneously and has a heart rate of 90 beats/min. What is the most appropriate initial management for this newborn?

• A. begin positive pressure ventilations
• B. provide blow-by oxygen with oxygen tubing
• C. assess the newborn's skin condition and color
• D. start chest compressions and contact medical control

Correct answer: A

Rationale: A heart rate below 100 beats/min in a newborn indicates the need for positive pressure ventilation to improve oxygenation. Providing positive pressure ventilations helps in assisting the newborn's breathing efforts to ensure adequate oxygenation. Choice B, providing blow-by oxygen, may not be sufficient to address the underlying issue of inadequate breathing. Choice C, assessing the newborn's skin condition and color, is important but not the most immediate action needed for a heart rate below 100 beats/min. Choice D, starting chest compressions, is not indicated as the infant is breathing spontaneously and has a heart rate, albeit lower than normal, which does not warrant chest compressions.

2. What factor predisposes the urinary tract to infection in children?

• A. increased fluid intake
• B. short urethra in young girls
• C. prostatic secretions in males
• D. frequent emptying of the bladder

Correct answer: B

Rationale: The short urethra in young girls predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.

3. 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 sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

4. A newborn with an anorectal anomaly had an anoplasty performed. At the 2-week follow-up visit, a series of anal dilations are begun. What should the nurse recommend to the parents to help prevent the infant from becoming constipated?

• A. Use a soy formula.
• B. Breastfeed if possible.
• C. Administer a suppository nightly.
• D. Offer glucose water between feedings.

Correct answer: B

Rationale: Breastfeeding is the best recommendation to help prevent constipation in infants. Breast milk is easily digestible and contains the right balance of nutrients, which can lead to softer stools, thus reducing the likelihood of constipation. Offering a soy formula (Choice A) may not necessarily prevent constipation as effectively as breast milk due to differences in nutrient composition. Administering a suppository nightly (Choice C) is not a routine measure for preventing constipation in infants and may not be suitable for regular use in this scenario. Offering glucose water (Choice D) between feedings is not recommended as it does not provide the necessary nutrients found in breast milk, which are essential for preventing constipation and promoting overall health in newborns.

5. The parents of a child with asthma ask the nurse how they can help their child prevent asthma attacks. What should the nurse advise?

• A. Avoid exposure to allergens
• B. Encourage regular exercise
• C. Provide a high-protein diet
• D. Increase fluid intake

Correct answer: A

Rationale: The correct answer is to advise the parents to avoid exposure to allergens. Asthma attacks are often triggered by allergens such as dust mites, pollen, pet dander, and mold. By minimizing the child's exposure to these triggers, the likelihood of asthma attacks can be reduced. Encouraging regular exercise is beneficial for overall health but may not directly prevent asthma attacks. Providing a high-protein diet and increasing fluid intake are important for general well-being but do not specifically address asthma prevention.
