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. A 6-year-old child comes to the school nurse reporting a sore throat, and the nurse verifies that the child has a fever and a red, inflamed throat. When a parent of the child arrives at school to take the child home, the nurse urges the parent to seek treatment. The nurse is aware that the causative agent may be beta-hemolytic streptococcus, and the illness may progress to inflamed joints and an infection in the heart. What illness is of most concern to the nurse?

• A. Tetanus
• B. Influenza
• C. Scarlet fever
• D. Rheumatic fever

Correct answer: D

Rationale: Rheumatic fever is the most concerning illness in this case. It can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. If not properly treated, rheumatic fever can lead to serious complications such as inflamed joints and heart infections. Tetanus is caused by a toxin produced by Clostridium tetani bacteria and is not related to the symptoms described in the scenario. Influenza is a viral respiratory illness and does not typically lead to rheumatic fever. While scarlet fever is also caused by streptococcus bacteria, in this case, the symptoms described are more indicative of rheumatic fever than scarlet fever.

3. The nurse is caring for an infant with osteogenesis imperfecta and is providing instruction on how to reduce the risk of injury. Which response from the mother indicates a need for further teaching?

• A. I need to avoid pushing or pulling on an arm or leg.
• B. I must avoid lifting the baby from under the armpits.
• C. I should not bend an arm or leg into an awkward position.
• D. We must avoid lifting the legs by the ankles to change diapers.

Correct answer: B

Rationale: Lifting the baby from under the armpits can cause fractures in infants with osteogenesis imperfecta. The correct approach is to support the baby's body and head carefully, avoiding pressure on vulnerable areas prone to fractures. Choices A, C, and D demonstrate proper awareness of caring for an infant with osteogenesis imperfecta by emphasizing caution to prevent fractures.

4. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

5. Which of the following signs or symptoms is more common in children than adults following head trauma?

• A. nausea and vomiting
• B. altered mental status
• C. tachycardia and diaphoresis
• D. changes in pupillary reaction

Correct answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less skull compliance and higher brain water content, making them more susceptible to developing symptoms like nausea and vomiting. Altered mental status (choice B) can occur in both children and adults but is not more common in children. Tachycardia and diaphoresis (choice C) are nonspecific and can occur in both age groups. Changes in pupillary reaction (choice D) are not typically more common in children following head trauma compared to adults.
