Nursing Elites

1. Which of the following findings is abnormal?

• A. Rapid, irregular breathing in a newly born infant
• B. Heart rate of 80 beats/min in a 3-month-old infant
• C. Respiratory rate of 26 breaths/min in a 2-year-old child
• D. Systolic BP of 100 mm Hg in a 10-year-old child

Correct answer: B

Rationale: A heart rate of 80 beats per minute in a 3-month-old infant is abnormally low for that age group and could indicate underlying health issues. The normal heart rate for a 3-month-old infant is typically higher, around 100-150 beats per minute. Therefore, this finding stands out as abnormal and warrants further evaluation. Choice A is not necessarily abnormal in a newly born infant as irregular breathing patterns can be common during the neonatal period. Choice C falls within the normal respiratory rate range for a 2-year-old child, which is around 20-30 breaths per minute. Choice D reflects a systolic blood pressure value within the normal range for a 10-year-old child, which is typically around 90-110 mm Hg.

2. A clinic nurse reviews the record of a child just seen by a doctor and diagnosed with suspected aortic stenosis. The nurse expects to note documentation of which clinical manifestation specifically found in this disorder?

• A. Pallor
• B. Hyperactivity
• C. Exercise intolerance
• D. Gastrointestinal disturbances

Correct answer: C

Rationale: Aortic stenosis is a condition characterized by the narrowing of the aortic valve, leading to reduced blood flow from the heart to the body. This narrowing restricts the amount of oxygenated blood that can reach various tissues, including muscles. As a result, individuals with aortic stenosis may experience exercise intolerance, as their muscles may not receive an adequate oxygen supply during physical activity. This can manifest as fatigue, shortness of breath, and overall decreased exercise capacity. Pallor (choice A) is a pale appearance that may be seen in anemia or other conditions affecting blood flow but is not specific to aortic stenosis. Hyperactivity (choice B) and gastrointestinal disturbances (choice D) are not typically associated with aortic stenosis.

3. When ventilating an apneic 3-year-old child with a bag-valve mask device, what is the MOST important action to take?

• A. Avoid hyperventilation and ensure adequate chest rise.
• B. Squeeze the bag with both hands and use a pediatric mask.
• C. Immediately insert an oropharyngeal airway.
• D. Provide one breath every 3 to 5 seconds.

Correct answer: A

Rationale: When ventilating an apneic child, the most important action is to avoid hyperventilation and ensure adequate chest rise. Hyperventilation can lead to decreased cardiac output and increased intracranial pressure. Adequate chest rise confirms effective ventilation and minimizes the risk of complications. Choice B is incorrect because using both hands to squeeze the bag may not ensure proper ventilation and can lead to complications. Choice C is incorrect as inserting an oropharyngeal airway is not the initial action in ventilating an apneic child with a bag-valve mask. Choice D is incorrect as providing ventilations every 3 to 5 seconds may not be appropriate for effective ventilation in a pediatric patient.

4. Seizures in children MOST often result from:

• A. a life-threatening infection.
• B. an inflammatory process in the brain.
• C. an abrupt rise in body temperature.
• D. a temperature greater than 102°F.

Correct answer: C

Rationale: Seizures in children most often result from febrile seizures, which are triggered by an abrupt rise in body temperature. Febrile seizures are common in young children, especially between the ages of 6 months to 5 years, and are usually associated with viral infections that cause a sudden spike in body temperature. Choices A, B, and D are incorrect because while infections, inflammatory processes, and high temperatures can sometimes lead to seizures, the most common cause of seizures in children is an abrupt increase in body temperature, known as febrile seizures.

5. Which of the following is not an infectious cause of diarrhea?

• A. Allergy
• B. Bacteria
• C. Parasite
• D. Virus

Correct answer: A

Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.
