Nursing Elites

1. Beta-adrenergic agonists such as Salbutamol are given to Reggie, a child with asthma. Such drugs are administered primarily to do which of the following?

• A. Dilate the bronchioles
• B. Reduce secondary infections
• C. Decrease postnasal drip
• D. Reduce airway inflammation

Correct answer: A

Rationale: Beta-adrenergic agonists like Salbutamol are used to dilate the bronchioles in asthma patients. This action helps in relieving bronchospasms and improving airflow to the lungs, making breathing easier for the individual. While reducing inflammation is an essential part of asthma management, beta-adrenergic agonists primarily work by relaxing the smooth muscles around the airways, leading to bronchodilation. Choices B, C, and D are incorrect because beta-adrenergic agonists are not primarily used to reduce secondary infections, decrease postnasal drip, or directly reduce airway inflammation in asthma patients.

2. When is a newborn considered premature?

• A. Weighs less than 6.5 pounds.
• B. Is born to a heroin-addicted mother.
• C. Is born before 37 weeks gestation.
• D. Has meconium in or around its mouth.

Correct answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

3. When assisting ventilations in a 4-year-old child with a bag-valve mask, what should the EMT do?

• A. Deliver each breath over 2 to 3 seconds.
• B. Ensure the appropriate mask size is used.
• C. Block the pop-off valve if needed to achieve adequate chest rise.
• D. Reassess the pulse rate after 60 seconds.

Correct answer: C

Rationale: When assisting ventilations in a 4-year-old child with a bag-valve mask, the EMT should block the pop-off valve if needed to achieve adequate chest rise. This action helps ensure effective ventilation and adequate oxygenation in the child. Blocking the pop-off valve allows for better control over the volume of air delivered and can help maintain positive pressure in the airway, assisting in improving oxygenation and ventilation in the child. Choices A, B, and D are incorrect because delivering each breath over 2 to 3 seconds is a general guideline but may need adjustment based on patient response, ensuring the appropriate mask size is important but not the primary concern in this scenario, and reassessing the pulse rate is not directly related to the ventilation technique being discussed.

4. What comment made by a parent of a 1-month-old would alert the nurse about the presence of a congenital heart defect?

• A. He is always hungry.
• B. He tires out during feedings.
• C. He is fussy for several hours every day.
• D. He sleeps all the time.

Correct answer: B

Rationale: Observing a 1-month-old tiring out during feedings should alert the nurse to the possibility of a congenital heart defect. This symptom may indicate that the infant is expending excess energy to compensate for a heart issue, leading to fatigue during feeding. Choices A, C, and D do not directly relate to a congenital heart defect. Being always hungry, fussy, or sleeping a lot are not specific signs of a congenital heart defect in a 1-month-old.

5. Which of the following is a more reliable indicator of perfusion in children than in adults?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Capillary refill

Correct answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.
