Nursing Elites

1. 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.

2. 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.

3. What assessment finding places a newborn at risk for developing physiologic jaundice?

• A. Cephalohematoma
• B. Mongolian spots
• C. Telangiectatic nevi
• D. Molding

Correct answer: A

Rationale: The correct answer is A, Cephalohematoma. Physiologic jaundice in newborns can occur due to the breakdown of excess red blood cells. A cephalohematoma, a collection of blood caused by ruptured blood vessels between a cranial bone's surface and periosteal membrane, can lead to increased red blood cell breakdown. This increased breakdown can contribute to the development of physiologic jaundice in newborns. Choices B, Mongolian spots, and C, Telangiectatic nevi, are both benign skin conditions and are not directly associated with increased red blood cell breakdown. Choice D, Molding, refers to the shaping of the fetal head during passage through the birth canal and is not related to the development of physiologic jaundice.

4. How can the nurse best assess that the parents demonstrate understanding of the dressing change procedure prior to discharge for their child with burns?

• A. The parents explaining the importance of using sterile technique to the nurse.
• B. The nurse observing the parents changing the dressing using appropriate technique.
• C. The parents observing the nurse changing the dressing and confirming their understanding of the procedure.
• D. The nurse allowing the parents to explain the dressing change procedure and perform it in private to boost their confidence.

Correct answer: B

Rationale: The most effective way for the nurse to assess the parents' understanding of the dressing change procedure is by observing them as they change the dressing using the correct technique. This direct observation ensures that the parents are able to perform the task correctly and confidently before discharge. Merely verbalizing or explaining the procedure may not accurately reflect the parents' competency in performing the actual task. Choice A involves the parents explaining to the nurse, which does not directly assess their practical skills. Choice C suggests the parents observing the nurse, which does not evaluate the parents' ability to perform the task independently. Choice D focuses on boosting the parents' confidence but does not directly assess their understanding and competency in performing the dressing change.

5. 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.
