1. What is the MOST effective way to prevent cardiopulmonary arrest in a newborn?

• A. Ensure effective oxygenation and ventilation.
• B. Administer blow-by oxygen as soon as the newborn is born.
• C. Perform an Apgar assessment every 5 minutes.
• D. Suction the newborn's mouth and nose every 3 minutes.

Correct answer: A

Rationale: The most effective way to prevent cardiopulmonary arrest in a newborn is to ensure effective oxygenation and ventilation. This is crucial in maintaining adequate oxygen supply and preventing respiratory distress or failure, which are significant factors leading to cardiopulmonary arrest. Providing appropriate ventilation support and oxygenation can help sustain the newborn's vital functions and reduce the risk of cardiopulmonary compromise.

2. What should be the drop rate per minute using a drop factor of 20 drops/ml?

• A. 19 drops/min
• B. 23 drops/min
• C. 36 drops/min
• D. 46.7 drops/min

Correct answer: A

Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.

3. When inserting an oropharyngeal airway in a small child, what is the preferred method?

• A. Insert the airway with the curvature towards the roof of the mouth and then rotate it 180 degrees.
• B. Insert the airway as you would in an adult, but use an airway that is one size smaller than usual.
• C. Depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue.
• D. Open the airway with the tongue-jaw lift maneuver and insert the airway until slight resistance is met.

Correct answer: C

Rationale: When inserting an oropharyngeal airway in a small child, it is crucial to depress the tongue with a tongue blade and insert the airway with the downward curve facing the tongue. This technique helps in maintaining an open airway and preventing obstruction by the tongue. Placing the airway with the curve facing the roof of the mouth or using a smaller size is not recommended for small children, as it may not effectively keep the airway patent. The tongue-jaw lift maneuver is not the preferred method for inserting an oropharyngeal airway in small children.

4. 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.

5. A child with type 1 diabetes mellitus is brought to the emergency department by the mother, who states that the child has been complaining of abdominal pain and has been lethargic. Diabetic ketoacidosis is diagnosed. Anticipating the plan of care, the nurse prepares to administer which type of intravenous (IV) infusion?

• A. 5% dextrose infusion
• B. Normal saline infusion
• C. NPH insulin infusion
• D. Potassium infusion

Correct answer: B

Rationale: In the management of diabetic ketoacidosis (DKA), the initial intravenous (IV) fluid of choice is normal saline infusion. Normal saline helps to correct dehydration and electrolyte imbalances commonly seen in DKA patients. It does not contain glucose to prevent worsening hyperglycemia or ketoacidosis. NPH insulin infusion is not the initial treatment for DKA; it is typically used after fluid resuscitation. Potassium infusion may be required in DKA to address electrolyte imbalances, but normal saline is the priority for fluid resuscitation.
