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 statement best describes direct contact as a mode of pathogen transmission?

• A. Transmission through large aerosols produced by sneezing or coughing
• B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
• C. Transmission of infectious agents carried by dust
• D. Transmission through skin-to-skin contact or body fluids

Correct answer: D

Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.

3. When assessing a 5-year-old boy with major trauma, his blood pressure is 70/40 mm Hg, and his pulse rate is 140 beats/min and weak. The child's blood pressure:

• A. indicates decompensated shock.
• B. reflects adequate compensation.
• C. suggests increased intracranial pressure.
• D. is appropriate based on his age.

Correct answer: A

Rationale: In a 5-year-old boy with major trauma, a blood pressure of 70/40 mm Hg and a pulse rate of 140 beats/min, and weak, indicate decompensated shock. This presentation signifies inadequate perfusion, leading to compensatory mechanisms being overwhelmed, resulting in decompensated shock. Choice B is incorrect as the vital signs suggest the body is unable to adequately compensate for the trauma. Choice C is incorrect as the vital signs are more indicative of shock rather than increased intracranial pressure. Choice D is incorrect as such low blood pressure is not appropriate for a child of this age and indicates a critical condition.

4. The healthcare provider is providing postpartum care to a client who had a vaginal delivery. Which finding would require further assessment?

• A. Perineal swelling
• B. Moderate lochia serosa
• C. Headache unrelieved by analgesics
• D. Breast engorgement

Correct answer: C

Rationale: A headache unrelieved by analgesics can be a sign of a serious condition such as preeclampsia, which is a life-threatening condition characterized by high blood pressure and often protein in the urine. Prompt assessment and intervention are crucial to prevent complications for both the mother and baby.

5. 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.
