1. Which of the following are not infectious causes of diarrhea?

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

Correct answer: A

Rationale: Diarrhea can be caused by various infectious agents such as bacteria, parasites, and viruses. Allergy, on the other hand, is a non-infectious cause of diarrhea. When an individual with a food allergy consumes the specific food they are allergic to, it can trigger diarrhea as a part of the allergic reaction.

2. Why is a prolapsed umbilical cord dangerous?

• A. The cord may be wrapped around the baby's neck, causing strangulation.
• B. The cord might pull the placenta from the uterine wall during delivery.
• C. The baby's head may compress the cord, cutting off its supply of oxygen.
• D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

3. When discussing heart conditions, a healthcare provider explains a condition in which the lungs retain extra fluid due to left ventricular impairment. What is this condition?

• A. Whooping cough
• B. Pneumonia
• C. Asthma
• D. Pulmonary edema

Correct answer: D

Rationale: Pulmonary edema is the correct answer. It is a condition characterized by the retention of extra fluid in the lungs, often due to left ventricular impairment. This fluid buildup can lead to symptoms such as shortness of breath, coughing, and difficulty breathing. Whooping cough (Choice A), pneumonia (Choice B), and asthma (Choice C) are not conditions related to the retention of fluid in the lungs due to left ventricular impairment. Whooping cough is a bacterial respiratory infection, pneumonia is an infection that inflames the air sacs in one or both lungs, and asthma is a chronic respiratory condition characterized by airway inflammation and constriction.

4. The healthcare provider is teaching a new mother how to care for her newborn's umbilical cord. Which instruction should be included?

• A. Keep the cord dry and exposed to air
• B. Clean the cord with alcohol at every diaper change
• C. Cover the cord with a sterile dressing
• D. Submerge the cord in water during baths

Correct answer: A

Rationale: Keeping the umbilical cord dry and exposed to air is the correct instruction because it promotes faster healing. Moisture can delay the healing process and increase the risk of infection. Cleaning the cord with alcohol at every diaper change or covering it with a sterile dressing can actually impede the healing process by preventing airflow. Submerging the cord in water during baths is not recommended as it can introduce moisture and increase the risk of infection.

5. 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.
