1. What is the main function of the uterus?
- A. Dilate and expel the baby from the cervix.
- B. House the fetus as it grows for 40 weeks.
- C. Provide a cushion and protect the fetus from infection.
- D. Provide oxygen and other nutrients to the fetus.
Correct answer: B
Rationale: The main function of the uterus is to house and nurture the growing fetus for approximately 40 weeks during pregnancy. It provides the necessary environment for the fetus to develop and grow until it is ready for birth. Choice A is incorrect as the cervix, not the uterus, dilates during labor to allow the baby to pass through. Choice C is incorrect as while the uterus does provide a protective environment, its primary function is not to act as a cushion. Choice D is incorrect as the placenta, not the uterus, is responsible for providing oxygen and nutrients to the fetus.
2. Which of the following is an abnormal finding when assessing the abdomen of a newborn?
- A. The umbilical cord has two arteries and one vein.
- B. The presence of green vomit.
- C. The liver is palpable 1 to 2 cm below the costal margin.
- D. The abdomen is soft and nondistended.
Correct answer: B
Rationale: The correct answer is B. The presence of green vomit in a newborn is an abnormal finding and indicates a possible intestinal obstruction. This finding requires immediate attention and further investigation. Choices A, C, and D are normal findings in a newborn's abdomen assessment. A newborn typically has an umbilical cord with two arteries and one vein, a liver that may be palpable 1 to 2 cm below the costal margin due to its normal size in a neonate, and a soft, nondistended abdomen as expected in healthy newborns.
3. Your assessment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?
- A. Dry the infant briskly.
- B. Suction the mouth.
- C. Begin artificial ventilations.
- D. Begin chest compressions.
Correct answer: C
Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.
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 3-year-old boy is found to be in cardiopulmonary arrest. As you begin one-rescuer CPR, your partner prepares the AED. What is the appropriate compression to ventilation ratio for this child?
- A. 3:01
- B. 30:2
- C. 15:2
- D. 5:1
Correct answer: B
Rationale: The correct compression to ventilation ratio for a single rescuer performing CPR on a child is 30:2. This ratio ensures adequate circulation and oxygenation during CPR. 30 compressions help maintain blood flow, while 2 rescue breaths provide oxygenation. Choice A (3:01) is incorrect as it does not follow the standard CPR guidelines for children. Choice C (15:2) is incorrect as it is the ratio used for adult CPR. Choice D (5:1) is incorrect as it is not the recommended ratio for child CPR.
