Nursing Elites

1. You are dispatched to a residence for a child with respiratory distress. The child is wheezing and has nasal flaring and retractions. His oxygen saturation is 92%. You should:

• A. place the child in a supine position.
• B. administer high-flow oxygen.
• C. begin chest compressions.
• D. administer low-flow oxygen.

Correct answer: B

Rationale: In a scenario where a child presents with respiratory distress, wheezing, nasal flaring, retractions, and an oxygen saturation of 92%, the appropriate intervention is to administer high-flow oxygen. This helps to improve oxygenation and alleviate the respiratory distress the child is experiencing. Placing the child in a supine position can worsen their condition by affecting their ability to breathe effectively. Chest compressions are not indicated in this case as the child is not in cardiac arrest. Administering low-flow oxygen may not provide adequate oxygenation for a child in respiratory distress with a saturation of 92%. Therefore, the priority is to administer high-flow oxygen to improve oxygen levels and support the child's breathing.

2. When assessing a 30-year-old female in labor, what should the EMT do?

• A. Ask the mother when she is expecting to deliver.
• B. Avoid questioning the patient about her medical history.
• C. Determine the stage of her labor by examining her.
• D. Recall that delivery is imminent if she is crowning.

Correct answer: D

Rationale: During the assessment of a 30-year-old female in labor, the EMT should be aware that delivery is imminent if she is crowning. Crowning indicates that the baby's head is visible at the vaginal opening, signaling that the birth is progressing rapidly and the baby will soon be delivered. This is a critical moment that requires preparedness for the birth process and ensuring a safe delivery environment. Choice A is incorrect because asking the mother when she is expecting to deliver is not relevant when the baby's head is visible at the vaginal opening. Choice B is incorrect as obtaining the patient's medical history is essential for providing appropriate care. Choice C is incorrect because determining the stage of labor by examining the patient is important but recognizing crowning indicates that delivery is imminent and requires immediate action.

3. 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.

4. Which of the following is not an infectious cause of diarrhea?

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

Correct answer: A

Rationale: The correct answer is A: Allergy. Allergy is not an infectious cause of diarrhea. Diarrhea caused by bacteria, parasites, and viruses is due to infection, while an allergy triggers an immune response that can lead to diarrhea but is not caused by an infectious agent. Choices B, C, and D are incorrect because bacteria, parasites, and viruses are known infectious causes of diarrhea, resulting from infections by these microorganisms.

5. 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.
