1. How should you assist with the delivery of the baby's head?
- A. Grasping each side of the baby's head and gently pulling to facilitate delivery.
- B. Placing your fingers on the bony part of the skull and applying gentle pressure.
- C. Carefully rotating the baby's head to face up during delivery.
- D. Placing the palm of your hand firmly against the back of the baby's skull.
Correct answer: B
Rationale: To assist with the delivery of the baby's head, the correct technique involves placing your fingers on the bony part of the skull and applying gentle pressure. This method helps guide the baby's head through the birth canal safely and effectively. Choices A, C, and D are incorrect. Grasping and pulling the baby's head, rotating the head, or placing the palm of your hand against the back of the baby's skull can potentially cause harm or complications during delivery.
2. 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.
3. What is the appropriate ventilation rate for an apneic infant?
- A. 8 to 10 breaths/min.
- B. 10 to 12 breaths/min.
- C. 12 to 20 breaths/min.
- D. 20 to 30 breaths/min.
Correct answer: C
Rationale: During resuscitation of an apneic infant, the appropriate ventilation rate is 12 to 20 breaths per minute. This rate helps provide adequate oxygenation and ventilation without causing harm to the infant. Choice A (8 to 10 breaths/min) is too low and may not provide sufficient ventilation. Choice B (10 to 12 breaths/min) is slightly below the recommended range, which may not be optimal for effective resuscitation. Choice D (20 to 30 breaths/min) is too high and may lead to overventilation and potential harm to the infant by causing hypocapnia.
4. When is a newborn considered premature?
- A. Weighs less than 6.5 pounds.
- B. Is born to a heroin-addicted mother.
- C. Is born before 37 weeks gestation.
- D. Has meconium in or around its mouth.
Correct answer: C
Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.
5. Which of the following is a more reliable indicator of perfusion in children than in adults?
- A. Blood pressure
- B. Heart rate
- C. Respiratory rate
- D. Capillary refill
Correct answer: D
Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.
