Which of the following statements regarding 2-rescuer child CPR is correct?
- A. The chest should be compressed with one hand, and a compression-to-ventilation ratio of 30:2 should be used.
- B. The chest should not be allowed to fully recoil in between compressions.
- C. A compression-to-ventilation ratio of 15:2 should be used if an advanced airway is in place.
- D. Compress the chest with one or two hands to a depth equal to one-third the diameter of the chest.
Correct Answer: D
Rationale: During 2-rescuer child CPR, it is important to compress the chest with one or two hands to a depth equal to one-third the diameter of the chest. This technique ensures effective chest compressions are being delivered to help circulate blood and oxygenate the child's body. Choice A is incorrect because both hands should be used for chest compressions in 2-rescuer CPR. Choice B is incorrect as allowing the chest to fully recoil between compressions is essential to create negative pressure and facilitate blood flow back to the heart. Choice C is incorrect as the standard compression-to-ventilation ratio for child CPR is 30:2, regardless of whether an advanced airway is in place.

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.
When ventilating an apneic 3-year-old child with a bag-valve mask device, what is the MOST important action to take?
- A. Avoid hyperventilation and ensure adequate chest rise.
- B. Squeeze the bag with both hands and use a pediatric mask.
- C. Immediately insert an oropharyngeal airway.
- D. Provide one breath every 3 to 5 seconds.
Correct Answer: A
Rationale: When ventilating an apneic child, the most important action is to avoid hyperventilation and ensure adequate chest rise. Hyperventilation can lead to decreased cardiac output and increased intracranial pressure. Adequate chest rise confirms effective ventilation and minimizes the risk of complications. Choice B is incorrect because using both hands to squeeze the bag may not ensure proper ventilation and can lead to complications. Choice C is incorrect as inserting an oropharyngeal airway is not the initial action in ventilating an apneic child with a bag-valve mask. Choice D is incorrect as providing ventilations every 3 to 5 seconds may not be appropriate for effective ventilation in a pediatric patient.
What is the proper depth of chest compressions for a 9-month-old infant?
- A. 1/3 the diameter of the chest or about 1 1/2 inches.
- B. 1/4 the diameter of the chest or about 1 inch.
- C. 1/2 the diameter of the chest or about 2 inches.
- D. 1/3 the diameter of the chest or about 3/4 inch.
Correct Answer: A
Rationale: When performing chest compressions on a 9-month-old infant, the proper depth is 1/3 the diameter of the chest, which equates to approximately 1 1/2 inches. This depth is crucial for effective cardiopulmonary resuscitation (CPR) in infants. Choice B, which suggests 1/4 the diameter of the chest or about 1 inch, is incorrect as it does not provide the recommended depth for infants. Choice C, stating 1/2 the diameter of the chest or about 2 inches, is too deep and may cause harm to the infant. Choice D, mentioning 1/3 the diameter of the chest or about 3/4 inch, is also incorrect as it underestimates the required depth for effective chest compressions on a 9-month-old infant.
When assessing a 30-year-old female who was sexually assaulted, what is the MOST important action for you to take?
- A. Have a female healthcare provider perform the assessment.
- B. Advise against showering or changing clothes.
- C. Acknowledge that the patient is a potential crime scene.
- D. Ensure that all life-threatening injuries are treated.
Correct Answer: D
Rationale: In cases of sexual assault, the priority is to address any life-threatening injuries first before proceeding with other aspects of care. Although preserving evidence and approaching the situation with sensitivity are crucial, immediate treatment of life-threatening conditions takes precedence to ensure the patient's well-being and safety. Having a female healthcare provider, advising against showering or changing clothes, and acknowledging the patient as a potential crime scene are important but secondary considerations compared to addressing any life-threatening injuries promptly.
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.
