1. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

2. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

3. What is the MOST appropriate method for assessing a small child's level of responsiveness?

• A. Palpate for a radial pulse.
• B. Shout at the child to see if they respond.
• C. Ask the parent about the child's level of responsiveness.
• D. Tap the child and shout, 'Are you okay?'

Correct answer: D

Rationale: When assessing a small child's level of responsiveness, the most appropriate method is to tap the child and shout, 'Are you okay?' This approach is more likely to elicit a response from the child, providing a direct assessment of their level of consciousness and responsiveness. Palpating for a radial pulse (Choice A) is not the most direct method for assessing responsiveness in a child. Shouting at the child (Choice B) may startle them and not provide an accurate assessment. Asking the parent (Choice C) does not directly evaluate the child's responsiveness.

4. 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.

5. What is the appropriate technique for performing two-rescuer CPR on a 4-year-old child?

• A. 15 compressions to 2 ventilations, compressing the sternum with your thumbs, and delivering at least 100 compressions per minute.
• B. 30 compressions to 2 ventilations, compressing the chest one third the depth of the chest, and delivering each breath over 1 second.
• C. 15 compressions to 2 ventilations, compressing the sternum with the heel of your hand, and ventilating until visible chest rise occurs.
• D. 30 compressions to 2 ventilations, compressing the sternum with the heel of both hands, and delivering each breath over 1 to 2 seconds.

Correct answer: C

Rationale: When performing two-rescuer CPR on a 4-year-old child, the appropriate technique involves 15 compressions to 2 ventilations. Compressions should be done by pressing the child's sternum with the heel of your hand. Ventilations should be given until visible chest rise occurs. This technique ensures effective CPR delivery for a child in need of resuscitation.
