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. During the 5-minute Apgar assessment of a newborn, you note a heart rate of 130 beats/min, cyanosis in the hands and feet, and rapid respirations. The baby cries when you flick the soles of its feet and resists leg straightening. These findings correspond to an Apgar score of:

• A. 9
• B. 7
• C. 8
• D. 10

Correct answer: A

Rationale: The Apgar score is a rapid assessment tool to evaluate the newborn's transition to life outside the womb. The Apgar score is based on five components: heart rate (>100 bpm), respiratory effort (rapid breathing), muscle tone (resisting leg straightening), reflex irritability (crying when feet are flicked), and color (cyanosis to extremities). The described findings match a score of 9, indicating good overall condition and adaptation to extrauterine life.

3. What is the MOST effective way to prevent cardiopulmonary arrest in a newborn?

• A. Ensure effective oxygenation and ventilation.
• B. Administer blow-by oxygen as soon as the newborn is born.
• C. Perform an Apgar assessment every 5 minutes.
• D. Suction the newborn's mouth and nose every 3 minutes.

Correct answer: A

Rationale: The most effective way to prevent cardiopulmonary arrest in a newborn is to ensure effective oxygenation and ventilation. This is crucial in maintaining adequate oxygen supply and preventing respiratory distress or failure, which are significant factors leading to cardiopulmonary arrest. Providing appropriate ventilation support and oxygenation can help sustain the newborn's vital functions and reduce the risk of cardiopulmonary compromise.

4. When using the Ballard gestational assessment tool on a newborn, which of the following tests should be performed after the first hour of birth, allowing the newborn to recover from the stress of birth?

• A. Arm recoil
• B. Square window sign
• C. Scarf sign
• D. Popliteal angle

Correct answer: A

Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.

5. Where is the most appropriate location to perform a procedure on a preschooler?

• A. Perform the procedure in the child's hospital bed.
• B. Perform the procedure in the treatment room.
• C. Allow the child to decide when the procedure will be performed.
• D. Ask the parents to help restrain the child so the procedure can be performed.

Correct answer: B

Rationale: When performing a procedure on a preschooler, it is most appropriate to do so in the treatment room. This setting is specifically designed to provide a suitable environment with necessary equipment and resources to ensure the procedure is carried out safely and efficiently. It helps minimize distractions and provides a controlled environment for healthcare providers to focus on the child's needs. Choices A, C, and D are incorrect because performing the procedure in the child's hospital bed may lack the necessary resources and equipment, allowing the child to decide when the procedure will be performed may not be feasible due to medical necessity and urgency, and asking parents to help restrain the child is not ideal as it may not provide a professional and controlled setting for the procedure.
