1. When is it MOST appropriate to clamp and cut the umbilical cord?

A. Before the newborn has taken its first breath
B. After the placenta has completely delivered
C. As soon as the cord has stopped pulsating
D. Immediately following delivery of the newborn

Correct answer: C

Rationale: The ideal time to clamp and cut the umbilical cord is when it has stopped pulsating. This allows for the transfer of remaining blood from the placenta to the newborn, which can be beneficial for the baby's health and iron stores. Clamping the cord too early can deprive the newborn of this essential blood volume. Waiting for the pulsations to cease ensures that the baby receives the maximum benefits from delayed cord clamping.

2. A 3-year-old boy is found to be in cardiopulmonary arrest. As you begin one-rescuer CPR, your partner prepares the AED. What is the appropriate compression to ventilation ratio for this child?

A. 3:01
B. 30:2
C. 15:2
D. 5:1

Correct answer: B

Rationale: The correct compression to ventilation ratio for a single rescuer performing CPR on a child is 30:2. This ratio ensures adequate circulation and oxygenation during CPR. 30 compressions help maintain blood flow, while 2 rescue breaths provide oxygenation. Choice A (3:01) is incorrect as it does not follow the standard CPR guidelines for children. Choice C (15:2) is incorrect as it is the ratio used for adult CPR. Choice D (5:1) is incorrect as it is not the recommended ratio for child CPR.

3. You are treating a 5-year-old child who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. Supplemental oxygen has been given, and you have elevated his lower extremities. En route to the hospital, you note that his work of breathing has increased. You should:

A. begin positive-pressure ventilations and reassess the child.
B. lower the extremities and reassess the child.
C. listen to the lungs with a stethoscope for abnormal breath sounds.
D. insert a nasopharyngeal airway and increase the oxygen flow.

Correct answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.

4. The healthcare provider assesses the newborn's ears to be parallel to the outer and inner canthus of the eye. The healthcare provider documents this finding to be which of the following?

A. A normal position
B. A possible chromosomal abnormality
C. Facial paralysis
D. Prematurity

Correct answer: A

Rationale: When the top of the ear (pinna) is parallel to the outer and inner canthus of the eye, it is considered a normal position in a newborn. This alignment is an important assessment to ensure normal development and anatomy. Choices B, C, and D are incorrect because the parallel alignment of the ears to the outer and inner canthus of the eye is not indicative of a possible chromosomal abnormality, facial paralysis, or prematurity. It is simply a normal anatomical finding in a newborn.

5. What should you do immediately upon delivery of a newborn's head?

A. Suction the nose.
B. Dry the face.
C. Cover the eyes.
D. Suction the mouth.

Correct answer: D

Rationale: Upon delivery of a newborn's head, the priority is to clear the airway to ensure proper breathing. Suctioning the mouth takes precedence over suctioning the nose or other actions to prevent potential airway obstruction. Choice D is the correct answer as it addresses the immediate need to maintain a clear airway for the newborn. Choices A, B, and C are not the correct actions to take at this moment as they do not directly address the crucial need to establish a clear airway for the newborn.
