1. 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.

2. Why is a prolapsed umbilical cord dangerous?

• A. The cord may be wrapped around the baby's neck, causing strangulation.
• B. The cord might pull the placenta from the uterine wall during delivery.
• C. The baby's head may compress the cord, cutting off its supply of oxygen.
• D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

3. 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.

4. When treating Baby John, who has been diagnosed with a lower respiratory infection, the selection of drugs of choice for the treatment depends primarily on:

• A. Preference of the physician
• B. Selectivity of the organism
• C. Sensitivity of the organism
• D. Tolerance of the client

Correct answer: C

Rationale: The primary factor in selecting drugs for the treatment of a lower respiratory infection in Baby John is the sensitivity of the organism causing the infection. The choice of antibiotics should be guided by the susceptibility of the specific pathogen to ensure effective treatment and prevent resistance.

5. Seizures in children MOST often result from:

• A. a life-threatening infection.
• B. an inflammatory process in the brain.
• C. an abrupt rise in body temperature.
• D. a temperature greater than 102°F.

Correct answer: C

Rationale: Seizures in children most often result from febrile seizures, which are triggered by an abrupt rise in body temperature. Febrile seizures are common in young children, especially between the ages of 6 months to 5 years, and are usually associated with viral infections that cause a sudden spike in body temperature. Choices A, B, and D are incorrect because while infections, inflammatory processes, and high temperatures can sometimes lead to seizures, the most common cause of seizures in children is an abrupt increase in body temperature, known as febrile seizures.
