1. How will a ventricular septal defect affect blood flow?
- A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
- B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
- C. No shunting occurs due to high pressure in the left ventricle.
- D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.
Correct answer: A
Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.
2. After the baby's head delivers, how is it usually tilted?
- A. with the face up.
- B. anteriorly, with the chin up.
- C. posteriorly, to one side.
- D. posteriorly, face down.
Correct answer: C
Rationale: After the baby's head delivers, it is typically tilted posteriorly to one side to help facilitate the delivery of the shoulders. This positioning is important for the safe and smooth delivery of the baby.
3. Which of the following parameters is the LEAST reliable when assessing the perfusion status of a 2-year-old child?
- A. Capillary refill time
- B. Presence of peripheral pulses
- C. Skin color and temperature
- D. Systolic blood pressure
Correct answer: D
Rationale: Systolic blood pressure is the least reliable parameter when assessing perfusion status in a 2-year-old child. In young children, blood pressure measurements can be variable, affected by factors like anxiety or crying. Capillary refill time, presence of peripheral pulses, and skin color and temperature are more reliable indicators of perfusion status in this age group.
4. 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.
5. Jaundice in children can be either pathological or physiological. Which of these will you consider as more serious?
- A. Jaundice seen within 24 hours of life
- B. Jaundice seen at the palms and soles
- C. Jaundice appearing after 24 hours of life
- D. Jaundice seen after 14 days of life
Correct answer: A
Rationale: Jaundice seen within 24 hours of life is considered more serious in children as it can indicate pathological causes such as hemolytic disease or sepsis, which require prompt evaluation and management to prevent complications. Jaundice appearing within 24 hours of life is concerning due to the higher likelihood of severe conditions, while jaundice seen at the palms and soles is more likely due to physiological causes such as breast milk jaundice. Jaundice appearing after 24 hours or after 14 days of life may still require evaluation but is less urgent compared to jaundice within the first 24 hours.
