Nursing Elites

1. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

2. Fred is a 12-year-old boy diagnosed with pneumococcal pneumonia. Which of the following would Nurse Nica expect to assess?

• A. Mild cough
• B. Slight fever
• C. Chest pain
• D. Bulging fontanel

Correct answer: C

Rationale: Chest pain is a common symptom seen in patients with pneumococcal pneumonia. It can result from inflammation of the pleura or irritation of the diaphragm due to the infection. While cough and fever are also common symptoms, chest pain is particularly significant in pneumonia cases as it can be a distressing symptom for the patient and may indicate complications or severity of the infection. Bulging fontanel, on the other hand, is more indicative of conditions affecting infants and is not typically associated with pneumococcal pneumonia in a 12-year-old boy.

3. What is the appropriate ventilation rate for an apneic infant?

• A. 8 to 10 breaths/min.
• B. 10 to 12 breaths/min.
• C. 12 to 20 breaths/min.
• D. 20 to 30 breaths/min.

Correct answer: C

Rationale: During resuscitation of an apneic infant, the appropriate ventilation rate is 12 to 20 breaths per minute. This rate helps provide adequate oxygenation and ventilation without causing harm to the infant. Choice A (8 to 10 breaths/min) is too low and may not provide sufficient ventilation. Choice B (10 to 12 breaths/min) is slightly below the recommended range, which may not be optimal for effective resuscitation. Choice D (20 to 30 breaths/min) is too high and may lead to overventilation and potential harm to the infant by causing hypocapnia.

4. When is a newborn considered premature?

• A. Weighs less than 6.5 pounds.
• B. Is born to a heroin-addicted mother.
• C. Is born before 37 weeks gestation.
• D. Has meconium in or around its mouth.

Correct answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

5. 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.
