Which cardiac defects are associated with tetralogy of Fallot?
- A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
- B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
- C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
- D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect
Correct Answer: C
Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.

A 3-year-old child has a sudden onset of respiratory distress. The mother denies any recent illnesses or fever. You should suspect
- A. croup
- B. epiglottitis
- C. lower respiratory infection
- D. foreign body airway obstruction
Correct Answer: D
Rationale: In a 3-year-old child presenting with sudden respiratory distress without fever or recent illness, the most likely cause is a foreign body airway obstruction. Foreign body airway obstruction can lead to a sudden onset of respiratory distress as it blocks the air passage. Croup typically presents with a barking cough and stridor, often preceded by a viral illness. Epiglottitis is characterized by high fever, drooling, and a muffled voice. Lower respiratory infections usually present with symptoms such as cough, fever, and chest congestion. Therefore, in this case, the absence of recent illness or fever makes foreign body airway obstruction the most likely cause of the respiratory distress.
At 0345, you receive a call for a woman in labor. Upon arriving at the scene, you are greeted by a very anxious man who tells you that his wife is having her baby 'now.' This man escorts you into the living room where a 25-year-old woman is lying on the couch in obvious pain. After determining that delivery is not imminent, you begin transport. While en route, the mother tells you that she feels the urge to push. You assess her and see the top of the baby's head bulging from the vagina. What is your most appropriate first action?
- A. allow the head to deliver and check for the location of the cord
- B. advise your partner to stop the ambulance and assist with the delivery
- C. tell the mother to take short, quick breaths until you arrive at the hospital
- D. prepare the mother for an emergency delivery and open the obstetrics kit
Correct Answer: B
Rationale: The correct action in this scenario is to advise your partner to stop the ambulance and assist with the delivery. When the mother feels the urge to push and you see the baby's head bulging from the vagina, it indicates an imminent delivery. Stopping the ambulance allows for a safer environment for the delivery of the baby and ensures that immediate assistance can be provided to both the mother and the newborn. Allowing the head to deliver before checking for the cord (Choice A) may delay necessary interventions in case of complications. Instructing the mother to take short, quick breaths (Choice C) is not appropriate when the baby's head is already visible. Preparing for an emergency delivery and opening the obstetrics kit (Choice D) is important but should come after stopping the ambulance and assisting with the imminent birth.
You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?
- A. Lower the extremities and reassess the child
- B. Begin positive pressure ventilations and reassess the child
- C. Place a nasopharyngeal airway and increase the oxygen flow
- D. Listen to the lungs with a stethoscope for abnormal breath sounds
Correct Answer: A
Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.
The nurse is caring for a 3-day-old girl with Down syndrome whose mother had no prenatal care. What is the priority nursing diagnosis?
- A. Imbalanced nutrition, less than body requirements related to the effects of hypotonia
- B. Deficient knowledge related to the presence of a genetic disorder
- C. Delayed growth and development related to a cognitive impairment
- D. Impaired physical mobility related to poor muscle tone
Correct Answer: A
Rationale: The priority nursing diagnosis for a 3-day-old girl with Down syndrome, whose mother had no prenatal care, is imbalanced nutrition, less than body requirements related to the effects of hypotonia. Newborns with Down syndrome often experience feeding difficulties due to hypotonia, which can lead to inadequate nutrition intake. Option B is incorrect because at this age, the infant is not capable of having knowledge deficits related to a genetic disorder. Option C is incorrect as delayed growth and development are not the immediate priority in this scenario. Option D is incorrect as impaired physical mobility is not typically a priority concern for a newborn with Down syndrome.
What should the nurse include in the preoperative teaching for a 4-year-old child scheduled for a myringotomy?
- A. Explain the procedure in simple terms
- B. Encourage fluid intake
- C. Allow the child to play with medical equipment
- D. Use play therapy to prepare the child
Correct Answer: A
Rationale: For a 4-year-old child scheduled for a myringotomy, explaining the procedure in simple terms is essential in helping the child understand what will happen during the surgery and reducing anxiety. Encouraging fluid intake, allowing the child to play with medical equipment, and using play therapy are not directly related to preparing the child for the myringotomy procedure. Therefore, these options are incorrect and not as beneficial as explaining the procedure in simple terms.
