1. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperpneic. Which action should the nurse implement first?

• A. Administer morphine sulfate.
• B. Start IV fluids.
• C. Place the infant in a knee-chest position.
• D. Provide 100% oxygen by face mask.

Correct answer: C

Rationale: In a situation where an infant with tetralogy of Fallot is acutely cyanotic and hyperpneic, the priority action should be to place the infant in a knee-chest position. This position helps increase systemic vascular resistance, improving pulmonary blood flow and subsequently ameliorating the cyanosis and hyperpnea. It is a non-invasive and effective intervention that can be promptly implemented by the nurse to address the immediate respiratory distress. Administering morphine sulfate (Choice A) is not the priority in this case as it may cause further respiratory depression. Starting IV fluids (Choice B) may not address the immediate cyanosis and hyperpnea. Providing 100% oxygen by face mask (Choice D) can help with oxygenation but may not be as effective as placing the infant in a knee-chest position to improve blood flow dynamics.

2. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

3. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?

• A. Laughs readily, turns from back to side.
• B. Has strong Moro and tonic neck reflexes.
• C. Keeps fists clenched, opens hands when grasping an object.
• D. Can lift head but not chest when lying on abdomen.

Correct answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.

4. When caring for a child with Kawasaki disease, which symptom is the most significant for making this diagnosis?

• A. Desquamation of the palms and soles.
• B. Cervical lymphadenopathy.
• C. Erythema of the hands and feet.
• D. Strawberry tongue.

Correct answer: C

Rationale: Erythema of the hands and feet is a key diagnostic criterion for Kawasaki disease. This, along with other symptoms like fever and strawberry tongue, helps in making the diagnosis. While desquamation of the palms and soles, cervical lymphadenopathy, and strawberry tongue are associated with Kawasaki disease, the presence of erythema of the hands and feet is particularly significant in diagnosing this condition.

5. A child with pertussis is receiving azithromycin (Zithromax Injection) IV. Which intervention is most important for the nurse to include in the child’s plan of care?

• A. Obtain vital signs to monitor for fluid overload
• B. Change IV site dressing every 3 days and as needed
• C. Monitor for signs of facial swelling or urticaria
• D. Assess for abdominal pain and vomiting

Correct answer: C

Rationale: Monitoring for signs of an allergic reaction, such as facial swelling or urticaria, is crucial when administering antibiotics like azithromycin. It is important to watch for these signs to promptly identify and manage any potential adverse reactions during the course of treatment.
