Correct Answer: C

Rationale: When a child is unable to swallow a tablet, the appropriate response is to consider if a liquid form of the medication is available. This is a safer and more effective alternative than forcing the child to swallow or chew the tablet. Contacting the pharmacist for a prescription change can provide a suitable solution that ensures the child receives the medication in a more manageable form.

Correct Answer: C

Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis.

Correct Answer: A

Rationale: In a child with a history of iron-deficiency anemia presenting with symptoms of fatigue, pallor, and shortness of breath, the priority action for the nurse is to administer iron supplements as prescribed. Iron supplementation is essential to treat iron-deficiency anemia and improve the child's symptoms promptly.

Correct Answer: B

Rationale: Notifying the healthcare provider is crucial in this situation because the passage of a brown stool may indicate the resolution of intussusception. It is important to keep the healthcare provider informed about any changes in the infant's condition to ensure appropriate care and management.

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.
