Correct Answer: A

Rationale: In a child presenting with ear pain and fever, asking if the child has had a runny nose is crucial in assessing for possible ear infection causes. Respiratory infections can lead to secondary ear infections, so exploring symptoms related to upper respiratory tract infections, like a runny nose, can help in the evaluation and management of the child's condition.

Correct Answer: A

Rationale: The appropriate response for the caregiver is to address the parents' concerns by suggesting scheduling a hearing test and potentially referring the child to a speech therapist if necessary. This proactive approach can help evaluate and support the child's hearing and speech development effectively.

Correct Answer: D

Rationale: Administering the HPV vaccine helps establish immunity before potential exposure to the virus, reducing the risk of HPV infection and subsequent development of cervical cancer. It is recommended to vaccinate adolescents before they become sexually active for maximum effectiveness.

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.

Correct Answer: A

Rationale: In a postoperative neonatal setting, an increase in respiratory rate (RR) and heart rate (HR) in an infant could indicate pain or distress. It is crucial for the nurse to notify the healthcare provider promptly to assess the infant's condition and provide appropriate interventions. Prompt communication with the healthcare provider ensures timely evaluation and management of the infant's discomfort or distress, promoting optimal postoperative recovery and comfort.
