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.

Correct Answer: A

Rationale: Weighing the diapers is the most appropriate method to assess urine output in infants. Diapers will absorb and retain urine, providing a measurable indicator of urine output without invasive procedures. This method is non-invasive, simple, and convenient for monitoring urine output, especially in infants who may not be able to use other urine output measurement techniques. Inserting a Foley catheter is invasive and not indicated for routine urine output monitoring in infants. Comparing intake with output does not directly measure urine output. Measuring the amount of water added to formula does not provide an accurate assessment of urine output.

Correct Answer: A

Rationale: Jaundice seen within 24 hours of life is considered more serious in children as it can indicate pathological causes such as hemolytic disease or sepsis, which require prompt evaluation and management to prevent complications. Jaundice appearing within 24 hours of life is concerning due to the higher likelihood of severe conditions, while jaundice seen at the palms and soles is more likely due to physiological causes such as breast milk jaundice. Jaundice appearing after 24 hours or after 14 days of life may still require evaluation but is less urgent compared to jaundice within the first 24 hours.

Correct Answer: B

Rationale: Evaluation is the correct stage in the nursing process to determine if the patient has achieved the expected outcomes. During the evaluation stage, the healthcare provider assesses the effectiveness of the care plan and decides on any necessary adjustments to reach the desired goals. Choice A, Implementation, is incorrect because this stage involves putting the care plan into action. Choice C, Assessment, is incorrect as it is the stage where data about the patient's health status is gathered. Choice D, Diagnosis, is also incorrect as it is the stage where the healthcare provider identifies the patient's health problems based on the assessment data.

Correct Answer: C

Rationale: During the 'Provide practical treatment' phase, the nurse is expected to give appropriate treatment to address the patient's needs. This involves implementing the necessary medical interventions or care based on the assessment findings and treatment plan. While greeting the mother, assessing for danger signs, and checking vital signs are important aspects of patient care, the focal point during this phase is to administer the specific treatment required to manage the patient's condition effectively.
