Correct Answer: C

Rationale: The correct answer is C: 'Dry, hacking cough.' A dry, hacking cough is a classic manifestation of pertussis. Pertussis typically presents with symptoms of an upper respiratory tract infection, starting with a persistent, severe, and uncontrollable cough that can worsen at night. This cough is often followed by a high-pitched 'whoop' sound as the patient tries to catch their breath, hence the term 'whooping cough.' In contrast, options A, B, and D are not typically associated with pertussis. Inflamed throat with exudate may suggest a bacterial throat infection like streptococcal pharyngitis, purulent eye drainage is more indicative of a bacterial conjunctivitis, and Koplik spots on the buccal mucosa are specific to measles. Therefore, recognizing the dry, hacking cough as a manifestation of pertussis is crucial for early identification and appropriate management of the disease.

Encouraging independence and allowing children to explore and create their play scenarios can enhance playfulness and creativity.

Correct Answer: B

Rationale: The correct answer is to give the medication with orange juice. Orange juice helps increase the absorption of iron from ferrous sulfate. This acidic environment aids in the absorption of iron, making it a suitable choice for administration. Mixing the medication with milk or an antacid may decrease iron absorption, and giving it with meals may not optimize its absorption as effectively as with orange juice.
