What are the earliest recognizable clinical manifestations of cystic fibrosis (CF)?
Meconium ileus.
Foul-smelling, frothy, greasy stools.
History of poor intestinal absorption.
Recurrent pneumonia and lung infections.
The Correct Answer is A
The correct answer is choice A. Meconium ileus.
Choice A rationale:
Meconium ileus. This is the earliest recognizable clinical manifestation of cystic fibrosis (CF). Meconium ileus refers to the blockage of the small intestine by thick, sticky meconium, the earliest stool of a newborn. It occurs in the first 24-48 hours of life and can be a sign of underlying cystic fibrosis.
Choice B rationale:
Foul-smelling, frothy, greasy stools. Foul-smelling, frothy, greasy stools are characteristic of malabsorption, which can occur in cystic fibrosis. However, this manifestation typically appears after meconium ileus and is not the earliest recognizable clinical sign.
Choice C rationale:
History of poor intestinal absorption. While poor intestinal absorption is a common consequence of cystic fibrosis, it is not one of the earliest recognizable clinical manifestations. Meconium ileus takes precedence as the primary early sign.
Choice D rationale:
Recurrent pneumonia and lung infections. Recurrent pneumonia and lung infections are common in later stages of cystic fibrosis due to the buildup of thick mucus in the respiratory tract. However, they are not among the earliest recognizable clinical manifestations of the disease. Meconium ileus is the earliest indicator in this context.

Correct Answer is C
Explanation
The correct answer is choice C: Administering penicillin.
Choice A rationale:
Imposing strict bed rest for 4 to 6 weeks. This choice is not the most appropriate therapeutic management for rheumatic fever. While rest is important during the acute phase, strict bed rest for 4 to 6 weeks is excessive and could lead to physical deconditioning and psychological distress for the child.
Choice B rationale:
Administering corticosteroids if chorea develops. This choice is relevant to the management of rheumatic fever but is not the primary treatment. Chorea is a movement disorder that can occur as a complication of rheumatic fever. Corticosteroids may be used to manage chorea symptoms, but they are not the mainstay of treatment for rheumatic fever itself.
Choice C rationale:
Administering penicillin. This is the correct choice. Penicillin is the mainstay of treatment for rheumatic fever. It helps eradicate the group A streptococcal infection that triggers the inflammatory response leading to rheumatic fever. Penicillin is essential to prevent further complications such as rheumatic heart disease.
Choice D rationale:
Avoiding salicylates (aspirin). This choice is also relevant to the management of rheumatic fever. Salicylates, including aspirin, are used to relieve symptoms and reduce inflammation. However, in children with acute rheumatic fever, salicylates are contraindicated due to the risk of developing Reye's syndrome, a serious condition that affects the brain and liver.
Correct Answer is ["2.6"]
Explanation
Step 1: Calculate the total mg per dose. 325 mg × 2 tablets = 650 mg
Step 2: Calculate the number of doses in 24 hours. 24 hours ÷ 6 hours = 4 doses
Step 3: Calculate the total mg in 24 hours. 650 mg × 4 doses = 2600 mg
Step 4: Convert mg to grams. 2600 mg ÷ 1000 = 2.6
Answer: 2.6
