What is a common, serious complication of rheumatic fever?
Pulmonary hypertension.
Cardiac valve damage.
Seizures.
Cardiac arrhythmias.
The Correct Answer is B
The correct answer is choice B. Cardiac valve damage.
Choice A rationale:
Pulmonary hypertension is not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain, and pulmonary hypertension is not a typical manifestation of this condition.
Choice B rationale:
Cardiac valve damage is a common and serious complication of rheumatic fever. Rheumatic fever is caused by an autoimmune reaction to untreated streptococcal infections, particularly Streptococcus pyogenes. The immune response targets not only the streptococcal bacteria but also the body's own tissues, especially heart valves. This can lead to inflammation of the heart valves, a condition known as rheumatic heart disease. Over time, repeated bouts of rheumatic fever can result in significant damage to the heart valves, leading to valve insufficiency or stenosis. This can ultimately cause heart failure and other cardiovascular complications.
Choice C rationale:
Seizures are not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart and other body systems, but it does not typically lead to seizures.
Choice D rationale:
Cardiac arrhythmias are possible complications of rheumatic fever, but they are not as common or significant as cardiac valve damage. The inflammation and scarring caused by rheumatic fever can disrupt the electrical pathways of the heart, potentially leading to arrhythmias. However, the more prevalent and severe consequence of rheumatic fever is the damage to the heart valves.

Correct Answer is B
Explanation
The correct answer is choice B. First stage.
Choice A rationale:
There is no fourth stage of Lyme disease. Lyme disease typically progresses through three stages: early localized, early disseminated, and late disseminated. The symptoms mentioned in the question are more indicative of earlier stages of the disease.
Choice B rationale:
The child is likely exhibiting symptoms of the first stage of Lyme disease, known as early localized Lyme disease. This stage is characterized by the appearance of small annular (circular) lesions known as erythema migrans. These lesions are often red and have a clear center, resembling a "bull's-eye" pattern. This stage occurs within days to weeks after a tick bite and is usually accompanied by flu-like symptoms.
Choice C rationale:
There is no third stage of Lyme disease. The third stage is considered the late disseminated stage, which occurs months to years after the initial infection. It typically involves more severe symptoms, such as arthritis, neurological issues, and cardiac abnormalities.
Choice D rationale:
There is no second stage of Lyme disease. The second stage is the early disseminated stage, which occurs weeks to a few months after the tick bite. It involves the spread of the bacteria to other parts of the body, leading to symptoms such as multiple erythema migrans lesions, flu-like symptoms, fatigue, and muscle and joint pain.
Correct Answer is ["954.5"]
Explanation
Step 1 is converting the child's weight from pounds to kilograms. (42 lb ÷ 2.2) = 19.09090909 kg
Step 2 is calculating the maximum daily dosage using the upper limit of the dosage range (50 mg/kg/day). 19.09090909 kg × 50 mg/kg/day = 954.5454545 mg/day
Step 3 is rounding the result to the nearest tenth. The answer is 954.5
