Which of the following are common manifestations of heart failure in infants? (SELECT ALL THAT APPLY)
Cool extremities and decreased urine output
Bradycardia and hypotension
Increased appetite and excessive weight gain
Poor feeding and weight gain
Tachypnea and respiratory distress
Correct Answer : A,D,E
A. Decreased cardiac output in heart failure can lead to poor perfusion of the extremities, resulting in cool skin and decreased urine output due to reduced renal perfusion and impaired kidney function.
D. Poor feeding is often observed due to increased respiratory effort, tachypnea, and fatigue associated with heart failure. Additionally, infants may exhibit failure to thrive or inadequate weight gain despite increased caloric intake due to metabolic demands and inefficient utilization of nutrients.
E. Tachypnea and respiratory distress occur due to pulmonary congestion and increased respiratory effort in response to heart failure. Infants may exhibit signs such as nasal flaring, grunting, retractions, and cyanosis.
B. Bradycardia and hypotension are not typical manifestations of heart failure in infants. Instead, infants with heart failure often present with tachycardia (rapid heart rate) as a compensatory mechanism to maintain cardiac output. Hypotension may occur in severe cases but is not a common finding.
C. Increased appetite and excessive weight gain are not typical manifestations of heart failure in infants. Infants with heart failure often experience poor feeding and failure to thrive due to inadequate cardiac output and oxygen delivery to meet metabolic demands.

Correct Answer is C
Explanation
C. Muscle weakness and lack of coordination contribute to difficulties with balance and coordination, leading to frequent falls and clumsiness in children with DMD.
A. DMD typically presents with symptoms such as difficulty climbing stairs, a waddling gait, and calf muscle hypertrophy, rather than atrophy.
B. Delayed fine-motor development is not a typical manifestation of Duchenne muscular dystrophy. DMD primarily affects muscle strength and function rather than fine motor skills.
D. Ambulating by holding onto furniture is not typical in Duchenne muscular dystrophy. As the disease progresses, children with DMD typically experience difficulty walking and may eventually require the use of assistive devices such as wheelchairs or orthoses for mobility.
Correct Answer is A
Explanation
A. Wheezing, which is a high-pitched whistling sound heard during expiration, is a common symptom of asthma. It occurs due to narrowed airways and airflow obstruction, often in response to triggers such as allergens, respiratory infections, or exercise.
B. Low-grade fever in the afternoon is not typically associated with asthma. Fever is more commonly seen in response to infections, such as respiratory infections, which can exacerbate asthma symptoms but is not a direct manifestation of asthma itself.
C. Without the complete statement, it is difficult to assess its relevance to asthma symptoms. However, an abrupt onset of symptoms, such as sudden shortness of breath or chest tightness, may occur during an asthma attack or exacerbation.
D. Sharp pleuritic pain is not a typical finding in asthma. Pleuritic pain, which is sharp and worsened by breathing, is more commonly associated with conditions affecting the pleura, such as pneumonia or pleurisy.
