All are signs of congestive cardiac failure in infants except?
**Core Concept**
Congestive cardiac failure (CCF) in infants is a complex condition characterized by the heart's inability to pump enough blood to meet the body's needs, leading to fluid buildup in various organs and tissues. In infants, CCF can manifest differently than in adults, and it's essential to recognize the unique signs and symptoms of this condition.
**Why the Correct Answer is Right**
Infants with congestive cardiac failure often exhibit signs of poor perfusion, including **poor feeding**, **failure to thrive**, and **tachypnea** (rapid breathing). These symptoms are a result of the heart's inability to meet the body's oxygen and nutrient demands, leading to a compensatory increase in respiratory rate. In addition, infants with CCF may also exhibit signs of fluid overload, such as **edema** (swelling) in the legs, feet, and abdomen.
**Why Each Wrong Option is Incorrect**
* **Option A:** Tachycardia (rapid heart rate) is a common sign of congestive cardiac failure in infants, as the heart tries to compensate for its decreased pumping efficiency. However, it's not the only sign, and the question asks for an exception.
* **Option B:** Hepatomegaly (enlarged liver) is a sign of fluid overload in congestive cardiac failure, as the liver becomes congested with blood. This is a common finding in infants with CCF.
* **Option C:** This option is not provided.
**Clinical Pearl / High-Yield Fact**
In infants with congestive cardiac failure, it's essential to look for signs of poor perfusion, such as poor feeding and failure to thrive, in addition to the more obvious signs of fluid overload like edema.
**Correct Answer: A. Tachycardia is not an exception to signs of congestive cardiac failure in infants, as it is a common finding.**
