Which signs are typically associated with hypokalemia in animals?

Hypokalemia, or low potassium levels in the blood, presents with specific clinical signs that reflect the muscle and nerve dysfunction resulting from this electrolyte imbalance. The correct choice highlights several of these symptoms that are particularly representative of hypokalemia in animals, especially in cats.

Weakness is a common sign since potassium plays a crucial role in muscle function. With low potassium levels, muscle fibers may not function properly, leading to generalized weakness. CNS depression can occur as potassium is vital for proper neuronal function; insufficient levels can impact the central nervous system, resulting in lethargy or decreased responsiveness.

Ventroflexion of the neck is particularly notable in cats with hypokalemia. This characteristic posture arises due to weakness of the neck muscles, which is directly related to potassium deficiency. This sign often stands out as it is quite specific to this condition, especially in feline patients.

Understanding these signs allows veterinarians and pet owners to recognize the potential for hypokalemia and seek timely treatment, which is crucial for reversing its effects and restoring normal physiological function.
