🧠 Answer: Tremors, Postural instability, Rigidity, and Akinesia are correct because these symptoms form the classic motor-movement pattern of Parkinson’s disease caused by dopamine depletion in the basal ganglia.

🧠 Tremors are correct because Parkinson’s disease produces a characteristic “resting tremor,” often described as a pill-rolling motion, caused by basal ganglia dysfunction.

🧠 This tremor decreases with purposeful movement and worsens at rest, making it one of the earliest and most recognizable symptoms.

🧠 Postural instability is correct because dopamine deficiency impairs the body’s automatic balance responses.

🧠 Clients have difficulty maintaining upright posture, experience frequent falls, and struggle with equilibrium when walking or turning.

🧠 Rigidity is correct because Parkinson’s causes stiff, inflexible muscles due to abnormal neural signaling.

🧠 This leads to cogwheel rigidity, where the limbs move in a ratcheted pattern when the nurse performs passive range of motion.

🧠 Akinesia is correct because this refers to the loss or slowing of voluntary movements, making it difficult for clients to initiate activities like walking, speaking, or swallowing.

🧠 This is one of the most disabling features and contributes to shuffling gait and mask-like facial expression.

🧠 Dry mouth is incorrect because while dry mouth can occur due to medications used for Parkinson’s (like anticholinergics), it is not a primary symptom of the disease itself.
