The classic manifestations associated with Parkinson's disease are tremor, rigidity, bradykinesia, and postural instability. The nurse understands that a finding related to postural instability includes which of the following?

A. A client with myasthenia gravis who has bilateral ptosis and a positive edrophonium test is likely experiencing a myasthenic crisis, which is a life-threatening condition that requires immediate attention. This client would be the priority because they may require rapid intervention to maintain airway and breathing.
B. Bell's palsy is characterized by sudden onset of facial paralysis due to inflammation of the facial nerve. While Bell's palsy can be distressing for the client, it does not typically require urgent intervention unless there are complications such as corneal abrasion due to inability to close the eye.
C. Parkinson's disease is a chronic neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability. While this client requires ongoing assessment and care, the symptoms described do not typically indicate an acute or urgent need for intervention.
D. A client with multiple sclerosis who has bladder flaccidity and is retaining urine needs assessment and intervention to prevent complications such as urinary tract infections or renal damage. However, this is not as immediately life-threatening as a myasthenic crisis.

A. This symptom is consistent with orthopnea, which is common in left-sided heart failure rather than right-sided heart failure. In orthopnea, patients experience shortness of breath when lying flat because fluid accumulates in the lungs due to impaired left ventricular function.
B. Pink-tinged or blood-tinged sputum, known as hemoptysis, can occur in left-sided heart failure due to pulmonary congestion and elevated pressures in the pulmonary circulation. This symptom is not typically associated with right-sided heart failure.
C. This finding suggests pulmonary congestion, which is more indicative of left-sided heart failure. In left- sided heart failure, fluid backs up into the lungs, leading to crackles or rales on auscultation.
D. This statement is consistent with right-sided heart failure. In right-sided heart failure, the right ventricle fails to effectively pump blood into the pulmonary circulation, causing fluid to back up into the venous system. This can lead to peripheral edema (such as in the legs and abdomen) and abdominal distension due to ascites (fluid accumulation in the peritoneal cavity).
