A client with a cold sore on the lip has been diagnosed with herpes simplex virus. Which neurological disorder may the client be at risk for in the future?

Myasthenia gravis

Multiple sclerosis

Guillain-Barre syndrome

Bell's palsy

Answer and Explanation

The Correct Answer is D

A.   Myasthenia gravis is an autoimmune disorder characterized by weakness and rapid fatigue of voluntary muscles due to impaired communication between nerves and muscles. It is not directly related to HSV infection.
B.   Multiple sclerosis (MS) is a chronic autoimmune disorder that affects the central nervous system, leading to demyelination of nerve fibers. While the exact cause of MS is not completely understood, it is thought to involve a combination of genetic and environmental factors. HSV is not directly associated with the development of MS.
C.   Guillain-Barre syndrome (GBS) is an acute, autoimmune condition that affects the peripheral nervous system, leading to progressive muscle weakness and paralysis. GBS is often preceded by an infection, and while it is most commonly associated with infections like Campylobacter jejuni, other infections, including HSV, have also been implicated as potential triggers for GBS.
D.   Bell's palsy is a condition characterized by sudden, unilateral facial paralysis or weakness due to inflammation of the facial nerve (cranial nerve VII). HSV has been identified as a potential cause of Bell's palsy, as the virus can lead to inflammation of the facial nerve.

Correct Answer is A

Explanation

A. Pursed-lip breathing is an effective technique for managing COPD symptoms, particularly tachypnea and dyspnea. It helps to keep the airways open by creating back pressure that prevents the collapse of bronchioles and reduces air-trapping. This technique improves ventilation and helps with the expiration of trapped air, making it a valuable intervention for COPD patients.
B. The Trendelenburg position involves lying flat on the back with the legs elevated higher than the head. This position is not suitable for managing COPD symptoms and can actually worsen breathing difficulties by increasing abdominal pressure on the diaphragm.
C. High-frequency chest wall oscillation (HFCWO) vests are used to help with airway clearance in conditions like cystic fibrosis or chronic bronchitis by loosening mucus. While beneficial for mucus management, they do not specifically address bronchiolar collapse or air-trapping associated with COPD.
D. Measuring the FEV1/FVC ratio is a diagnostic tool used to assess the severity of airflow obstruction in COPD. While this information is important for diagnosis and treatment planning, it is not an immediate intervention to manage symptoms such as tachypnea and dyspnea.

A. Hypernatremia B. Fluid volume overload C. Hypokalemia D. Hypoglycemia

Correct Answer is D

Explanation

A. Hypernatremia (elevated sodium levels) is not a common sign of Addisonian crisis. In Addisonian crisis, the lack of aldosterone leads to sodium loss, which often results in hyponatremia (low sodium levels) rather than hypernatremia. The patient might also experience dehydration and electrolyte imbalances, but hypernatremia is not typical in this scenario.
B. Fluid volume overload is not characteristic of Addisonian crisis. Instead, Addisonian crisis often leads to fluid volume deficit due to the loss of aldosterone, which impairs sodium and water retention. This can result in dehydration and low blood volume rather than fluid overload.
C. Hypokalemia (low potassium levels) is not typically associated with Addisonian crisis. In fact, the lack of aldosterone in Addisonian crisis leads to potassium retention, resulting in hyperkalemia (elevated potassium levels). Therefore, monitoring for hypokalemia is not relevant in the context of Addisonian crisis following a bilateral adrenalectomy.
D. Hypoglycemia (low blood glucose levels) is a key sign of Addisonian crisis. Cortisol plays a crucial role in glucose metabolism and maintaining blood glucose levels. With the loss of cortisol production after a bilateral adrenalectomy, patients may experience hypoglycemia, which can be a critical indicator of Addisonian crisis.
