A client is admitted with the diagnosis of "left-sided embolic stroke". Which explanation best describes the most likely cause of the stroke?

Choice A reason: Hemothorax is not the correct explanation because it is a condition where blood accumulates in the pleural space, which is the area between the lungs and the chest wall. Hemothorax can cause low blood pressure, rapid breathing, and reduced breath sounds, but it does not cause tracheal deviation, which is a sign of increased pressure in the chest.

Choice B reason: Absorption atelectasis is not the correct explanation because it is a condition where the alveoli, which are the tiny air sacs in the lungs, collapse due to lack of oxygen. Absorption atelectasis can cause reduced breath sounds, but it does not cause low blood pressure, rapid breathing, or tracheal deviation, which are signs of a life-threatening emergency.

Choice C reason: Tension pneumothorax is the correct explanation because it is a condition where air leaks into the pleural space and creates a one-way valve that prevents the air from escaping. This causes the pressure in the chest to increase, which compresses the lung, the heart, and the great vessels. Tension pneumothorax can cause low blood pressure, rapid breathing, absent breath sounds, and tracheal deviation, which are signs of a medical emergency that requires immediate treatment.

Choice D reason: Hypovolemic shock is not the correct explanation because it is a condition where the body loses a large amount of blood or fluid, which reduces the blood volume and the blood pressure. Hypovolemic shock can cause low blood pressure and rapid breathing, but it does not cause absent breath sounds or tracheal deviation, which are signs of a chest injury.

Choice A reason: Hepatomegaly is not the expected finding because it is a condition where the liver is enlarged, which can be caused by various factors, such as infections, tumors, or cirrhosis. Hepatomegaly is not a common manifestation of systemic lupus erythematosus, which is an autoimmune disease that causes inflammation and damage to various organs and tissues in the body.

Choice B reason: Abdominal cramping pain is not the expected finding because it is a symptom that can be caused by various conditions, such as irritable bowel syndrome, appendicitis, or diverticulitis. Abdominal cramping pain is not a specific manifestation of systemic lupus erythematosus, although some clients may experience abdominal discomfort due to gastritis, pancreatitis, or peritonitis, which are possible complications of the disease.

Choice C reason: Whitish patches on the tongue are not the expected finding because they are a sign of oral candidiasis, which is a fungal infection that affects the mouth and throat. Oral candidiasis can be caused by various factors, such as weakened immune system, antibiotic use, or diabetes. Oral candidiasis is not a typical manifestation of systemic lupus erythematosus, although some clients may have oral ulcers, which are painful sores that appear on the lips, gums, or tongue.

Choice D reason: Arthritis with papular rash is the expected finding because it is a characteristic manifestation of systemic lupus erythematosus, which affects the joints and the skin. Arthritis is a condition where the joints are inflamed, causing pain, stiffness, and swelling. Arthritis can affect any joint in the body, but it is more common in the hands, wrists, and knees. Papular rash is a type of skin rash that consists of small, raised bumps that are red or purple. Papular rash can appear on any part of the body, but it is more common on the face, especially on the cheeks and the bridge of the nose. Papular rash is also known as malar rash or butterfly rash, because of its shape and location.
