A total obstruction of the airway by aspirated material is manifested by:

A. Needle thoracentesis is typically performed in cases of pneumothorax or pleural effusion, not asthma exacerbation. The symptoms described do not indicate a pleural space issue that would require thoracentesis.

B. Emergency intubation may be necessary if the asthma exacerbation is severe and unresponsive to initial interventions such as bronchodilators, corticosteroids, and oxygen therapy. The patient's symptoms of severe dyspnea, accessory muscle use, and wheezing suggest respiratory distress, and intubation may be required to secure the airway and assist with ventilation.

C. Pleurodesis is a procedure used to treat recurrent pleural effusions, not asthma exacerbations. It involves the obliteration of the pleural space, which is not relevant to the current situation.

D. Chest tube insertion is typically performed for pneumothorax or other issues involving the pleural space, not for asthma exacerbation. The described symptoms do not suggest the need for a chest tube.

A. Intention tremors are typically associated with neurological conditions, such as Parkinson's disease, rather than Addison's disease.

B. Hirsutism, or excessive hair growth, is often seen in conditions involving excess androgen production, such as polycystic ovary syndrome (PCOS), but not typically in Addison's disease.

C. Purple striations, or stretch marks, are commonly seen in Cushing's syndrome due to excess cortisol production, not Addison's disease.

D. Hyperpigmentation is a hallmark symptom of Addison's disease. It occurs due to increased production of melanocyte-stimulating hormone (MSH), which is a byproduct of the overproduction of adrenocorticotropic hormone (ACTH) in response to adrenal insufficiency.
