A patient with asthma is admitted with severe dyspnea and is unable to speak. The nurse finds that the patient looks drowsy and confused. Which other finding would the nurse expect?

A. Tachypnea, or rapid breathing, is a common finding in pneumonia due to hypoxia and the body's attempt to compensate for impaired gas exchange in the lungs. It is one of the hallmark signs of pneumonia.
B. Bradycardia is uncommon in pneumonia. Tachycardia (increased heart rate) is more frequently observed as the body compensates for the infection and reduced oxygenation.
C. Hypothermia is not typically associated with pneumonia; more commonly, fever (hyperthermia) is present as a sign of infection.
D. A pulse deficit is a sign of a heart condition, such as atrial fibrillation, not typically related to pneumonia.

A. Pheochromocytoma is a tumor of the adrenal glands that can cause excessive production of catecholamines (such as norepinephrine and epinephrine), leading to a hypertensive crisis. This condition can cause severe hypertension, headaches, palpitations, and sweating.
B. Adrenal insufficiency is typically associated with low blood pressure, not hypertension. It is characterized by symptoms like weakness, fatigue, and hypotension, which are not linked to hypertensive crises.
C. Hypothyroidism is associated with low blood pressure and bradycardia, not an increased risk of hypertensive crisis. It typically leads to symptoms like weight gain, fatigue, and cold intolerance.
D. Diabetes insipidus is a condition that leads to excessive urination and thirst due to a lack of antidiuretic hormone, but it does not directly lead to a hypertensive crisis. It is primarily concerned with electrolyte imbalance and dehydration.
