The nurse notes that which disorder places the patient at greatest risk for hypertensive crisis?

Pheochromocytoma

Adrenal insufficiency

Hypothyroidism

Diabetes insipidus

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

A. The optimal position for a thoracentesis is sitting upright with the patient leaning forward slightly, with elbows resting on an over-bed table to help expose the pleural space for access. This position allows gravity to pull the lungs downward and facilitates easier access to the pleural cavity.
B. Sitting in bed with knees slightly flexed and feet flexed is not the best position for thoracentesis. This position might limit the ability to properly expose the thoracic cavity for the procedure.
C. Lying flat in the fetal position on the unaffected side would not allow for effective drainage or access to the pleural space and is not ideal for thoracentesis.
D. Lying flat on the unaffected side with knees slightly flexed is not ideal because it does not provide optimal positioning for the procedure. The upright position is preferred for thoracentesis to facilitate easy access to the pleural space.
