Which of the following assessment findings indicates an emergency and the need for immediate action on the part of the nurse?

A. Furosemide is a diuretic that is used to reduce fluid overload and manage conditions like heart failure or kidney disease. It is not indicated in anaphylaxis.
B. Methylprednisolone is a corticosteroid used for its anti-inflammatory properties and can be used in anaphylaxis to reduce inflammation and prevent delayed reactions. However, it is not the first-line treatment in acute anaphylactic shock.
C. Epinephrine is the first-line treatment for anaphylactic shock. It works by rapidly reversing the effects of anaphylaxis, such as bronchoconstriction, vasodilation, and edema, by stimulating alpha and beta receptors. Epinephrine should be administered as soon as anaphylaxis is suspected to stabilize the patient’s condition.
D. Dobutamine is a medication used to manage shock by increasing cardiac output, but it is not used in the management of anaphylactic shock. The priority is epinephrine to reverse the anaphylactic response.

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.
