Which of the following is NOT an effect of catecholamine administration?

Catecholamines, such as epinephrine and norepinephrine, are hormones produced by the adrenal glands that play a crucial role in the body's response to stress. They are known for their stimulating effects on heart rate and cardiac contractility, as well as their impact on metabolic processes.

When catecholamines are administered, one of their primary effects is the increase in heart rate (tachycardia), achieved by stimulating the beta-1 adrenergic receptors in the heart. This leads to heightened cardiac output, which is beneficial in situations requiring a quick response from the cardiovascular system.

Additionally, catecholamines enhance the force of heart contractions (inotropic effect), which further increases cardiac output. This is particularly important during times of stress or emergency, where rapid blood circulation is vital.

Furthermore, catecholamines are known to elevate blood glucose levels by promoting gluconeogenesis and glycogenolysis in the liver. This ensures that sufficient energy is available to the body during stressful situations.

In contrast, the administration of catecholamines does not lead to decreased blood pressure; rather, it typically results in increased blood pressure due to vasoconstriction of blood vessels and the stimulation of heart rate and contractility. Therefore, stating that decreased blood pressure is
