Chapter 29 Introduction to the Autonomic Nervous System

Increased heart rate occurs with

beta-1 receptor stimulation

Nicotinic receptors would be found in which location?

Adrenal medulla

causes sodium and water retention and potassium excretion

Aldosterone

A client in distress has been given dobutamine, a medication intended to increase myocardial activity and heart rate. This medication likely stimulates what adrenergic receptor?

Beta-1

In which areas are nicotinic receptors located?

Nicotinic receptors are located in the CNS, the adrenal medulla, the autonomic ganglia, and the neuromuscular junction.

The physiology instructor explains to the nursing students that beta-2 stimulation leads to:

Vasodilation of blood vessels

Vasoconstriction and increased peripheral vascular resistance occurs with

alpha-1 receptor stimulation

Overstimulation of effector sites and moderate insulin release occurs with

alpha-2 stimulation

Norepinephrine is made by nerve cells using which substance?

by the nerve cells using tyrosine, which is obtained in the diet.

The nurse is caring for a client who is known to have deficient levels of dopamine because of a dietary lack of tyrosine. The nurse should expect to assess for evidence of:

decreased adrenergic response.

Pupil constriction is among the effect of parasympathetic stimulation of

muscarinic cholinergic receptors

suppresses the immune and inflammatory reactions to preserve energy during the fight or flight response

the release of adrenal hormones, including cortisol
