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
