Autonomic Nervous System Flashcards
The patient experienced generalized weakness called myasthenia gravis (MG), which started in the afternoon and continued until the evening. If the patient does not take any drugs and the body continues to feel weak, the patient can stop breathing. What reversible indirect-acting drug could we use for the symptoms of MG if the patient has an episode?
Neostigmine and Pyridostigmine
What antidote could we use for tissue necrosis, extravasation of norepinephrine and dopamine?
Phentolamine Mesylate (Regitine)
Why do we need to assess the patient’s CBG?
The sympathetic nervous system will affect digestion, meaning that the glucose level of the patient may increase or decrease.
What indication/clue makes it easier for us to recognize the alpha blockers?
Alpha-blocker drugs end up with zosin
A sudden dizziness makes the blood pressure drop and the heart rate increase from lying down to sitting up, then sitting up to standing up is called ___________.
Orthostatic Hypotension
What indication/clue makes it easier for us to recognize beta blockers?
Beta-blocker drugs end with olol.
Timolol is an adrenergic antagonist used for the ____________, specifically for patients who have glaucoma to decrease the intraocular pressure.
Eyes
Nanz is the nurse tasked with taking the patient’s vital signs. Everything is normal except for the patient’s blood pressure of 140/100. The doctor instructs the patient to take prazosin orally. When does the peak of prazosin medication occur?
2-4 hours
Why does fatigue in the nursing process belong to the diagnosis for prazosin?
This is because blood flow is slowed down due to vasodilation.
Taking an adrenergic antagonist will lower the heart rate of the patient. As a nurse, what should you do if the patient’s heart rate is below 60? Do you think it is best to take the medication or withhold it?
It’s best to withdraw (keep it first) the medication and talk to the physician because if we make the patient drink the medication, his heart rate can even decrease.
Direct Acting or Indirect Acting
Acetylcholine is produced, but the drug cannot reach the receptor site. While the acetylcholinesterase attaches to it, the acetylcholine will not degrade its value and can stay inside and outside the receptor site.
Indirect Acting
Direct Acting or Indirect Acting
Acetylcholine is synthesized, produced, and released by the presynaptic nerve terminal. Even if the nerve terminal does not release acetylcholine, the drug will act as a substitute for the acetylcholine and will reach the receptor sites.
Direct Acting
What nursing intervention can be used if the patient has tissue necrosis as a result of an adrenergic agonist side effect?
If the patient is starting to have tissue necrosis, it would be best if we just moved the IV to another area so that the tissue necrosis that is not yet severe will heal quickly
It is not used for medical purposes and has no benefits, but it has become well-known for its military use as nerve gas that causes paralysis and death. The only clinical use for this is echothiophate.
Indirect Acting Irreversible
The adverse reaction is called “dumbbels.” What does the first initial B stand for and what does it mean?
Bronchorrhea means a runny nose.
