RECEPTORS
Beta-1 receptors primarily regulate _____ function
What is the heart?
Positive chronotropic effect:
What is an increase in heart rate?
When your blood pressure falls, your kidneys release ________ into your bloodstream.
What is renin?
When on this medication, the nurse is monitoring the PT/INR levels in the blood.
What is warfarin?
This medication can be taken along with a statin medication to help with absorption of cholesterol.
What is cholestyramine?
Beta-2 receptors primarily regulate _____ function
What is lung?
Mydriasis means:
What is pupillary dilation?
________ is a peptide hormone that plays a crucial role in regulating blood pressure and fluid balance in the body. It causes vasoconstriction, which narrows blood vessels and increases blood pressure
What is angiotensin?
When on this medication, the nurse is monitoring the aPTT levels in the blood.
What is heparin?
This medication is administered rapidly to quickly restore normal heart rhythm during episodes of supraventricular tachycardia (SVT) by temporarily blocking electrical signals in the heart. There may be a temporary period of asystole.
What is adenosine?
Adrenergic drugs, (such as Alpha-1's), with effects that are similar to or mimic the effects of the SNS neurotransmitters norepinephrine, epinephrine, and dopamine. These are known as:
What are catecholamines?
First-dose phenomenon:
What is a severe and sudden drop in blood pressure after the administration of the first dose of an alpha-adrenergic blocker?
_________ block the action of angiotensin II, a hormone that normally causes blood vessels to constrict and increases blood pressure.
What are Angiotensin Receptor Blockers (or ARBs)?
The range for aPTT is __________. When at a therapeutic level how is this determined ____________
What 30 to 40 and 1.5 to 2x greater than normal?
It is one of the preferred antihypertensive agents for pregnant women, helping to manage high blood pressure during pregnancy and reduce the risk of complications for both mother and baby.
What is methyldopa?
By blocking stimulation of alpha1 receptors, these drugs reduce smooth muscle contraction of the bladder neck and the prostatic portion of the urethra
What are tamsulosin, doxazosin, prazosin?
Orthostatic hypotension:
What is a sudden drop in blood pressure when a person stands up. Also referred to as postural hypotension or orthostasis?
_________ activate the RAAS primarily by reducing blood volume, with effects varying by diuretic class and influencing renin and aldosterone levels
What are diuretics?
The range for PT is ________ and INR is _______
What is 11.5 to 12 and 1 - 3
This medication is a non-selective α‑adrenergic receptor antagonist that causes blood vessels to dilate, increasing blood flow. It can be used to counteract severe peripheral vasoconstriction from extravasation of vasopressor infusions.
What is phentolamine?
This medication is a direct-acting cholinergic agonist. It is used in the treatment of acute postoperative and postpartum nonobstructive urinary retention and for the management of urinary retention associated with neurogenic atony of the bladder.
What is Bethanechol?
Preload is ________ while afterload is ________.
What is the ventricular filling pressure before contraction and afterload is the resistance the heart must overcome to eject blood
Your adrenal glands produce this hormone, __________, to manage sodium and potassium levels in your blood.
What is aldosterone?
Clot busters, also known as thrombolytic or fibrinolytic drugs, are powerful medications designed to dissolve harmful blood clots that block blood flow to vital organs. Name one:
What is alteplase, reteplase?
____________is a naturally occurring hormone primarily produced by specialized cells in the kidneys that plays a key role in regulating red blood cell production
What is erythropoietin?
This medication when used at low dosages, can dilate blood vessels in the brain, heart, kidneys, and mesentery, which increases blood flow to these areas (dopaminergic receptor activity).
What is dopamine?
Severe muscle weakness and respiratory paralysis due to excessive acetylcholine; often seen in patients with myasthenia gravis as an adverse effect of drugs used to treat the disorder.
What is a cholinergic crisis?
The ___________ is a critical brain structure that controls many vital physiological processes including hormone release, temperature regulation, hunger and thirst, sleep cycles, emotions, and the autonomic nervous system.
What is the hypothalamus?
When a patient presents to the ED with a potential PE (pulmonary embolism), they are often started on a heparin drip AND warfarin. Is this safe? And explain why?
What is yes. Warfarin will take 2 to 3 days to become therapeutic and heparin will be stopped.
This medication is used in severe hypertension crisis in the ICU. This medication can lead to cyanide toxicity due to its metabolism, which releases cyanide ions that can cause severe health complications
What is Nitroprusside?
