100
What gets converted into angiotensin II?
Angiotensin I
100
What do CCBs block?
Calcium ion channels
100
What is A1 referring to?
Alpha1-adrenergic
100
What is the generic name of Lopresor?
Metoprolol
100
What is an example of an ACE inhibitor (besides Accupril)?
Altace (ramipril)
200
What is the pathway that is effected by blocking the action of angiotensin II?
Renin-angiotensin pathway
200
What effect does blocking calcium ion channels have on the body? (list 3)
Limits muscular contraction, causes smooth muscle in arterioles to relax, lowers peripheral resistance, decreases BP
200
What body system is effected by adrenergic drugs?
Sympathetic nervous system (fight/flight)
200
What is the classification of beta-blockers (besides anti-hypertensives)?
Anti-anginals
200
What is the mechanism of action for ACE inhibitors?
Blocks the enzyme that converts angiotensin I to angiotensin II - vasodilation
300
What are at least 3 common side effects of using ARBs?
Cough, elevated potassium levels, low blood pressure, dizziness, headache, drowsiness, diarrhea, abnormal taste sensation (metallic or salty), rash
300
What are 3 nursing priorities to remember when taking care of a patient taking CCBs?
Assess ECG, HR, BP, lab values before therapy. Monitor vitals. Advise pt not to consume grapefruit juice.
300
What do A1-blockers do?
Cause vasodilation in peripheral vessels.
300
What effect do beta blockers have on the heart?
Decreases cardiac contractility
300
Where were ACE inhibitors first detected? In the _____ of ______ in the 1960s.
Venom of pit vipers.
400
What is an example of an ARB (besides the example I gave in my handout)?
What is an example of an ARB (besides the example I gave in my handout)?Atacand (candesartan), Teveten (eprosartan), Avapro/ Avalide (irbesartan), Cozaar (losartan), Micardis (telmisartan)
400
What teaching would you carry out to the pt?
Report dizziness/light-headedness, chest pain or other angina-like symptoms, rise slowly from prolonged periods of sitting or lying
400
What are 3 nursing priorities to look out for with a pt taking A1-blockers?
Assess BP (monitor for hypotension), monitor first dose, monitor CNS changes and urinary rentention
400
What are 3 nursing priorities for pts taking beta-blockers?
Monitor HR, BP & cardiac status. Educate client to report any abdominal pain, unusual bleeding, changes in color of urine or stool. Advise pts with diabetes to monitor blood glucose closely.
400
What does angiotensin-converting enzyme (ACE) do to the body?
Intense vasoconstriction of arterioles caused by angiotensin II - causing increased peripheral resistance and increased BP
500
What does the renin-angiotensin system control?
Blood pressure and fluid balance
500
Would you watch for edema in a pt taking CCBs? If so, what interventions would you specifically carry out?
Yes. I&O's, daily weights
500
What is the maximum recommended dose of A1-blockers? (specifically Cardura)
16mg/day
500
What is the maximum dose of a beta-blocker (specifically Lopresor)?
400mg/day
500
ACE inhibitors may cause potassium levels to increase in the blood. What is a dangerous value & why?>
5mmol/L is abnormal, but > 7mmol/L is really dangerous. May cause muscle fatigue, abnormal heart rhythms, nausea, paralysis.
