Hypertension DAY 2 Flashcards

1
Q

What are the 4 general principles of hypertension medications?

A
  1. ALL can cause hypotension
  2. ALL increase risk for orthostasis/orthostatic hypotension
    - ESPECIALLY in drugs that: DILATE vessels & Decrease fluid volume***!!!
    so you’ll have more of a problem with my Lasix than with beta blockers.
  3. SOME increase risk for bradycardia. Drugs that by nature directly reduces the HR
    - EX: A beta blocker by nature directly lowers heart rate! SO, you need to know their HR BEFORE giving them! But, giving Lasix doesn’t by nature directly lowers your HR. It reduces BP by reducing fluid volume. So, you don’t need to check their HR before giving a diuretics!!
  4. NSAIDS reduce effectiveness of anti-hypertensive meds

Q

How do Diuretics lower BP?

A

Diuretics increase urine (make u pee more) –> Decreases volume/preload –> Decreases stroke volume and C.O. which decreases BP!

Q

What are the general principles for diuretic administration?

A
  1. FIRST LINE treatment for most patients!!!!
  2. Take meds early in the day
  3. Safety precautions for orthostatic hypotension, ESP IN OLDER PATIENTS! (it’s unsafe for them to get up by themselves without assistance since they’re more unsteady &vulnerable).
  4. Monitor weight and I&Os
    - Accurate weight measurement:
    1.) AFTER voiding
    2.) Before breakfast
    3.) Same typa clothing
    4.) Same scale & time of day
  5. Monitor electrolyes
    1) Potassium: 3.5-5.3 mEq/L
    - Signs of hyperkalemia:
  6. Muscle twitching –> cramp –> parasthsia (muscle irritable)
  7. Hypermotility & diarrhea
  8. Cardiac dysrythmia
  9. Lowers BP
    - Signs of hypokalemia:
  10. weakness, fatigue, and tired muscle
  11. decreased motility, N/V, & ILLEUS (gut not working)
  12. Cardiac arrhythmia
  13. Alkalosis, shallow breathing, irritibality, & thready pulse

2.) Sodium electrolytes
- Signs of Hyponatremia:
1) SALTLOSS (Stupor/coma, Anorexia&N/V, Lethargy, Tendon reflexes, Limp muscles, Orthostatic hypotension, Seizures&headache, Stomach cramping).

  1. DIETARY changes
    -Potassium with loops and thiazides: Potassium rich foods & potassium supplements
    - Potassium with K+ sparring: AVOID SALT substitutes (cz high in potassium)
  2. Monitor for signs of dehydration:
    1) MILD to Moderate dehydration: Dry mouth, headache & dizziness, sleepiness, concentrated urine (Darker color), & CONSTIPATION
    2) SEVERE dehydration: Extreme thirst and dry membranes, little to no urine output & VS changes, change in LOC
  3. Key drug interactions:
    1) Digoxin: increased digoxin toxicity risk. Digoxin work on potassium receptor sites, so if there’s low potassium, that’s going to leave more room for digoxin cause an increase in digoxin toxicity! SO, EVEN WITH A NORMAL LEVEL OF DIGOXIN, IF POTASSIUM IS LOW, IT CAN CAUSE DIGOXIN TOXICITY!
    2) LIthium- increased lithium toxicity risk

Q

What drugs can cause Heart block and why??
What can cause heart failure??? SIGNS?

A

Beta blockers and Calcium channel blockers!! because they both reduces CONDUCTION SPEED!! when conduction speed decreases, then that will cause 1ST degree AV Block (heart block) bc of the decrease conduction speed from SA node to AV node (that’s why PR segment would be widen a lil bit because conduction takes a longer time to the AV node than usual).

Drugs that decreases contraction strength will cause heart failure!! because since blood isn’t pumping blood out as much bc contraction strength has decreases.
then you won’t get good preload pushing the blood out in return (Starling Mechanism) which causes decrease in Preload and blood to build up and build up causing edema. This the same sign like LOW PERFUSION bc heart failure causes fluid not going to all over the body (poor perfusion); signs include SOB, altered mental change, drowsiness, decreased capillary refill, etc…

Q

What drugs can cause HEART BLOCK OR 1ST DEGREE AV BLOCK??? WHY??

A

Beta blockers and Calcium channel blockers!!!!

Because 1ST degree AV block happens when the conduction from SA node to AV node takes a long time (that’s why PR segment is widen if u see the ECG) And these drugs cause it because they both DECREASES CONDUCTION SPEED!!!!

Q

Which Antihypertensives do you need to ASSESS the patients HEART RATE BEFORE giving it??

A

(remember from the general principles!!!!! it’s only those drugs that work directlY on reducing the heart rate because they may cause bradycardia!! so a pt. with diuretic wouldn’t need to be checked for HR bc they don’t directLY by nature work on reducing the HR but more on reducing the volume)!!!

Q

What drugs can cause Heart failure? What signs would you see?

A

Beta blockers and Calcium chanel blockers! because both decreases CONTRACTION strength. heart won’t have enough force to pump blood out, then fluids won’t be perfused to the whole body and fluids gonna pile up and up causes edema (pulmonary edema = left side of heart; and peripheral edema = right side). SO SIGNS OF HEART FAILURE IS ALSO SIGNS OF POOR PERFUSION!!! Including: weakness, fatigue, mental status changes, SOB, decreased capillary refill, ect…

Q

If someone is on diuretics, would you want to dehydrate them patient or no????

A

YES! MAKING SURE THEY’RE still drinking good fluid volume!!! ( if they’re dehydrated it can cause them to have vascoconstriction in order to compensate which causes increased in bp.) make sure u hydrate them so that this doesn’t happen

44
Q

What are the 6 Essential things to know about Beta blockers????

A
  1. Heart rate decreases
    (ASSESS HR BEFORE GIVING TO PREVENT BRADYCARDIA)
  2. **Can cause/worsen heart blocks (1st degree AV Block) because we’re slowing down conduction speed thru the AV node!!
  3. Monitor for heart failure!! Because decreases in contraction strength will cause this which leads to low perfusion. thus SIGNS of heart failure is LOW PERFUSION: SOB, edema, Altered mental changes, fatigue, etc..
  4. Common side effects: Fatigue, Weakness, “Beta blocker Blues” or Depression, Sexual dysfunction, and Weight gain!!!
  5. Watch for diabetic patients!!!! WHY?
    1.) “Masking” of symptoms of Hypoglycemia
    2.) Decreased GLUCONEOGENESIS or GLYCOGENOLYSIS
  6. Relative selectivity vs. Non-selective (Non selective drugs HAVE MORE SIDE EFFECTS!!!!). Blockade of beta 2 receptors can cause: Bronchoconstrition –> bad for ppl with pulmonary disease; Inhibition of glycogeneolysis with SOME beta blockers (NOT METOPROLOL***)
    - Bad for those who are diabetics and taking insulin
  • Selective: Metoprolol, Atenolol, Esmolol
