DOC?

A
  • DOC1: linsinopril ACE since she is a diabetic and this can protect her kidneys and also treat peripheral neuropathy, have her come back in two weeks and check to see if she needs a diuretic
  • DOC2: if in two weeks still elevated use a thiazide diuretic but increase monitoring of BS because thiazides can increase BS

DOC? 2

HTN but need to rule out if he has HF or COPD

Q

explain how iburprofen uses causes an increase in BP?

A

this decreases the PROSTAGLANDIN A2 that dilates the renal artery and causes a retention in Na

without this the renal artery is more constricted so it activates the renin-system to increase BP

Q

does ibuprofen counteract the effect of anti-HTN meds?

A

yes! because it decreases the amount of prostaglandin A2, this keeps the renal arteries dilated so without it they constrict

RAAS becomes activated and so you get retention of Na

Case 16: 35 year old lady with HTN started on a ACE developed a dry cough. pretreatment BP was 160/100. last mentral cycle was 2 months prior. Lisinopril and albuterol.

DOC? what do you need to do?

A

STOP THE MEDS!!! when was her last period? she might be pregnant!!

if pregnant: get OBGYN on the phone to consult because lisinopril is a tetragen category D, GO straight to OBYGN

Case17: 30 year old african american male with BP 155/105 on three visits who declines tx because he has no money. stressful job as narcy. father died at 40 from MI.

DOC? and DOC based on cost?

A

Q

explain what happens to the MOA of thiazide diuretics after two weeks? if the patient was black and it didn’t control their BP after two weeks, what would you next two options be?

before two weeks they act as DIURETIC

after two weeks they become a VASODILATOR

switch in MOA

If after two weeks the BP isn’t controlled and the pt is black, may consider uping the diuretic OR starting CCB

Case 17a: 45 year old white male with right shoulder pain from a car crash last week. no head trauma. BP 175/100 but no organ damage, headache, or changes in vision. his pain is killing him. eGFR is 110 ml/min

DOC? what should you ask him about? what is causing his HTN?

A

HTN due to pain since UA and eGFR wnl (suggests pain)

hydrocodone/acetaminophen 5/325 (vicodin)

ask this pt if he has been taking NSAIDS as well ibuprofen because it can increase BP so switch to acetaminophen if so

*treat his pain first then have him come back in a couple days and recheck his BP and reevaluate if he still needs meds!

case 17b: 70 year old caucasion main with HTN that has been well controlled on lisinopril 20 mg. he has gained 10 pounds over the last 6 months and his pain in his knees has gotten work and uses a OTC. his BP today is 175/105 with eGFR 30 ml/min. high sodium levels.

DOC?

A

he takes NSAID over the counter which decreases prostaglandin causing renal constriction and salt retention, switch to acetaminophen SNOWBALL, THE WORSE THEIR OA GETS THE MORE PAIN MEDS THEY TAKE THE WORSE THEIR BP GETS

DOC1: stop the ibuprophen switch to acetaminophen

*recheck him later and see how much it has effected his BP

if still elevated DOC2: increase his ACE lisinopril

why do we treat a persons triglycerides?

A

LOWERING TRIGLYERCIDES DONT’ KNOW IF IT HELPS WITH CV DISEASE, BUT WITH TRI HIGH THEY ARE AT RISK FOR PANCREATITIS SO TREAT FOR THIS

91
Q

Case 23: 60 year old with pharyngitis and a fib. Anaphylaxis to PCN. DOC?

A
  • clindamycin
    • can’t use penicillin, cephalosporins (since anaphylaxis) macrolides and fluoroquinolones cause QT prolongation so can’t use these

A

random!

A

prevent against stroke

97

what is a SE of warfarin/

A

bruising

99

A

metoporlol succinate

dabigatran

101

amiodarone

what do you want to do for this patient? what would the DOC be if you found a positive result?

A
  • event monitor to check for afib
    • if afib: BB and dabigatran

most likely use metopolol succinate in this cause since likely Paroxysmal afib and is episodic and pt not symptomatic

105

what can beta blockers cause in diabetics?

A

hypoglycemia

so can use it but increase monitoring of BS

106
