Learn the nursing considerations and side effects of the hypertensive drugs.
Side effects associated with Fenoldopam, a direct vasodilator?
Tachycardia, angina, headache, nausea, flushing.
Nursing Considerations for Fenoldopam?
IV use only for hypertensive crisis in hospitalized patients.
Use cautiously in patients with glaucoma.
Patient should remain supine for 1 hr after administration
Side effects associated with hydralazine, a direct vasodilator?
Headache, nausea, flushing, palpitation, tachycardia, dizziness, and angina.
Hemolytic anemia, vasculitis, and rapidly progressive glomerulonephritis. .
Nursing Considerations for Hydralazine?
IV use for hypertensive crisis in hospitalized patients.
Twice-daily oral dosage.
Not used as monotherapy because of side effects.
Contraindicated in patients with coronary artery disease; use with caution in patients >40 yr.
Minoxidill (Loniten)- what side effects should the nurse monitor for?
Reflex tachycardia, marked sodium and fluid retention (may require loop diuretics for control), and hirsutism.
May cause ECG changes (flattened and inverted T waves) not related to ischemia.
Nursing Considerations for Minoxidill?
Reserved for treatment of severe hypertension associated with renal failure and resistant to other therapy. Once- or twice-daily dosage.
Nitroglycerin - what adverse effects should be expected?
Hypotension, headache, vomiting, flushing.
Nursing Considerations for Nitroglycerin? (a direct vasodilator) ?
IV use for hypertensive crisis in hospitalized patients with myocardial ischemia.
Administered by continuous IV infusion with pump or control device. \
What side effects should you monitor for in a patient taking Sodium Nitroprusside?
Acute hypotension, nausea, vomiting, muscle twitching.
Signs of thiocyanate toxicity include anorexia, nausea, fatigue, disorientation.
Nursing considerations for a patient taking Sodium Nitroprusside?
IV use for hypertensive crisis in hospitalized patients.
Administered by continuous IV infusion with pump or control device.
Intraarterial monitoring of BP recommended.
Wrap IV solutions with an opaque material to protect from light; stable for 24 hr.
Metabolized to cyanide, then thiocyanate. Monitor thiocyanate levels with prolonged use (>3 days) or doses (≥4 mcg/kg/min).
Trimethaphan, a Ganglionic Blocker - What side effects?
Visual disturbance, dilated pupils, dry mouth, urinary hesitancy, subjective chilliness.
Nursing Considerations for Tripethaphan?
IV use for initial control of BP in patient with dissecting aortic aneurysm.
Administered by continuous IV infusion with pump or control device,
What are the side effects that you should monitor for in Angiotensin-Converting-Enzyme-Inhibitors Benazepril (Lotensin), captopril (Capoten)
enalapril (Vasotec)
fosinopril (Monopril)
lisinopril (Prinivil, Zestril)
moexipril (Univasc)
perindopril (Aceon)
quinapril (Accupril)

trandolapril (Mavik)
Hypotension, dizziness, loss of taste, cough, hyperkalemia, acute renal failure, skin rash, angioedema.
Nursing Considerations for Benzepril, and all of the other Angiotensin-Converting Enyzme Inhibitors, ending in “pril” ?
Aspirin and NSAIDs may reduce drug effectiveness.
Addition of diuretic enhances drug effect.
Should not be used with potassium-sparing diuretics.
Inhibit breakdown of bradykinin, which may cause a dry, hacking cough.
Captopril may be given orally for hypertensive crisis.
Nursing Considerations for Enalapril, an Angiotensin-Converting Enzyme Inhibitor?
This drug inhibits ACE when oral agents are not appropriate.
Given IV over 5 min; monitor BP
What side Effects should you monitor for Angiotensin II Receptor blockers?
(candesartan (Atacand)
eprosartan (Teveten)
irbesartan (Avapro)
losartan (Cozaar)
olmesartan (Benicar)
tasosartan (Verdia)
telmisartan (Micardis)
valsartan (Diovan)
Hyperkalemia
Decreased Renal Function
Nursing Considerations for Angiotensin II receptor blockers?
(candesartan (Atacand)
eprosartan (Teveten)
irbesartan (Avapro)
losartan (Cozaar)
olmesartan (Benicar)
tasosartan (Verdia)
telmisartan (Micardis)
valsartan (Diovan)
Full effect on BP may not be seen for 3-6 wk.
Do not affect bradykinin levels. Therefore acceptable alternative to ACE inhibitors in people who develop dry cough.
Renin inhibitors - Alisken- What side effects should you monitor for?
Rash, diarrhea, increased creatine kinase level, cough, hypotension, torsades de pointes, acute renal failure, angioedema.
Nursing Considerations for Alisken, a Renin Inhibitor?
May cause angioedema of the face, extremities, lips, tongue, glottis, and/or larynx.
Not to be used in pregnancy.
What side Effects should you monitor for with Calcium Channel Blockers -
Amlodipine (Norvasc)
clevidipine (Cleviprex)
diltiazem extended release (Cardizem CD, Cardizem LA, Dilacor XR, Tiazac)
felodipine (Plendil)
isradipine (DynaCirc CR)
nicardipine sustained release (Cardene SR)
nifedipine long acting (Adalat CC, Procardia XL)
verapamil intermediate release (Isoptin, Calan)
nisoldipine (Sular)
verapamil long acting (Isoptin SR, Covera-HS, Calan SR)
verapamil timed release (Verelan PM)
Bradycardia, first-degree AV block, nausea, headache, dizziness, peripheral edema, flushing, rash, gingival hyperplasia, constipation (with verapamil).
What are the Nursing Considerations for Calcium Channel Blockers?
Use with caution in patients with heart failure. Contraindicated in patients with second- or third-degree heart block.
Avoid grapefruit when on nifedipine.
Use of sublingual short-acting nifedipine in hypertensive emergencies is unsafe and not effective. Serious adverse events (e.g., stroke, acute Ml) have been reported.
IV nicardipine available for hypertensive crisis in hospitalized patients. Change peripheral IV infusion sites every 12 hr.
Clevidipine is for IV use only.
What are the side effects that the nurse should monitor for in a patient taking a Thiazide Diuretic?
( bendroflumethiazide (Naturetin)
benzthiazide (Aquatag, Exna)
chlorothiazide (Diuril)
chlorthalidone (Hygroton)
hydrochlorothiazide (Microzide, Esidrix, HydroDIURIL, Oretic)
methyclothiazide (Enduron)
metolazone (Zaroxolyn)
trichlormethiazide (Metahydrin, Naqua))
Fluid and electrolyte imbalances: volume depletion, hypokalemia, hyponatremia, hypochloremia, hypomagnesemia, hypercalcemia, hyperuricemia, metabolic alkalosis; CNS effects: vertigo, headache, weakness. GI effects: anorexia, nausea, vomiting, diarrhea, constipation, pancreatitis.
Sexual problems: erectile dysfunction, decreased libido.
Dermatologic effects: photosensitivity, skin rash.
Blood dyscrasias; decreased glucose tolerance.
Nursing Considerations for Thiazide diuretics?
Monitor for orthostatic hypotension, hypokalemia, and alkalosis. T
hiazides may potentiate cardiotoxicity of digoxin by producing hypokalemia.
Dietary sodium restriction reduces the risk of hypokalemia. NSAIDs can decrease diuretic and antihypertensive effect of thiazide diuretics.
Advise patient to supplement with potassium-rich foods. Current doses are lower than previously recommended.
What side effects should be monitored for in a patient taking a Loop Diuretic?
( bumetanide (Bumex)
ethacrynic acid (Edecrin)
furosemide (Lasix)
torsemide (Demadex))
Fluid and electrolyte imbalances as with thiazides, except no hypercalcemia.
Ototoxicity: hearing impairment, deafness, vertigo, that are usually reversible.
Metabolic effects: hyperuricemia, hyperglycemia, increased LDL cholesterol and triglycerides, decreased HDL cholesterol.
