Update | Verified Correct Questions &
Answers | Grade A
What should a nurse do when administering a Beta-Adrenergic Blocker like metoprolol?
Who is it contraindicated for?
Check heart rate and blood pressure due to its negative chronotropic and inotropic effects.
If vital signs are low, hold the medication and notify the physician.
Contraindicated for asthma patients.
How to monitor the effectiveness of diuretic therapy?
Assess fluid balance, weight, and blood pressure regularly.
What is monitored when a patient takes Digoxin (lanoxin)?
Digoxin serum levels are monitored due to its narrow safety range.
What does a Digoxin level >1.8 ng/dL indicate?
It indicates high levels and potential digoxin toxicity, as Digoxin is a negative chronotropic
medication.
What is the additional effect of Digoxin on the heart?
Digoxin is a positive inotrope, increasing myocardial contractility.
What are signs of Digoxin Toxicity?
Nausea, anorexia, visual disturbances (seeing halos), fatigue, and vomiting.
What should a nurse do before administering Digoxin?
Check the apical pulse for one full minute. If the heart rate is low (generally 60 bpm), hold the
medication and inform the practitioner.
How does Digoxin affect heart electrical activity?
It can suppress electrical activity within the heart and lower heart rate.
What is the treatment for toxic levels of Digoxin?
Digibind can be used to treat toxic levels.
, Explain how ACE inhibitors function.
ACE inhibitors block the conversion of angiotensin I to angiotensin II, reducing blood pressure
and fluid retention.
What are ACE inhibitors commonly used for?
Heart failure, hypertension, diabetic neuropathy, and post-myocardial infarction therapy.
How does Hypokalemia affect Digoxin therapy?
It increases the risk of Digoxin toxicity. Potassium levels <3.5 require immediate notification of
the physician.
What are the possible consequences of administering Nitrates with Viagra?
Severe hypotension can occur.
How can you measure the effectiveness of Digoxin in a heart failure patient?
Improved ability to perform activities of daily living (ADLs) and better walking ability.
What is an abnormal finding in patients taking Coumadin?
Black tarry stools, which may indicate bleeding. PT and INR should be monitored.
How can tolerance to transdermal Nitroglycerin be prevented?
Remove the patch for 6-8 hours to prevent tolerance buildup. Tylenol can be suggested for
headaches.
What are common adverse effects of organic Nitrates?
Headache, orthostatic hypotension, tolerance buildup, and reflex tachycardia.
What is the concern with calcium channel blockers and grapefruit juice?
Grapefruit juice can increase the concentration of calcium channel blockers in the blood, leading
to potential toxicity.
List some possible adverse effects of Lasix.
Hypokalemia, hypotension, hyperuricemia, hyperglycemia, and ototoxicity if IV push is too fast.
What should a nurse assess in patients taking Statins?
Muscle pain, tenderness, and weakness, which could indicate rhabdomyolysis.
Why are Ace Inhibitors commonly prescribed for diabetic patients with hypertension?
They slow the progression of kidney injury and diabetic neuropathy.
