WGU D398 MEDS – Questions With Detailed
Explanations
What are cardiac glycosides? Correct Answer - they are
medications that can enhance the force of cardiac contractions by
acting directly on the heart muscle.
What is the indication for digoxin (Lanoxin) Correct Answer -
cardiac glycoside prescribed for heart failure
Side effects unique to digoxin (Lanoxin) a cardiac glycoside?
Correct Answer - double vision, visual halos, inability to sleep,
irritability, tremors, seizures.
digoxin (Lanoxin) cautions Correct Answer - Severe kidney
and lung damage
amiodarone (Cordarone) action: Correct Answer - An
arrhythmia of the heart is an irregular heartbeat. This occurs when
the electrical signals that coordinate heartbeats malfunction.
Incorrect signaling causes the heart to beat excessively or quickly
(tachycardia), too slowly (bradycardia), or erratically (fibrillation).
amiodarone (Cordarone) indication Correct Answer -
Antiarrhythmic medicines comprise several drugs that suppress
various kinds of heart arrhythmias in diverse ways.
amiodarone (Cordarone) side effects: Correct Answer -
tremors, numbness, visual disturbances, lung scarring, or thickness
(known as pulmonary fibrosis)
amiodarone (Cordarone) cautions: Correct Answer - patients
with underlying heart block diseases; patients with thyroid disease;
,patients with allergic reactions to iodine (because of the large
amount of iodine contained in amiodarone)
metoprolol (Toprol) Indication: Correct Answer - Beta1
receptors are largely present in the heart, and their activation
results in an increase in the heart's pace and force of contraction as
well as a rise in blood pressure.
metoprolol (Toprol) action: Correct Answer - blood pressure-
lowering medicine and function by blocking the beta receptor in the
body.
metoprolol (Toprol) side effects: Correct Answer - dizziness,
fatigue, confusion, low blood sugar
metoprolol (Toprol) cautions: Correct Answer - Never stop the
drug without speaking to a doctor (may have withdrawal
symptoms). Inform the doctor of medication and disease history.
Some beta-blockers may interfere with diseases such as asthma or
chronic obstructive pulmonary disease and can worsen symptoms.
amlodipine (Norvasc) Indication: Correct Answer - amlodipine
are Calcium channel blockers are medications that also reduce blood
pressure.
amlodipine (Norvasc) action: Correct Answer - They act by
preventing calcium from entering the cells of the heart and arteries.
The calcium blockage reduces heart rate, hence lowering blood
pressure further. In addition, this class of drugs may be used to
alleviate chest discomfort (angina) and regulate an irregular
heartbeat.
amlodipine (Norvasc) side effects: Correct Answer - edema
(swelling), abdominal discomfort, and headache
, hydrochlorothiazide (Microzide) indication: Correct Answer -
hydrochlorothiazide (Microzide) is a diuretic and are medications
used to decrease blood pressure.
hydrochlorothiazide (Microzide) action: Correct Answer -
lowers blood pressure by helping rid the body of salt (sodium) and
water through increased urine.
hydrochlorothiazide (Microzide) side effects: Correct Answer -
diuretics commonly cause frequent urination, low potassium, and
low magnesium (supplements are sometimes given to maintain
electrolyte levels)
lisinopril (Zestril) indication: Correct Answer - lisinopril is an
Angiotensin-converting enzyme (ACE) inhibitors are drugs that
relax veins and arteries to reduce blood pressure.
lisinopril (Zestril) action: Correct Answer - ACE inhibitors are
medications that work by blocking an enzyme called ACE in the
body, which leads to a decrease in angiotensin II, a chemical that
narrows blood vessels. Reducing the levels of angiotensin II can help
to relax and widen blood vessels, which can improve blood flow and
lower blood pressure
lisinopril (Zestril) side effects: Correct Answer - The most
frequent side effect of ACE inhibitors is a dry cough, rash, and high
potassium.
lisinopril (Zestril) cautions: Correct Answer - A serious,
potentially life-threatening adverse effect is angioedema (swelling
under the skin). Use caution in pregnancy and lactation (can cause
birth defects).
