EXAM #2: REVIEW QUESTIONS: modules 7-10 Flashcards
Unit 7: Cardiac Agents
What are some non-pharmacologic measures that can be used to control or prevent the symptoms of cardiovascular disease?
good diet, reduce fat intake , exercise, no alcohol
What are some symptoms of digoxin toxicity?
confusion,
loss of appetite,
nausea,
vomiting,
diarrhea,
vision problems
Gi distress
HYPERKALEMIA
LIFE THREATENING DYSRHYTHMIAS
Decrease heart rate lower then 60
How do beta blockers work?
by decreasing the activity of the heart causing vasodilation to the myocardial muscle
by blocking hormones like adrenaline
How do calcium channel blockers work? What is a side effect?
Calcium channel blockers work by relaxing blood vessels and reducing pressure on the heart.
side effects=, fatigue and swelling in the abdomen, feet, and legs.
How do ACE inhibitors work?
They block angiotensin 1 and angiotensin 11
Therapeutic class= anti hypertensive
Electrolyte imbalance: risk for hyperkalemia
They lower BP by relaxing blood vessels
How do ARBs work?
SARTAN
BLOCK receptors for Angiotension 11
Therapeutic class: antihypertensive
Electrolyte imbalance: risk for hyperkalemia
What drugs might be used to treat pulmonary edema?
Diuretics= such as furosemide (Lasix), decrease the pressure caused by excess fluid in the heart and lungs.
What is angina pectoris?
is a type of chest pain caused by reduced blood flow to the heart. Angina is a symptom of coronary artery disease. Angina is also called angina pectoris. Angina pain is often described as squeezing, pressure, heaviness, tightness or pain in the chest.
What are 3 electrolytes responsible for cardiac action potentials?
sodium (Na+), potassium (K+), and calcium (Ca2+)
Name some adverse effects of blood thinners.
Excessive bleeding!!!!
passing blood in your urine.
passing blood when you poo or having black poo.
severe bruising.
prolonged nosebleeds (lasting longer than 10 minutes)
vomiting blood or coughing up blood.
sudden severe back pain.
difficulty breathing or chest pain.
What do anticoagulants do?
Anticoagulants are medicines that help prevent blood clots. They’re given to people at a high risk of getting clots, to reduce their chances of developing serious conditions such as strokes and heart attacks. A blood clot is a seal created by the blood to stop bleeding from wounds.
How does nitroglycerin spray lower BP?
Vasodilation
Decrease peripheral resistance
What should you do if nitroglycerin treatment is not effective for chest pain?
If you typically use nitroglycerin to relieve angina and if one dose of nitroglycerin has not relieved your symptoms within 5 minutes, call 911.
When should digoxin be withheld?
Withhold dose and notify health care professional if pulse rate is <60 bpm in an adult, <70 bpm in a child, or <90 bpm in an infant. Notify health care professional promptly of any significant changes in rate, rhythm, or quality of pulse.
When getting up a patient on an antihypertensive medication, what should be taken into consideration? Why?
Orthostatic hypotension
Patient needs to get up slowly or else will fall down
How do patients develop cardiac dysrhythmias?
History of Mi
-electrolyte imbalance
-Blocked arteries in the heart (coronary artery disease)
-Changes to the heart’s structure, such as from cardiomyopathy
What is rebound hypertension?
Rebound hypertension occurs when blood pressure rises after you stop taking or lower the dose of a drug
Why should decongestants be avoided with severe hypertension?
Sympathomimetic
They both will increase BP
What are the catecholamines that stimulate the SNS?
The endogenous catecholamines in humans are:
-dopamine
-norepinephrine
- epinephrine
What antiplatelet drugs can cause tinnitus?
Medications that can cause tinnitus ·
- Aspirin and other NSAIDs
· 2. Benzodiazepines
· 3. Tricyclic antidepressants · - Certain antibiotics
What is the pharmacological action of anti-arrhythmic drugs?
BLOCKING the sodium membrane, potassium, and calcium channels
Decreasing myocardial excitability
What class of drugs acts on the kidneys to reduce fluid in the body, and indirectly reduce BP?
Diuretics, also called water pills, are a common treatment for high blood pressure. Find out how they work and when you might need them. Diuretics, sometimes called water pills, help rid your body of salt (sodium) and water.
Unit 8: Respiratory Agents
- What are some non-pharmacologic measures to prevent or control symptoms of respiratory diseases?
Minimize or stop smoking
Avoid asthma tiggers
What is the intended effect of expectorants?
Expectorants lubricate your airway. This helps loosen up the mucus and make the secretions in your airway thinner.
By loosening up the mucus, expectorants make your cough more productive.
What type of medications are more effective in treating acute asthma attacks?
Salbutamol , ventolin
Pharmacological class: SABA ( SHORT ACTING BETA 2 AGONIST)
Therapeutic class : BRONCHODILATOR
What should a client do after receiving inhaler medication?
Have patient rinse mouth and gargle with warm water about 2 minutes after treatment. Rinsing removes residual medication from mouth and throat, and helps prevent oral candidiasis related to steroid use.
What do antitussives do?
suppressing cough.
Antitussives act on the cough center in the brain and decrease the sensitivity of cough receptors.
How do systemic decongestants work?
Vasoconstriction
What should be assessed before and after inhalation?
-Assess pulse
-respiratory rate
-breath sounds
-pulse oximetry / 02 saturation
(This determines a baseline respiratory assessment prior to administration of medication)
What do bronchodilators do to the lungs?
Bronchodilators = VASODILATION making breathing easier.
They do this by relaxing the muscles in the lungs and widening the airways (bronchi)
They’re often used to treat long-term conditions where the airways may become narrow and inflamed.
How do antihistamines work?
•BLOCKING the H1 receptors
•stopping HISTAMINE from reaching its target.
~This decreases your body’s reaction to allergens
