Pharm Exam 1 Flashcards
Antibiotics, Antiseizure, Vasopressors, Antidysrhythmic, Steroids (20 cards)
Assessments for antibiotics
1.) Allergies
2.) Liver/kidney labs b/c many antibiotics are metabolized in the liver and excreted through the kidneys. Vanco requires BUN/creatinine monitoring b/c it can cause nephrotoxicity. Flagyl requires AST/ALT monitoring b/c it can cause hepatotoxicity.
3.) Blood Cultures to identify the specific bacteria causing the infection. This ensures the antibiotic given is effective against the pathogen.
4.) Vanco trough levels should be drawn 30 minutes before the next dose to monitor for therapeutic range and avoid toxicity
Why is it important to monitor trough levels for Vancomycin, and when should they be drawn?
Trough levels for Vancomycin are drawn 30 minutes before the next dose. If the trough level is too high, it can lead to nephrotoxicity and ototoxicity. The trough level is too low, the antibiotic may not be effective in treating the infection.
What are the common side effects of antibiotics? (3)
1.) Photosensitivity - Patients should avoid prolonged sun exposure & use sunscreen
2.) Ototoxicity - More common with Vanco, patients should report hearing changes, tinnitus, dizziness
3.) Superinfection (C. Diff or yeast) - Patients should report severe GI issues or itching in mouth or genital area
Adverse reactions to antibiotics
1.) Nephrotoxicity
2.) Hepatotoxicity
3.) Allergic reaction
What severe reaction does Vancomycin cause?
Red Man Syndrome is caused by infusing Vancomycin too quickly. Symptoms include flushing, red rash, and itching that form on the face, neck, and upper chest. Slowing down the infusion can stop this reaction.
What do Vancomycin and Flagyl treat that no other antibiotics can?
C. Diff
What severe reaction can Sulfas and Flagyl cause?
Steven Johnsons Syndrome (SJS) is a severe life threatening reaction. Symptoms include a red, blistery rash that progresses to skin peeling and ultimately necrosis. Patients should seek immediate medical attention.
Patient education for antibiotics
1.) Complete the full course of antibiotics even if symptoms improve. Stopping antibiotics early can lead to antibiotic resistance, or recurrence of infection.
2.) Take w/food to avoid GI upset
3.) Drink plenty of fluids to help prevent nephrotoxicity and promote excretion of the drug
What are 3 safety considerations with antibiotics?
1.) Avoid alcohol especially with Metronidazole (Flagyl) as it can cause severe reaction w/ symptoms like vomiting, headache, and tachycardia.
2.) Many antibiotics (Tetracyclines & Sulfas) are toxic in pregnancy. Always check a pregnancy test before administration & use safter alternatives if needed.
3.) IV Extravasation - Stop the infusion immediately; start a new IV at another site; Apply a warm/cold compress as needed
What is the primary use of Adenosine?
Adenosine is the FIRST line treatment for SVT
How does Adenosine affect the heart?
Adenosine briefly stops the heart to restore NSR. It is known as the “IT Med” b/c it “turns off/on the heart”
Side effects of Adenosine
- Brief asystole
- Flushing
- Angina
- SOB/dyspnea
- Sense of impending doom
- Hypotension/bradycardia
Nursing Considerations for Adenosine (5)
1.) Warn pt of side effects before administration
2.) Have crash cart nearby for emergencies
3.) Hook pt up to telemetry monitoring before administration
4.) Administer in the AC
5.) After admin, slam 20mL saline flush and elevate the arm to promote circulation
What is the primary use of Amiodarone/when do we use it?
Amiodarone is the LAST resort drug for Afib/Aflutter that has not responded to other medications.
What should you try before Amiodarone?
Beta Blockers and Calcium Channel Blockers
What are the adverse effects of Amiodarone?
1.) CNS - Ataxia, hallucinations, tremors
2.) Integumentary - Photosensitivity, /grayish-blue skin/cyanosis
3.) Eyes - Vision changes - BL exam
4.) Hypo/hyperthyroidism - BL labs
5.) Pulmonary Toxicity - BL pulmonary function tests & CXR
6.) Cardiac Toxicity - Can cause HF - BL EKG/ECHO
7.) Hepatotoxicity - BL labs
Nursing Considerations for Amiodarone
1.) Give PO Adenosine 1hr before starting Amiodarone drip
2.) IV: Monitor for hypotension/bradycardia
3.) No grapefruit juice
4.) Use sunscreen
5.) Signs of toxicity
6.) Appointments for baseline labs
7.) Side effects may persist after med is D/C’d
What is the primary use of Lidocaine?
Lidocaine is used for ventricular dysrhythmias like PVCs and Vfib/Vtach
What are side effects of Lidocaine?
“Lidocaine brings things down in your LAP”
1.) Hypotension & bradycardia
2.) CNS Changes - Confusion, dizziness, drowsiness, paresthesia, and seizures
3.) Respiratory arrest
Nursing considerations for Lidocaine (3)
1.) Frequent neuro checks for changes
2.) Monitor tele for dysrhythmias
3.) Keep the crash cart nearby
