Key side effects of digoxin? Any black box warnings?
Has very narrow therapeutic margin:
- normal: 0.5-2.0
- desired level: 0.8
Digoxin toxicity:
- vision changes, N/V, dizziness
- increased risk of hypokalemia
- can be life-threatening
Key side effects of ACE inhibitors? Any black box warnings?
- generally well tolerated and absorbed
- hyperkalemia
- dizziness
-
cough (“ACE cough”)
– related to kinins and activation of arachidonic pathway and prostaglandin production
– begins 1-2 weeks of initiation; typically resolves within few days of stopping med - angioedema
BLACK BOX WARNING:
- serious fatal abnormalities: not given in pregnancy and caution in childbearing-age women
- esp in 3rd trimester
- contraception very important

Long- acting Beta Agonist: Black-box warning and information
salmeterol (Serevent) and formoterol (Foradil) should not be used without a steroid in asthma for all ages
Need to weigh the risk vs benefits
NEVER USE AS A RESCUE INHALER
- SHOULD NOT BE USED IN CHILDREN LESS THAN AGE 4 and NEVER WITHOUT A STEROID
USE WITH A STEROID!!
What should be avoided when taking Levothyroxine/ Armour Thyroid
Calcium containing medications, antacids, or iron supplements
Phenytoin (Dilantin): what type of med? How does it work? Indications?
Sodium channel blocker
- works to stabilize the neurons from becoming too excited
- stops the spread of seizure activity in the motor cortex
- highly (90%) protein-bound drug: increased risk of drug interactions
Indications:
- tonic-clonic seizures
- status epilepticus
- prophylaxis for surgery
Carbamazepine: What needs to be monitored?
Labs:
- CBC: especially WBC
- Drug level: 4-12 mcg/mL
Monitor drug levels, sodium, CBC, LFTs, and BUN/Cr especially in those with renal impairment
Valproic Acid/Valproate (Depakote): Administration and monitoring
Can give with? Monitor what? Therapeutic range?
- can be given with phenytoin
- take with food
- can cause liver toxicity, need to monitor LFTs
-
narrow therapeutic range
– need to check levels (50-100 mcg/mL) - must be diluted when given IV with at least 50mL NSS or D5W
– give over an hour (no more than 20mg/min) - avoid sudden withdrawal
- monitor CBC because can cause thrombocytopenia
Nursing considerations for pt on anti-platelets - how long to stop before surgery? take how often? who can stop med?
Who should not be on anti-platelets (6)
Should be stopped at least 2-5 days before surgery
Must take everyday unless told otherwise
Only provider can stop medication
DO NOT GIVE-
* Known bleeding disorder
* * Active bleeding
* * Closed head injuries
* * CVA until prove no bleed
* * Pregnancy (risk benefit)
* * Lactation
Nursing considerations for warfarin? How long does it take to clear the body?
-Takes 4-7 days to take effect
-Should be taken in the evening
-Requires frequent lab monitoring (PT/INR)
-Narrow therapeutic range
-Works slowly compared to heparin
online: After being stopped, warfarin takes 5–7 days to clear the body.
Aspirin Drug interactions
Oral anticoagulants, Heparin, Methotrexate, oral DM meds, and Insulin – can increase the risk of toxicity when taken with ASA
* Steroids may decrease the ASA effect and cause ulcers
* ACE and Beta Blockers
* NSAIDS
Contraindication for tPA (7)
- Uncontrolled BP (185/110)
- History of Hemorrhagic Stroke, aneurysm, or AV
malformations - Heparin in the last 48 hours
- Current oral anticoagulant
- DOAC use
- Surgery within 3 months
- Platelet count <100,000
What specific actions does the nurse need to take for loop diuretics? Any labs, vitals, nursing considerations?
- monitor potassium level!
– monitor other electrolytes too, but potassium very important - monitor I&Os
- monitor blood sugar
What specific actions does the nurse need to take with digoxin? Labs, vitals, nursing considerations?
Antidote? Check? Monitor? Caution in?
Antidote: digibind
- always check apical HR and call MD if less than 60

- rapid onset and absorption
caution in:
- pregnancy and lactation
- pediatric and geriatric
- renal insufficiency
