Q

Solution Tonicity

hypotonic, isotonic, hypertonic

A

Tonicity: Ability of a solution to cause a cell to lose or gain water

Hypotonic: Treat dehydration with normal B/P (water moves into the cell)
Isotonic: Does not change tonicity of blood - treat dehydration w/ low B/P
Hypertonic: Treat cellular edema - Cell shrinks

Used for HF
THERAPEUTIC EFFECTS
Causes heart to beat more forcefully and slowly (Positive Inotropic effect)

26
Q

Milrinone administration alerts

A

Used for HF, positive inotropic effect
IV pump, microdrip set
only use for 2-3 days

Davis Drug Guide:

  • High Alert… heightened pt risk with error
  • —-Ventricular Arrhythmia’s
  • —-Monitor ECG continuously during infusion
27
Q

Angina vs MI diagnosis

A 
ANGINA
chest pain caused by insufficient O2
Short duration - goes away with stress reduction
RELIEVED BY NTG (vasodilator)
stable-exertion
unstable-no exertion

MI
Heart attack
NOT RELIEVED BY NTG

28
Q

Calcium Channel Blockers Mechanism of Action

A

Relax arteriolar smooth muscle thus lowering BP
Dilate coronary arteries
Reduce workload
Stop dysrhythmias

29
Q

MONA

A 
Immediate treatment of MI
MORPHINE - treat pain, reduce stress
OXYGEN - given b/c lacking O2 in tissues
NITROGLYCERINE - vasodilation
ASA (aspirin) - Anti-platelet, makes less sticky
30
Q

NTG side effects

A

Hypotension

Severe Headache

31
Q

NTG teaching

A

Take sublingual Q5 min x 3 PRN for pain

32
Q

Retaplase Therapeutic Indication

A

Retaplase is a Thrombolytic

Dissolves clots obstructing coronary artery disease

33
Q

Albumin Teaching

A

Most common colloid used

May cause fluid overload - distended neck veins, pulmonary edema, cough, HTN, tachycardia

34
Q

Colloid Administration Assessment

A

Listen for crackles in the lungs

35
Q

A 
CHYRSTALLOIDS
IV solutions contain electrolytes similar to plasma
Mimic body's extracellular fluid
Trauma Pt's
NS, LR, D5W, HS

COLLOIDS
Proteins pull water into vessels - hypertonic
Proteins, starches or other large molecules
Albumin most common

36
Q

Dopamine administration

A

IV only
May cause dysrhythmias
Increase BP and force of contraction

37
Q

Shock Treatment Priority

A

ABC’s of life support
Airway
Breathing
Circulation

38
Q

Palpitations
Chest Pain
Weakness
Fatigue
New Dysrhythmias
39
Q

Beta Blocker Client Teaching

A 
Check pulse and call if <60
Do not discontinue abruptly
May mask hypoglycemia
Don't give with pulmonary problems, may cause bradycardia
Used to prevent MI and Angina
40
Q

Cardiac Output and Tachycardia

A

cardiac output DECREASES with tachycardia

41
Q

Cardioversion Rationale

A

Electrodes placed on chest, send electrical shocks to restore normal rhythm

Safer with less side effects

42
Q

Dysrhythmias Pathophysiology

A

Abnormal electrical conduction
Symptoms (none to sudden death)
Atrial fibrillation most common

43
Q

Heparin Side effects

A 
Heparin - Anticoagulant

Watch for bleeding
---Internal s/s---
low BP
High HR
Pallor
Weakness
Low Hgb/Hct
44
Q

Heparin Outcomes

A

Goal:

  • No bleeding
  • No unusual clot formations
45
Q

INR values

A

Ideal 2-3

46
Q

Lovenox Administration (enoxaparin)

A

Fewer follow up lab tests
More stable response
Less thrombocytopenia (low blood platelet count)
SubQ in abdomen only

Protamine sulfate - Reverse

Anticoagulant.. DVT

47
Q

Warfarin lab tests

A 
Oral anticoagulant
Prothrombin times (PT) or INR frequently, 2-3 ideal
48
Q

Warfarin Overdose Treatment

A

Warfarin - Oral anticoagulant
Immediate reversal is Vit. K
Blood and plasma if severe bleeding occurs
If not bad, withholding a dose is usually sufficient

49
Q

Warfarin Teaching

A 
Warfarin - Oral anticoagulant
Avoid Vit. K
Serious side effects - bleeding
No alcohol, other Rx, otc or herbal products
Frequent INR testing
50
Q

Alcoholism and Folic Acid

A

Folic Acid - Needed for RBC production

Alcoholism interferes with folate metabolism in the liver

51
Q

Epoetin Assessment Post Admin

A

Common adverse effect is HTN - Beta blockers can be given concurrently

CHECK BP BEFORE AND AFTER

52
Q

Epoetin Teaching

A

Secreted by kidneys, TRAVELS TO BONE MARROW, interacts with stem cells to INCREASE ERYTHROCYTE PRODUCTION
HTN common adverse effect. Beta blockers given concurrently

53
Q

Filgrastim Mechanism of Action

A

Increase neutrophil production

54
Q

Iron Administration Teaching

A

Free iron is toxic - common cause of poison in children
IRON DEFICIENCY MOST COMMON CAUSE OF ANEMIA

TAKE WITH FOOD
STAY UPRIGHT FOR 30 MINUTES AFTER TAKING
DON’T TAKE BEFORE BEDTIME

55
Q

Oprelvekin Teaching

A

Platelet enhancer
Stimulates production of megakaryocytes and thrombopoietin
Increases platelet count

56
Q

INR

A

International Normal Ratio - Determines clotting rate
>6 Give Vit. K
