Study Notes
Kidney Perfusion and Function
- Hypovolemia: Low blood volume negatively impacts kidney function, potentially causing damage. Pre-renal conditions can harm the kidneys.
- Sepsis: Kidney damage can result from sepsis.
- GFR (Glomerular Filtration Rate): A crucial indicator of kidney function. Maintaining a GFR above 90 is desirable.
- Peripheral Shunts: Constant assessment is necessary.
- Erythropoietin: Kidney injury impairs the production of erythropoietin, a hormone essential for red blood cell production.
- Chronic Kidney Disease (CKD): Characterized by edema or swelling. Higher potassium (hyperkalemia) is a common complication due to kidney impairment.
- Potassium-Sparing Diuretics: Spironolactone retains potassium in the body, so potassium-rich foods like spinach, tomatoes, bananas, and potatoes should be moderate or avoided.
- Hydrochlorothiazide: This diuretic acts on the early distal tubule. Take it in the morning. Monitor potassium levels closely.
- Furosemide: A more potent diuretic acting on the loop of Henle. Given if lung crackles are present. Monitor potassium levels.
- CKD Stages: Stages range from 1-5. Stages 1-3 may be asymptomatic. Stage 5 shows severely low GFR (around 15). Aim for a GFR above 60 (ideally above 90).
- Kidney Transplant Considerations: If waitlisted, don't take blood pressure or insert IVs on the dialysis fistula side. Listen for bruits using a bell.
- Acute Kidney Injury (AKI): Maintaining a mean arterial pressure (MAP) of 65 or higher is key. Monitor fluid balance (Strict I&O).
- Lethargy (in AKI): A sign of inadequate perfusion; blood flow preferentially going to heart & lungs.
Cardiovascular Issues
- Angina: Chest pain.
- Stable: Often activity-related; Treat with beta-blockers (atenolol).
- Unstable: Urgent; Treat with beta-blocker (atenolol) plus sublingual nitroglycerin PRN.
- Prinzmetal: Requires calcium channel blockers (e.g., diltiazem).
- Myocardial Infarction (MI): Heart attack.
- STEMI: Full-blown heart attack.
- NSTEMI: Possible heart attack; Check troponin levels.
- MONA: Treatment protocol for heart attacks: Morphine, Oxygen, Nitroglycerin, Aspirin.
- Congestive Heart Failure: Pulmonary edema treated with ambuterone, which is toxic to the lungs.
- Antiarrhythmics: Medications to treat abnormal heart rhythms.
- Sodium Channel Blockers: Procainamide. Works on both Na and some Ca channels; use only as needed.
- Calcium Channel Blockers: Diltiazem dilates coronary arteries and can cause hypotension and bradycardia. Be aware of patient position changes.
- Heart Action Potentials: Depolarization = contraction; Repolarization = resting. The PQRST waves represent different phases of the heartbeat.
- P Wave - atrial contraction/depolarization
- QRS Complex - ventricular contraction/repolarization
- T Wave - ventricular repolarization
Cardiovascular Shock
- Shock: Conditions impacting blood pressure and blood flow.
- Hypovolemic Shock: Blood loss reduces blood volume, leading to low MAP (mean arterial pressure), fatigue, and decreased urine output. Treats with potent vasoconstrictors (norepinephrine, Vasopressin).
- Norepinephrine may be used as initial treatment for shock.
- If no results or undesirable effects then alternative medicine is petolomine injection
- Severe Cases of Hypovolemic Shock: Expect whole blood transfusions to be administered.
Blood Products and Transfusions
- Blood Administration: Prime with normal saline only. MUST obtain consent. Ensure ABO/Rh matching and double-check RN information. Monitor vital signs (temperature, blood pressure, heart rate) at beginning and end of transfusion, and during administration. Observe for signs of reaction(single degree rise).
- Blood Reaction Window: Administration takes 30 minutes, watch for reactions within that window. Whole blood is used for severe losses, and is given for 50% blood loss.
Other Topics
- Urinary System: Cranberries are acidic and make urine bacteriocidal (to a certain degree).
- Neutropenia: Filgrastim for low neutrophils.
- Low Platelets:
