Flashcards in Exam 2- AKI and HIV/AIDS Deck (19)
What are the causes of prerenal AKI?
volume depletion (burns, hemorrhage, GI loss), hypotension (shock, sepsis), and renal artery stenosis
What are the causes of intrarenal AKI?
parenchymal damage to the glomeruli or kidney tubules; acute tubular necrosis
What are the causes of postrenal AKI?
obstruction distal to the kidney by conditions (renal calculi, strictures, blood clots, BPH, malignancies, and pregnancy)
Diagnostics for AKI?
- 50% or more increase in serum creatinine above baseline (normal creatine is 800 mL/day
- anuria 800 mL/day
What is the most immediate life-threatening imbalance seen in AKI?
Nursing care for AKI patients?
- monitor serum level
- daily weight
- Intake and Output
- reduce metabolic rate-- bed rest
- turn, cough, take deep breaths
- AVOID catheter due to high UTI risk
- bath in cool water if patient is itchy
- AVOID excess fluids
- treat underlying problem (burn, UTI, obstruction)
Adverse effects for HIV/AIDS meds?
- hepatotoxicity, nephrotoxicity and osteopenia, along with increased risk of cardiovascular disease and myocardial infarction
- cause fat redistribution syndrome and metabolic alterations such as dyslipidemia and insulin resistance which put the patient at risk for early-onset heart disease and diabetes
What education do we teach HIV/AIDS patients?
understand transmission, course of disease, symptoms of opportunistic infections, treatments, and medications
What are some opportunistic infections related to HIV/AIDS?
Pneumocystis carinii pneumonia, CMV, TB, toxoplasmic encephalitis, cryptococcal meningitis, disseminated histoplasmosis, coccidioidomycosis, progressive neuro diseases (HIV associated dementia, CNS lymphoma, and progressive polyradiculopathy)
What is HIV/AIDS?
AIDS is the final stage of HIV
AIDS is a chronic condition
Clinical features of 3rd degree heart block?
slow pulse, confusion, syncope, signs and symptoms of decreased cardiac output (decreased BP, chest pain, SOB, agitation, apathy)
Causes of 3rd degree heart block?
ischemic heart disease, acute MI, conduction system disease
What is the treatment of 3rd degree block?
What happens during 3rd degree heart block?
- atrial and ventricles are blocked-- no communication b/t atria and ventricles
- block can occur in AV node, bundle of His, or bundle branches
What is 1st degree heart block?
impulse originates in SA node and conduction is prolonged in AV node
How does 1st degree present?
PR interval >0.20, always constant and P wave is upright
What medication can cause first degree heart block?
Diagnostics associated with HIV/AIDS?
EIA- antibodies are detected, resulting in positive results and marking the end of the window period
Western blot- also detects antibodies to HIV; used to confirm EIA
Viral load- measures HIV RNA in the plasma
CD4/CD8- markers found on the lymphocytes. HIV kills CD4+ cells, which results in a significantly impaired immune system
