Atrial natriuretic peptide role in the kidneys - ️️-Increases GFR by altering pressure in the glomerular capillaries -Reduces the reabsorption of sodium in the distal convoluted tubules through inhibition of ADH -Reduces renin secretion, inhibiting the RAAS ◦Result = fluid loss from the extra cellular compartment and lowered blood pressure Body mechanisms for fluid control - ️️-Thirst mechanism: osmoreceptors in the hypothalamus -Antidiuretic hormone (ADH): promotes reabsorptio...

Only Factor X low molecular weight heparin inactivates what? Complaints pts on hyperlipidemic agents muscle aches, flushing, diarrhea, severe pruritis, constipation, rhabdomyolisis, decreased sexual function What is the mechanism of action of heparin? Activates antithrombin III How can Heparin be reversed? Protamine sulfate (reverses heparin quickly) Anti-ischemic agents that converts the myocyte action from fatty acids to glycolysis ... What type of agents can cause muscle pains? Antihyp...

A patient states they have a history of bruising and DVTs. They were taking a drug for this but have now switched to a drug that is safer and doesn't require constant f/u's. What is the drug and what is the mechanism? When did they switch to this drug? Apixaban / selective, reversible inhibitor of factor Xa --> inhibits thrombin-induced platelet aggregation and thrombin generation After INR < 2.0 after taking Coumadin. A patient states they have a history of bruising and DVTs. They w...

ANS-1 final exam questions and answers 2024 In the RAAS, what substance is formed which causes vasoconstriction of the blood vessels? A. Angiotensin converting enzyme B. Renin C. Aldosterone D. Angiotenin II - Answer-D The RAAS system raises BP by 2 mechanisms. ID these mechanisms. SATA A. Increased blood volume (aldosterone) B. Decreased vascular resistance (renin) C. Tachycardia (epinephrine) D. Vasoconstriction (angiotensin II) E. Hypovolemia (ADH) - Answer-A, D When you administ...

Mechanism of anti-HTN meds in the RAAS decreased GFR--> stimulation of renin (anti-renin meds work here)-->angiotensin release-->converts to angio1 -->(ACE inhibitors work here) angio2--> (ARBs work here) aldosterone from adrenals (diuretics work here)= water retention and vasoconstriction in the periph How do Alpha 1 blockers work to treat HTN? Reduces periph vascular resistance and dilation of arteries/veins. Also relaxes smooth muscle in the bladder neck and prostate. Best take...
