Osteoporosis and steroid use | steroids decrease inflammation, but also decrease formation of new bone, increase breakdown of old bone, and decrease absorption of calcium from food by the body |
Parathyroid hormone(PTH) | moves calcium from bone into the blood stream |
When Mg deficit | freq K and Ca deficit |
When Phos deficit | freq rise in Ca |
When Phos increase | freq a reduction in Ca |
Hypercalcemia | excessive production of PTH leads to an elevated calcium level, associated with postmenopausal osteoporosis, Paget disease, and malignancies |
Hypercalcemia & Hyperparathyroidism | N/V, weakness, tx Calcitonin-pushes calcium back into bone |
Hypoparathyroidism | results in low calcium in the blood stream-tetany, tx calcium & vitamin D |
Trousseau’s sign | low calcium, BP cuff around arm for 3min->spasm is + sign for hypocalcemia |
Tetany | involuntary contraction of muscles-trousseau’s/chvostek’s, + signs hypocalcemia |
Chvostek’s sign | hypocalcemia, facial nerve tapped->creates nose/lips twitch + sign |
Type I diabetes mellitus | insulin b/c no insulin production available |
Type II DM | sulfonylurea-glyburide/Diabeta/Micronase-stimulates insulin production, or biquanide-metformin/Glucophage-makes cells more sensitive ton insulin allowing more uptake of glucose |
Insulin-Nursing considerations | assess for contraindications, physical assessment, assess skin, body sx changes, nutritional intake, activity level, blood glucose levels/lab tests |
Sliding Scale/Correction Insulin | given to reduce elevated blood glucose level to a normal range, insulin designed to be given independent of nutritional intake |

Fixed-Combo for HTN | Lotrel(amlodipine w/ benazepril), allows for fewer tablets or capsules each day, making it easier for pt to comply w/ drug therapy, pt stabilized on each drug first then appropriate combo product |
Congestive Heart Failure | inability of heart to circulate blood effectively enough to meet body requirements-less than 55% of blood is ejected from LEFT ventricle during a heartbeat |
digoxin/Lanoxin | cardiac glycoside, a bioavailability drug, narrow window of serum safety(0.5-2.0), also for tx of atrial fib +inotropic effect,-chronotropic effect, assess apical pulse 60sec, SE; h/a, GI upset, anorexia, visual disturbances, fatigue, OD-digiband is antid |
Chronotropic | slows heart down |
Inotropic | beats more effectively |
Preload | amount of blood that is brought back to heart to be pumped around, diuretics reduce preload by diuresis so less blood is brought back to heart to be pumped |
Afterload | resistance against which the heart has to beat-BP measures afterload, CCB and vasodialators decrease afterload because they reduce arterial smooth muscle tone/tension |
arrhythmia | irregularity or loss of rhythm |
dysrhythmia | abnormal, disordered, or disturbed rhythm |
atrial fibrillation | lack of coordinated pumping action, blood is not effectively pumped into the ventricles, blood not pumped out tends to stagnate->stagnated blood tends to clot |

How to treat Angina | nitrates, beta-adrenergic blockers, calcium channel blockers |
Nitrates | M of A-vasodialators decrease BP, take one every 5min, call 911 |
Hyperlipidemia | increase in level of lipids in the blood, caused by; excessive dietary intake of fats, genetic alterations in fat metabolism, cultural variations related to lipid levels |
Hyperlipidemia-Tx | diet, exercise, HMG-CoA reductase inhibitors- atorvastatin(Lipitor), cholesterol absorption inhibitor- ezetimibe(Zetia) |
Statins | Lipitor more risk for liver toxicity than Zocor-yearly LFT, rhabdomyolysis-a breakdown of muscles which can lead to ARF, NO grapefruit-heart arrhythmias/dysrhythmia, benefits of statins for diabetics, take at bedtime, should have tried diet & exercise |
Embolism | clot that travels from where it was formed |
Thrombus | blood clot that forms in a vessel |
aspirin & clopidogrel/Plavix | prevention of platelets from clumping together by inhibiting enzymes and factors that normally lead to arterial clotting, primary prevention of acute MI, prevention of reinfarction, prevention of stroke |
warfarin/Coumadin | atrial fibrillation/status post thrombosis/embolism/artificial heart valves, PT/I NR monitoring, therapeutic range 2-3, ^ GI bleeding, interacts w/ many drugs/supplements, vit K decreases effect of warfarin, antidote vit K |

rivaroxaban/Xarelto | expensive but ins does not want to pay for, DVT, non-valvular afib, bleeding, doesn’t require INR |
heparin | acute tx and prevention of venous thrombosis and pulmonary embolism, must be injected, aPTT/PTT laboratory value monitoring |
dalteparin/Fragmin, enoxaparin/Lovenox | prevention of clots and emboli status post-surgery/prolonged bed rest |
