RL is a 54 YOM who’s calculated 10-year atherosclerotic cardiovascular disease (ASCVD) risk is 18 %. Which of the following is the most appropriate pharmacotherapy recommendation for CR?
Answer(s): B
This patient belongs in one of the four statin benefit groups because his estimated 10-year ASCVD risk is over 7.5%. Adults 40 to 75 years of age with LDL–C 70 to 189 mg/dL, with an estimated 10-year ASCVD risk ≥7.5% and without clinical ASCVD or diabetes should receive either a moderate-intensity or high-intensity statin. Since the extent of reducing the risk of ASCVD is proportionally related to the degree of LDL-C reduction, risk could be reduced more so with a high intensity statin. Considering the given options, Atorvastatin 80 mg PO QHS is the best choice.
What is the mEq/ml (Milliequivalents) of 50% Magnesium Sulfate? (Molecular weight of MgSO4 is 120.4g/mol.)
50gm/100ml × 1equiv/120.4gm × 1000meq/1equiv = 4.16meq/ml
All of the following may increase triglycerides except:
Answer(s): C

What is the Osmolarity in mOsm/L of 40mEq of KCl in 100ml sterile water? (Molecular weight of KCl is 74.5gm/ mol.)?
40mEq × 1equiv/1000mEq × 74.5g/1equiv = 2.98 gm of KCl in 100ml. Calculate: mOsm/L. 2.98g/100ml × 1mol/74.5g × 2Osm/1mol × 1000mOsm/ Osm × 1000ml/1L = 800mOsm/L
