You need 51.3 mEq of NaCl to make 1/3 NS 1 liter bag. How many ml of 23.4% NaCl would you need? (Molecular weight of Na is 23 and Cl is 35.5)
Answer(s): A
1mEq NaCl= 58.5; Valence = 1. mg = mEq × molecular weight / valence. mg = 51.3mEq × 58.5mg / 1 = 3001.05mg = 3g. 23.4 g/100ml = 3g/Xml X = 12.825mL

Which of the following is considered first-line therapy for reducing the risk of atherosclerotic cardiovascular disease (ASCVD)?
ATP4 found that the use of statins for prevention of ASCVD is extensive and consistent. Statin therapy is recommended for patients at a higher risk of ASCVD who are most likely to experience a net benefit in terms of the potential for risk reduction vs the potential for adverse effects. Non-statin therapies do not provide sufficient benefits in the reduction of ASCVD risk in regards to their potential for adverse effects.
If you mix 30 gm 5% lidocaine cream and 90gm of 0.5% hydrocortisone cream, what percent of lidocaine and hydrocortisone do you have as the end product?
Answer(s): E
Lidocaine: 30g × 0.05 = 1.5g. Hydrocortisone: 90g × 0.005 = 0.45g. 90g + 30g = 120g. 1.5g/120g = 0.0125 × 100 = 1.25% Lidocaine. 0.45g/120g = 0.00375 × 100 = 0.375% Hydrocortisone.
