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)

  1. 12.82ml
  2. 16.82ml
  3. 23.4ml
  4. 58.5ml
  5. 10ml

Answer(s): A

Explanation:

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

  1. Hypothyroidism
  2. Vitamin D deficiency
  3. Renal impairment
  4. Hepatic dysfunction

Which of the following is considered first-line therapy for reducing the risk of atherosclerotic cardiovascular disease (ASCVD)?

  1. HMG Co-A reductase inhibitors
  2. Bile acid resins
  3. Nicotinic Acid
  4. Fibrates
  5. Fish oil

Answer(s): A

Explanation:

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?

  1. Lidocaine/Hydrocortisone 2%/1.25%
  2. Lidocaine/Hydrocortisone 0.375%/0.15%
  3. Lidocaine/Hydrocortisone 1.25 %/ 0.15%
  4. Lidocaine/Hydrocortisone 2% /0.25%
  5. Lidocaine/Hydrocortisone 1.25% /0.375%

Answer(s): E

Explanation:

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.
