NAPLEX Practice Exam Questions with Answers North American Pharmacist Licensure Examination Certification

The only bile acid sequestrant, colesevelam (Welchol), has been shown to increase triglycerides through mechanism of: activation of phosphatidic acid phosphatase with promotes triglyceride synthesis. GLP-1 agonists work on GLP 1 receptors to increase insulin secretion, decrease glucagon secretion, and increase satiety. Thiazolidinediones activate nuclear transcription factor PPAR gamma to increase insulin sensitivity. SGLT2 inhibitors inhibit glucose reabsorption in the kidney. Alpha-glucosidase inhibitors slow down digestion and absorptions of carbs in the gut.

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.

To determine the dose conversion IV to PO, the ratio of PO to IV needs to be determined, this is 7.5 / 1.5 which is 5. This number means that the PO dose is 5 times more than the IV dose to get the same amount of drug into the bloodstream. If the patient is taking 0.5 mg IV then the PO dose would be 0.5 mg multiplied by 5, which is 2.5 mg. Since the patient is taking the medication every 4 hours the patient is receiving 6 doses, 24hrs/4hrs = 6. Since the patient is receiving 2.5 mg every dose and is receiving 6 doses a day, the patient is receiving 15 mg, 2.5 mg multiplied by 6 doses.

Acarbose is an alpha glucosidase inhibitor that inhibits carbohydrate breakdown. Metformin is a biguanide that decreases hepatic glucose production. Dapagliflozin is a SGLT2 inhibitor to decrease glucose reabsorption in

the kidney. Pioglitazone is a TZD that increases insulin sensitivity. Sitagliptin is a DPP-4 inhibitor that works on incretins/increase insulin secretion/decrease glucagon secretion.

LDL can be elevated by diuretics, cyclosporine, glucocorticoids, and amiodarone.

If 40mg of amoxicillin are needed per kg of body weight, then the dose of amoxicillin is 40mg multiplied by the

patient’s body weight. This patient weighs 18 lbs, based on the conversion of 2.2 lbs = 1 kg, the patient weighs

8.2 kg. 40 mg multiplied by 8.2 kg is equal to 328 mg, this is one dose of amoxicillin. If the amoxicillin comes in 250 mg/5 mL, then it needs to be determined how many mLs it will take to get 328 mg of amoxicillin. In order to do this 328 mg needs to be divided by 250 mg to get a ratio. This comes out to be 1.312. This ratio can be multiplied by the number of mLs it takes to make up 250 mg, which is 5 mLs. 1.312 multiplied by 5 mLs is 6.56 mL, this is how many mLs it will take to have 328 mg. This volume is for 1 single dose of amoxicillin. The patient is receiving 2 doses per day and for a total of 10 days, this means the patient will be receiving 20

doses. 20 doses multiplied by 6.56 mL doses equals the total volume the patient will be receiving, which is

131.2 mL.

Sucralfate is a drug used to treat active duodenal ulcers and may also be used to treat GERD or stress ulcers.

0.9% = 9 grams per every 1,000mL Molecular weight of NaCl = 58.5 9 / 58.5 = 0.154 moles 0.154 moles is the same as 154 millimoles There are 154 millimoles of sodium ions and 154 millimoles of chloride ions in 0.9% sodium chloride.

Pregnancy test. Tetracyclines are effective in the treatment of severe cases of acne. They are however teratogenic. As such, it is imperative to make sure female patients are not pregnant prior to starting this medication. In many instances patients are started on concurrent birth control to mitigate this risk even further.

A chest x-ray (B) is an important exam to obtain prior to starting drugs which have pulmonary toxicity as a side effect such as amiodarone. A complete blood count (C) would be useful prior to starting a medication that causes anemia, such as immunosuppressive and chemotherapeutic agents. Liver function tests (D) are important to establish as a baseline prior to starting anti-mycobacterial agents. Creatine kinase levels (E) are used to establish as a baseline prior to starting statins.

We have 1g of potassium permanganate in 25mL We have 300mL of solution

For every 25mL of that 300mL, we have 1g of KmnO4

300mL must have 12g of potassium permanganate (300ml/25mL)

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.

In the management of acute ischemic stroke, alteplase should be administered within 3 hours of symptom onset.

Non-dihydropyridine calcium channel blockers – which are diltiazem and verapamil – are statistically more likely to cause constipation. Of these two, verapamil has a higher probability of causing this side effect.

Agents that can cause elevated triglycerides: oral estrogens, glucocorticoids, bile acid sequestrants, protease inhibitors, retinoic acid, anabolic steroids, sirolimus, raloxifene, tamoxifen, beta blockers (not carvedilol), and thiazides.
