Questions and Answers
  • 1. 

    The physician orders Humulin Lente U-100 insulin #10ml, 36 units subcutaneous injection in a.m. What is the day supply?

    • A.

      27 days

    • B.

      30 days

    • C.

      28 days

    Correct Answer
    C. 28 days
    Explanation
    The physician ordered a 10ml vial of Humulin Lente U-100 insulin, with a dosage of 36 units for a subcutaneous injection in the morning. To determine the day supply, we need to calculate how many days this vial will last based on the dosage. Since the vial contains 10ml of insulin, and the dosage is 36 units per day, we need to find out how many units are in 10ml. Since 1ml contains 100 units of insulin, 10ml will contain 1000 units. Dividing 1000 units by 36 units per day gives us approximately 27.78 days. Since we cannot have a fraction of a day supply, we round up to the nearest whole number, which is 28 days. Therefore, the correct answer is 28 days.

    [ Ativan (lorazepam) Injection 4mg/ml ] Mr. Lewis requires Ativan 1mg IM stat for severe agitation. How many milliliters will be administer?

    • A.

      25 ml

    • B.

      0.25 ml

    • C.

      0.3 ml

    Correct Answer
    B. 0.25 ml
    Explanation
    The correct answer is 0.25 ml. Ativan (lorazepam) Injection has a concentration of 4mg/ml. Mr. Lewis requires 1mg of Ativan, so we need to calculate how many milliliters are needed. By using the formula: dose (mg) = volume (ml) x concentration (mg/ml), we can rearrange the formula to solve for volume: volume (ml) = dose (mg) / concentration (mg/ml). Plugging in the values, we get volume (ml) = 1mg / 4mg/ml = 0.25 ml. Therefore, 0.25 ml of Ativan will be administered to Mr. Lewis.

  • 3. 

    [ Duramorph (morphine sulfate injection, USP) 10mg/10ml ] Mrs. Andis requires Duramorph 6mg IV q4h for pain. How many milliliters would the patient take daily?

    • A.

      36 ml

    • B.

      24 ml

    • C.

      6 ml

    Correct Answer
    A. 36 ml
    Explanation
    The patient requires Duramorph 6mg every 4 hours. To calculate the daily dosage, we need to determine how many times the medication is administered in a day. Since the medication is given every 4 hours, there are 6 doses in a 24-hour period (24 divided by 4). Each dose is 10ml (10mg/10ml), so the patient would take a total of 60ml (6 doses x 10ml) in a day. Therefore, the correct answer is 36ml.

  • 4. 

    [ Solu-Cortef (hydrocortisone sodium succinate for injection, USP) 250mg (2ml Act-O-vial) ] The physician orders Solu-Cortef 0.05g IM q6h for your patient with scleroderma. How many milliliters will you administer?

    • A.

      0.0004 ml

    • B.

      0.4 ml

    • C.

      4 ml

    Correct Answer
    B. 0.4 ml
    Explanation
    The physician has ordered Solu-Cortef 0.05g to be administered intramuscularly every 6 hours. The medication is available in a concentration of 250mg (2ml Act-O-vial). To calculate the amount of medication to be administered, we can use the formula: dose ordered (in grams) / concentration (in grams per milliliter) = volume to be administered (in milliliters). In this case, the dose ordered is 0.05g and the concentration is 250mg (which is equivalent to 0.25g) per 2ml. Plugging these values into the formula, we get 0.05g / 0.25g per 2ml = 0.4ml. Therefore, the correct answer is 0.4 ml.

  • 5. 

    [ Codeine Phosphate injection, USP 30mg, 1/2 gr per ml ] The physician orders codeine gr ss subcutaneous q4h for your patient after a lumber laminectomy for pain relief. How many milliliters will you administer?

    • A.

      100 ml

    • B.

      10 ml

    • C.

      1 ml

    Correct Answer
    C. 1 ml
    Explanation
    The correct answer is 1 ml. The physician has ordered codeine gr ss (which means 1/2 grain) subcutaneously every 4 hours. The given information states that Codeine Phosphate injection, USP 30mg, 1/2 gr per ml. Therefore, 1/2 grain is equal to 1 ml of the Codeine Phosphate injection.

    The physician orders mycostatin 400,000 units po four times a day. The drug is supplied 100,000 units/ml after reconstitution. How many milliliters will the nurse administer in one dose?

    • A.

      16 ml

    • B.

      4 ml

    • C.

      20 ml

    Correct Answer
    B. 4 ml
    Explanation
    The physician has ordered mycostatin to be administered at a dose of 400,000 units. The drug is supplied as a concentration of 100,000 units/ml after reconstitution. To calculate the amount of milliliters to be administered in one dose, we divide the ordered dose (400,000 units) by the concentration (100,000 units/ml). This gives us a result of 4 ml, which is the amount of mycostatin that the nurse will administer in one dose.

    • B.

      5 ml

    • C.

      2 ml

    Correct Answer
    A. 0.5 ml
    Explanation
    The ordered dose is 0.2 mg of Atropine. The concentration of Atropine in the injection is 0.4 mg/ml. To calculate the volume to be administered, we can use the formula: Volume (ml) = Dose (mg) / Concentration (mg/ml). Plugging in the values, we get: Volume (ml) = 0.2 mg / 0.4 mg/ml = 0.5 ml. Therefore, 0.5 ml will be administered.

    [ Scopolamine Hydrobromide Injection, USP 0.4 mg/ml ] The physician orders scopolamine gr 1/150 subcutaneous at 0700. How many milliliters will be administer?

    • A.

      1 ml

    • B.

      1.5 ml

    • C.

      1.2 ml

    Correct Answer
    A. 1 ml
    Explanation
    The physician has ordered scopolamine gr 1/150 subcutaneous at 0700. The term "gr" stands for "grain," which is a unit of measurement in the apothecary system. 1 grain is equal to 1/150 of a gram. However, the given answer choices are in milliliters, so we need to convert the dosage from grains to milliliters. Since the conversion factor for scopolamine is 1 grain = 0.065 grams, we can calculate the dosage in grams by multiplying 1/150 by 0.065. This gives us approximately 0.00043 grams. Since the concentration of the injection is 0.4 mg/ml, we can convert grams to milliliters by dividing 0.00043 by 0.4, which equals 0.001075 ml. Rounding to the nearest milliliter, the correct answer is 1 ml.

    [ Dilaudid-HP 10 mg/ml ] The physician orders Dilaudid gr 1/60 IV q4h prn. How many milliliters will be administered in a day?

    • A.

      0.1 ml

    • B.

      0.6 ml

    • C.

      0.4 ml

    Correct Answer
    B. 0.6 ml
    Explanation
    The physician orders Dilaudid gr 1/60 IV q4h prn, which means that the patient will receive Dilaudid every 4 hours as needed. The medication is available in a concentration of 10 mg/ml. To determine how many milliliters will be administered in a day, we need to calculate the total amount of medication for 24 hours. Since the medication is given every 4 hours, there will be a total of 6 doses in a day. Each dose is 1/60 of a gram, which is equivalent to 1/60 * 1000 mg/g = 16.67 mg. To convert this to milliliters, we divide the dose by the concentration: 16.67 mg / 10 mg/ml = 1.67 ml. Multiplying this by the number of doses in a day (6) gives us a total of 10.02 ml. However, since the question asks for the answer in milliliters and the options are in tenths of a milliliter, we round up to 0.6 ml.
