1. A patient requires 8 mg of morphine IV. Morphine is available as 20 mg/mL. how many mls will you draw up?
a. 0.4 mL
b. 1.6 mL
c. 0.8 mL
d. 1.2 mL
Answer: a. 0.4 mL
Description:To calculate the amount of morphine to draw up, you can use the formula: Amount (mL) = Required Dose (mg) / Concentration (mg/mL) Given that the required dose is 8 mg and the concentration of morphine is 20 mg/mL: Amount (mL) = 8 mg / 20 mg/mL Amount (mL) = 0.4 mL
2. Physician’s order reads; Eltroxin 60 mcg po daily. Available dose: Eltroxin 0.12 mg/mL. How may tablets will you administer?
a. 5 tabs
b. ½ tab
c. ¼ tab
d. 2 tabs
Answer: b. ½ tab
Description:To calculate the number of tablets to administer, you need to convert the physician's order from micrograms (mcg) to milligrams (mg) and then divide by the available dose of the tablets. Given that Eltroxin is available as 0.12 mg/mL and the physician's order is for 60 mcg (micrograms): 1 mg = 1000 mcg, so 0.12 mg = 0.12 * 1000 mcg = 120 mcg Now, you can calculate the number of tablets: Number of tablets = Required Dose (mcg) / Available Dose (mcg/tablet) Number of tablets = 60 mcg / 120 mcg/tablet Number of tablets = 0.5 tablets
3. A patient must 30 units of Humulin regular insulin. The label reads 100 units = 1 mL. How many milliliters should the nurse administer?
a. 0.5 mL
b. 0.3 mL
c. 0.2 mL
d. 1.0 mL
Answer: b. 0.3 mL
Description:To calculate the number of milliliters of Humulin regular insulin to administer, you can use the provided label information: 100 units = 1 mL Given that the patient needs 30 units: Milliliters to administer = Units needed / Units per mL Milliliters to administer = 30 units / 100 units/mL Milliliters to administer = 0.3 mL
4. The physician’s order reads “Administer 1 g cefotaxime is 150 mL of normal saline solution in 60 minutesâ€. What is the flow rate if the drop factors is 20 gtt = 1 mL?
a. 25 gtt/min
b. 72 gtt/min
c. 50 gtt/min
d. 38 gtt/min
Answer: c. 50 gtt/min
Description:To calculate the flow rate in drops per minute (gtt/min), you can use the formula: Flow Rate (gtt/min) = (Volume to be infused in gtt) / Time in minutes Given that the order is to administer 1 g of cefotaxime in 150 mL of normal saline solution over 60 minutes, and the drop factor is 20 gtt = 1 mL: Volume to be infused in gtt = Volume in mL * Drop factor Volume to be infused in gtt = 150 mL * 20 gtt/mL Volume to be infused in gtt = 3000 gtt Now you can calculate the flow rate: Flow Rate (gtt/min) = 3000 gtt / 60 min Flow Rate (gtt/min) = 50 gtt/min
5. Physician’s order-streptomycin 25 mg/kg IM q 12 hr; Available dose; Streptomycin 0.35 Gm/mL. How many ml will you administer for each dose to a 70 kg patient?
a. 2 mL
b. 5 mL
c. 7 ml
d. 10 mL
Answer: b. 5 mL
Description:To calculate the amount of streptomycin to administer for each dose to a 70 kg patient, you can follow these steps: Calculate the total dose required: Total Dose = Dose per kg * Patient's weight Total Dose = 25 mg/kg * 70 kg Total Dose = 1750 mg Convert the total dose to milligrams (since the available dose of streptomycin is given in grams): Total Dose in mg = Total Dose in grams * 1000 mg/g Total Dose in mg = 1.75 g * 1000 mg/g Total Dose in mg = 1750 mg Calculate the volume (ml) of streptomycin solution needed using the available dose: Volume (ml) = Total Dose in mg / Concentration (mg/ml) Volume (ml) = 1750 mg / 0.35 mg/ml Volume (ml) = 5000 ml

Description:To calculate the IV flow rate in drops per minute (gtt/min) for infusing 100 mL over 1 hour using a drop factor of 20 gtt/mL, you can follow these steps: Convert the time to minutes: 1 hour * 60 min/hour = 60 min Calculate the total number of drops needed: Total Drops = Volume to be infused (mL) * Drop factor (gtt/mL) Total Drops = 100 mL * 20 gtt/mL Total Drops = 2000 gtt Calculate the flow rate: Flow Rate (gtt/min) = Total Drops / Time in minutes Flow Rate (gtt/min) = 2000 gtt / 60 min Flow Rate (gtt/min) = 33.33 gtt/min
10. The division of bacterial cells and the exponential increase in their number are indicative of which phase?
a. Lag phase
b. Stationary phase
c. Phase of decline
d. Logarithmic phase
Answer: d. Logarithmic phase
Description:During the logarithmic (also known as exponential or log) phase of bacterial growth, the population of bacteria experiences rapid and exponential growth. This is the phase where bacterial cells are actively dividing and the population is increasing at its maximum rate. The conditions are favorable for growth, and the rate of cell division exceeds the rate of cell death.
