Question 1:
A nurse is reviewing medications prescribed for a client. For which of the
following prescriptions should the nurse contact the provider for clarification?
A. Fentanyl 25 mcg/hr transdermal patch
B. Meloxicam 15 mg PO daily
C. Regular insulin 8 units subcutaneous before meals
D. Docusate sodium 200 mg PO at bedtime
Explanation
Correct Answer: C
Fentanyl patches are commonly used for chronic pain management. A dose of 25
mcg/hr is within the standard dosing range for patients who are opioid-tolerant. No
clarification is typically needed for this prescription.
Meloxicam 15 mg PO daily:Meloxicam is a nonsteroidal anti-inflammatory drug
(NSAID) used for pain and inflammation.
This prescription is straightforward and commonly used. It is a standard dosage for
meloxicam. However, the nurse should still ensure that the patient does not have any
contraindications or allergies to NSAIDs.
Regular insulin 8 units subcutaneous before meals is a vague and potentially
dangerous prescription. Regular insulin is a short-acting insulin that lowers blood
glucose levels by facilitating the uptake of glucose into the cells. The dose of insulin
should be individualized based on the client's blood glucose level, carbohydrate
intake, and activity level. The nurse should contact the provider for clarification on how
to adjust the dose according to the client's needs.

Docusate sodium 200 mg PO at bedtime:Docusate sodium is a stool softener used to
prevent or treat constipation.This prescription is a standard and commonly used
dosage for docusate sodium. However, as with any medication, the nurse should
assess the patient's specific needs and medical history, ensuring that there are no
contraindications or allergies to this medication.

Question 2:
1. A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three
divided doses to a client who weighs 85 kg. The amount available is
tobramycin 40 mg/mL. How many mL should the nurse administer per
dose? (Round the answer to the nearest tenth. Use a leading zero if it
applies. Do not use a trailing zero.)
Explanation
Correct Answer: 2.1ml
To calculate the dosage of tobramycin for a client who weighs 85 kg, the nurse
should first determine the total daily dose by multiplying the weight by the
prescribed dose per kg.
This gives 3 mg/kg/day x 85 kg = 255 mg/day.
Next, the nurse should divide the total daily dose by the number of doses per
day to get the dose per administration.
This gives 255 mg/day / 3 doses/day = 85 mg/dose.
Finally, the nurse should use the formula D/H x Q to find the volume to be
administered, where D is the desired dose, H is the dose on hand, and Q is the

quantity on hand.
This gives 85 mg/dose / 40 mg/mL x 1 mL = 2.125 mL/dose.
Therefore, the nurse should administer 2.1 mL of tobramycin per dose to the
client.

Question 3:
1. A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in
0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual
IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate to
deliver how many gtt/min? (Round the answer to the nearest whole
number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 83gtt\/min
To calculate the manual IV flow rate, the nurse needs to use the following
formula:
Flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Flow rate (gtt/min) = 250 mL x 10 gtt/mL / 30 min
Flow rate (gtt/min) = 2500 gtt / 30 min
Flow rate (gtt/min) = 83.33 gtt/min

Question 4:
1. A nurse is preparing to administer fentanyl 0.5 mcg/kg via IV bolus to a
client who weighs 187 lb. Available is fentanyl 50 mcg/mL. How many mL
should the nurse administer? (Round the answer to the nearest tenth. Use
a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 0.9
To calculate the dose of fentanyl for a client who weighs 187 lb, the nurse needs
to convert the weight to kilograms and multiply it by the prescribed dose of 0.5
mcg/kg.
One kilogram is equal to 2.2 lb, so the client's weight in kilograms is .2 =
85 kg.
The dose of fentanyl in micrograms is 85 x 0.5 = 42.5 mcg.
The nurse then needs to divide the dose in micrograms by the concentration of
fentanyl in the available solution, which is 50 mcg/mL.
The volume of fentanyl in milliliters is 42. = 0.85 mL.
The nurse should round the answer to the nearest tenth, so the final answer is
0.9 mL.

Correct Answer: C
Fentanyl patches are commonly used for chronic pain management. A dose of 25
mcg/hr is within the standard dosing range for patients who are opioid-tolerant. No
clarification is typically needed for this prescription.
Meloxicam 15 mg PO daily:Meloxicam is a nonsteroidal anti-inflammatory drug
(NSAID) used for pain and inflammation.
This prescription is straightforward and commonly used. It is a standard dosage for
meloxicam. However, the nurse should still ensure that the patient does not have any
contraindications or allergies to NSAIDs.
Regular insulin 8 units subcutaneous before meals is a vague and potentially
dangerous prescription. Regular insulin is a short-acting insulin that lowers blood
glucose levels by facilitating the uptake of glucose into the cells. The dose of insulin
should be individualized based on the client's blood glucose level, carbohydrate
intake, and activity level. The nurse should contact the provider for clarification on how

1. A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three
divided doses to a client who weighs 85 kg. The amount available is
tobramycin 40 mg/mL. How many mL should the nurse administer per
dose? (Round the answer to the nearest tenth. Use a leading zero if it
applies. Do not use a trailing zero.)
Explanation
Correct Answer: 2.1ml
To calculate the dosage of tobramycin for a client who weighs 85 kg, the nurse
should first determine the total daily dose by multiplying the weight by the
prescribed dose per kg.
This gives 3 mg/kg/day x 85 kg = 255 mg/day.
Next, the nurse should divide the total daily dose by the number of doses per
day to get the dose per administration.
This gives 255 mg/day / 3 doses/day = 85 mg/dose.
Finally, the nurse should use the formula D/H x Q to find the volume to be
administered, where D is the desired dose, H is the dose on hand, and Q is the

This gives 85 mg/dose / 40 mg/mL x 1 mL = 2.125 mL/dose.
Therefore, the nurse should administer 2.1 mL of tobramycin per dose to the
client.

Question 3:
1. A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in
0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual
IV tubing is 10 gtt/mL. The nurse should set the manual IV flow rate to
deliver how many gtt/min? (Round the answer to the nearest whole
number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 83gtt\/min
To calculate the manual IV flow rate, the nurse needs to use the following
formula:
Flow rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)
Plugging in the given values, we get:
Flow rate (gtt/min) = 250 mL x 10 gtt/mL / 30 min
Flow rate (gtt/min) = 2500 gtt / 30 min
Flow rate (gtt/min) = 83.33 gtt/min

Question 4:
1. A nurse is preparing to administer fentanyl 0.5 mcg/kg via IV bolus to a
client who weighs 187 lb. Available is fentanyl 50 mcg/mL. How many mL
should the nurse administer? (Round the answer to the nearest tenth. Use
a leading zero if it applies. Do not use a trailing zero.)
Explanation
Correct Answer: 0.9
To calculate the dose of fentanyl for a client who weighs 187 lb, the nurse needs
to convert the weight to kilograms and multiply it by the prescribed dose of 0.5
mcg/kg.
One kilogram is equal to 2.2 lb, so the client's weight in kilograms is .2 =
85 kg.
The dose of fentanyl in micrograms is 85 x 0.5 = 42.5 mcg.
The nurse then needs to divide the dose in micrograms by the concentration of
fentanyl in the available solution, which is 50 mcg/mL.
The volume of fentanyl in milliliters is 42. = 0.85 mL.
The nurse should round the answer to the nearest tenth, so the final answer is
0.9 mL.
