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 V 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.)

Full Explanation
To calculate the manual IV flow rate in drops per minute (gtt/min), you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused in mL / Time in minutes) * Drop factor (gtt/mL)
Given:
- Volume to be infused = 250 mL
- Time in minutes = 30 minutes
- Drop factor = 10 gtt/mL
Now, plug these values into the formula:
Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL
Flow rate (gtt/min) = (8.33) * 10
Flow rate (gtt/min) ≈ 83.3
Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.

A nurse is preparing to administer amoxicillin 775 mg PO. Available is amoxicillin oral suspension 400 mg/5 mL. How many ml should the c administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)
Full Explanation
To calculate the volume in milliliters (mL) of amoxicillin oral suspension needed to administer 775 mg, you can use the following formula:
Volume (mL) = (Desired dose in mg / Concentration in mg/mL)
Given:
- Desired dose = 775 mg
- Concentration = 400 mg/5 mL
First, calculate the concentration in mg/mL by dividing 400 mg by 5 mL:
Concentration = 400 mg / 5 mL = 80 mg/mL
Now, use the formula to calculate the volume in mL:
Volume (mL) = (775 mg / 80 mg/mL)
Volume (mL) ≈ 9.69 mL
Rounded to the nearest whole number, the nurse should administer approximately 10 mL of amoxicillin oral suspension to provide a dose of 775 mg.
A nurse is reviewing medications prescribed for a client. For which of the following prescriptions should the nurse contact the provider for clarification?
A. Docusate sodium 200 mg PO at bedtime
This prescription is appropriate for a stool softener (Docusate sodium) commonly used to prevent or treat constipation. It's a standard dosage and administration for this type of medication and doesn't require further clarification.
B. Meloxicam 15 mg PO daily
Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used for pain and inflammation. This prescription indicates a standard dosage and administration for this medication and doesn't require further clarification.
C. Regular insulin 8 units subcutaneous before meals
Regular insulin 8 units subcutaneous before meals is a vague and potentially dangerous prescription. The dose of insulin should be individualized based on the client's blood glucose level, carbohydrate intake, and activity level. A prescription for "before meals" without a sliding scale or specific blood glucose parameters is incomplete and potentially dangerous The nurse should contact the provider for clarification on how to adjust the dose according to the client's needs.
D. Fentanyl 25 mcg/hr transdermal patch
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.
E. None
None
F. None
None

A nurse is preparing to administer 0.45% sodium chloride 2.5 L IV to infuse over 24 hr. How many ml. should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Full Explanation
Since the total volume is 2.5 L and you need to administer it over 24 hours, the total amount to be administered is simply the entire volume.
- Total volume to administer: 2.5 L
- Convert to milliliters (mL): 2.5 L = 2,500 mL
So, the nurse should administer 2,500 mL over 24 hours.
