A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?
400 gt/min
6 gt/min
25 gt/min
9 gt/min
The Correct Answer is C
The gt/min is 25.
This answer is correct because it is based on a simple formula and calculation. The nurse should use the following formula to calculate the gt/min:
gt/min = (Volume in mL x Drop factor in gt/mL) / Time in min
Plugging in the given values, the nurse should get:
gt/min = (100 mL x 15 gt/mL) / 60 min
gt/min = 25
Therefore, the gt/min is 25.

Correct Answer is D
Explanation
The nurse should administer 0.5 mL to the patient.
This answer is correct because it is based on a simple ratio and proportion calculation. The nurse can set up a proportion as follows:
2 mg / 1 mL = 1 mg / x mL
Cross-multiplying and solving for x gives:
x = 0.5 mL
Therefore, the nurse should administer 0.5 mL of Stadol injection to deliver 1 mg of the medication to the patient.
Correct Answer is B
Explanation
To find the dose of ondansetron, you need to use the formula for weight-based dosage calculation:
Dose (mg) = Weight (kg) x Prescribed dose (mg/kg)
Since the client's weight is 70 kg and the prescribed dose is 0.34 mg/kg, plug in these values into the formula:
Dose (mg) = 70 kg x 0.34 mg/kg
Simplify and solve for the dose:
Dose (mg) = 23.8 mg
Therefore, the client should receive **23.8 mg** of ondansetron prior to chemotherapy.
