A nurse has to administer 8 mg of ondansetron to a client before chemotherapy. A 2 mg/mL multi-dose vial is on hand.
How many mL should be administered to this patient?
6 mL
8 mL
2 mL
4 mL
The Correct Answer is D
The nurse should administer 4 mL to this 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 = 8 mg / x mL
Cross-multiplying and solving for x gives:
x = 4 mL
Therefore, the nurse should administer 4 mL of ondansetron to deliver 8 mg of the medication to the patient.

Correct Answer is B
Explanation
One fluid ounce is equal to **29.57353 milliliters**¹²³. To convert fluid ounces to milliliters, you can multiply the value in fluid ounces by 29.57353. For example, 1 fluid ounce x 29.57353 milliliters = 29.57353 milliliters.
Therefore, to convert 100 fl oz of fluids to milliliters, you can multiply 100 by 29.57353. The answer is
**2957.353 milliliters**. This is the amount of fluids that the nurse should provide to the client with renal calculi.
The other options are not correct because they do not match the calculated amount of fluids that the client needs. Option a is wrong because it is too litle fluids, which could result in dehydration or inadequate flushing of the urinary tract. Option c is wrong because it is too much fluids, which could result in fluid overload or electrolyte imbalance. Option d is wrong because it is not a volume but a frequency, and it is also too litle fluids for the client's condition.
Correct Answer is B
Explanation
The correct angle for giving an intradermal injection is **10 to 15 degrees**. This angle allows the needle to enter the dermis, which is the layer of skin just below the epidermis. The needle should be inserted almost flat against the patient's skin, with the bevel side up. A small blister or bleb should form under the skin after injecting the medication.
