A nurse is preparing to mix NPH insulin and regular insulin for administration.
Which of the following actions should the nurse take?
Use a tuberculin syringe.
Inject air into each vial.
Withdraw the NPH insulin first.
Shake the regular insulin vial.
The Correct Answer is B
Choice A rationale:
While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.
Choice B rationale:
Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.
Choice C rationale:
Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.
Choice D rationale:
Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.

Correct Answer is B
Explanation
Choice A rationale:
A urine output of 600 mL in 8 hours is within the normal range. The average urine output for adults is about 1 to 2 liters per day.
Choice B rationale:
Clonidine is an antihypertensive medication. If the client’s blood pressure is already low (88/50 mm Hg), administering clonidine could further lower the blood pressure and cause hypotension.
Choice C rationale:
A heart rate of 110/min is slightly high, but it’s not a direct indication to withhold clonidine. Clonidine can actually help lower an elevated heart rate by reducing the levels of certain chemicals in your blood.
Choice D rationale:
A blood glucose level of 70 mg/dL is at the lower end of the normal range (70-100 mg/dL) However, clonidine does not directly affect blood glucose levels, so this would not be a reason to withhold the medication.
Correct Answer is B
Explanation
Choice A rationale:
Ketorolac is a non-steroidal anti-inflammatory drug (NSAID) used for pain relief after surgery. However, it’s not typically administered every 3 hours. Overuse can lead to serious side effects.
Choice B rationale:
If the client’s pain level remains high after receiving ketorolac, administering an opioid medication like oxycodone may be appropriate.
Choice C rationale:
While acetaminophen can be used for pain relief, rectal administration is not typically the first choice for postoperative pain management.
Choice D rationale:
It’s inappropriate to label a patient as exhibiting drug-seeking behaviors simply because their reported pain level remains high after medication. Pain is subjective and should be addressed appropriately.
