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 C
Explanation
Choice Arationale:
The statement about taking the medication with food is incorrect. Nitroglycerin sublingual tablets should not be taken with food. They work much faster when absorbed through the lining of the mouth.
Choice B rationale:
The statement that the medication can slow the heart rate is incorrect. Nitroglycerin does not slow the heart rate. In fact, it can cause a reflex tachycardia, where the heart rate increases.
Choice C rationale:
The statement that the effects of the medication should be felt within 5 minutes is correct. This indicates an understanding of the instructions.
Choice Drationale:
Taking the medication every 10 minutes until the pain goes away is incorrect. Nitroglycerin sublingual tablets usually give relief in 1 to 5 minutes. However, if the pain is not relieved, a second tablet can be taken 5 minutes after the first tablet. If the pain continues for another 5 minutes, a third tablet may be used. Taking the medication every 10 minutes could lead to an overdose.
Correct Answer is ["1.2"]
Explanation
To calculate the dose of somatropin to be administered per dose, we first need to convert the child's weight from pounds to kilograms. We can do this using the following conversion factor:
1 kg = 2.2 lbs
Therefore, the child's weight in kilograms is:
weight_kg = 66 lbs / 2.2 lbs/kg = 30 kg
Next, we can calculate the total dose of somatropin to be administered per week using the following formula:
total_dose = weight_kg * 0.24 mg/kg/week
This gives us a total dose of:
total_dose = 30 kg * 0.24 mg/kg/week = 7.2 mg/week
Finally, we can calculate the dose of somatropin to be administered per dose by dividing the total dose by the number of daily doses:
dose_per_dose = total_dose / 6 doses/day = 1.2 mg/dose
Therefore, the nurse should administer 1.2 mg of somatropin per dose.
Answer: 1.2 mg of somatropin per dose.
