A nurse is mixing regular insulin and NPH insulin in the same syringe prior to administering it to a client who has diabetes mellitus.
Which of the following actions should the nurse take first?
Inject air into the NPH vial.
Withdraw the NPH insulin from the vial.
Withdraw the regular insulin from the vial.
Inject air into the regular insulin vial.
The Correct Answer is A
The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:
-
Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
-
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
-
Withdraw the regular insulin from the vial : The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
-
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.
This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Correct Answer is C
Explanation
Methimazole is an antithyroid medication that blocks the thyroid from making thyroid hormones. It is used to treat hyperthyroidism caused by Graves’ disease, which is an autoimmune disorder that stimulates the thyroid gland to produce excess hormones. After taking methimazole for 2 months, the client should expect to see a reduction in the symptoms of hyperthyroidism, such as weight loss, increased pulse rate, and heat intolerance. Increased sleeping is a sign of improved thyroid function, as hyperthyroidism can cause insomnia and restlessness.
Choice A is wrong because weight loss is a symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should lower the thyroid hormone levels and help the client gain weight.
Choice B is wrong because an increase in pulse rate is also a symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should lower the heart rate and blood pressure by reducing thyroid hormone levels.
Choice D is wrong because warmer skin is another symptom of hyperthyroidism, not a result of methimazole treatment. Methimazole should improve the client’s heat tolerance and make the skin cooler and less sweaty.
Correct Answer is A
Explanation
The FACES pain scale is a self-report tool that uses six facial expressions to indicate different levels of pain. It is suitable for children aged 3 to 13 years who can match their pain to a face. The nurse should use this scale to assess the pain of a 4-year-old child following an orthopaedic procedure.
Choice B. Word-graphic is wrong because it is a pain scale that uses words and pictures to describe pain intensity.
It is suitable for children aged 8 to 17 years who can read and understand words.
Choice C. Numeric is wrong because it is a pain scale that uses numbers from 0 to 10 to rate pain intensity. It is suitable for children aged 5 years and older who can understand numbers and concepts of more or less.
Choice D. CRIES is wrong because it is a pain scale that uses five behavioural indicators (crying, requiring increased oxygen, increased vital signs, expression, and sleeplessness) to measure pain in neonates.
It is suitable for infants aged 0 to 6 months who cannot communicate verbally.
