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.

Answer and Explanation

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 A rationale:

The first dose of the varicella vaccine is usually given when the child is between 12 to 15 months old, not after 3 years.

Choice B rationale:

Aspirin should not be given to children due to the risk of Reye’s syndrome. This syndrome is a rare but serious condition that causes swelling in the liver and brain.

Choice C rationale:

The varicella vaccine should be avoided in children who have leukemia or any other condition that weakens the immune system.

Choice D rationale:

The varicella vaccine is not contraindicated for children who are allergic to eggs. It’s some other vaccines like influenza that have this restriction.

A. Inject the medication at least 5 cm (2 in) from the umbilicus. B. Use the Z-track technique to administer the medication. C. Give the medication without aspirating prior to injection. D. Administer the medication with a 27-gauge '/,-inch needle.

Correct Answer is B

Explanation

Choice A rationale:

Injecting the medication at least 5 cm (2 in) from the umbilicus is not a standard guideline for IM injections. The site of injection depends on factors such as the volume of medication and patient’s age and muscle mass.

Choice B rationale:

Using the Z-track technique to administer the medication is correct. This technique helps to seal the medication in muscle tissue, reducing leakage into subcutaneous tissue.

Choice C rationale:

Giving the medication without aspirating prior to injection is not recommended. Aspiration ensures that the needle is not in a blood vessel before injecting.

Choice D rationale:

Administering the medication with a 27-gauge '/,-inch needle may not be appropriate for an IM injection, especially for adults. A longer and larger gauge needle is typically used for IM injections.
