A nurse is preparing to mix NPH insulin and regular insulin for administration.
Which of the following actions should the nurse take?

A.

Use a tuberculin syringe.

B.

Inject air into each vial.

C.

Withdraw the NPH insulin first.

D.

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 A

Explanation

Choice A rationale:

Wheezing can be a sign of an allergic reaction to amoxicillin. It indicates that there may be constriction or inflammation in the airways, which can occur in an allergic reaction.

Choice B rationale:

Bradycardia, or a slower than normal heart rate, isn’t typically associated with an allergic reaction to amoxicillin.

Choice C rationale:

Polyuria, or excessive urination, isn’t typically a sign of an allergic reaction to amoxicillin.

Choice D rationale:

Bruising isn’t typically associated with an allergic reaction to amoxicillin. It could be related to other conditions or medications.

Correct Answer is D

Explanation

Choice A rationale:

While reminding the client to change positions slowly is important to prevent orthostatic hypotension, it is not the priority before administering furosemide.

Choice B rationale:

Preparing the client’s medication is an important step, but it should be done after reviewing the client’s electrolyte levels.

Choice C rationale:

Recording the client’s urinary output is important when administering furosemide, a diuretic, but it is not the priority action.

Choice D rationale:

Reviewing the client’s electrolyte levels is crucial before administering furosemide because it can cause electrolyte imbalances, including low potassium levels, which can lead to serious cardiac complications.
