A nurse is reviewing the serum laboratory findings for a client who has hypertension and is prescribed hydrochlorothiazide.

Which of the following findings should the nurse report to the provider?.

Potassium 2.3 mEq/L.

Chloride 99 mEq/L.

Sodium 136 mEq/L.

Calcium 10 mg/dL.

Answer and Explanation

The Correct Answer is A

Choice A rationale:
Potassium 2.3 mEq/L is below the normal range of 3.5 to 5.0 mEq/L1. Hydrochlorothiazide, a diuretic, can cause hypokalemia, which is a low level of potassium.
Choice B rationale:
Chloride 99 mEq/L is within the normal range of 96 to 106 mEq/L2, so it’s not a concern.
Choice C rationale:
Sodium 136 mEq/L is within the normal range of 135 to 145 mEq/L3, so it’s not a concern.
Choice D rationale:
Calcium 10 mg/dL is within the normal range of 8.6 to 10.2 mg/dL4, so it’s not a concern.

Correct Answer is B

Explanation

The correct answer is choice B. Inject 20 units of air into the NPH insulin vial.

Choice A rationale:

Replacing the needle for withdrawal with a safety needle is an important step to ensure safety and prevent needle-stick injuries. However, this action is not the first step when mixing two types of insulin. The initial steps involve preparing the insulin vials by injecting air into them.

Choice B rationale:

Injecting 20 units of air into the NPH insulin vial is the correct first step. This is because NPH insulin is a suspension and needs to be mixed properly. Injecting air into the vial helps to equalize the pressure, making it easier to withdraw the correct amount of insulin later. This step is crucial to ensure accurate dosing and proper mixing of the insulin.

Choice C rationale:

Injecting 10 units of air into the regular insulin vial is also necessary, but it is not the first step. The correct sequence is to first inject air into the NPH insulin vial, then into the regular insulin vial. This order helps prevent contamination of the regular insulin with NPH insulin.

Choice D rationale:

Withdrawing 10 units of insulin from the regular insulin vial is an important step, but it should be done after injecting air into both vials. The correct sequence ensures that the insulin is mixed properly and that the doses are accurate.

By following these steps in the correct order, the nurse ensures that the insulin is mixed safely and effectively, minimizing the risk of errors and ensuring proper glycemic control for the patient.

A. Insulin glargine. B. Insulin detemir. C. Regular insulin. D. NPH insulin.

Correct Answer is C

Explanation

Choice A rationale:
Insulin glargine is a long-acting insulin and is not used for the immediate treatment of diabetic ketoacidosis (DKA).
Choice B rationale:
Insulin detemir is also a long-acting insulin and is not used for the immediate treatment of DKA.
Choice C rationale:
Regular insulin is a short-acting insulin and is used for the immediate treatment of DKA.
Choice D rationale:
NPH insulin is an intermediate-acting insulin and is not used for the immediate treatment of DKA.
