A nurse is preparing to administer insulin to a client who has type 1 diabetes mellitus. Which of the following actions by the nurse demonstrates proper technique for mixing regular and NPH insulin in the same syringe?

A) Incorrect. The nurse should inject air into the regular vial first, then into the NPH vial. This can prevent contamination of the regular insulin with NPH insulin and ensure accurate dosing.

B) Correct. The nurse should draw up regular insulin first, then NPH insulin. This can prevent contamination of the regular insulin with NPH insulin and ensure accurate dosing. Regular insulin is clear and NPH insulin is cloudy.

C) Correct. The nurse should roll the NPH vial between their palms before drawing up insulin. This can resuspend the insulin particles that may have settled at the bottom of the vial and ensure uniform concentration.

D) Correct. The nurse should wipe the rubber stoppers of both vials with alcohol swabs before inserting needles. This can reduce the risk of infection and contamination.

C) Incorrect. The client should avoid taking their medication with grapefruit juice as it can interfere with the metabolism of some antihypertensive drugs and increase the risk of adverse effects.

A) Correct. The client should not stop taking their medication even if they feel better as this can cause a rebound increase in blood pressure and worsen their condition.

B) Correct. The client should check their blood pressure regularly and record the readings to monitor their response to treatment and identify any changes that may require adjustment of their medication dose.

D) Correct. The client should inform their doctor if they experience any side effects from their medication such as dizziness, headache, fatigue, or cough, as these may indicate a need for a different drug or a lower dose.
