A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus. Which of the following actions should the nurse take?

Shake both insulin vials for 2 min before withdrawing the doses.

Administer the mixture within 5 min of preparing it.

Withdraw the NPH insulin before the regular insulin.

Inject air into the regular insulin vial before injecting air into the NPH vial.

Answer and Explanation

The Correct Answer is D

A. Shake both insulin vials for 2 min before withdrawing the doses. Insulin vials should never be shaken, as this can create air bubbles and affect dosage accuracy. NPH insulin should be gently rolled between the hands to mix.
B. Administer the mixture within 5 min of preparing it. While insulin should be administered promptly, there is no strict 5-minute requirement.
C. Withdraw the NPH insulin before the regular insulin. Regular insulin should be drawn up first to prevent contamination with the cloudy NPH insulin.
D. Inject air into the regular insulin vial before injecting air into the NPH vial. Air should be injected into the regular insulin first, then into the NPH insulin vial, before withdrawing the doses in the correct order.

Correct Answer is B

Explanation

A. Schedule the client for an MRI after the procedure. This is incorrect because an MRI is not required following a thoracentesis. Instead, a chest X-ray may be ordered to assess for complications such as a pneumothorax.
B. Place the client leaning forward over the overbed table. This is correct because this position allows for optimal lung expansion and easier access to the pleural space for fluid removal.
C. Encourage the client to take deep breaths during the procedure. This is incorrect because the client should remain still and avoid deep breathing or coughing to prevent lung injury.
D. Ensure the client has been NPO for 6 hr. This is incorrect because NPO status is not required for a thoracentesis, as it is not a gastrointestinal or sedation-based procedure.

A. A client who had dialysis and is using an arteriovenous shunt in the left lower forearm B. A client who had a right hemisphere stroke C. A client who has a right peripherally inserted central catheter D. A client who had blood drawn from the right antecubital area 1 hr ago

Correct Answer is C

Explanation

A. A client who had dialysis and is using an arteriovenous shunt in the left lower forearm. This is incorrect because the arteriovenous shunt is in the lower forearm, not the upper arm where blood pressure is measured. The right arm can still be used.
B. A client who had a right hemisphere stroke. This is incorrect because a stroke does not necessarily contraindicate blood pressure measurement on the affected side unless there are complications such as edema or weakness.
C. A client who has a right peripherally inserted central catheter. This is correct because taking a blood pressure on the same side as a peripherally inserted central catheter (PICC) can cause pressure that may damage the catheter or affect its function. The left arm should be used instead.
D. A client who had blood drawn from the right antecubital area 1 hr ago. This is incorrect because drawing blood from an arm does not contraindicate blood pressure measurement in that arm after a short period.
