A client with diabetic ketoacidosis (DKA) is receiving regular insulin. Which action should the practical nurse (PN) implement to evaluate the effectiveness of the insulin dosage?
Smell the client's breath for resolution of a fruity odor.
Determine the client's orientation to time and space.
Measure the client's urinary output for an increased volume.
Check fingerstick blood glucose for a decrease in the level.
The Correct Answer is D
Regular insulin is the medication of choice for treating DKA. Its main action is to lower blood glucose levels by promoting the uptake of glucose into cells and inhibiting the production of glucose by the liver. Therefore, checking the fingerstick blood glucose level is an important indicator of the effectiveness of the insulin treatment.
A decrease in the blood glucose level indicates that the insulin is working to lower the high blood sugar associated with DKA. This measurement helps the PN assess the response to treatment and adjust the insulin dosage if necessary.
The other actions mentioned are also important assessments in the care of a client with DKA, but they do not specifically evaluate the effectiveness of the insulin dosage:
A. Smelling the client's breath for resolution of a fruity odor is important as it indicates a decrease in ketone production, which is a marker of improving DKA. However, it does not directly evaluate the effectiveness of the insulin dosage.
B. Determining the client's orientation to time and space is part of assessing their neurological status, which is crucial in managing DKA. However, it does not specifically assess the effectiveness of the insulin dosage.
C. Measuring the client's urinary output for an increased volume is important to monitor hydration status and renal function, but it does not directly evaluate the effectiveness of the insulin dosage.

Correct Answer is A
Explanation
A. Gather the procedure tray and equipment – The practical nurse should gather all necessary supplies for the healthcare provider to perform the thoracentesis efficiently. Preparing the equipment beforehand ensures that the procedure can start promptly and reduces interruptions for missing supplies.
Rationale for Incorrect Answers:
B. Cleanse the site and cover with a sterile towel – This action should be performed by the healthcare provider immediately before the procedure to maintain sterility. The PN’s role is to prepare equipment and ensure the client is positioned correctly.
C. Keep the patient NPO (nothing by mouth) and encourage them to void – While voiding may be encouraged before some procedures to improve client comfort, it is not necessary for thoracentesis. Additionally, keeping the client NPO is not required, as the procedure does not typically involve sedation that would necessitate this restriction.
D. Place the patient in an orthopneic position – This may be done just before the procedure, but the healthcare provider typically directs the final positioning. Initial positioning or seating at the bedside can be done, but orthopneic positioning should follow the provider’s instructions.
Correct Answer is B, A, C, D
Explanation
The correct sequence for the interventions when caring for a client with a tracheostomy tube, after donning sterile gloves, is as follows:
Hyperoxygenate with a bag valve mask (BVM) using a nondominant hand. Insert sterile suction catheter in tracheostomy tube.
Activate suction by covering the catheter opening. Withdraw and rotate the catheter while suction is applied.
The first step is to hyperoxygenate the client using a bag valve mask (BVM) with the nondominant hand. This helps to ensure that the client receives adequate oxygenation during the suctioning procedure.
Next, the sterile suction catheter is inserted into the tracheostomy tube. The catheter is carefully advanced until resistance is met, ensuring it does not force its way in.
After the catheter is inserted, the suction is activated by covering the catheter opening. This creates negative pressure and allows for the removal of secretions.
Finally, the catheter is withdrawn and rotated while suction is applied. This helps to thoroughly suction the secretions from the tracheostomy tube.
