Correct Answer: A

Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.

Correct Answer: C

Rationale: To maintain patency and ensure proper medication delivery, water should be instilled into the feeding tube between administering the two medications. This helps prevent clogging of the tube and ensures that both medications are delivered effectively without interference from remnants of the previous medication. Diluting the medications with sterile water before administration (choice A) is unnecessary and may alter the medication concentration. Mixing the medications in one syringe (choice B) could lead to interactions or chemical reactions between the medications. Withdrawing fluid from the tube before instilling each medication (choice D) is not required and may increase the risk of tube displacement or misplacement.

Correct Answer: B

Rationale: The correct position for the drainage container after inserting an indwelling catheter is to have it placed lower than the bladder. This positioning helps maintain a constant downward flow of urine from the bladder, preventing backflow and ensuring proper drainage. Choice A is incorrect because having the drainage tubing taut does not promote proper urine flow and may cause kinking. Choice C is incorrect as placing the container at the head of the bed does not affect drainage and is not necessary for accurate measurement. Choice D is incorrect as the positioning of the drainage container should prioritize proper drainage and care over potential embarrassment.

Correct Answer: B

Rationale: Before Mr. Landon undergoes a tracheostomy, the top nursing priority is to establish a means of communication. This is essential to ensure that Mr. Landon can effectively communicate his needs during and after the procedure. Shaving the neck (Choice A) may be necessary for the tracheostomy but is not the top priority. Inserting a Foley catheter (Choice C) and starting an IV (Choice D) are important nursing interventions but are not the priority before a tracheostomy procedure, where communication is key for patient safety and comfort.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to remind the unlicensed assistive personnel (UAP) to dry between the client's toes completely. Failing to dry between the toes can lead to skin breakdown due to excessive moisture accumulation. Proper drying is essential to maintain skin integrity and prevent complications in the client's care. Removing the basin of water immediately may disrupt the care process and not address the root cause of the issue. Advising about potential skin damage is not as direct and actionable as reminding to dry between the toes. Adding skin cream to the water may not be appropriate without specific orders and can potentially worsen the situation by increasing moisture.
