A client has an arteriovenous fistula in place for hemodialysis. What should the nurse do to assess the patency of the fistula?

Irrigate the fistula with 3 mL of normal saline solution.

Flush the fistula with 1 mL of heparin solution once per shift.

Infuse 50 mL of normal saline once per 24 hours.

Palpate for a vibrating sensation at the fistula site.

Answer and Explanation

The Correct Answer is D

Choice A Reason: Irrigating the fistula with 3 mL of normal saline solution is not a correct way to assess the patency of the fistula, as it may cause bleeding, infection, or dislodgement of the fistula.

Choice B Reason: Flushing the fistula with 1 mL of heparin solution once per shift is not a correct way to assess the patency of the fistula, as it may cause clotting, infection, or allergic reaction.

Choice C Reason: Infusing 50 mL of normal saline once per 24 hours is not a correct way to assess the patency of the fistula, as it may cause fluid overload, hypertension, or edema.

Choice D Reason: Palpating for a vibrating sensation at the fistula site is a correct way to assess the patency of the fistula, as it indicates that there is adequate blood flow through the fistula. This sensation is also known as a thrill.

Correct Answer is A

Explanation

Choice A Reason: Checking blood sugar then eating breakfast prior to injecting insulin indicates that additional teaching is necessary, as it may cause hyperglycemia or hypoglycemia depending on the type and timing of insulin. The client should inject insulin before eating breakfast according to their blood sugar level and carbohydrate intake.

Choice B Reason: Rotating sites from arms, legs, and abdomen indicates that no additional teaching is necessary, as it helps to prevent lipodystrophy and ensure consistent absorption of insulin.

Choice C Reason: Ensuring the use of insulin syringe with units indicates that no additional teaching is necessary, as it helps to prevent dosing errors and ensure accurate administration of insulin.

Choice D Reason: Activating the safety lock on the syringe before disposing in a sharps container indicates that no additional teaching is necessary, as it helps to prevent needlestick injuries and infection transmission.

A. You will remain NPO for 8 hours before the procedure. B. A flexible tube is introduced through the nose during the procedure. C. During the procedure, a contrast dye will be administered via IV. D. You will be awake while the procedure is performed.

Correct Answer is A

Explanation

Choice A Reason:For an endoscopy, the client must remain NPO (nothing by mouth) for 6 to 8 hours before the procedure to reduce the risk of aspiration and ensure a clear view of the esophagus and stomach.

Choice B Reason: A flexible tube is not introduced through the nose during the procedure, but through the mouth and down the esophagus.

Choice C Reason: During the procedure, a contrast dye is not administered via IV, but a sedative and an anesthetic spray are given to help you relax and numb your throat.

Choice D Reason: Clients undergoing an EGD typically receive moderate sedation (such as midazolam or propofol) to help them relax. They are usually drowsy and unaware during the procedure.
