In hemodialysis patients, blood is accessed by the surgical attachment of an artery to a vein known as:

A.

Catheter

B.

Peripheral Intravenous Line

C.

Arteriovenous Graft (AVG)

D.

Arteriovenous Fistula (AVF)

Answer and Explanation

The Correct Answer is D

Choice A reason: A catheter is a flexible tube inserted into the body to allow the passage of fluids or other substances. While catheters can be used for hemodialysis, they are typically considered temporary access points and are not created by surgically attaching an artery to a vein.

Choice B reason: A peripheral intravenous line (PIV) is a catheter placed into a small peripheral vein. PIVs are commonly used for short-term access to administer medications or fluids but are not suitable for the high flow rates needed for hemodialysis and are not surgically created by joining an artery and a vein.

Choice C reason: An arteriovenous graft (AVG) involves using a synthetic tube to connect an artery and a vein. AVGs are used for patients who cannot have an AVF due to small or weak veins. While AVGs are a viable option for hemodialysis, they are not the preferred method due to higher rates of complications like infections and clotting compared to AVFs.

Choice D reason: An arteriovenous fistula (AVF) is the preferred method of vascular access for long-term hemodialysis. It is created by surgically connecting an artery to a vein, usually in the arm. This connection allows for increased blood flow through the vein, which enlarges and strengthens it, making it suitable for repeated needle insertions during dialysis sessions. AVFs are preferred because they have lower rates of complications and provide better long-term access compared to other methods.

Correct Answer is C

Explanation

Choice A reason: This explanation is not correct. The reason why oral medications are not used for type 1 diabetes is not related to the child's ability to take the entire dose. The primary issue is the nature of insulin and how it must be administered.

Choice B reason: This statement is incorrect. The use of insulin injections is not based on age but on the type of diabetes. Type 1 diabetes requires insulin therapy regardless of the patient's age.

Choice C reason: Insulin is a protein that, if taken orally, would be broken down by the digestive enzymes in the gastrointestinal tract, rendering it ineffective. For this reason, insulin must be administered through subcutaneous injections to ensure it reaches the bloodstream intact and can effectively regulate blood glucose levels.

Correct Answer is D

Explanation

Choice A reason: While certain medications can affect bladder control, they are not the primary cause of stress incontinence. Stress incontinence is specifically related to physical exertion and increased pressure on the bladder, leading to involuntary urine leakage.

Choice B reason: Hypertension, or high blood pressure, is not a direct cause of stress incontinence. Stress incontinence is related to the weakening of pelvic floor muscles and increased intra-abdominal pressure rather than blood pressure levels.

Choice C reason: A full bladder can increase the likelihood of urine leakage in individuals with stress incontinence, but it is not the underlying cause. Stress incontinence occurs due to weakened pelvic floor muscles and increased pressure during physical activities.

Choice D reason: Stress incontinence occurs due to exertional stimuli that increase intra-abdominal pressure, such as coughing, sneezing, laughing, or physical exercise. These activities cause a sudden increase in pressure on the bladder, leading to involuntary urine leakage. The condition is often associated with weakened pelvic floor muscles, which can result from factors such as childbirth, aging, or pelvic surgery.
