5 0

Answer:

a. True

Explanation:

A portal system begins with a set of capillaries and ends with a set of capillaries. Blood comes from one set of capillaries to a a larger blood vessel which drains into another set of capillaries and it is then sent to the heart.

A classic example of portal system is Hepatic portal system. Major function of this system is to deliver nutrients from digested food to liver so that it can be metabolized.  Small intestine absorbs nutrients from the digested food. These nutrients enter the blood in first capillary bed present in intestine. The deoxygenated blood flows through Hepatic portal vein to liver. Inside liver the blood passes through second capillary bed and nutrients are released in hepatocytes. These capillaries join the hepatic vein and the blood is sent to heart via inferior vena cava.

Nurse is using aseptic technique to insert an indwelling urinary catheter. Which technique made by the nurse is correct?
bija089 [108]

The technique made by the nurse is  keeping sterile field above waist level.

<h3>Which technique is made by the nurse to insert an indwelling urinary catheter?</h3>

Similar to an intermittent catheter, an indwelling urinary catheter is implanted, but it is left in place. A water-filled balloon keeps the catheter in the bladder and prevents it from escaping. These catheters are frequently referred to as Foley catheters.

The sole approved usage for indwelling urinary catheters is short-term, or fewer than 30 days (EAUN recommends no longer than 14 days.) Urine incontinence (UI) and urinary retention are two frequent bladder dysfunctions for which the catheter is implanted for continuous bladder drainage.

In order to produce a sterile field, sterile surgical drapes must be placed around the patient's surgical site and on the stand that will contain the sterile instruments and other supplies required for the procedure. The maintenance of a sterile environment is crucial to the prevention of infection. These collection of procedures that are followed before, during, and after invasive procedures help to lower the risk of post-procedure infection by reducing the number of potentially contagious microbes.

Hence, The technique made by the nurse is  keeping sterile field above waist level.
