Medicine
1 answer:
Brrunno [24]3 years ago
6 0

Answer:

The correct answer is C.

Explanation:

Blood enters the heart through the superior vena cava and the inferior vena cava into the right atrium. When the right atrium contracts, this poor oxygen blood flows to the right ventricle through the tricuspid valve. The valve then closes and the right ventricle contracts ejecting blood through the pulmonary trunk and pulmonary arteries to the lungs to be oxygenated.

Pulmonary veins carry oxygen-rich blood from the lungs into the left atrium. Then the atrium contracts and blood flows from your left atrium into your left ventricle through the mitral valve. The valve then closes, the left ventricle contracts and blood leaves the heart through the aortic valve, into the aorta and to the body.

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.
