The nurse should first put on gloves before drawing up the irrigation solution into the syringe in order to irrigate an indwelling urinary catheter.
The fluid is then infused using an aseptic method after the syringe is connected to the catheter. The client's catheter needs to be attached to the drainage tube after the irrigation solution has been administered. When intake and output measurements are given, the urinary drainage bag can be emptied, and the irrigating fluid can then be deducted from the output.
A basic human function, the evacuation of urine, can be hampered by disease, surgery, and other circumstances. In individuals who are unable to void naturally, urinary catheterization may be performed to promote urine elimination. It might be necessary to catheterize the urine:
1. When there is sudden urinary retention
2. When intake and outflow are being tracked
3. For preoperative management
4. to speed up healing in patients with incontinence who have open sacral and perineal wounds

Answer:
A patient with a body surface area (BSA) of 0.82 m² should be given 1.64 million of units of Interferon alpha 2b, according to the recommended dose.
Explanation:
Interferon alpha 2b (IFN α-2b) is a biological product used to stimulate the immune system and fight diseases such as hepatitis B and C, leukemia and other types of cancer.
The usual dose of IFN α-2b is 2 to 3 million units per dose, although some circumstances may require a higher dose.
If a patient has an estimated AFB of 0.82 m² and the recommended dose is 2,000,000 units/m²:
IFN a-2b dose = 2,000,000 units/m2 X 0.82 m2
IFN a-2b dose = 1.640.000 UI

Calculate (a) the number of international units and
(b) the micrograms of interferon alfa-n3 proteins administered per dose.
An injection contains 5 million international units (MIU) of interferon alpha-n3 (ALFERON N) proteins per milliliter, so the calculated values are:

(b) 890.3 mg is present in 0.05 ml ordered dose.
What is interferon alpha-n3?interferon alpha-n3 is a purified form of human interferon used to stimulate innate antiviral response to treat genital warts caused by human papilloma virus.
Given that,
Available dose ( Injection) = 5MIU / ml
(interferon alpha-n3 known as ALFERON N proteins per milliliter. )
Ordered dose = 0.05 ml
Activity of Interferon Alpha n3 = 2.6 ×108 IU /mg of protein.
a)
Given that,
5 million IU = 1 ml
5× 0.05 × 10⁶ IU = 0.05 ml
25 × 10⁴ IU = 0.05 ml
Hence, 250000 IU present in 0.05ml ordered dose
b)
Given that,
5 × 10⁶ IU = 1 ml
1 IU = 1/ (5 × 10⁶) ml
and
Given that,
2.6 ×10⁸ IU = 1 mg
or, (2.6 ×10⁸)/( 5 × 10⁶ ) ml = 1 mg
or, 1 ml = (5 × 10⁶)/(2.6 ×10⁸) mg
