Q

What are 4 ways to troubleshoot a tube feeding?

A

Try clamping tube and allow warm water to “soak”

Try repositioning patient (potential kinks)

Try pushing and pulling back on syringe plunger (gently)

Q

What should you document for tube feedings?

A

Type & amount of formula, patency of tube, stoma sties/skin integrity, response to feeding and side effects

22
Q

What are the 3 distribution systems? Page 742

A

Stock Supply System- meds available in quantity, in large, multidose containers. Time consuming and costly. Eeach med must be dispensed seperatly for each patient- high rate of med errors.
Unit Dose System-portable carts containg a drawer with a 24-hr supply of meds for each patient.
Automated Dispensing System - AMDS are computerized to dispense narcotics and unit-dose medication. Nurse uses security code. Connected to a computer system.

23
Q

What does a low score on the braeden scale mean?

A

The lower the score the higher the risk. Score ranges from 6 to 23

24
Q

Define Primary intention

A

Surgical wound. Edges are approximate or closed and risen of infection is low.

25
Q

What is granulation tissue?

A

Red moist tissue composed of new blood vessels which indicates progression toward healing.

26
Q

What is Slough

A

Soft white or yellow tissue that needs to be removed before a wound can heal

27
Q

What is Eschar

A

Black necrotic tissue which needs to be removed before a wound can heal

28
Q

Define Secondary Intention

A

Wound healing involving loss of tissue such as burn, pressure injury or laceration. Wound is left open until it becomes filled by scar tissue. Takes longer to heal this chance if infection increases

29
Q

What happens during the inflammatory phase?

A

Last approx 3 days
During hemostasis injured blood vessels constrict and platelets gather to stop bleeding.
Clots form fibrin which provides framework for repair.
Damage tissue and mast cells secrete histamine which results in vasodilation resulting in localized redness warmth and throbbing. White blood cells arrive to ingest bacteria and debris. This phase is done to clean the wound bed.

30
Q

What happens during proliferative phase??

A

New vessels appear as reconstruction progresses this lasts 3 to 24 days. Wound fills with granulation tissue. Collagen provides strength and structure. Wound contracts to reduce area of healing.

31
Q

What happens during the remodeling phase of wound healing

A

Takes up to 2 years.
Collagen scar continues to gain strength. Healed wounds are at risk for pressure injury. Fewer pigmented cells is why scars appear lighter.

32
Q

What type of fluid is serous

A

Clear watery plasma

33
Q

What type of fluid is purulent

A

Thick yellow green tan or brown

34
Q

What type of fluid is serosanguineous

A

Pale red watery mixture of clear and red fluid

35
Q

What type of fluid is sanguineous

A

Bright red indicating active bleeding

36
Q

Define eviseration

A

Total separation of wound layers

37
Q

Define dishiscence

A

When a wound fails to heal properly the layers of skin and tissue separate

38
Q

Define intermittent catheterization

A

A single-use straight catheter is introduced urethra Lee for 5 to 10 minutes just long enough to drain the bladder the straight catheter has a single Lumen with a small opening urine drains from the tip through the Lumen into a receptacle intermittent catheterization is performed in patients who have incomplete bladder emptying do two neurogenic conditions. In hospitals this is a sterile technique in community patients clean their catheters and reuse them many times.

39
Q

What is a Coude catheter?

A

Has a curved tip for male patients who have an enlarged prostate that partially blocks the urethra.

40
Q

How much urine can a urinary drainage bag hold

A

1000ml-1500ml

41
Q

What size of catheter for children

A

8 to 10 Fr

42
Q

What size of catheter for female

A

10 to 12 Fr

43
Q

What type of catheter for males

A

12 to 16 Fr

44
Q

What balloon size to be used for a child with a catheter ?

A

3ml is considered pediatric

45
Q

What size of balloon to be used in adult with catheter

A

10ml allows for optimal drainage however 30ml would be used after prostatectomy

46
Q

Why would there be urine leakage around the catheter

A

Bladder spasms secondary to constipation or fecal impaction, the use of a large catheter balloon or a large catheter that causes irritation the presence of a UTI kinking of the catheter or trauma at the bladder neck from traction on the balloon. A change in Lumen size the use of anticholinergic drugs where referral to urologist maybe warranted

47
Q

How many fluids should be in taken for a patient with a catheter

A

2000 to 2500ml.

48
Q

What is orthopnea

A

An abnormal condition in which the person must use multiple pillows when lying down or sit with their arms elevated and leaning forward to breathe

49
Q

What is Hemoptysis

A

Bloody sputum. Normally associated with coughing and bleeding from the upper respiratory tract, sinus drainage or the GI tract. Chest Xray, bronchoscopy, and other xray test to be performed.

50
Q

What is Wheezing

A

Characterized by a high pitched musical sound caused by High Velocity movement of air through a narrowed Airway can occur during inspiration expiration or both.
