Q

difference between medical and surgical asepsis

A
  • Medical asepsis: procedures used to reduce and prevent the spread of microorganisms (hand hygiene, clean gloves = prevent contact with bodily fluids and cleaning environment frequently aids in medical asepsis)

Surgical asepsis: procedures used to eliminate all microorganisms (object considered contaminated when touched by something that is not sterile)

Difference: medical = reduce and prevent the spread of microorganisms & surgical = complete removal of microorganisms

Q

What are the links in the chain of infection and why is it important for psychiatric nurses to understand the infectious process?

A

Infectious agent (pathogen)

A reservoir (source for the pathogen growth (in person, equipment, environment, food or water))

Portal of exit of reservoir (sneezes, coughing)

Mode of transmission (direct, indirect, vehicle, vector)

Portal of entry into host (example: entry through a wound)

Susceptible host

To break the chain so that infections do not develop and reduce risk of passing on infections to patients (importance of hand hygiene)

Select depth on needle on the lancet - 3 settings (shallow, medium, deep)

Poke side of finger with lancet; not pads because they have more nerve endings

To obtain a drop of blood - stroke from wrist, hand to fingertip (avoiding squeezing around puncture site = distorts results)

WIPE away first drop with gauze as this specimen contains greater protein altering results

Press test strip into blood sample – ensure the test strip fills completely with blood

Analyze results, dispose of materials appropriately & document

The sides of the finger

43
Q

What are the 3 parts of the syringe?

45
Q

What are the differences in calibration with the different types of syringes?

A

The difference is based on the volume they hold

insulin syringes are available from 0.3mL to 1mL and calibrated in units (10, 15, 20)

tuberculin syringes calibrated in sixteenths of a minim & in hundredths of a millilitre & has a capacity of 1mL (0.1, 0.15, 0.2)

LEUR-LOK: MEASURES IN TENTHS (2.5, 2.6, 2.7)

46
Q

What are some interventions that the nurse can use to prevent needle stick injuries?

A

Avoid using needles when effective needless systems or sharps with engineered sharps injury protections (SESIP) safety devices are available

Never recap needles

Never move an exposed needle tip toward an unprotected hand

Plan safe handling and safe disposal of needles before beginning the procedure

Immediately dispose of needles, needless systems, & SESIP into puncture-proof containers located near the area of use

47
Q

How do ampules and vials differ?

A

Ampules contain single doses of medication in a liquid, constricted neck that must be snapped off to access the medication and is scored for easy breakage

Vial is a single dose or multi dose contain with a rubber seal, it is a closed system and air must be injected into the vial to permit easy withdrawal

48
Q

Identify the technique for using ampules and vials

A

Ampules: break the scored section of the glass neck in order to gain access to the medication

Vials: air must be injected into the vial to permit easy withdrawal, failure to inject air creates a vacuum within the vial making it difficult to withdraw

49
Q

What is the purpose of a filter needle?

A

Prevent small glass fragments from entering the syringe

50
Q

Identify the technique for mixing medications in one syringe

A

Aspirate a volume of air equivalent to first medications dose (vial A), inject the air into vial A, ensuring the needle doesn’t touch the solution, withdraw the needle and aspirate a volume of air equivalent to the second medications dose (vial B), inject air into vial B & immediately withdraw the medication from vial B into the syringe, then insert the needle back into vial A, being careful not to push the plunger and expel the medication, withdraw the desired amount of medication from vial A into the syringe

51
Q

What kinds of drugs can be administered subcutaneously?

A

Insulin, opioids, heparin, epinephrine, and allergy medication

52
Q

What are the sites for subcutaneous injections?

A

Q

How much medication can be injected via the subcutaneous route?

A

UP TO 2 MLs

54
Q

What is the usual needle size used for a subcutaneous injection?

ALCOHOL SWAB THE SITE, LET DRY, PINCH THE SKIN, INSERT NEEDLE WITH BEVEL TIP FACING UP IN A DART-LIKE MOTION AT 45-90º, DEPENDING ON TISSUE THICKNESS

56
Q

How do you decide whether to inject at a 45-degree or a 90-degree angle for subcutaneous injections?

A

If you can grasp 5 cm of tissue, insert the needle at 90-degrees

If you can grasp 2.5cm of tissue, insert the needle at 45-degrees

57
Q

Why do injection sites need to be systematically rotated?

A

In order to avoid a build-up of fatty tissue which can occur when shots are always given in the same place

58
Q

Do you aspirate by pulling back on the plunger for all subcutaneous injections?

A

NO, NEVER ASPIRATE ON SUBCUTANEOUS INJECTIONS

59
