Q

As s nurse you can delegate to a CNA but you are responsible for oversight

A

oui. However if the pt has diabetes for example and they have a hang nail the nurse has to do it because they can develop an infection.

The microorganisms that usually occupy a particular body site are called the resident flora. Cells of the resident flora outnumber a person’s own cells 10 to 1. Microorganisms that colonize people for hours to weeks but do not establish themselves permanently are called transient flora.

Q

The Portal of Exit from the reservoir. This describes the way the microorganism leaves the reservoir. For example, in the case of a person with flu, this would include coughing and sneezing. In the case of someone with gastro-enteritis microorganisms would be transmitted in the faeces or vomit. potal of entry is the opposite

Q

Exogenous infections

A

Exogenous infections, in contrast, involve a pathogen entering a patient’s body from their environment. These pathogens can be introduced through a contaminated device, a healthcare worker like an IV, a surface, or a patient in the same room with another one. covid spread in a hospital.

A
39
Q

core temp deep in tissues stays constant

A
40
Q

surface temp on skin

A

changes with environemment

41
Q

temp is regulated in the hypothalamus and it acts as a thermostst

A

when the temp is under 36/98.6 you start shivering you get goosebumps your veins become invisible because they shrink from the surface to conserve heat

when the temp goes up you sweat, increase in resp rate to lose heat through evaporation
vessels close to the surface to lose heat.

42
Q

older people, children, have a hard time regulating their temp and newborns can’t shiver.

A
43
Q

factors affecting heat are BMR, exercise shivering and fever(caused by a change of the set point hypothalamus)

A
44
Q

convection
loss of heat due to air currents

A
45
Q

axillary temp (surface)
oral route (surface)
Temporal (core temp but not necessarily reliable)
IG only if necessary. contraindicated in young children to avoid puncturing the rectum. Not ok with hypotension coz it can cause disarrthmias. not ok with low platelets due to the risk of bleeding. not ok with spinal injury

A
46
Q

Pyrexia is fever (aka true fever). It happens when the body when the hypothalamus changes the set point to kill a pathogen and its pyrogen (substance released by bacteria) Once pathogen is killed you are going to be sweating to lose heat

A
47
Q

Types of fever:

A

sustained : constant above 38/100.4 with little fluctuation
intermittent : temp returns to normal every 24h
Remittent: fever spiked with no return to normal temp levels.
Relapsing periods of febrile episodes and periods of acceptable temp values

48
Q

Normal temp?

A

36-38 C
96.8 - 100.4 F

49
Q

hyperthermia does not have a change in the set point of the hypothalamus it’s just high heat due to external temp and it can lead to a heat stroke which is when you lose your ability to sweat and lose electrolyes.
Alcoholics suffer from hypothermia, the very young and old as well.

A
50
Q

Normal pulse

A

60-100

51
Q

Stroke volume

A

The amount of blood pumped in one heart beat

52
Q

cardiac output

A

the amount of blood pumped in 1 min

53
Q

dorsalis pedis aka

popliteal

femoral

A

pedal pulse next to that big tendon that goes to the big toe

back of knee

ingle

54
Q

beta blocker decrease heart rate

A
55
Q

What is orthostatic bp and when does it happen?

A

Happens with poeple who have bad perfusion usually old. it is a reduction of systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg within 3 minutes of standing. coz the heart needs some

56
Q

apical pulse: The point of maximal impulse, known as PMI, is the location at which the cardiac impulse can be best palpated on the chest wall. Frequently, this is at the fifth intercostal space at the midclavicular line.

A
57
Q

A doppler is used when?

A

There is a difficulty palpating a pulse.

58
Q

tachycardia

A

heartbeat that is faster than 100 bpm

59
Q

Baricardia

A

heartbeat that is less than 60 heartbeat per min

60
Q

Arrhythmia

A

irregular heart beat

61
Q

pulse deficit is used to check for perfusion

A

it is the difference between 2 points. Ex: if the apical is 70 and the radial is 60. We do this to check for perfusion. because the pulse deficit is more than 2 then we have a pulse deficit.

62
Q

The normal rate for respiration

A

12-24
If someone has 12 breaths per min don’t give them opioids so that they don’t go into respiratory distress.

63
Q

The resp center is the medulla oblongata in the brain

A
64
Q

Dyspnea

A

difficulty breathing

65
Q

Apnea

A

Temporary absence of breathing

66
Q

Orthopnea

A

difficulty breathing when laying flat

67
Q

Systolic pressure and normal value?

A

The first sound that you hear. It happens due to contraction of the ventricles.
90/120

68
Q

Diastolic pressure and normal values

A

The last sound that you hear when you are taking BP. it’s because the ventricles are filling with blood.
Normal is 60/80

69
Q

Stages of hypertension. elevated systolic bp?

A

systolic between 120/129 and diastolic less than 80 (which is normal)

70
Q

Stage 1 Stages of hypertension

A

systolic between 130/139 or diastolic between 80/89

71
Q

Stages of hypertension stage 2

A

systolic at least 140 or diastolic at least 90

72
Q

Stages of hypertension hypertensive crisis.

A

Systolic over 180 and diastolic over 120

73
Q

Hypotension?

A

systolic under 90

74
Q

Orthostatic hypotension aka postural hypotension.

A

drop by 20 in systolic pressure and 10 in diastolic

75
Q

Diurnal variations bp

A

Usually, blood pressure starts to rise a few hours before a person wakes up. It continues to rise during the day, peaking in midday. Blood pressure typically drops in the late afternoon and evening. Blood pressure is usually lower at night while sleeping.

76
Q

White coat syndrome

A

bp normal at home but not at the doctor (nervousness)

77
Q

Rectal temps are the most accurate. Forehead temps are the next most accurate. Oral and ear temps are also accurate if done properly. Temps done in the armpit are the least accurate.

A
78
Q

Cuff too big = low bp
cuff too tight= high bp

A
79
Q

methods of getting BP.

A

Invasive direct into the artery
indirect includes auscultatory and palpatory
korotkoff sounds heard in auscultation of bp
Position limb: take a heart level

80
Q

Orthopnea is the sensation of breathlessness in the recumbent position, relieved by sitting or standing.

A
81
Q

Orthopnea

A

Orthopnea is the sensation of breathlessness in the recumbent position, relieved by sitting or standing.

82
Q

A surgical mask has a shield this is why it is droplet proof

A
83
Q

Look at past trends when assessing temp and vital signs in general such as respirations and heart rate

A
84
Q

Axillary temp is affected by the environment because it’s surface temperature. n the NICU, the temperature is often measured at the axilla rather than the rectum as it is more accessible and less invasive.

A
85
Q

Newborns and children under 5
temp is best in the axilla

A
86
Q

No bP reading in a mastectomy.

A
87
Q

The general concern about rectal temperatures post-MI is that it might stimulate the vagus nerve and cause bradyarrhythmias.

A
88
Q

laparoscopy vs laparotomy

A

Laparotomy is basically a surgical procedure which involves a large incision in the abdomen to facilitate a procedure. While laparoscopy is a minimally invasive surgical procedure which sometimes referred as keyhole surgery as it uses a small incision.

89
Q

Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you’re allergic to, such as peanuts or bee stings.

A
90
Q

Hypovolemic shock is an emergency condition in which severe blood or other fluid loss makes the heart unable to pump enough blood to the body.

A
91
Q

Thrombophlebitis (throm-boe-fluh-BY-tis) is an inflammatory process that causes a blood clot to form and block one or more veins, usually in the legs
