Q

what is one risk associated with taking a rectal temperature?

A

it may stimulate the vagus nerve which may result in bradycardia (slowed HR) and syncope (temporary LOC)

Q

how does age effect body temperature?

A

older and younger individuals may have reduced temperatures

older adults have a reduced capacity to conserve heat and detect cold due to degeneration of nerves

Q

describe febrile and afebrile, what their ranges are, and where these temperatures are taken

A
  • febrile is a pt with a fever ranging above 38 degrees
  • afebrile is a pt without a fever and temp within a normal range (35.8-38.0)
  • taken through tympanic temperatures

Q

what 10 factors may influence pulse/HR?

A
  1. age
  2. disease
  3. stress
  4. exercise
  5. ethnicity
  6. temperature (fever will increase HR)
  7. acute vs chronic pain

Q

how does acute vs. chronic pain influence HR/pulse?

A
  • acute pain will increase pulse rate
  • chronic pain does not create changes in pulse

17
Q

what is the normal range for pulse rate?

A

50-95 beats per minute

18
Q

describe the pulse scale and what each number correlates to

A

0 – absent pulse (cannot feel it or not palpable)
1+ - weak or thready pulse (can barely feel it), diminished, weak, and barely palpable – easy to obliterate
2+ - normal pulse (Obliterate with slight pressure)
3+ - full and bounding pulse (obliterate with firm pressure or unable to obliterate)

19
Q

list the 8 sites for pulse palpation

A
  1. carotid
  2. brachial
  3. radial
  4. popliteal
  5. dorsalis pedis
  6. apical
  7. femoral
  8. posterior tibial
20
Q

what parts of the brain determine resp. rate?

A

medulla oblongata and pons

21
Q

what is a normal range for resp. rate?

A

12-20

22
Q

if resp. rate is coming out as abnormal, how long should you record for?

A

1 full minute

23
Q

what is tachypnea?

A

fast resp. rate above 20

24
Q

what is bradypnea?

A

slow resp. rate - below 12

25
Q

what is dyspnea?

A

difficulty breathing

26
Q

what is hyperpnea?

A

fast and elevated depth - could be caused by exercise

27
Q

what is the difference between hyperventilation and hyperpnea?

A

Hyperpnea is breathing more deeply but not necessarily faster. It happens when you exercise or when you’re doing something strenuous. Hyperventilation is breathing very fast and deeply, and exhaling more air than you take in.

28
Q

what is apnea?

A

no breathing for several seconds

29
Q

what is hypoventilation?

A

low rate and shallow

30
Q

what is the normal range for BP?

A

135/80

31
Q

what is orthostatic hypotension?

A

If systolic drops 20 or more mmHg and HR goes up by 20 beats or more when position is changing

32
Q

What are the three portions of a general survey?

A
  1. Physical appearance
  2. Mobility
  3. Behaviour
33
Q

What 6 components are part of the physical appearance portion of a general survey?

A
  1. Age (appears vs. actual)
  2. sex
  3. LOC X3 or X4 (place, person, time) & (know the situation)
  4. skin colour and lesions
  5. facial features (symmetry)
  6. body structure
34
Q

what component is part of mobility in the general survey?

A

Gait - coordinated or uncoordinated, ROM

35
Q

what 5 parts are part of the behaviour component of general survey?

A
  1. facial expressions
  2. mode & affect
  3. speech
  4. dress
  5. personal hygiene
36
Q

what is the gate control theory?

A

closing the ‘gate’ of sensations from entering the brain to provide a perception of pain

Includes the notion that the perception of pain may be altered by stimulating other sensory pathways that interefere with the transmission of pain messages to the brain

37
Q

what are the 4 sources of pain?

A
  1. somatic - damage to the tissue that creates pain
  2. visceral - anything relating to the internal organs
  3. neuropathic - relating to the nerves
  4. referred - pain that originates from another area and shows in a separate area (i.e., appendicitis, myocardial infarction)
38
Q

What does OPQRSTUV stand for? explain each one

A

o Onset – when did it start?

o Provocative and palliative – what makes it better, what makes it worse?

o Quality – what kind of pain? Can you describe it for me?

o Region/radiation – show me where the pain is

o Severity – pain scale 0-10

o Treatment and timing – what have you done to help it? Does it happen at a certain time of day?

o Understanding – do you think this could be caused by anything?

o Values – how is this pain impacting your life and ADLs? Any limitations due to pain?

39
Q

What is considered as the fifth vital sign?

A

Pain

40
Q

How would you assess pain in an unconscious individual?

A

Individuals will exhibit grimacing, wincing, rigidity, or shaking
